Hello, I am currently developing a ogg vorbis decoding module for use in winlame (a LAME frontend), and I have some questions: To do a decoder I used most code in decoder_example.c, but I think there is something missing. I would be glad if someone could look at this code: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/winlame/winlame/source/winlame/wlOggVorbisDecoderModule.cpp and

Hi vorbis-devs, I use the Ogg Vorbis libraries built from the win32sdk in winlame. Since the rc2 DLL's are not functioning, I compiled them by myself. The apparent reason is that some data arrays like _residue_P were not shared among DLLs. I looked at the code, and found that IMHO dirty hack in vorbis/win32/src/shmmap*.h that maps the data arrays. Why not placing the data arrays in

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(),

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! In the SDK documentation it is written: "base_quality Desired quality level from 0.0 to 1.0" But, i can give less than 0 parameter too. Why? Although, if i give greater than 0.9, encoding is halt with "floating point division by zero" message. Why? Thank you for your reply, crc --------------------------------- Do you Yahoo!?

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 )

We knew the TCP-BBR developed by google and try to optimize the transport efficiency of TCP, I’m wondering will this be beneficial if we put tinc in TCP mode plus the TCP-BBR?

I understand the concern of uncertain for TCP-over-TCP by BBR, as the BBR is natively designed to optimize TCP, instead of TCP-over-TCP, but could you articulate a bit more about the beneficial of “sending host when there is a UDP tinc tunnel” in the middle”? > On 30 Sep 2017, at 11:23 AM, Ryan Mounce <ryan at mounce.com.au> wrote: > > I'm not aware that BBR claims nor

Hi, I'm a newbie to audio compression. And I have several question about ogg. 1. How many bits a vorbis sample take ? does the sample size 16 bits ? like the mp3 ? CMIIW 2. How do a decoder recognize how many sample it takes in a second ? does it related with the code books ? 4. Does vorbis use VBR ? 3. What is function of the Windows ? and what is the output of the windows ? Thanks

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

Hi, my system (solaris b77) was physically destroyed and i loosed data saved in a zpool mirror. The only thing left is a dettached vdev from the pool. I''m aware that uberblock is gone and that i can''t import the pool. But i still hope their is a way or a tool (like tct http://www.porcupine.org/forensics/) i can go too recover at least partially some data) thanks in advance for

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 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 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 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?

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

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'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.

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, 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
