Reason for closing:  Accepted

The first file is probably corrupted. VLC simply refuses to play it and seems unable to parse its header (gives wrong track length). ffmpeg does play the file however. Looking at the metadata its got a huge PNG file stuck in the Vorbis tags as a “comment” that none of my programs can understand. You could try removing that and see if that fixes your file.

The Ogg layer tries to read the entire comment packet into memory, which fails due to the large embedded album art (Foobar2000 can display it, by the way).

yeah, the failure playing files with a huge comment packet is known, we could skip that packet entirely to avoid this problem IIUC since we don’t use the metadata in the codec anyway.

Here’s a patch that hacks around the huge comment packet problem and should let such files play fine, it works for the one such file i have. It would be interesting to hear if it also works for others.
