search for: offset_y

...ication using theora, I checked the difference between the two executions. And it seems that the function *_theora_decode_header_* does not have the same issue in the two application, but I read the same file... the difference is on the _m_theoraInfo_, in the first application ( which work ) the offset_y is equal to 4, and in the second application (which does not work) the offset_y is equal to 0. that's the same file at two differente place in the file system, but I suppose that changes nothing ? How can I get differente information about the same file ?? Vincent.

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.

I'd previously been working on the assumption that the frame_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

Hi, I have a question about the format of Theora bitstream header. It seems to me that there are differences between the specification[1] (version 2004 Oct 1) and its reference implementation in libtheora 1.0alpha3 released at 2004 Jun 1. I mean that... please refer to Section 6.2 'Identification Header Decode' in that specification[1] and the function

hi folks! once again i am trying to decode a yuv_buffer to a 24 bit RGB buffer. last time nobody seemed willing to tell me how to do this, so i am trying again. i try to make my questions more simple. what i need to know is: how many bytes are in each y, u, v array? what for are these strides? what exactly is a "plane" in a frame, and what does it do? what i want to achieve is

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.
