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.
