@CodeXYZ I've been using it for 2-3 days now and it seems to work without problems.

Thank you @ZappaBoy that saved me so much time :)

[EDIT] BTW I didn't test this at all so make sure you lmk if it's working

I hope i'm doing it right. Updated to version 1.8.2; Moved from aramg/droidcam to dev47apps/droidcam

libappindicator-gtk3 now runtime dependency. Droidcam won't start without it.

@CodeXYZ Working on my end. Thank you very much. Very much appreciate it

I cant test rn but let me know if its working!

Apologies. Don't mean to rush you. Take your time. As long as there maintainers, I am happy and grateful. Life happens bud - get to it when you can.

Thank you for asking srahman5317 No, I've just been busy. I'll get this updated today asap!

This package has been marked as out of date, and I believe there is a newer version of droidcam available. Is there an issue with the newer versions or is the issue with maintainence? Just asking.

@lazerl0rd why does your patch provide V4L2LOOPBACK-MODULE? I thought v4l2loopback-dmks is the one to provide it?

I'm not sure if you want to be co mantainer but since you added your name on that diff I'll add you as one anyway @lazerl0rd I'll update this package in the next coming days if I get time but do feel free to update it if you'd like :-)

Could you merge this patch, please? I've added two links just in case one fails.

https://pastebin.com/ddrZsZqJ https://katb.in/wixorageqog.patch

A user here is reporting that the loopback device is breaking pulseaudio for them

https://bbs.archlinux.org/viewtopic.php?pid=1998818

Just thought I would mention it

@rachejazz I still got the same error. Don't know if this helpful but it worked flawlessly on a debian system I had used earlier.

Yeah I'm pretty confused about that. I'll see if I have time to work on this package this week. Let me know what else is wrong with it.

v4l2loopback was not loaded by default on my arch for some reason. I did have to install and load it manually. Otherwise, it gave this error:

Error: Droidcam/v4l2loopback device not found (/dev/video[0-9]).
Did it install correctly?
If you had a kernel update, you may need to re-install.
Audio loopback device not found.
Is snd_aloop loaded?
Client v1.8.0
Video: 
adb: error: internal error
Error: Error adding adb forward!

Does anyone think keeping v4l2loopback as a necessary dep should be considered? I have read in the comments that v4l2loopback-dkms is optional. So why is droidcam installing it?

@alerque Thank you very much!

@santilococo This package can be uninstalled using pacman just like any other package you install. It does not load the module, so however you loaded it on your system should be reversed by you. There are several potential ways that could happen. If you did nothing, then you don't have to do anything after installing. If you loaded it manually some way, reverse what you did.

Hi! Do you have a script for uninstalling? (Unloading the loopback module for example). TY.

As @simona has said, the dependency should be changed to v4l2loopback-dkms. Having a different module interfering with other applications for me.

Looks like it's still in /usr/bin @alerque Thanks for the tip though :-)

When you update to 1.8.0 be sure to configure the PREFIX, upstream changed the default to be /usr/local but for packages this should be /usr.

It's been so long and I'm so rusty. Had to learn all the basics again ha! Should be good now let me know otherwise.

As lots of people here already mentioned libappindicator-gtk3 should be part of the required dependency. The build fails without it. Please commit a change for that.

The client works with the standard v4l2loopback module, and installing v4l2loopback-dc is optional. Standard v4l2loopback usage examples. The standard v4l2loopback module is already available on most distros. Better change deps to v4l2loopback* ?

droidcam is ok also with v4l2loopback-dkms (community) instead v4l2loopback-dc-dkms ?

Easy fix for manjaro.

https://forum.manjaro.org/t/root-tip-get-droidcam-working-on-manjaro/1233

Sorry, I haven't had a working laptop for a bit now, so even though I can probably update and fix the package, I don't have a reliable was to build and test it at the moment. I am reading the comments here about it though.

Hmm, perhaps splitting out one more package, namely "droidcam-cli" would be a way to go here then. So "droidcam" can depend on all GUI-related libraries. This will still allow people to install CLI-only version. What do you think?

I agree with @s1lv3r this package fails without libappindicator-gtk3.

I believe libappindicator-gtk3 should be added to the required deps instead of the optional deps

This new version requires app-indicator.h from the package libappindicator-gtk3.

The only way to make droidcam work at first shot and without need to worry about anything is this: https://www.dev47apps.com/droidcam/linuxx/ Follow instructions and it'll take less than one minute (download included)

I believe linux-headers should be added as dependency.

@lorcap see https://wiki.archlinux.org/index.php/DKMS_package_guidelines#Dependencies why headers should not be in dependencies.

==> WARNING: backup entry file not in package : etc/modprobe.d/droidcam.conf

This seems indeed like a bug. This file should only be backed up for v4l2loopback-dc-dkms package, not for both of them.

I believe linux-headers should be added as dependency.

It took me a while to figure out why droidcam complained about a missing kernel module despite the package compilation and installation succeeded. Then I reinstalled the package and noticed the following error:

==> Unable to install module v4l2loopback-dc/1.7.2 for kernel *: Missing kernel headers.

which I fixed by installing linux-headers.

When running makepkg, I get the following warning:

...
==> Checking for packaging issues...
==> WARNING: backup entry file not in package : etc/modprobe.d/droidcam.conf
...

Could you add v4l2loopback-dkms as an alternative dependency to v4l2loopback-dc-dkms, since either of those packages will do the job?

@invidian Yes that seems to be the cause for my problem. Removing it via modprobe -r snd-aloop brings my internal soundcard back. For now I decided to just remove snd-aloop from /etc/modules-load.d/droidcam.conf and try to use my internal microphone instead of the one of my smartphone.

@patchcard2 perhaps this is because we load snd-aloop kernel module?

For some reason, after installing this package ALSA did not recognize my internal soundcard anymore: snd_hda_intel 0000:00:1b.0: cannot find the slot for index 0 (range 0-1), error: -1

@maximbaz thanks for explanation! I replaced ../.. with ${srcdir} then.

@invidian: it fails as hexhu describes when you build in isolated environment in chroot, e.g. install devtools package and run extra-x86_64-build.

I would suggest avoid using relative paths and just use ${srcdir} in place of ../../

@biker The link is correct. We build multiple packages using single repository, as the source of both packages is the same.

@gbc921 did you try loading v4l2loopback or v4l2loopback-dc kernel module? Because the former is indeed provided by "v4l2loopback-dkms" package and the latter is provided by "v4l2loopback-dc-dkms".

@hexhu I've tried building the package in Arch Linux Docker image (Dockerfile in this package repository) and things work just fine. How do you invoke package building so you hit this issue?

Getting

==> Starting package_droidcam()...
/dev/shm/makepkg/droidcam/src/droidcam-1.7 /dev/shm/makepkg/droidcam/src
install: cannot stat '../../droidcam.desktop': No such file or directory
==> ERROR: A failure occurred in package_droidcam().
    Aborting...

for 1:1.7-1.

Please change line 55-56 of PKGBUILD to

  install -Dm644 "../${pkgbase}.desktop" "$pkgdir/usr/share/applications/${pkgbase}.desktop"
  install -Dm644 "../${pkgbase}.conf" "${pkgdir}/etc/modules-load.d/${pkgbase}.conf"

as a fix.

Also v1.7.1 has just been released, which dropped 'appindicator' (systray icon) support.

On my system I had to install v4l2loopback-dkms as well to be able to load the module. Not sure it is due to using linux-lts.

Is this true for anybody else?

Would expect "Git Clone URL" linking to "https://aur.archlinux.org/v4l2loopback-dc-dkms.git instead of "https://aur.archlinux.org/droidcam.git"!?

For Manjaro users and anyone else having issues: https://archived.forum.manjaro.org/t/howto-droidcam-on-manjaro/149030

Hey @madskjeldgaard. libappindicator is marked as optional, as you may run Droidcam from CLI only. Maybe it would make sense to create a droidcam-cli or droidcam-gtk packages...

should libappindicator be a non-optional dependency? I tried running without it and got errors so I think it is required.

Thanks!

Why droidcam-icon.png is installed in /opt ?

I tested with v4l2loopback-dkms on my Manjaro (yes, I read the pinned comment) and I needed to change three things, remove videodev in /etc/modules-load.d/droidcam.conf, leave only v4l2loopback in place of v4l2loopback-dc (that was obvious).

The third modification is to add /etc/modprobe.d/droidcam.conf to the droidcam package, the program works without this change, but the user cannot change the resolution.

Without the above changes my system has errors to start, I'm not complaining, I'm just passing on the information, maybe it can be useful.

Greetings.

With 1.6 supporting both, I think it would be preferable to drop the goofy custom loopback module and just depend on the regular v4l2loopback module / package.

I updated to 1.6, but didn't add v4l2loopback support yet, as I'm not sure how to handle it yet and we discuss it with other maintainers.

In the meanwile, one can manually install v4l2loopback-dkms package, unload v4l2lookback-dc module and load v4l2loopback to try it out.

Could you add snd-aloop to droidcam.conf so sound works a bit more OOTB?

@fourier No, as stated in https://wiki.archlinux.org/index.php/DKMS_package_guidelines#Dependencies.

@invidian thanks, that's what I did. But shouldn't the headers be installed as a dependency?

@fourier you must install kernel headers for the kernel you have installed in order to use DKMS, for example "linux-headers" if you use "linux" package for your kernel. See https://wiki.archlinux.org/index.php/Dynamic_Kernel_Module_Support#Installation for more details.

Tried to install, but failed with

==> Unable to install module v4l2loopback-dc/1.5 for kernel *: Missing kernel headers.

@klingt.net hmm, I don't know what could be the cause then. This repo contains a Dockerfile which I use to test builds on fresh machines, to make sure all dependencies are included. Maybe try manually cloning the repository and building from there?

@invidian

I have the latest available version installed:

$ yay -Qi libjpeg-turbo | grep Version
Version         : 2.0.5-2

@klingt.net maybe you have outdated version of "libjpeg-turbo"? It seems compiler picks the version, which do not have "tjGetErrorStr2" defined, which has been added in 1.5.3+: https://github.com/libjpeg-turbo/libjpeg-turbo/releases/tag/1.5.90.

error making: droidcam (v4l2loopback-dc-dkms)

@pickfire thanks for noticing, you are right. I added "libappindicator-gtk3" as optional dependency now, as we do the same with "gtk3", given that "droidcam-cli" works without both of those packages.

I wonder, perhaps this optional dependencies should be dropped and just added as regular dependencies.

libappindicator-gtk3 is a dependency, not just make dependency. Otherwise, droidcam

droidcam: error while loading shared libraries: libappindicator3.so.1: cannot open shared object file: No such file or directory

jonseitz I suspect that happens, because you have "." in your PATH, so local "install" script takes precedence over "global" "install" binary. I'll fix that, it seems like a reasonable case.

Ran into an issue installing just now, getting the following error:

It seems that the issue is that the calls to install ... in the package scripts were referencing the install script in src/droidcam-1.4/linux/, instead of /sbin/install. I was able to get it working by changing the PKGBUILD to:

Possibly it's something specific to my system, but dropping this here in case anyone runs into the same.

first, I wanted to thank the maintainers. Secondly, there is an easy fix for manjaro users. You just need to install kernel headers specific to your kernel version. So after installing linuxXX-headers, reboot and then install droidcam.I've tested it and it works perfectly fine. Best of luck!

@LenLord That's the problem, I've already did this before to try the installation of DroidCam: [albert@ThinkPad ~]$ sudo ln -s /usr/lib/libusbmuxd.so /usr/lib/libusbmuxd-2.0

And the build still the crashes...

UPDATE: I've found the issue, it missed the .so in libusbmuxd-2.0

Regards and thank you very much!!

@acutbal As I wrote early to link you need to specify location where is libusbmuxd and execute "sudo ln -s YOUR_LIB_LOCATION /usr/lib/libusbmuxd-2.0.so" replace YOUR_LIB_LOCATION with your path

@LenLord Thank you very much for your help, I've found libusbmuxd.

I've searched on the Arch wiki how to link a file from an AUR package but I haven't found it. Please, could you suggest me a place where to learn it? Thank you very much and regards.

@acutbal Try to find libusbmuxd.so in your system and link it. Command - whereis libusbmuxd

@LenLord Yes, it's installed, v.2.0.1-1. Weird...

Regards.

@acutbal did you install libusbmuxd? if not install and link it, if needed.

@LenLord I've tried your suggestion but it doesn't work, the build still crashes. I've searched on my system the file "lusbmuxd-2.0" and it doesn't exist.

Regards.

@flashy sudo ln -s /usr/lib/libusbmuxd.so /usr/lib/libusbmuxd-2.0.so try it

@invidian I have read the pinned comment, however the patch breaks the build on manjaro with "/usr/bin/ld: cannot find -lusbmuxd-2.0". I'm not entirely sure where to report this if not here.

Thanks for reporting @dwzg. I didn't have a chance to check building on fresh installation due to poor internet connection. I added missing dependency now.

Installation of the newest version of v4l2loopback-dc-dkms gives an error about a missing header file "usbmuxd.h". This can be fixed by installing libusbmuxd. I guess this is a missing make dependency.

https://github.com/dev47apps/droidcam-obs-plugin/ is available now if you're interested. Basically obs-specific plugin (needs a different android app too).

Thanks @maximbaz. I pushed the update which introduces split package.

invidian I have approved the request, please go ahead with creating a split package :)

@lorcap DKMS optionally depends on 4 headers available in main repos, regular, LTS, hardened and zen. That's kinda expected to have one of these installed if you use DKMS

I had to install core/linux-headers for having the module properly built and installed. I believe that PKGBUILD misses a 'depends' on 'linux-headers'.

Split packaging from the droidcam package as droidcam-dkms sounds like the best way to go to me. Thanks for working on getting this cleaned up.

@ShayBox, this package is a kernel module used by droidcam, but packaged separately, so we can use DKMS hooks, so it does not break during kernel upgrades.

IMO 'droidcam-dkms' for package name is a bit counter-intuitive.

Actually, this package was not created very thoroughly, so I requested a merge into the 'droidcam' itself, so we can use split packaging feature there, to build both this one and the Droidcam itself.

@M.Srikannth, we currently have no solution. We might have to ask the developers to solve it, they'd understand the issue better.

Please don't source un versioned files (icon2.png, droidcam_latest.zip) in a non git package if possible, add the file to the repository, use a set commit, or skip verification.

What is the point of this package when droidcam, droidcam-dkms, and droidcam-dkms-git exist, is this a custom build of v4l2loopback by the dev of droidcam? or is this a kernel module for droidcam, if the prior, please provides and conflicts v4l2loopback, if the latter, do the same for the above packages.

@micwoj92 oops, I'm aware of that, my bad, sorry!

Hey man, when you update package version, you should set pkgrel to 1

@LevitatingRain,is there any progress in getting snd-aloop to work?

Cool, thanks!

@Terence thanks for suggestion, added. I just saw this pattern today in some other package ;)

Hey, can you make the URL point to https://github.com/aramg/droidcam instead? This is a more useful link as you can see what changed between version. Also now instead of ${pkgname}-${pkgver}.zip::https://github.com/aramg/droidcam/archive/${pkgver}.zip" you can use: ${pkgname}-${pkgver}.zip::${url}/archive/${pkgver}.zip"

@caleb it builds from Git tag from Github, how is this URL unversioned? The tags on GitHub should not be modified after publishing. How is it not installing the right version then? The md5 sums of source files for kernel modules all matches, if you compare them from the package and right git tag.

Please use the Github sources with taggged versions, this is using an unversioned upstream URL that breaks the checksum on update and currently isn't installing the version the package claims to be.

@M.Srikanth, we are still working on a solution to get sound working. Simply adding snd-aloop to droidcam.conf makes the module load but snd-aloop also needs to be configured to use the loopback soundcard, which the ID of changes when you remove/add other soundcards. The solution provided by droidcam sets the ID at install time but this very error prone.

Can you add snd-aloop to droidcam.conf

@caleb

I have some plans on bringing this to the official repos, but not completely sold on this yet. I'll switch to git sources, and, as much as I hate using epochs, I don't see a way around it.

The versioning come from the way upstream used to release on their official website, it had that versioning. Since they switched to using only "latest", I have been arbitrarily increasing the pkgver.

now ok :-))))

I fixed the source URL for 1.2, please make sure you're downloading new source archive when building.

@caleb,I thought that it was downloading the same zip as in dev4apps.net but now I realised it is different(by binary zip I meant the contents of the zip is a droidcam binary). (But still that issue remains with the zip from dev4apps.net though)

EDIT:It actually was the same thing as in dev4apps.net until 1 hour ago

The sources for this seem to be available here. Since the sources are available I think this needs to use them — or get renamed as -bin. I think you'll need an epoch to downgrade the version, but where is the 6.x versioning coming from anyway?

@M.Srikanth The zip file itself droidcam-1.2.zip is binary (all compressed archive formats are) but the contents in the sources from this repository. Of course it has has a Makefile!

droidcam-1.2.zip is a binary zip. But for some reason it has a Makefile (which fails).Also the directory layout is changed and support for audio is added.So the PKGBUILD should be rewritten.

==> Starting build()... /home/barfin/.cache/yay/droidcam/PKGBUILD: line 29: cd: droidcam-1.2/linux: No such file or directory ==> ERROR: A failure occurred in build(). Aborting... Error making: droidcam

The current PKGBUILD is downloading the wrong source file from the Github repo (the correct one is 1.2.zip). The following package download string (+ redownload and rehashing) fixes the build failure that miss_barfin got for me:

"${pkgname}-${pkgver}.zip::https://github.com/aramg/${pkgname}/archive/${pkgver}.zip"

==> Starting build()... /home/barfin/.cache/yay/droidcam/PKGBUILD: line 29: cd: droidcam-1.2/linux: No such file or directory ==> ERROR: A failure occurred in build(). Aborting... Error making: droidcam

Thanks for insights @malbeth. It is indeed the case. If found that the PKGBUILD wiki page says, that downloaded source file must have unique name, so I changed it now

AwesomeHaircut, again we only have to change the filename. I'll make a commit with the change sometime tomorrow. I'll also look into the sound script.

Anyone setting SRCDEST with makepkg will have similar issues.

Neither Yay or any other aur helper are officially supported. The makepkg command is the only way I test and only way i support.

Like Foxboron said, this package fails to update if using an AUR manager with a cache (like yay), since the droidcam.zip file name never changes (doesn't include the pkg version) the latest file doesn't get downloaded and the build fails at the checksum check.

Please update the PKGBUILD file with his solution.

This package fails to update when using an AUR manager with a cache (like yay), since the droidcam.zip file name never changes (doesn't include the pkg version) the latest file doesn't get downloaded and the build fails at the checksum check.

The dkms dependency will be worked on upstream, but that will hopefully come soon and there won't be a need for loading.

@Marc.337

The version on github is 1.1. This is a problem. The fact is, upstream never bothered with consisting versioning.

I just tried removing all yay's cache manually and that worked. I did notice v4l2loopback-dc doesn't get loaded automatically though.

@LevitatingRein I just tried building with yay with removed cache and everything seems to work.

Yay complains that droidcam.zip has a wrong sha512sum. Building the package manually works though.

Thanks @Kalq, sorry about that. I pushed new version with added proper dependencies. If you use only the CLI version, then gtk2 is only needed while building, so I'm not sure if it should be added to the dependencies. I leave it in makedepends for now.

@grazzolini, I understand you plan to switch this to pure source; in the meantime, why not pulling the release tag from GitHub? See https://github.com/aramg/droidcam/releases.

Hi, I think libjpeg-turbo, alsa-lib, ffmpeg, and gtk2 should be makedepends. I couldn't get it to work without them. I think gtk2 is not optional.

@miss_barfin thanks for the heads up. I'm looking into the "install-sound" script right now and it seems to me that it's rather hacky. E.g, if you change number of sound cards in your system, it will break anyway.

The reason the script does not work is because v4l2loopback-dc-dkms installs /etc/modprobe.d/v4l2loopback-dc.conf, instead of /etc/modprobe.d/droidcam.conf. I guess doing sudo ln -s /etc/modprobe.d/v4l2loopback-dc.conf /etc/modprobe.d/droidcam.conf should work around that.

problem, audio doesn't work you need to run "install-sound" script after installation in order to use audio but i can't really do it because it thinks the droidcam isn't installed because it can't find the file "/etc/modprobe.d/droidcam.conf"

There's been lot of changes to this package in the last couple weeks. There's also been changed to droidcam itself. Sorry for the delays and remember we all do this in our free time.

There's been an actual release by the droidcam dev, so hopefully that means things stabilize for now.

We now depend on v4l2loopback-dc-dkms, but now we are also depending on invidian to update that package in time. And it seems like the sha512sums are already outdated...

Can't we just depend on v4l2loopback-dkms instead? Edit: No we can't Droidcam refuses to use that one.

Manjaro is spam here, and the maintainer already said he can't install a different distribution just to support some users. Manjaro users: Please refrain from making further comments and use Manjaro support channels instead.

I have unpinned and removed the pinned comment suggesting people to install the make with sudo make install. This is silly. This is a packaging problem where the author does not account for a shared SRCDEST.

This is solved with "${pkgname}-${pkgver}.zip::https://github.com/aramg/${pkgname}/archive/${_pkgver}.zip". Any other workarounds are wrong.

i flagged this out of date but i saw that you're already aware of the change thanks for packaging it

Upstream switched from putting versioned files on their website, to using a fixed name that has no version information. It only says "latest". So, everytime they update their version on the website, the checksum on the PKGBUILD will be outdated. This is not an issue with the package itself, but with the way upstream release. I plan on changing to a pure source package soon, once I get this building from source but, until then, if you get a checksum error, download from their website and change the PKGBUILD.

Managed to get this to install after side stepping verification (Big Trust issue!!)

I see the following:

I see others having a similar issue, Why is this failing to build the module? What's missing from your package that's stopping this?

This is the only kernel I use so no need to ask "Is that the kernel you've booted?"

I decided to do a system wide find: sudo find / -name "v4l2loopback-dc.ko"

Still not found!!!!

What are you doing?

@grazzolini

Of course, sorry for being so cryptic. When I run "sudo modprobe v4l2loopback-dc" I get that error message, like @artemklevtsov.

It could possibly fix the issue I'm having currently on Manjaro 20.0.1. (on 5.4, 5.5, 5.6 and 5.7) The issue is; if I start DroidCam I get the following error: Error: Device not found (/dev/video[0-9]). Did you install? [OK]

I totally assume it is something I butchered in my environment, somehow, but I thought, since @artemklevtsov is trying a solution similar to what I've found elsewhere, it might be somehow related to recent updates kernel side.

@Arndroid

Never got any errors like this, can you be more specific?

Has there ever been a solution for the v4l2loopback_dc Exec / Bad address errors?

Hi, the checksum for droidcam-6.7.6.zip seems to be incorrect, which means the package can't be installed. Could you please correct it?

Also with the workaround doesn't work....

i get

Registering webcam device modprobe: ERROR: could not insert 'videodev': Invalid argument

EDIT: It worked... I need just to reboot a try again.... Thanks a lot...

Note:Some AUR helpers do not redownload droidcam.zip as it has the same name and then complain it has wrong md5sum

works works works ;-)

fixed fixed

nope still issue with droidcam.tar.bz2 checksum This is what I get

wget https://www.dev47apps.com/files/linux/droidcam_latest.zip

The last key looks wrong to me ...

This works like a charm!

)

Is this working for you guys? I checked and it updated but the checksums matched.

Hi

Using arch: makepkg - o fails

It cannot validate (md5sums check) droidcam.tar.bz2

Same error wether I try wiki instruction to install AUR package or your workaround.

Thx for maintaining this package.

NB: droicam seems to work now also on ios.

Same problem with @ManjaroUsar. Using 5.6.8-arch1-1.

It gives me a ==> ERROR: One or more files did not pass the validity check! when I install it (I tried with yay and the pamac gui). I use manjaro on Linux 56 kernel, and I had the headers installed. The download snapshot method gave the same error.

I'll do some extra testing on Arch and if it works I'l add the patch. (As soon as I am behind my terminal).

montefuscolo's fix worked for me. Thanks. 5.4.35-1-Manjaro.

I did this changes on Manjaro

The v4l2loopback_dc doesn't get updated with the kernel properly. You have to reinstall droidcam everytime you kernel updates... Would be nice, if dkms would be implemented

I'm getting an error during installation:

insmod: ERROR: could not insert module /lib/modules/5.5.13-arch2-1/extramodules/v4l2loopback_dc.ko.gz: Unknown symbol in module
error: command failed to execute correctly

I tried compiling the module from source and then invoking insmod manually. But the same error occurs. Not knowing much about kernel modules I have no clue how to fix this.

@henriquelalves wow it worked! though it didnt worked with Yay, but i was able to install using sudo sh ./install , thanks brother!

@smokehead, I had the same problem during make on Manjaro ("No targets specified and no makefile found"). I was actually missing the linux54-headers (just installed it with pacman -S linux54-headers). The installation worked after that. Link where I found the solution: https://forum.manjaro.org/t/cant-build-v4l2loopback-dkms-package/129706

I am on linux5.7 kernel and I also cant install. I get errors for VFL_TYPE_GRABBER not being declared.

I wondered that too when I adopted the package. I think it's against Aur guidelines to do it exactly the same way. I've experimented with it and it's definitely doable.

@milk I am wondering why the installer doesn't use the installer that comes with the program, which should handler a lot of extra driver stuff and tell you this automatically. Anyway I could add that if I find the time.

Maybe worth adding a post install echo of the resolution changing instructions.

Edit: I did a clean build and it built :)

I have the same issue as milk.

milk, I didn't have the same issue you are facing, which is odd. I recommend you run makepkg with the --skipchecksums flag.

They might've already updated the latest version since my commit. I'll update the md5 hash in a couple of minutes.

Currently getting:

Like M.Srikanth mentioned I started using the new source. I am currently compiling the latest kernel so I can test it. But it's all working on 5.5.5-zen.

For me too.. With Kernel 5.6.2 and 5.6.3, it fails to build

With Kernel 5.6 ,it fails to build

@tomvigl - that readlink change did not work for me. I had to use the solution from

@montefuscolo - although your solution appeared to work, I could not change the resolution at all - it was stuck at 320x240 ...uugggghh

@AwesomeHaircut - the pinned workaround works fine - now I am able to change the resolution as described at https://www.dev47apps.com/droidcam/linuxx/

thanks all.

@AwesomeHaircut: You just have to add readlink and it won't affect the installation in arch. MODPATH=$(readlink -f "/usr/lib/modules/$(uname -r | sed 's/.[0-9]+-[0-9]+//')/extramodules")

I don't want to say "Manjaro is not supported" but that's what is officially true. The module loading is depended on where you have your extra modules folder that can be, and probably is, different on manjaro. I have to make sure it works on Arch first and foremost. I just don't have time to install manjaro right now to test.

Having said that, you can load the module manually by going into the source directory no matter which distro you're using. I won't be making any changes, but I'll make a short tutorial for manjaro, as well if you're using a kernel that has a different extra modules folder.

@androide7461 and @montefuscolo -- thanks - now it is connected

Now i just have to figure out how to use it.

thanks again

@TecMunky: Try the solution from @montefuscolo. It worked for me. There are no errors what so ever now. Thanks @montefuscolo!

@tomvigl - I got the same error @androide7461 got when executing the "modprobe" command -- "modprobe: FATAL: Module v4l2loopback_dc not found in directory /lib/modules/5.5.13-1-MANJARO"

what now?

@android7461 - that is not what I meant - but I don't use yay. I simply deleted the entire droidcam directory, then extracted the snapshot again, edited the build file, then executed the make command.

Also, I did not get any errors during installation. My error came when I executed the modprobe command.

I had to modify this line on Manjaro Linux, running kernel 5.4

MODPATH="/usr/lib/modules/extramodules-$(uname -r | sed 's/.[0-9]\+-[0-9]\+//')"

@TecMunky I deleted my cache with "yay -Sc" and reinstalled with "yay --editmenu -S droidcam". I hope this was the way you meant. But now I get this error when I'm installing it: "insmod: ERROR: could not insert module /lib/modules/5.5.13-1-MANJARO/extramodules/v4l2loopback_dc.ko.gz: Unknown symbol in module error: command failed to execute correctly" It's installed nonetheless. But when I try to open it I get the same error as TecMunky. Then I checked if the module is loaded like tomvigl said with: "lsmod | grep v4l2loopback_dc". It returns nothing, so I guess it's not loaded. After that I write: "modprobe v4l2loopback_dc" and get this error: "modprobe: FATAL: Module v4l2loopback_dc not found in directory /lib/modules/5.5.13-1-MANJARO". Which makes kind of sense because I think it wasn't installed properly.

You have to check if the module is loaded: lsmod | grep v4l2loopback_dc If not - add the module with: modprobe v4l2loopback_dc

tomvigl: That worked for me. -- THANKS

androide7461: first you have to delete the extracted directory, then extract the snapshot again --> THEN modify line 58 to use "readlink -f"

But now, I need to learn how to use it ...

When I start the droidcam client I get a popup saying "Device not found (/dev/video[0-]). Did you install it?"

Check if the right linux-header is installed: pamac search linux-headers | grep $(uname -r | cut -d "-" -f 1,2)

If there is nothing like [Installed] you have to install it: pamac install linux[0-9][0-9]-headers

@AwesomeHaircut I had already earlier mentioned that I downgraded to the old LTS kernel. Still nothing of the mentioned here works. Still am waiting on a CLEAR answer about how and where to add this makepkg -si

Exact location and short tut, please, and I am okay trying it again.

I changed my pkgbuild as you said but it didn't work for me :(

I also had problems installing droidcam on Manjaro with kernel 5.5.13-1-MANJARO! The problem was that extramodules is a symlink. The Solution is to resolve the symlink with "readlink -f".

Change the build file in line 58: MODPATH=$(readlink -f "/usr/lib/modules/$(uname -r | sed 's/.[0-9]+-[0-9]+//')/extramodules")

I have looked at all the comments about my issue (I think), but am still having a problem installing this package. I get the following message:

error: failed to commit transaction (conflicting files) droidcam: /usr/lib/modules/5.5.13-1-MANJARO/extramodules exists in filesystem (owned by linux55)

So I downloaded the snapshot and tried "makepkg -si" - and got the exact same error

Maybe this wiki page can get you out of your confusion @Saka2u1u https://wiki.archlinux.org/index.php/Makepkg

Again, no need for workarounds or manual installs. Whatever you normally use for installing things should work now.

Actually I think no one even says where and how to use the makepkg -si with which code... Nothing works, enough time wasted. Removed.-

I was indeed missing the linux-headers package.

I went ahead and installed 5.5, and the 5.5 headers (I don't know why it wasn't installed along with it), and that seems to make thing work wonders again.

Completely different issue. Thanks a ton for the help.

It's about both; it should match exactly. It looks like you're booting from a different kernel version than the kernel headers you have installed. If you install linux 5.5 make sure you also install the linux5.5-headers. Otherwise make sure you're booting with the correct kernel and have linux_version-headers corresponding to it. In your grub or syslinux boot file, you have to make sure you're booting the correct kernel. This wiki link might help? https://wiki.manjaro.org/index.php/Manjaro_Kernels

Cool, the output of the those for me is:

pacman -Qi linux-headers|grep Version Version : 5.4.28-1

uname -r 5.4.24-1-MANJARO

Should uname -r not have the "-MANJARO" part in it perhaps, or is it just about the version number? I still have the same issue after a reboot, I can update to 5.5 fwiw.

From what i've seen, there's nothing specific to manjaro from keeping this from working. No need for downloading a snapshot or anything else anymore :-] it should all be working as normal @Arndroid You probably have to reboot. Make sure your system is up to date, specifically your kernel and kernel-headers, and try again. You want to make sure uname -r matches pacman -Qi linux-headers|grep Version

@AwesomeHaircut thank you for the support.

I downloaded the snapshot and run the makepkg -si command: ==> Validating source files with md5sums... droidcam.desktop ... Passed icon2.png ... Passed ==> Validating source_x86_64 files with md5sums... droidcam.tar.bz2 ... Passed ==> Extracting sources... ==> Starting prepare()... ==> Starting build()... make -C /lib/modules/uname -r/build M=pwd make[1]: warning: jobserver unavailable: using -j1.

As you can see, I do use Manjaro, is this the cause of the issue I have? It does seems very similar to the issues others have recently mentioned.

If I can provide further info, please let me know.

Ah nice work @AwesomeHaircut.

fixed?! You guys let me know please :]

I don't mean edit the PKGBUILD @Shaka2u1u I mean instead of running yay -S pkgname or octopi -S pkgname You download a snapshot of this aur. (On the top right of this page, above "Search Wiki" and below "View PKGBUILD / View Changes") Once you have the files, cd into the directory with the PKGBUILD in it and then run makepkg -si

These instructions are generalized for anyone else that might need them, since you already have it downloaded :]

Hello, even after commit 4586966807ed i'm getting the /dev/video[0-9] error and the cat complaint. My system is up to date with linux-headers version matching kernel version. I installed the package using makepkg -si. Any clue of what's going on? I also have the optional dependencies installed and up to date.

Cheers, M.

After a kernelupdate I had to reinstall this, to get everything working again. Is there a way around that?

Hello,

It says that the extramodules folder already exists in the system. Git says in the cache folder that master is 4586966807ed.

Not sure why it's trying to take ownership on the folder ?

Thanks, it's working now.
When installing, i'm still getting the

cat: /usr/lib/modules/extramodules-5.5-2/version: No such file or directory

Any idea what that is about?

Great that helps a lot, I will push a change for the update since that's what seems to be happening :-)

@AwesomeHaircut my system is up to date, and i have the same version of linux-headers as the kernel.
Weirdly enough, when i'm trying to use makepks -si instead of yay, i've got:

==> Validating source_x86_64 files with md5sums...    
    droidcam.tar.bz2 ... FAILED    
==> ERROR: One or more files did not pass the validity check!    

thanks for your help.

What do you use for installing this package? @Bitts311

@itiel Make sure you have linux headers for your current system installed and have your system up to date. The PKGBUILD will be looking for headers for whatever kernel your system is running and that may need a reboot.

@everyone running Manjaro or using a aur helper Installing this using makepkg -si and see how far you get :-]

I have been trying to install droidcam for 2 days without success.
When installing, i get cat: /usr/lib/modules/extramodules-5.5-2/version: No such file or directory, but the installation continues. I cant figure out where is this cat comes from, and my kernel is

$ uname -r
$ 5.5.9-arch1-2

when i'm trying to start droidcam, i have the error:

Device not found (/dev/video[0-9]).
Did you install it?

I've tried everything that i can think of, but without success. can anybody help me?

@Shaka2u1u I was able to build this package fine on Arch just now. I think this is a Manjaro specific issue, and I am having trouble with realizing what might cause it.

No idea why it gives this problem still, cause I already rolled back to kerne 4.19

@LevitatingRein, the package have logically splited parts: kernel module and binary utility progrom. DKMS-module will be update module every time for the all installed kernels (when install or update kerenel). Also note droidcam in this packages is simply precompiled binary so more correctly call it droidcam-bin.

@artemklevtsov, that's an interesting idea. I have never worked with shared packages before. What are the benefits to your solution?

Finally my fixes have been pushed, if anyone still faces issues please let me know.

@AwesomeHairbut, I made a disown request for the package a while back, it was now finally accepted, but I wasn't made co-maintainer apparently. If you could make me maintainer that'd be great, then I can finally push my fixes to this repo.

I don't understand what's going on with the ownership of this package but I'm reclaiming for now. I'll be sure to update it within the next 24 hours now that I have time to so again :-)

@artemklevtsov

Ever since kernel 5.4 this version of the module has stopped working. I have created a droidcam-dkms-git version of the package that install the tools from the 6.7.5 version, but the module code is pulled in from git. When upstream makes a new release, I'll update this one.

@LevitatingRein thanks it works for me.

I suggest to split the package to droidcam-bin and droidcam-dkms parts.

Why xanmod kernel, and 4.9, and 4.14, and 3.16 ? This is madness !

for those who have this error Device not found (/dev/video[0-9]). change MODPATH in the pkgbuild file, like this : MODPATH="/usr/lib/modules/$(uname -r | sed 's/.[0-9]+-[0-9]+//')/extramodules"

it will work after reboot.

Same issue, Error: Device not found (/dev/video[0-9]). I installed and loaded v4l2loopback-dkms, it didn't help.

Updated :-)

Actual md5 for the x64 package: "9507c0b738f427c5f1dde7b2a364fdfb"

@abdulhakeem: Just replace the "md5sums_x86_64" value in your build files. Assuming your running 64bit ofc, otherwise manually download the 332bit one, run md5sum on it and replace the value for i686 accordingly.

@fadysghatas how to update the checksums so the package will install?

New checksums for 32 and 64 versions are : (x32) 928f2e9eefee5e076eec16b1f7c12992

(x64) 984b068a87f28d6326ca1e064f4fc584

these should replace the first value in md5sums and md5sums_x86_64 respectively.

New checksums for 32 and 64 versions are : 32: 928f2e9eefee5e076eec16b1f7c12992 64: 984b068a87f28d6326ca1e064f4fc584

these should replace the first value in md5sums and md5sums_x86_64 respectively.

Its out of date, alright. How to compile it??

Here's updated PKGBUILD and install script. I have no permission to this repo so I'm posting it here. Hope it helps!

https://recolic.net/tmp/PKGBUILD https://recolic.net/tmp/droidcam.install

The module doesn't compile under linux 5.0. I have fixed the problem here, and you may use this patch directly.

Please update soon because ArchLinux kernel already goes 5.0.x

Instead of the following line in the PKGBUILD: MODPATH="/usr/lib/modules/extramodules-$(uname -r | sed 's/.[0-9]+-[0-9]+//')"

This should be used instead, to allow for the module installation to work properly: MODPATH="/usr/lib/modules/extramodules-$(uname -r | sed 's/.*-//g')"

The droidcam.install file also needs modifying here: _extramodules="extramodules-$(uname -r | cut -f-2 -d'.')-$(uname -r|sed -e 's/.*-//g')"

To be replaced instead with: _extramodules="extramodules-$(uname -r | sed 's/.*-//g')"

This should get the proper name without including the version.

as for kernel 4.18, the PKGBUILD needs a slight change to fix error: cat: /usr/lib/modules/extramodules-4.18-zen/version: No such file or directory that file is currently in /usr/lib/modules/extramodules-zen/

So version numbers got dropped from folder name

Ah great! I actually have to do a few things more than that but it should be straightforward thanks!

Issue has been resolved on this project's Git: https://github.com/aramg/droidcam/issues/7. Just need a package update for the new md5sums.

EbKeth can you try adding v4l2loopback-dkms as a dependecy? make sure you install https://aur.archlinux.org/packages/v4l2loopback-dkms/first.

Package will not compile on linux 4.15, included v4l2loopback module has not been updated to the new kernal timer API.
