search for: bitrate_lower

With this patch, ogginfo will display bitrate information (upper/lower/nominal/average bitrate). It is patched against today's CVS code (main branch). I am also working on true VBR support in oggenc (the user can specify the minimum & maximum bitrate) and will send a patch when it's done. <HR NOSHADE> <UL> <LI>application/x-gzip attachment: ogginfo-diff.gz

...CPU specific optimisations yet, e.g. selecting 3dnow instructions for the latter. Does 129 and 124kbit look about right for a -b setting, does one get that kind of range? Here I'm missing that "encoding parameters" tag. Hehe. Both have: bitrate_upper=none bitrate_nominal=128031 bitrate_lower=none Thanks, Hugo --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

...I need to do to see what a 44.1Khz mono track sounds like at 50kbits/sec (instead of 68). I've had a look at the source code, but can't really see where a datarate control would fit in. As far as I can tell from a recent CVS snapshot, none of the files are looking at the bitrate_upper and bitrate_lower variables in a meaningful way. Is anyone else looking at this?

After accidentally ogginfo-ing a WAV file, I'm wondering if there's any reason I shouldn't commit my fix that breaks out of the current file test if header integrity fails. Is there any case where the header integrity will fail but there is still any useful information to get out of the stream? I don't think so... -- Kenneth Arnold <ken@arnoldnet.net> - "Know

Just got around to compiling RC3 under beos and came across an anomaly when using managed bitrates. I haven't changed the code for the beos encoder but I now get double the bitrates so vorbis_encode_init(&vi,mediaFormat.u.raw_audio.channel_count,(long)mediaFormat.u.raw_audio.frame_rate , -1, 128000, -1); now gives me vorbis files that average around 325 - 350. Is this now the correct
