Broken with mlt 6.8.0. Nothing we can do but wait for upstream...

RubenKelevra commented on 2018-05-18 07:19

Doesn't start at all, completely broken. Please fix!

On commandline:


modules path: /usr/share/pyshared/Flowblade MLT not found, exiting... ERROR: /usr/lib/ version `MLTPP_6.8.0' not found (required by /usr/lib/python2.7/

oberon2007 commented on 2018-04-17 18:38

Thank you @koA7 . Added sdl_image as depends.

koA7 commented on 2018-04-17 18:30

I had to install another dependency to make this work. At the start it complained about: mlt_repository_init: failed to dlopen /usr/lib/mlt/ ( cannot open shared object file: No such file or directory) which led to a segfault. After installing the package sdl_image I was able to start the program.

oberon2007 commented on 2018-02-17 18:16

I've patched the script to use a static launch path. Makes sense since the package installs it to that location anyway ;)

bebR commented on 2018-02-17 17:07

@oberon2007: the @test0 solution did the trick for me.

oberon2007 commented on 2018-02-11 20:44

@bebR Weird. No issue for me in i3 with dmenu or when executing .desktop launcher or the /usr/bin/flowblade script. Try if the edit suggested by @test0 solves it for you. If so we can include the edit in the package. For me both versions work.

bebR commented on 2018-02-11 20:25

The desktop entry does not work for me. Flowblade runs flawlessly when executed from a terminal. But the desktop shortcut does nothing. I use i3 and rofi.

test0 commented on 2018-02-09 15:04

@pzmarzly: edit your launch script ( sudo nano /bin/flowblade)

hash this line

launch_dir = os.path.dirname(os.path.abspath(sys.argv[0]))

and add this line under it

launch_dir = "/usr/bin"

oberon2007 commented on 2018-02-07 11:58

Make sure you have regular mlt installed. Currently the app will not work with mlt-git !

@pzmarzly not sure what the problem is for you. I can launch it with $ flowblade just fine.

pzmarzly commented on 2018-01-01 14:24

Program doesn't want to start from PATH. Using absolute path helps.

Clips imported into Flowblade do not play in the compositor window. Instead, any imported clips spawn a separate, new X window from the Flowblade interface when the Flowblade "play" button or spacebar is clicked for a selected clip. The separate window is entitled MLT. When I installed Flowblade via yaourt, it was noted that MLT was "in conflict" with MLT-git (required by the yaourt Flowblade build). I was prompted to remove MLT in favor of MLT-git, which I did. Anyone else experiencing this apparent bug?

deimidis commented on 2017-10-21 14:58

Thanks @oberon2007 So I will need to wait until they solved.

oberon2007 commented on 2017-10-21 09:20

It's currently a known issue:

oberon2007 commented on 2017-10-21 09:18

Yes, @deimidis, there seems to be a new issue. Will investigate.

oberon2007 commented on 2017-10-21 09:15

@spsf64, mlt-git provides mlt. You can install both flowblade and shotcut without problem.

deimidis commented on 2017-10-21 03:16

I had this problem after install (i replaced mlt with mlt-git)

spsf64 commented on 2017-10-09 22:45

Is there any workaround to use mlt?
"mlt-git" conflicts with shotcut.
Thanks for maintaining this package

oberon2007 commented on 2017-07-12 14:39

I've switched dependency to mlt-git. Working for me.

uranio-235 commented on 2017-07-11 17:58

if do not start after an upgrade, roll back you mlt package

I wonder, if compliling again wil solve the problem

oberon2007 commented on 2017-06-20 11:39

@kozaki I cannot reproduce the issue. Flowblade runs fine with regular mlt for me and I also just rebuilt it again to verify. My pkgvers are identical to yours.
Have you actually built it against these latest versions?
I'm reluctant to use a git pkg for the stable version unless absolutely necessary. It makes incompatabilities more unpredictable in general...

kozaki commented on 2017-06-20 11:16

Segfault when launched with your PKGBUILD mlt (6.4.1-6). Installed mlt-git from AUR and it opens/loads a video file. Installed versions as follow:

frei0r-plugins 1.6.1-2
gavl 1.4.0-2
gmic 2.0.0-2
gtkglext 1.2.0-10
hdf5 1.10.0_patch1-2
mlt 6.4.1-6 # --> mlt-git r4482.1496039392.66545cb5-1
mlt-python-bindings 6.4.1-6
movit 1.5.1-1
opencv 3.2.0-4
pangox-compat 0.0.2+2+gedb9e09-2
sox 14.4.2-1
swh-plugins 0.4.15-6
xine-lib 1.2.8-2
flowblade 1.12.2-1

Thank you for maintaining this PKGBUILD!

oberon2007 commented on 2017-02-25 16:29

Thanks. Added mlt-git for now.

markon commented on 2017-02-25 15:48

Successfully compiled 1.10-2 but got segfault in libmlt 6.4.1 so i installed mlt-git(aur). Now it works (at least flowblade starts and i can load hd sequences)

oberon2007 commented on 2017-01-27 16:26

Thanks @spsf64. I removed python2-rsvg which is deprecated. librsvg (a depends of gtk3 anyway) seems to be enough. Compiling and launching fine now for me.

spsf64 commented on 2017-01-27 15:22

1.10-1 does not compile, requires python2-rsvg (not found)

oberon2007 commented on 2016-12-13 14:02

update to 1.10. Dependencies sox and movit added.

oberon2007 commented on 2016-12-07 14:28

package fixed and updataed to v1.8

Your package is broken with a certain dependency like flowblade-git

Launch script dir: /usr/sbin
Running from filesystem...
MLT found, version: 6.2.0
Failed to import module to launch Flowblade!

sxe commented on 2016-03-04 09:06

I agree. Done

thirtythreeforty commented on 2016-03-04 01:58

As of v1.6.0, I think there should be an optional dependency on the gmic package, because the Tools > G'MIC Effects menu complains about the lack of /usr/bin/gmic.

dizzy commented on 2015-10-27 05:40

OK, I'm probably missing something here but:
1. this package doesn't work at all for me, I get this error at startup (after I edit "flowblade" to actually display the backtrace instead of hiding it and displaying only the text error)
Traceback (most recent call last):

2. I don't really understand what's up with the custom download link. I changed the PKGBUILD file (in an effort to make sure that I'm running the right version here trying to fix error #1) in 5 minutes to use the official repository location for downloading the code:

NOTE: that changes the package version from 1.2.0 to 1.2, which makes sense because there is no flowblade 1.2.0, there is only a 1.2 (i.e. the flowblade releases do not use a x.y.z format but a x.y one)

Anyway... any idea about my error at #1? Googling a bit it seems that "" is GTK+3 API and as far as I can tell I only have GTK+2 on this system and this package dependecies doesn't seem to require GTK+3. Then again, the FlowBlade official changelog says that the move to GTK+3 happened after 1.2 (a big point of the upcoming 1.4 release) so no idea what's going on here.

Thanks for any help!

sxe commented on 2015-07-22 09:37

ok, updated again, back to dropbox.

cube95 commented on 2015-05-07 16:25

I think the releases are these.

You can also go with tags, instead of branches. I really don't know the difference, i didn't tested.

sxe commented on 2015-05-07 08:28

I have fixed the Upstream URL but i will keep the source code location for this package how it is.

I made a new package to respect the naming convention: and furthermore gets the code from git repository.

Until i know if there will be releases in tar.gz form i will keep this package.
If git will be the only way to get it in the future this package will be marked obsolete.

Thx for the info Anonymous.

Anonymous comment on 2015-05-06 19:32

new repository

sxe commented on 2015-04-24 06:25

Fixed, thx IwfY.

IwfY commented on 2015-04-23 20:25

python2-dbus is missing as a dependency.

osc commented on 2015-03-22 18:29

0.18 is out.

sxe commented on 2015-03-10 12:24


Updated it. I have no idea why it suddenly works but i will not complain. ;)

fho commented on 2015-03-10 11:08

PKGBUILD for current (0.16) version can be found here:

Gorbag commented on 2015-01-03 16:59

That is the same link that osc has posted, only without "?dl=1". I saw the link of flowblade-0.14.0 in the PKGBUILD is although a dropbox file without the sign above and so i tried it. Then i changed the "pkgver" and the "source=" link in the PGKBUILD to the new version.

sxe commented on 2015-01-03 12:49

Hi Gorbag,
where did you find that link?

Gorbag commented on 2015-01-03 11:19

I used this link '' in the PGKBUILD and it download the file and build the package without problems.

sxe commented on 2014-12-05 14:58

I already tried that link, but it does not work.
The PKGBUILD always downloads the html of that page.

osc commented on 2014-12-05 14:23

here is the new address for this version:

you can find the instructions here:

sxe commented on 2014-12-04 20:58

thx, i already tried to update the PKGBUILD. Sadly it cannot download the latest dropbox file. I will keep trying.

osc commented on 2014-12-04 18:51

version 0.16 is out.

orschiro commented on 2014-08-27 09:26


Welcome. Thanks for updating the package straight away!

sxe commented on 2014-08-27 07:48

Well, i guess we have to switch then.
I have added the new version.

Thanks for keeping me up to date.

orschiro commented on 2014-08-27 06:25


Finally received a response:


"The reason 0.14 is distributed via Dropbox is that Google Code no longer allows adding files for download."

So what to do about it now?

sxe commented on 2014-06-22 19:58


orschiro commented on 2014-06-22 18:59


I asked for the reasons to host on Dropbox in their tracker:

sxe commented on 2014-06-22 08:42

Well, there is no package on the official google code page right now. The only package available is hosted on dropbox what looks kind of fishy to me. I will wait until an official package is availabe.


orschiro commented on 2014-06-22 07:25

NEW: Flowblade Movie Editor 0.14 has been released on June 18, 2014

Glinx commented on 2014-01-17 07:32

Thank you boenki, makepkg -si worked.

boenki commented on 2014-01-16 21:01

*Make sure base-devel is installed: pacman -S base-devel
*makepkg -si will build, install dependencies and install the programm.
*Consult the wiki for more information:

Glinx commented on 2014-01-16 17:58

Make a pkg file to install with, i.e. sudo pacman -U flowblade.pkg.tar.xz

sxe commented on 2014-01-16 17:08

What are you trying to do?

Glinx commented on 2014-01-16 16:30

Im not getting a pkg file to install with makepkg -S pkgbuild. What am I missing?

fvsc commented on 2013-10-01 09:23

It works now.
I removed it and installed it back and O wonder it works.

fvsc commented on 2013-09-29 10:05

I have the same problem, both versions crash at starup with segmentation fault.

I use a 64 bit system.

sxe commented on 2013-09-16 18:24

Nop, works for me. Try to remove the config directory.

osc commented on 2013-09-16 17:14

both this and the hg versions crash at start up.

Mentat commented on 2013-06-16 18:17

sxe, great!
just switch, install it and it seem to works like a charm.
I'll give you feedback if necessary.
Thank you very much for having make this build.

sxe commented on 2013-06-16 15:49

Hi Mental,
i made one:

Check it out and let me know if it works.


Mentat commented on 2013-06-16 13:28

sxe, thanks for have packaging this great app!
Can we hope a PKGBUILD with last hg version?
The project is very active.
I try to make one myself but fail at the moment.

jsteel commented on 2013-04-23 21:05

python2-imaging is a dependency (otherwise ERROR: No module named PIL).

sxe commented on 2013-04-14 08:14

thanks, fixed

samuellittley commented on 2012-06-17 17:44

NB. I've edited the patch in my previous commit to put all of the tabs inside scrollwindows, so nothing overlaps any more.

samuellittley commented on 2012-06-17 16:48

If you want to use it without the screen size requirement, try applying the patch below to the source before running You might need to alter the patch so that the file paths are correct, I ran it from inside $srcdir. I've managed to make flowblade open on my 1366x768 machine, looks to be working alright except for a little bit of overlap on the render tab. Unfortunately I have no video files to fully test with.

sxe commented on 2012-06-12 10:43

I have no idea, you should ask this to the developer i think.

lobisquit commented on 2012-06-12 10:26

The program gives me this error: "Minimum screen dimensions for this application are 1152 x 864. Your screen dimensions are 1366 x 768"
Is there any way to solve this?
