​https://trac.ffmpeg.org/ticket/2459
Same problem as this ticket, but I get another error too (the maxband 30 one).

Note, these problems also happens with mpc 475 and ffmpeg-git. Sorry if I wasn't supposed to open a new ticket for this.

Please reopen this ticket if it is reproducible with current FFmpeg git head and once you uploaded a sample.

As you can see, it happens with musepack-tools 475 and ffmpeg-git, and the duration is still wrong.

musepack sample

[Carl Eugen Hoyos]

Regression since 11a1033c / 8f2aa89a
The regression is also reproducible with the sample from ticket #2459 but the difference is much smaller there and the report is different (and also reproducible with this sample).
