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(),

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

Sounds like a sound driver issue. Might want to try the SMP version of OSS (www.opensound.com). Do other sound apps work OK? -bg > On Sat, 20 Oct 2001, Akos Maroy wrote: > > /me cries, bummer deal. > Yes, running as root. > The load was in the 'teens as I remember, I looked @ that too. > One CPU was like 15% and the other 11%, something like that. > 2.2.19ext3 #2 SMP,

Hello, I'm not quite sure if this is the right list for my questions, please excuse if it isn't. 1. While using vorbislib (Win2K/Borland C++ Builder 5), I'm getting reproducible floating point exceptions at lots of sample rate/bit rate combinations. For example, the original encoder_example.c, with just the initialization line changed to

Hi, I'm experimenting with managed mode encoding with specifying maximum bitrate. I call: vorbis_encode_init( &vorbisInfo, 2, 44100, -1, 96000, 96000); to initialize the encoding. To my surprise, it seems the maxbitrate value of 96000 doesn't have an effect, the bitrate of the

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

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

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?

Yes, everything else has always worked great. I'm lisrening to EpiphanyRadio sream via xmms right now. *8^) I've tried the commercial OSS stuffs long ago, haven't had need of them.

For those of you not of the commit mailing list, I wanted to point out that monty has checked the fixed-point 'tremor' vorbis decoder into xiph.org cvs, under the usual (free) xiph license. This was developed for use in embedded devices, so if you've been waiting for an interger-only (no fpu) implementation, you might want to give it a try. The code is in the 'Tremor' cvs

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 )

Hi again! I have some other suggestions/modifications. 1. Bitrate scaling by frequency in vorbis_encode_init: bpch=(long)((float)nominal_bitrate/(float)channels*44100.0f/(float)rate); With this modification, if we use -b128 at 22khz files, the OGG file will be 128kbit/s, not 64kbit/s ... 2. Probable quality bug: I tested some floating point constants (recalculated them (see below) and encoded

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

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 --- >8

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
