But when streaming, IMHO it is

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

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.

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, 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(),

Hey I am playing with a LOT of threads right now, and I want to know if the threads all need their own little vorbis encoders running in them or what exactly is threadsafe in vorbis? So here are the functions that would be called from many threads of with buffer = vorbis_analysis_buffer( &m_vorbisDsp, 4*DATA_CHUNK_SIZE ); vorbis_analysis_wrote( &m_vorbisDsp, dataLength/dataSize );

Hi, I have recently implemented encoding/decoding to/from OggVorbis in my app, with the code being based upon the Libvorbisenc sample code supplied with the SDK. It all works very well indeed (encoding from a PCM file, then playback), except that no matter the length of the source PCM file, the last (approx) 4 seconds of audio is always missing from the Ogg file. I am trying to find some

I've been trying to piece my way through the encoder_example.c program to better understand how to encode files as ogg/vorbis. I'm stuck on two sections of the code. This is the first /* uninterleave samples */ for(i=0;i<bytes/4;i++){ buffer[0][i]=((readbuffer[i*4+1]<<8)| (0x00ff&(int)readbuffer[i*4]))/32768.f;

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 All, I m having a strange problem with the Ogg-Vorbis writting code. The code I m using to write is skipping some samples at the end of the file. For example I m converting the 10000 sample .wav file ( 441000 sample rate , 16 bit depth , stereo ) to ogg format. But while reading the ogg file I only find 5824 samples in the ogg file. Can any one suggest what could be wrong in the code. Is

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?

I am trying to install vorbis-tools 1.0.1 onto my mac os 10.3.5 I installed the relevant libraries through fink (http://fink.sourceforge.net) - libao2, libvorbis, libogg my configure command was this: ./configure -with-ogg=/sw --with-ao=/sw --without-flac --without-speex I received no errors from configure except to let me know that oggenc would not have flac support and that ogg123 would

Now when I run 'make' I get the following error(s):

It looks like the Mac .exp files were not updated for RC3. The following diff corrects that problem. The CodeWarrior project files also have not been updated. They are in 5.3 format which is quite old. Would anybody object if I submitted updates to them in CodeWarrior Pro 6 format? That's the oldest version I have readily available. If someone else has 5.3 and wants to do it, you need to

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
