I had the same issue as mentioned here:
"with the latest version (7.1-5) I get the following build error:
libavdevice/v4l2.c: In function ‘device_open’:
libavdevice/v4l2.c:141:17: error: assignment to ‘int (*)(int, long unsigned int, ...)’ from incompatible pointer type ‘int (*)(int, int, ...)’ [-Wincompatible-pointer-types]
141 | s->ioctl_f = prefix ## ioctl;
does anybody know how to solve this?"
I had some issues creating a patch file (but that's on me) so I manually changed the offending file
steps to manually fix
yay -G ffmpeg-obs

Please, this package follow Arch Linux
ffmpegpackage version (not the staging or the testing one).Don't put
ffmpeg-obsout-of-date if both packages are on the same version. If you do, you might be ignored in the future.tytan652 commented on 2021-12-17 15:32 (UTC)
OBS Project actually patch FFmpeg to fix some issues and also add RIST support starting from 27.2.
So I created this package, a ffmpeg package that ensure that you have those.
I really wanted to not do this but some fixes are needed, so I did my best to add those "feature-set options".
They allow you to build ffmpeg with feature-set based on other ffmpeg packages from AUR.
Read the PKGBUILD for more information about them.
