What bitrate are you using? Perhaps you set it to a value in kb/s instead of b/s. -------------- next part -------------- An

There shouldn't have been between 1.1-beta and release. I guess you can't tell us which argument is bad because the win32 binary is stipped. Have you tried compiling it yourself? -r

Hi, I just checked in a fix for the bug you reported. Let me know if it works.

I just recently found that opus_multistream_encode_float is returning -1 (OPUS_BAD_ARG) with the libopus 1.1 build but works just fine with the libopus 1.0.1 and libopus 1.1-beta builds. I tried using opus_multistream_encoder_create and opus_multistream_surround_encoder_create. Tried with coupled and uncoupled quadraphonic and uncoupled stereo encodes. I'm dynamically loading the libopus

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

Just in case my quotation causeed misunderstnaing... Forget about what I quoted before. Probably, by CBR, Monty meant ABR since CBR is stupidly patented and this is the reason why Vorbis has no CBR option. If you know this, it cannot be a problem but I see there is a question asking what is ABR in the mailing list. >On Thu 28 Jun 2001, 23:27:41 PDT, Monty (xiphmont@xiph.org)Wrote: >then

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, 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

Hi, I try to use the video tag to post videos on my blog I'm using ffmeg2theora to transcode videos in theora Resolution of 320x240 pixels and constant bitrate (CBR) of ~400 kbps seems to be ok for publishing on my blog. I've read that CBR is a better choice than VBR for web publishing regarding the way TCP/IP works. ("In TCP it takes a while for a connection to increase its

Finally got it to compile and attach the MSVC debugger. It fails at the following: if ((!st->variable_duration && 400*frame_size != st->Fs && 200*frame_size != st->Fs && 100*frame_size != st->Fs && 50*frame_size != st->Fs && 25*frame_size != st->Fs && 50*frame_size != 3*st->Fs) || (400*frame_size <

Hi guys, I'm using Opus for speech in wide-band mode (sampling rate 16000) and 20ms frames with signal type set to SIGNAL_VOICE. I have a few questions here: 1. When I choose VBR mode, the codec seems to choose the bitrate on its own. However, that seems to be an issue on mobile devices. In some cases, when I configure the bitrate to say 20kbps, I see that the outgoing codec bitrate at

fwiw, there are definitely applications that would use Vorbis but can't until there is a _strict_ CBR mode. Meaning, architecturally the datarate simply cannot exceed X no matter what happens to the quality. Send silence if you have to, but limit the datarate. -dbm -------------- next part -------------- A non-text attachment was scrubbed... Name: winmail.dat Type: application/ms-tnef

Hi, Is there any difference between decoding of CBR or VBR streams in realtime in terms of CPU usage/cost? Are sample rates other than 44100Hz supported by Vorbis officially ? If it is supported, is it efficient to use them or is Vorbis specifically (or at the moment) optimized for 44100Hz ? Thanks in advance. --- Mete BALCI Senior Game Programmer Momentum DMT Istanbul, TURKEY

Hi All; If someone used speex and has experience with its settings, then who can help to explain the following: 1) When it is recommended to use VBR (vbr => true)? 2) If there relation between setting the vbr => true and the abr value (for example to be 0 or 1 or 10) and the relation between this value and abr (true / false). 3) Any relation between the quality value and the abr value?
