Abstract: Methods and apparatus for video processing are disclosed. In one embodiment the work of processing of different types of video frames is allocated between a plurality of computing resources. For example, different computing resources for can be used for I, P and B frames, where an I frame is an intra-frame encoded with no other frames as a reference; a P frame is encoded with one previous I or P frame as a reference and a B frame is encoded with one previous and one future frame as references. In one example, a central processing unit (CPU) performs encoding of I frames and P frames of a video and a graphics processing unit (GPU) performs initial encoding of B frames of the video in connection with a fixed function video encoder configured to perform entropy encoding of the B frames.

Abstract: A processing device and method for executing a color twist operation are provided. The processing device comprises memory and a processor configured to convert values of pixels of a frame from a first color domain to a hue, saturation and value (HSV) color domain, adjust hue values and saturation values of the pixels, store the adjusted hue and saturation values in a portion of the memory local to the processor and convert the frame from the HSV color domain to the first color domain using the adjusted hue and saturation values stored in local memory. The adjusted hue and saturation values are generated from pre-adjusted values, which are generated from masked vector values.
