FFMpeg generate test.mp4 without audio track. It complains to increase analyzeduration, I increase it to 20000000, still the same.

Plays fine with vlc.

comment:4 follow-up: Changed 6 years ago by cehoyos

Workaround would be to use -acodec aac but the output file is completely out-of-sync.

Do you know what created the sample?

comment:5 in reply to: ↑ 4 Changed 6 years ago by zoominla

Replying to cehoyos:
I don't know, I get it from internet.

comment:6 follow-up: Changed 6 years ago by cehoyos

Does any other application except vlc play the file?

comment:7 in reply to: ↑ 6 Changed 6 years ago by zoominla

Replying to cehoyos:
MediaInfo? parses the a/v info correctly.
Media Player Classic also plays it fine.

Your patch works, thanks for your nice work!
