Stin, Bitrate is controlled via the rate control algorithm of encoder, which basically plays with the quality , not chnaging any parameters you mentioned in bitrate. Hence you see the quality change while playing back.

If I play the generated stream, I can see indeed a quality change when I change the bitrate while playing. But what I don't know is what exactly is changing? Bitrate = Width x Height x Colordepth x PixelsPerFrame Is it the PixelsPerFrame parameter that is changing when I change the bitrate?
