vorbis-tools/libvorbis is apparently not 64-bit clean
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=149295
Using vorbis-tools-1.0.1-4, libvorbis-1.1.0-1 on Fedora Core 3, doing the following:
- Rip some CDs to flac with sound-juicer
- On a x86_64, run 'oggenc -q6' on the flac files to make oggs
- Listen to them
The x86_64 ogg file has pops, scratches, etc. If you encode the same flac file on a 32-bit box, it sounds fine.
http://people.redhat.com/notting/oggtest/
has a source flac file, and the ogg files from running 'oggenc -q6' on it (32.ogg is on i686, 64.ogg is on x86_64.)
Oddly, both 32.ogg and 64.ogg show the audio artifacts when played with ogg123 on x86_64.
Initially assigning against libvorbisenc. Feel free to move it.
