...gets progressively blurry for each successive inter-frame. This change fixes the keyframe bitrate computation so that it is closer to the inter-frame bitrate, which I believe is what the original author intended. This prevents the huge difference in Q between keyframes and inter-frames.

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 pages 40 & 41*....

I am going to improve theora codec with dynamically changing way. In this case we want to change compression parameters like video_q, sharpness when a keyframe is generated. When i set video quality parameter using cpi-> pb.info.quality in CommpressKeyFrame in encoder_toplevel it will not change dynamically. Can you please help me to do this. Wich function should i cange to achieve my objective.... -- ___ -------------- next part -------------- An HTML attachment was scrubbed...

Hi all. I'm Mat & I'm new :) I'm testing libtheora + libogg perhaps for a commercial product. I started watching encoder_example.c ... I simplified it for testing it easier. It seems ok to me but I have no experience with theora so I would like to know if my code is correct. I tried to debug it with Valgrind and I found 4 possible memory leaks... but I think they can be
