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

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,

Thanks for the reply, But that still tries to read for itself from libogg... i need to be able to feed data only... it can never try and read for itself. That code is still trying to control the data flow. Basicly i need to operate like this. SetupCodec when i have data to give to the codec FeedDataToCodec(data) //Receive a bunch of callbacks somewhere returning me pcm data //Codec

Dear theora developer community, currently I'm working on a simple Theora player for Windows. But the code in the player_example.c seems not to have the performance of other implementations like the Direct Show filters by illuminate. In the example player, all important things are done in one thread: decoding the next vorbis or theora packet(s) and reading from the physical stream (+ split

quite some speed improvement indeed. attached the updated patch to apply to svn/trunk. j -------------- next part -------------- A non-text attachment was scrubbed...
