The cause is that theora_decode_init() expects a theora_info structure which was previously initialized by passing actual bitstream data through theora_decode_header(), as doc...

...issue is that CodingMethod is equal to 5 (CODE_GOLDENFRAME), which doesn't initialize the moving vectors - and yet it goes into this area anyway and promptly blows up because the moving vectors are garbage. I'm not sure what I'm doing wrong. Here's my encryption initialization: theora_info_init(&m_ti); m_ti.width=176; m_ti.height=144; m_ti.frame_width=176; m_ti.frame_height=144; m_ti.offset_x=0; m_ti.offset_y=0; m_ti.fps_denominator=(ogg_uint32_t)1000000.0; m_ti.fps_numerator=10 * m_ti.fps_denominator; //10 is 10 frames per second m_ti.aspect_numerator=1; m_ti....

Hi, Attached is my patch to add theora encoding to ffmpeg's libavcodec (by using libtheora). I am requesting help to fix the bug I mention below and am seeking general comments before I submit the patch properly. Files encoded using this encoder have a problem playing in VLC. The files will not play unless "Drop late frames" has been unticked in the advanced video settings.

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.

Hello, I am programmer working on a product which integrates Theora. I have a question regarding the memory use on some of the internals of Theora. Is this the right forum for this question, and if not, does anyone know where an appropriate place to ask is? Thanks Sam -------------- next part -------------- An HTML attachment was scrubbed...
