I did git bisect and I was at
Bisecting: 2 revisions left to test after this
which was almost there.
But I couldn’t reach the final point because some functions and variables were changed from this suggested commit

avplay: do not use AVStream.codec for decoding
AVStream.codec is now deprecated. Allocate a separate codec context
for example av_get_default_channel_layout and av_frame_get_pkt_duration.
But as you see there were only 2 revisions and this might be the one or very close for that makes this happen.
Would it be helpful?
