Bug 222097 – media-sound/amarok-1.4.8 has problems with flac

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Albert Zeyer 2008-05-14 16:14:39 UTC]

It plays them correct and you can pause/resume, but you canoot jump to a random position. When you do that, the scrollbar just jumps back and the audio stays muted for a while (though it's still playing at the same position it was before). After a few seconds, the audio is unmuted again, though still at the old position.

That occurs on all Amarok versions I have tested so far and on all systems I have.

First of all, it has very little to do with Amarok as this is an issue of xine-lib.

Second, this happens because your FLAC files have no seektable. I'd be ready to bet you created them through audiocd:/ IO-Slave, it's known to generate FLAC files without seek table.

Using the libFLAC demuxer/decoder in xine-lib (flac USE flag in xine-lib) would probably let you seek. On the other hand you can make the files seekable again without rebuilding xine-lib by generating a seektable through use of metaflac(1) command.

HTH,
Diego

[Comment 3 Albert Zeyer 2008-05-14 17:30:12 UTC]

flac USE-flag was already set.

I also haven't seen any seekable flac so far. But I also have none of them created by myself. The flac I was recently listening too are the ones published by Nine Inch Nails.

metaflac helped though.

Thanks

[Comment 4 Albert Zeyer 2008-05-14 17:36:02 UTC]

How can I get the ability to seek also without such a seektable? This should be possible somehow.

[Comment 5 Diego Elio Pettenò (RETIRED) 2008-05-14 17:40:41 UTC]

I'm not going to implement it in xine as the seektable is there for a reason. Strange that the flac USE flag didn't get it to work though, it usually does, at least for the files created through the audiocd:/ kioslave.
