corrupted data in mp3s

Postby tygern8r » Wed Dec 15, 2010 4:25 pm

I have a handful of songs that were doing this, stopping at the exact same spot (all CBR mp3s). I tried removing them, renaming them, updating the index - all to no avail. The same mp3s play fine in every other player: VLC, iTunes, Amarok. I figured my mp3s must be corrupted somehow and Subsonic is just pickier than other players, or the other players have some kind of error correction ability.

Since I'm at work on a Mac, I found MP3 Scan and Repair, a free utility for Mac. I scanned the problem mp3s and the results were that each of them was corrupted. Some had "garbage at end of file" warnings, others said "wrong number of MPEG data bytes specified in Xing header" and so on. Once the files were repaired and replaced on the server, I restarted Subsonic and all the songs play - no skipping, no stopping.

great work tygern8r!

now we just need to figure out why Subsonic on PC is this "picky" when no other media players are, including Subsonic on my Android.

help!

in the meantime, does anyone know an PC equivalent for “MP3 Scan and Repair”?

You could try to check and fix all files with mp3val.

MP3Val did it!!! Good work everyone, and thanks for sticking with it.

The MP3s were corrupt- I've had a few different errors so far, two of them being:

1) "MPEG stream error, resynchronized successfully"
2) "Wrong number of MPEG frames specified in Xing header"

The good news is that Subsonic web is the ONLY thing that sees this as a problem. All other media players handle it fine, including Subsonic for Android, MP3 players, phones, and computer-based players. Some might disagree, but I call that a problem with Subsonic, NOT a problem with the MP3s themselves.

Just please be careful when scanning and repairing- I would only recommend doing this to albums that are definitely having this "ending early" problem, since it physically changes the files.

Another thing to note- by default, it creates a backup of each MP3 it repairs in the same folder, so keep that in mind.
