similar to: dynamic change video quality........

Here is a fix that prevents the encoder from spending too many bits on keyframes. The main problem is that the old code computes the target keyframe bitrate incorrectly. This causes the code that computes the Q for the frame to think that it has tons of bits to spend. It selects a high Q value for the keyframe. Since so many bits were spend on the keyframe the the inter-frames have to use a much

Here is a patch that fixes distortions that appear during scenes with no motion. Tbe problem was that UpdateFrame() was not being called when a MotionScore of 0 was computed. Since UpdateFrame() was not called the buffer returned by theora_encode_packetout() would be the same buffer that was output for the last frame that had a non-zero MotionScore. This is obviously incorrect behavior. I've

Theora can encode video with several quality parameters. So when that encoded video is decoding it should be looked at quality value. For a single video, decoder get first frame quality value for all video frame or decoder get each quality value for each frame? -- Asanka Dilruk Department of Computer Science and Eng.

Hi, Can we encode a normal stream in to black & white video using exsisting encoder_example in theora_beta2. Is it required to change encoder_example file to do that? So please guide to do that. Thanks... -- ___ -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, We want to get a B&W output from any video input (B&W or Color). So when we encoded into B&W video compression will be increased is it correct? Can we archive this by a existing encoder_example. -- ___ -------------- next part -------------- An HTML attachment was scrubbed...

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
