...m to handle end-of-stream very well. I would like to be able to rewind. First I tried the brute force method: if (videoStream.eof()) { ogg_stream_clear (&theoraStreamState); theora_clear (&theoraState); theora_comment_clear (&theoraComment); theora_info_clear (&theoraInfo); ogg_sync_clear (&oggSyncState); videoStream.clear(); videoStream.close(); init_the_movie_like_it_was_inited_the_first_time(); } But I got a crash when trying to re-initialize: theora_decode_init (&theoraState, &theoraInfo); Specifically this line in quant.c...

...height was the height of the inner picture region... and height was the height of the outer frame. Then upon readnig the spec... where it calls the outer part the frame and the inner part the picture region... i assumed i'd made a mistake and that frame_width is actually >= width in the theorainfo structure... ie frame_width is the size of the frame and width is the size of the picture inside the frame. So now i'm completely confused. Could someone please clarify if the following is correct... theorainfo.frame_width = width of the inner picture region theorainfo.width = width of th...

hi all, i'm trying to code a tool to get some images from a ogg/theora file .... so basically i need to get a frame and convert to rgb ... and here is my question (sorry, i'm newbe here) ... how to convert a yuv_buffer to a rgb matrix ? i tryied diferent ways but my mistakes are bassically cause i don't understant how yuv_buffer structure works ... anybody can help? thanks a lot.

I'm trying to encode a picture from my webcam using the theora codec. The final "product" must encode a frame, send it over the network and decode it on "the other side". For now, it must only work locally so we don't care about the transmission. This is what I've understood till now: I have a char * buffer from the camera RG24,I convert it to YCbCr 4:4:4, I

Hello everyone, I'm currently developing an adaptive videoconferencing application based on Ekiga which uses TFRC as a congestion control mechanism to adapt the video encoding rate according to the quality of the network experienced. My goal was to use the open-source Theora codec for video transmission. Unfortunately, it seemed that Theora 1.0 did not properly implement any correct CBR mode.
