I am continuing to use the version compiled with ffmpeg7 and have
found no bugs or other problems. Even the efficiency of playback and
some rendering are comparable with the previous version. All OK, for
me.
This is good news! I am a bit worried about ff_ audio plugins, especially acting on few audio tracks at once. It will be amazing if you try few of them on say mono/stereo sources to see if result still same as with ffmpeg 6.1
