When trying to create ogg/vorbis files with oggenc and specifying a maximum bitrate of more than 172 kbps, a file with very little data is created. After invoking oggenc with "-q 5 -m 96 -M 255" on a Wave file, ogginfo tells the following about the output file: Processing file "track01.cdda.ogg"... New logical stream (#1, serial: 17e57f59): type vorbis Vorbis headers parsed for stream 1, information follows... Version: 0 Vendor: Xiph.Org libVorbis I 20040629 Channels: 2 Rate: 44100 Nominal bitrate: 192.000000 kb/s Upper bitrate: 0.173000 kb/s Lower bitrate: 0.096000 kb/s Vorbis stream 1: Total data length: 54416 bytes Playback length: 8m:26s Average bitrate: 0.859494 kbps Logical stream 1 ended Reproducible: Always Steps to Reproduce: Encode a file with 'oggenc -M 173' or higher values of M Actual Results: Nonsense file output Expected Results: Create an ogg/vorbis file with actually data in it
After some experimentig, libvorbis reveals to be responsible. Emerging libvorbis 1.0.1-r2 is a workaround.
What version was the broken one? libvorbis-1.0.1-r2 and libvorbis-1.1.0 are the only versions I can see in the portage tree currently. So if this was a bug in older vendor version, I suggest that this bug is marked as FIXED.
Yes, please always report versions and provide 'emerge --info'
Created attachment 45397 [details] emerge --info libvorbis-1.1.0 is the affected version
Have you reported this upstream?
bumping back to sound@
Can you test this out with libvorbis 1.1.0 with new local use flag "aotuv"? The aoTuV use flag adds the latest patch from aoTuV which has some (tiny) chance of having an effect on this.
The aoTuV patches did not solve the problem. I am lucky to currently sit at an Opteron Workstation with Gentoo at work. This machine also produces the bug.
forward bug upstream to the author?
This bug is supposedly fixed in libvorbis-1.1.1.
Unable to reproduce the bug on libvorbis 1.1.1; marking FIXED.
