Summary of the bug:
Trying to transcode some video file fails in the latest ffmpeg master with
this message:
`Too many packets buffered for output stream 0:1.`
It works in 3.2.4 and stopped working in 3.3.0. Using git bisect I could
identify this commit as the first bad commit:
af1761f7b5b1b72197dc40934953b775c2d951cc
How to reproduce:
{{{
% ffmpeg -y -i "./too_many_packets_buffered_example.mp4" -f mp4 out.mp4
