Hi, Regarding to my previous question, I think I have found out from oggenc source code that the correct way to initialize encoding is: vorbis_encode_init_vbr (or vorbis_encode_setup_managed for cbr etc.) vorbis_encode_ctl (to turn off or use avg bitrate management) vorbis_encode_setup_init By this way, there is no problem with encoded stream. However, there is no documentation of the three

Hello, I am trying to implement a realtime encoding then streaming solution using the vorbis codec (would be wrapped in a "7F" type for minimal framing overhead) for sending audio over a low bit rate wireless link. since we need a constant bittrate (i.e. constant packet size) for this solution we want to run the alg in constant bitrate mode; for evaluation of the codec I followed the

Hi, I am trying to encode PCM to OGG based on example code in OggVorbis SDK Win 1.0. There is no problem with "vorbis_encode_init_vbr(&vi, 1, 44100, 0.4f);" setting. However, using "vorbis_encode_init(&vi, 1, 44100, 96000, 96000, 96000);" setting gives such a warning by ogginfo: "Warning: EOS not set on stream 1" I have modified ogginfo to display exact

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 )

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, 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, A short mail to let you know that the MSVC project files aren't OK compared to the Makefiles. Indeed they include the vorbisenc part (vorbisenc.c file, and vorbis_encode_* function names in the .def file) inside the vorbis library, and they also point to a non-existant file (bitbuffer.h) Here is a patch to fix this, in case you are interested (patch made on the win32 directory using

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

Jan, Here's a hacky patch to add a few commandline options for setting comment header fields in ffmpeg2theora. It's a bit big because I virtualized the global info struct in theorautils.c. In retrospect that probably wasn't necessary, but I think it's cleaner anyway. I didn't test it because I couldn't compile ffmpeg2theora, but modulo bugs it should support

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

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, 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.

Hi, I am testing the encoder example and I have a question about it... How can I encode a mono file in 22050 and 44100? I've changed the init values to: ret=vorbis_encode_init_vbr(&vi,1,22050,.5) ; and in the loop: // uninterleave samples for(i=0;i<bytes/2;i++) { buffer[0][i]=((readbuffer[i*2+1]<<8)|(0x00ff&(int)readbuffer[i*2]))/32768.f; } ..

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.

I have just downloaded the vorbis sdk for windows, for researching purposes. I have compiled the example 'encoder_example.c' just to start, and it compiles, but I got a error in the following line just at the beginning: vorbis_encode_init(&vi,2,44100, -1, 128000, -1); The error is more or less: The instruction at '0xaddresss' referenced memory at '0xaddress'. The

More information about the error below: I have downloaded the source and I got the same problem, but now I know in which exact line the error is. Inside the vorbisenc.c, we have the following function: tatic void codec_setup_partialcopy(codec_setup_info *ci, codec_setup_info *cs){ int i; memcpy(ci,cs,sizeof(codec_setup_info)); /* to get the flat numbers */ /* codebooks */

Hello: I think that I got a linking problem but I don't know how to fix it. This is the error code form make: cc grabando_pcm.o encodear_vorbis.o -o mi_servidor -lasound -lvorbis -logg encodear_vorbis.o(.text+0x42): En la funci?n `inicializar_vorbis': : undefined reference to `vorbis_encode_init_vbr' collect2: ld devolvi? el estado de salida 1 make: *** [mi_servidor] Error 1

I'm having trouble tracking down why it leaks, but below is an example program which shows--using valgrind--that vorbis_info_clear() leaks memory if called before vorbis_dsp_clear(), but not if called after vorbis_dsp_clear(). Just compile and run under valgrind, using the -l switch to the example program to trigger a leak. Tested under OS X 10.7 and Ubuntu 12.04. This may be by design, or
