2148,crash reading M3U8 audio files playlist,saste,,"Summary of the bug:
How to reproduce:
{{{
ffmpeg -f lavfi -i ""aevalsrc=cos(2*PI*t)*sin(2*PI*(440+4*t)*t)::d=20"" -f segment -segment_time 10 -map 0 -strict -2 -codec:a aac -segment_list list.m3u8 out-%03d.mp4
}}}

{{{-f lavfi}}} was used to generate the input, but any audio file will do.

The individual mp4 files generated are playable.

Then if you try to read the generated file with ffmpeg -i list.m3u8 it crashes (same with ffprobe/ffplay):
