Methods and apparatus for supporting encoding, decoding and/or transcoding of content streams in a communication system

Methods and systems for supporting parallel processing utilizing Central Processing Unit(s) (CPU(s)) and at least one Graphics Processing Unit (GPU) device to provide high scale processing of content streams. An exemplary method embodiment including the steps of: receiving at a CPU multiple data units corresponding to a first frame time for each of first through Nth content streams; sequentially processing by the CPU data units corresponding to different content streams and the first frame time; operating a set of cores of a GPU, in parallel, to perform processing on a set of data units, processing including operating each core of the set of cores to perform an operation on a data unit corresponding to a single one of the first plurality of content streams, each core in the set of cores processing a data unit of a different content stream, said processing generating a set of generated data units.
