Rockbox on my ClipV2 cannot play back (at least certain) MPEG-4 audio files. When these files are encountered in the playlist, playback skips over them. In that instant I can see that the track metadata is displayed correctly in the WPS, and it is also correct in the database.
Sometimes skipping over the “broken” tracks even hangs playback totally, with a subsequent non-mp4 file stuck at 0:00, requiring a stop + resume.
Sometimes, I see a “codec error” splash for a couple of milliseconds when the files are skipped.
I have tested various revisions between SVN current and r28308 (a pre-3.7 revision), and all show the same behavior.
Here are two files I've encountered this problem with: (warning, large podcast tracks)
These files seem to play fine in the simulator.
However, one really strange thing I've encountered is that the simulator pauses playback after playing back the file for a few minutes. I can then manually unpause to resume playback of the track. This may be a related or totally unrelated problem.
