Hello, I'm new to this list, and pretty much also to the codec universe. In a computer game I'm working on, there is an 3D TV-screen onto which I project the frames of a movie. The movie is of course stored as theora, no audio as it's not needed yet. I have it working so far, extracting a frame and uploading it to the graphics card when the scene is drawn. The example file

Hey there I had implemented Speex encoding nicely in an application I was working on when I realized that I needed to change the API. I changed it, and the change somehow broke the speex encoding section of the code. The program writes SPX headers that other programs can read, but does not generate the rest of the file correctly. I have been through the guide "programming with

Hi there, I haven't been on this list until now, so I wasn't aware of this problem until last night ;-) - sorry for that. I am working on a patch for oggCut for that issue (looks good actually but I would like to do some testing befor I can release a patch.) Normal players are not effected by the page time misordering, so I took this issue as "minor". The reason for the

I'm having trouble getting libvorbis to cut the beginning of a bitstream when I instruct it to do so with granulepos. I have constructed a file which I believe should have its beginning truncated. I have attached it to this mail. Here is a picture of what the bitstream looks like, as output by a python program that uses pyogg/pyvorbis to read the stream and print a representation:

Hello! My name is Lars Quentmeier and I'm trying to write a theora-player. Video is already showing up, but unfortunately I can't get my Vorbis-Decoder to work correctly. Could you perhaps help me? My decoding function looks like this: int VorbisDecoder::getAudioData(char* audiobuf, int fragsize){ // single audio fragment audio buffering bool audiobufReady = false; int size=0; int

Hi all, I am happy, to announce the first (Alpha) release of the oggToolspp. The basis of the command line tools is a small, but hopefully growing library for manipulating ogg streams (mainly video streams) written in c++. The aim of this library is, to provide easy access methods to ogg pages, ogg packets and the video-frames and audio-samples in the end. The command line tools are actually

Hi, (I was discussing this with Adam earlier today, and he has also mailed vorbis at xiph.org about this issue in March). This sounds like it needs a new tool specifically for fixing broken Ogg files. Suggestions so far (tried by Adam, or suggested to him in email/IRC): * oggz-sort, hogg sort These rewrite the file, sorting the pages by presentation time. This usually fixes muxing problems,

...ng the next vorbis or theora packet(s) and reading from the physical stream (+ split the streams to a vorbis or theora logical stream) if more data is needed. This works for theora streams with low dynamic data rates but not for my test streams, where from time to time a single keyframe needs 20-30 OggPages of data. Normally you can handle this by prebuffering some already decoded audio sample buffers or video frames but even with buffers of some megabyte this is in practise no solution because the audio decoder has to wait till theora is ready with reading/preparing/decoding it's pages. And bef...

I have over 1,000 ogg vorbis files that are no longer playable or editable. I believe the main cause was a MediaMonkey plugin that automatically fetched album art and added it to the header. The plugin itself just uses the generic MediaMonkey metadata facility, but something happened -- perhaps when the album art bitmap image was too large -- that caused the files to no longer work.

I'm trying to generate the 4-byte crc code for the comment tag in an ogg file.. Can anyone point me to a function where this is done? Unfortunately, I can't use the lib directly, and the crc function I did find in it doesn't seem to do what I want directly. But, that might mean I'm not feeding it the right chunk of data. Any details would be helpful - yes I read the docs and I
