This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.
Comment 3 Dominik 'Rathann' Mierzejewski 2026-05-21 12:17:45 UTC 
This is fixed in 7.1.2 and later.
Comment 4 Dominik 'Rathann' Mierzejewski 2026-05-22 10:39:07 UTC 
Actually fixed in 8.0: https://github.com/FFmpeg/FFmpeg/commit/c08d300481b8ebb846cd43a473988fdbc6793d1b
and backported to 7.1.3: https://github.com/FFmpeg/FFmpeg/commit/baee5f5e2751b61572abe23a8f8a0042d27c89e6

Although, to me it's dubious that it made sense to backport the fix to older branches when the code calls ff_flush_packet_queue(s) a few lines later unconditionally (unlike in 8.0+).

Opened upstream issue: https://code.ffmpeg.org/FFmpeg/FFmpeg/issues/23201

I'm going to close this because it looks like <8.0 is not affected.
