Summary of the bug:
The audio codec s302m produce in combination with loudnorm filter an
error:
{{{
[s302m @ 00000275a32cba00] number of samples in frame too big
Audio encoding failed
}}}
How to reproduce:
{{{
% ffmpeg -f lavfi -i testsrc=size=1280x720:rate=25:duration=5 -f lavfi -i
sine=frequency=1000:duration=5 -af
"loudnorm=I=-23.0:TP=-1.5:LRA=11.0:dual_mono=true" -ac 2 -c:a s302m
-strict -2 -f null -
}}}
Uncut output:
