I'm getting an OBS segfault with this module installed. Any ideas?

ThePooN commented on 2023-07-08 20:57 (UTC)

@adoa The mentioned patch is no longer needed, I simply removed it. Thanks for the report!

@Freso I have applied your Qt 6 fix, thanks! Regarding submodules handling, I don't see any benefit over handling them this way. Re-building here doesn't redownload/extract anything, I can only see maintenance burden 🤔

This package no longer builds correctly. It errors with

==> Starting prepare()...
error: patch failed: source/encoders/encoder-ffmpeg.cpp:1045
error: source/encoders/encoder-ffmpeg.cpp: patch does not apply
error: source/encoders/handlers/handler.cpp: No such file or directory

I made a couple of changes in the -unstable PKGBUILD that you might want to adopt for this one, notably: (Qt 6) (better git submodule handling)

If you have the git repository for this package cloned locally, you can add as a remote and you should be able to git merge or git cherry-pick to adopt the changes. The commits for obs-streamfx-git are already part of the history of obs-streamfx-unstable.

@ThePooN ok thanks for update build successful, it works again with no problems yet

ThePooN commented on 2023-03-29 15:56 (UTC)

Apologies for the delay.

I tried getting it to work with FFmpeg 4.4 instead of FFmpeg 6 as that's what OBS and StreamFX target. Unfortunately, while it built fine, I couldn't go past a muxing error when starting my test recordings.

I instead opted for a patch similar to the one proposed by @iq2luc. Tested and works fine on my end.

Hello @Bomlex, @TiagoSinH,

unfortunately I don't have the time and interest to maintain such a package, I use obs+streamfx very rarely. Personally, I compile obs with streamfx support built-in, this is also what the developer recommends anyway ( Still, I had to apply the mentioned patch for it to work.

I will upload for you a pre-built Archlinux package, but I'm a bit worried about that because I'm afraid I'll be breaking some policies (for streamfx) with this approach since the official Archlinux package also doesn't come with streamfx built-in. The author of streamfx puts a lot of effort into developing this great software (

Anyway, here is the link: <removed-2023-04-22 20:44:00> If someone tells me I'm breaking some policy, I will remove it.

Edit: Download link removed, package issues fixed by the maintainer (thanks @ThePooN for the quick resolution).

Bomlex commented on 2023-03-18 10:41 (UTC)

can't build, think because of ffmpeg. as some have already written here.

Yes, I would also be interested in how I do it with cmake or patch. what @iq2luc says. because the maintainer probably doesn't care about all that.

TiagoSinH commented on 2023-03-15 22:55 (UTC)

sorry, im a newbie. how do I configure the cmake variables?

Hi adoa, compilation fails because in handler.cpp@12 and encoder-ffmpeg.cpp@1048 it tries to use a constant (AV_CODEC_CAP_INTRA_ONLY) which is not available anymore in ffmpeg 6, it is only available in 4. So there are two options: 1. configure the corresponding CMAKE variables to use ffmpeg4.4 instead of ffmpeg (e.g. FFMPEG_xxx_INCLUDE_DIR=/usr/include/ffmpeg4.4 and FFMPEG_xxx_LIBRARY=/usr/lib64/ffmpeg4.4/, or 2. apply the following patch:
