[Rhythmbox-devel] FLAC files produced by rhythmbox are very malformed



Hi all,


A few months back this bug started, while there was a huge gvfs + udisks change over causing even nautilus to not be able to read CD's. I've held off till now on reaching out until that died down a bit however the bug still persists. Any track I rip within Rhythmbox produces malformed FLACs (with various brand new CDs, and across different optical drives).


Most notably is that this is a problem solely with FLAC's ripped from Rhythmbox and SoundJuicer. Cdparanoia rips wav's just fine, and those can be converted to FLACs that work just fine.


The symptoms of the bug are fairly troubling. The metadata container cannot be updated, and therefore the files have literally no metadata in Rhythmbox, nor can it be set from any program. Running flac -d on the file fails and produces the following error: "ERROR while decoding metadata                     state = FLAC__STREAM_DECODER_END_OF_STREAM" and running metaflac from command line produces (for a random sample file) 258599 lines of what looks like hexdump output. A metaflac on SoundJuicer's looks like normal output but also fails to decode. If you "flac -Fd" on either Rhythmbox or SoundJuicer's FLAC file and try to convert it back, it reports errors as well about expected EOF's, so it looks like something's not quite right.


The back-end looks like it's calling to a gnome library to rip these tracks, but I'm not too familiar with the Rhythmbox codebase to say for sure. Can someone comment on how these files are produced? I'd like to see this bug fixed, and am willing to help but could use somewhere to start.


Thanks,

Nick
