[theora-dev] Changing video quality during encoding

I don't know how to change a video quality on the fly - I want to provide a
slider with a preview window, so user could see the result immediately in
this window. I tried to send ICM_COMPRESS_FRAMES_INFO to encoder or calling
ICSetState() - with no success however. Am I doing something wrong ? How can
I set 'lDataRate', 'dwRate', 'dwScale' parameters ? I tried every possible
combinations and still no effects .. 
Also changing lKeyRate seems to have no effects ... 

Thanks in advance, 

<p>Hello, i have the same problem. I don't know how to set the ICCOMPRESSFRAMES
struct correctly by using the 
intel i263 codec. Can you tell me a setting of correct values to test this
codec or can you recommend my a better codec for 128 kBit Videoconferencing?

Thank you for supporting me,
