> or = ffmpeg-4.1.3 ebuilds show WARNING: Building with deprecated library libavresample in configure phase. # Mandatory configuration myconf=( --enable-avfilter --enable-avresample --disable-stripping https://github.com/FFmpeg/FFmpeg/commit/c29038f3041a4080342b2e333c1967d136749c0f "lavr: deprecate the entire library Deprecate the entire library. Merged years ago to provide compatibility with Libav, it remained unmaintained by the FFmpeg project and duplicated functionality provided by libswresample. In order to improve consistency and reduce attack surface, as well as to ease burden on maintainers, it has been deprecated. Users of this library are asked to migrate to libswresample, which, as well as providing more functionality, is faster and has higher accuracy." Please remove --enable-avresample (defaults to "no") or add an USE flag for it. libswresample is built by default. If there are any packages still depending on lavr then we can make a tracker bug of this after the change.
do we have any package still needing this ?
(In reply to Alexis Ballier from comment #1) > do we have any package still needing this ? media-video/transcode-1.1.7-r4 https://bugs.gentoo.org/show_bug.cgi?id=722296 was the only one that needed a patch when I rebuilt the installed packages depending on ffmpeg. Let's find it out.
After some months of testing with disabled avresample and with now fixed transcode bug I see no problems on my system. Please go ahead and remove the config option setting.
alsa-plugins still seems to use it at least

media-video/webcamoid[ffmpeg] uses it as well.
If there is any interest I can develop a patch series to put libavresample under a USE flag and make alsa-plugins[ffmpeg] and webcamoid[ffmpeg] dependent on it.

ffmpeg-4.4.2.ebuild and ffmpeg-4.2.4-r2.ebuild are the last ebuilds with --enable-avresample The 2 PRs in gentoo about avresample are closed now. ffmpeg-5.0.1.ebuild and ffmpeg-9999.ebuild don't have it anymore. Let's keep this bug open as reminder for people who use the old versions and to avoid duplicates. Can be closed when the 2 affected versions are removed from tree.
Just a note, also media-libs/libopenshot-0.3.2-r1 searched for it but as it also finds libswresample as mentioend in this thread it is probably working as expected against media-video/ffmpeg-6.1.1-r1: -- Checking for module 'libavcodec' -- Found libavcodec, version 60.31.102 -- Checking for module 'libavformat' -- Found libavformat, version 60.16.100 -- Checking for module 'libavutil' -- Found libavutil, version 58.29.100 -- Checking for module 'libswscale' -- Found libswscale, version 7.5.100 -- Checking for module 'libswresample' -- Found libswresample, version 4.12.100 -- Checking for module 'libavresample' -- Package 'libavresample', required by 'virtual:world', not found -- Found FFmpeg: /usr/lib64/libavcodec.so;/usr/lib64/libavformat.so;/usr/lib64/libavutil.so;/usr/lib64/libswscale.so;/usr/lib64/libswresample.so (found version "6.1.1") found components: avcodec avformat avutil swscale swresample missing components: avresample

Would've wanted to drop USE=nvenc due to its dependency on old nv-codec-headers but rather mask it not to have to update revdeps that depend on nvenc over this. Hopefully not overlooked anything relevant, spent less time on this than ffmpeg-7 and "downgrading" an ebuild is awkward. Ultimately this version is going to be short lived, there is almost nothing left (that we package) that requires it.
