Some files cause the log file size to explode

Bug report

Describe the bug

Remember me complaining about the size of the log file? Yeah, i thought it was because of the database update. Turns out that ffmpeg is freaking the fuck out about some (playable) m4a files and dumping the whole debug output to the mpd log, to the point that after half a minute of database update i had a 360 mb log.

Expected Behavior

Not sure. Maybe i did screw up with the file conversion, but i didn't expect mpd to use ffmpeg with such a verbose output. Report possible problems, sure, not dump maybe gb to file.

Actual Behavior

Dunno.

Version

Music Player Daemon 0.21.4 (0.21.4)

.... and then apparently it keeps going for the whole size of the m4a file, repeat.
