Hi, While creating identification header in the function * theora_encode_heade*r in *encoder_toplevel.c*, it assigns bits not mentioned in the current theora spec released on Octomber 29, 2007 (page 40 &41). But this implementation in function* theora_encode_heade*r is correct according to the *Figure 6.2 (page 42)*. But not according to the *table mentioned in...

...Theora, I must unpack my YUY2 data into three separate arrays (Y, U, and V respectively), and record in a "yuv_buffer" structure. 2) "yuv_buffer.y_stride" is this the number of bytes in one row of Y data. In other words, y_stride*8/y_width = num bits per Y component 3) "theora_encode_header" must be called exactly once, and its output must be the first packet received 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 onc...

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.
