Playback does also work nicely for me. But if I try to convert the audio
stream in e.g. AAC, I see different errors with the provided samples.
Sample from comment 24 gives me:
[ac4 @ 0x7fef1480a200] substream audio data overread: 1153
Error while decoding stream #0:0: Invalid data found when processing input
