vorbis_encode_init() bitrate arguments - offtopic
Hi,
It's a bit offtopic for this list, but you might be able to help. For
libvorbis rc3, what is the correct bitrate parametrization for the call
vorbis_encode_init()?
For rc2, it worked calling it the following way:
vorbis_encode_init( &vorbisInfo,
2, // two channels
44100, // 44.1kHz

vorbis bitrates - offtopic
Hi,
I'm experimenting with IceCast2, using DarkIce to generate the stream. I
have found some peculiarities with the vorbis bitrates.
In DarkIce, I call vorbis_encode_init() with about the following values:
vorbis_encode_init( &vorbisInfo, 2, 44100, 96, 96, 96);
which by all reasons should generate a 96 kb/s stream, as all
max_bitrate, nominal_bitrate and min_bitrate are set to 96.

vbr / cbr / abr API calls
Hi,
Maybe this is documented somewhere, if so, please send me a link to the
documentation.
My question is: how to set up different (VBR, CBR, ABR) modes when
calling the Ogg Vorbis API?
Currently I do:
CBR:
ret = vorbis_encode_setup_managed( &vorbisInfo,
getInChannel(),
getOutSampleRate(),

Adding RC3 support to GoldWave
Here are some minor things I noticed when updating the vorbis module
for GoldWave:
Bitwise.c, line 175 and 207
Warning: Negative unsigned value
ret=-1UL;
Info.c, line 385
Warning: Unreachable code
break;
vorbisfile.c, line 1407
Warning: Call to function with no prototype
int host_endian = host_is_big_endian();
fix: add 'void' to line 1339:
static int host_is_big_endian( void )

Currently min and max are ignored by the library, since bounded bitrates

Thanks for the tip. I added the calls, and it works now.

Low bitrates
Hi,
I want to encode audio at very low bitrates.
however, vorbis_encode_init() does not allow me to set bitrates below 32kbps. How can i
set 24kbps?
Thanks,

Possible channel coupling bug in encoder
I'm not sure that this is not my fault, but here it goes:
I'm trying to encode a 22 kHz Mono stream. I started with the encoder
example and made it take dynamic channels etc. This is how I init it:
vorbis_info_init(&VorbisInfo);
vorbis_encode_init(&VorbisInfo, 1, 22050, -1, 128000, -1);
then I get a crash in:

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

Fwd: Re: Asterisk T.38 Pass-Through doesn't work
Hi!
I have exactly the same problem on asterisk 1.8.22.0 and also on separate
11.2.1 when sending fax to PSTN.
Tryed with spa-3102, spa-2102, Patton Smartnode 4634, and Zoiper softphone.
SpanDsp also works without any problem on my box.
As I remember it was a bug in 1.8.1.x that the a=T38MaxBitRate paramater
was sent as "maxBitRate". Without capital "M".

dynamicly loading libvorbisenc on Mac OSX
Hi,
I'm trying to load the vorbis libs dynamicly on Mac OS X.
I've got success for libogg, libvorbis and libvorbisfile. But
libvorbisenc drives me crazy.
The function "vorbis_encode_init" seems not to be in there if I am
using "NSLookupSymbolInImage". But
the tools "otool" and "nm" tell me that the function is declared.
Does anyone know, what I

vorbis.m4 macro glitch
Hi,
I discovered a little error in vorbis.m4. The source for the test
compile uses vorbis_encode_init() but does not include vorbisenc.h.
This causes the test to fail when AC_LANG(C++) is used in my
configure.ac script.
For now my work-around is to surround the Ogg Vorbis tests with
AC_LANG_PUSH(C) ... AC_LANG_POP(C) calls, but it should probably be fixed.
Thanks,
Davy

A few questions about libvorbis from a newbie
First off, I don't even know if this is the right place to ask these kind
of questions, but I haven't been able to find answers anywhere else, so
1. I have found that "pcmTotal * vorbisInfo->channels * 2" gives the
uncompressed size of every ogg vorbis file I have used. What is a more
robust way of getting the full uncompressed file size?
2. How do I read a certain amount of

error in "encoder_example.c"
Hi,
Why do I get an error message when i'm running the
"encoder_example.c" which is included in the SDK?
The error occurs then the 44 bits are read and the
vorbis_info struct is initiated (i.e. when the
vorbis_encode_init(&vi,2,44100, -1, 128000, -1) -
funcion is called. I also tried to read the data from
a 16 bits 44,1 KHz stereo PCM - wave file but recived
the same error.

vorbis API calls
Hi devs,
I am developing winLAME, a frontend for LAME, and it also supports Ogg
Vorbis decoding and encoding.
I've got a question about the new API function
vorbis_encode_init_vbr(). Do I have to call vorbis_encode_init()
before to set the bitrate(s)? And what is a good default value for the
"base_quality" parameter?
I read on the mailing list that ABR use in Ogg Vorbis is not so

ice2 CVS build problems under Solaris 7
Hi:
If you want to use icecast
2 for streaming vorbis audio then don't get it
from the CVS repository at icecast.org. That's ancient developer stuff in
there. Instead get it from the xiph.org CVS repository (see
http://www.xiph.org/cvs.html which I see now lists the icecast stuff
