Copy-protected discID confusion

Hello!
May I please direct your attention to the comments on http://musicbrainz.org/show/edit/?editid=11206312 The summary is this is a disc with: * tracks 1–10 normal tracks, one song per track. * track 11 has two songs on it (kind of like a “hidden” song, although AFAIK the song is listed on the packaging, and even the release title implies its existence). * it appears there is a 12th “data” track containing some kind of copy protection. * two different applications generate the same TOC and discid (I think SoundJuicer uses MB's library): SoundJuicer: http://musicbrainz.org/bare/cdlookup.html?id=SZIe2XCEedGBIu8SL253aq.0YOw-&toc=1+12+202682+150+12107+29055+46162+59357+80830+97030+111532+128037+144465+160550+214082&tracks=12 Picard: http://musicbrainz.org/bare/cdlookup.html?id=SZIe2XCEedGBIu8SL253aq.0YOw-&tracks=12&toc=1+12+202682+150+12107+29055+46162+59357+80830+97030+111532+128037+144465+160550+214082&tport=8000 * however, SoundJuicer (a CD-ripping Linux application) seems to get confused by the copy protection, and reports thirteen tracks to the user (although the discid-lookup string it generates asks for 12). When ripping it generates thirteen files, the last two of which are copies of track 1. * strangely enough, the page opened by the lookup URL does not offer to search for a release to attach the discid to. I've no idea what that means. I'm tempted to remove track 13 from the edit mentioned above, mark the 12th as “[copy protection]”, and put the two song names in track 11. However, I don't know if that will allow us to add the discid, nor what will happen to confused apps like SoundJuicer. Also, I thought devs might like to take a look at it before I make any changes. What do you guys think? -- Bogdan Butnaru _______________________________________________ MusicBrainz-devel mailing list MusicBrainz-devel@... http://lists.musicbrainz.org/mailman/listinfo/musicbrainz-devel |

As was pointed out by nikki in the edit, this appears to be a bug in
libdiscid. I'd agree, you should remove the 13-track release—it's an artifact of a bug in a library, not a valid TOC track per MB disc ID specifications. Could you maybe try to use cdparanoia proper, and see what it does with the "extra" tracks? SoundJuicer—if I recall correctly—uses Gstreamer which may in turn use cdparanoia. It may be that Gstreamer sources or filters or extraction libraries are resulting in strange extraction.

Hi Paul,
I only encountered the edit while voting, I don't own the disc in question. If you think it's useful you might try contacting the original editor for more diagnostics. -- Bogdan Butnaru On Tue, Sep 29, 2009 at 5:12 PM, Paul C.
