Windows ACM Driver
during the last weeks I was playing around with Windows ACM codecs. These drivers allow the use of audio compression algorithms in Microsoft Windows Apps like Goldwave or the Microsoft Audio Tools (e.g. for streaming). At the moment this code is in a very early stage, only some houskeeping functionality is finished at the moment. But I think it should be possible to implement this thing without

How can I get the precise play time of the ogg vorbis file?
Hi all, ? I have a?question about the ogg vorbis decoder.?As far as I know, there are?three?vorbis headers -- ID, Comment and Codebook. And in?ID header, I can get the sample rate, maximum bitrate, nominal bitrate and minimum bitrate. Now, I want to get the play time of the file, so I use the file length to divide the nominal bitrate, and get the play time, but it is always shorter than the real

Getting a GUI to work with Vorbis code
I am trying to create a Graphical User Interface for a Vorbis Player under MS Visual C++ 6.0 I was initially trting to use the code from decoder_example.c but I keep getting linker errors. I have set up my project as told to by James Boer on this mailing list. This is as follows: This document was prepared from an email received from James Boer on the Ogg Vorbis mailing list. It gives a

q re vorbis packetizing in ogg stream
>From looking at the code, it looks like the first vorbis header in a stream is always placed in its own page. It also looks like maybe the audio data (i.e., the stuff after the headers) is maybe also supposed to begin on a new page. Is this part of the spec? I notice, though, that the second and third headers share a page, at least in one .ogg I looked at. It seems like it would be easier

Vorbis I spec errata: single entry codebooks
The following has been committed to the Vorbis I spec as of r19445: Errata 20150226: Single entry codebooks A ?single-entry codebook? is a codebook with one active codeword entry. A single-entry codebook may be either a fully populated codebook with only one declared entry, or a sparse codebook with only one entry marked used. The Vorbis I spec provides no means to specify a codeword length of

How Ogg mappings translate into the codecs parameter in Ogg media types
Hello list, We have recently introduced the codecs (optional) parameter on the Ogg media types for easier identification of encapsulated codecs in conditions were it's not feasable to examine the streams directly. I received a comment from the IESG that we should have some sort of list to describe how Ogg mapping strings translate to codec parameter strings, so I went ahead and compiled a

Raw/general purpose Ogg based container format?
(crossposted to theora-dev, since I thought some folks there might be interested) Hi all, Does anyone know of a ogg based container format that would be appropriate for holding raw AV data? I'm specifically interested in PCM audio, and uncompressed YV12 and RGB32 video. Basically looking to use it as a lightweight tool interchange format, generally muxed by mencoder and read/modified by

Update on Vorbis RTP I-D
Hi all, I'm in the final stages of putting a new Vorbis RTP draft together, the new sections are below. There are a number of open questions: 1.) At present there is a 16 bit length field for the codebooks. As they are spec'd as being unbound in length, but typically around 15K, are there situations where they may be greater than 64KB? The size limit can be extended to 2MB as there

ACM using TrueSpeech codec (acmStreamOpen())
Hi all, I and a few others are trying to implement Yahoo voice chat under Linux. Since Yahoo uses the TrueSpeech codec, we are trying to load the TrueSpeech DLL directly under Linux. mplayer can play TrueSpeech files already, and it appears that it contains portions of Wine code to do so. But mplayer cannot create TrueSpeech files as far as I know. We have ripped the relevant code out
