Hello all, When I'm doing something like: yuv_buffer yuv; theora_decode_YUVout(&td,&yuv); I'm guessing a bunch of stuff gets newed/malloced for yuv.y, yuv.u, and yuv.u. Who is responsible for deleting/freeing that stuff? Cheers, Kos.

...ived by a Theora decoder 4) "theora_encode_comment" need never be called, but can be called at any time, and its packet can be inserted anwhere 5) "theroa_encode_tables" must be called exactly once, and its output must be the first non-comment packet after the header 6) "theora_encode_YUVin" must be called once per frame, and its output added to the stream in a sequential manner 7) Theora can tolerate any number of "dropped packets", so long as the packet is not "header", "tables", or (perhaps) the first "YUVin". As you can see, I'm m...

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.
