Rate control is clunky... >> res: 160x128 320kBit 10fps No go 320kBit 6fps great 160kBit 6fps Significantly worse quality (noiselike Artifacts) 160kBit 3fps ~ ok quality noticeable jumpiness in motion Noticable the Keyword VideoSize even though specfied in the sample is not so supported - how is it really handled ?
