Wait for upstream to commit the patch.

It still is in state "New" along with ~30000 other patches
https://patchwork.ffmpeg.org/project/ffmpeg/list/?state=1
and I would feel bad being the guy asking for an ETA ;)

Same answer ;)

Same answer ;)

Added by buildroot commit f30bd1eb69c44793485e9f013249d020e3e19fc3 to "add 
-latomic to pkg-config files". A patch addressing the same problem was 
committed to ffmpeg 5.1 several months later: https://code.ffmpeg.org/
FFmpeg/FFmpeg/commit/2f0a214a6202516b4dda2bb22b6b3ac20e465d6d

I will check whether we still need patch 0004.

Upstream asked me to do that:

Use it forever... FFmpeg decided to remove libpostproc and created a 
plugin mechanism so it can still be used:
https://github.com/xbmc/xbmc/commit/
587f3a6e936d487552d002bd63a0e4ff74bee433

LibreELEC carries the patch as well:
https://github.com/LibreELEC/LibreELEC.tv/tree/master/packages/multimedia/
ffmpeg/patches/postproc

Kodi needs it for vaapi-based hardware deinterlacing
https://github.com/xbmc/xbmc/pull/5253#issuecomment-53122885
applied to content like many 1080i DVB-S channels.

Regards, Bernd
