Patch for bitrate information in ogginfo
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.

encoding bitrates, different machines...
...vs. AMD Athlon), would it? There's no
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

VBR encoding in ogglame? (BOUNCE vorbis@xiph.org: Non-member submission from [Jesse Hammons <jessehammons) (fwd)
...xample what would 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?
Thanks,

ogginfo integrity tests
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...

new vorbisenc behaviour
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
