Multistandard video decoder

A non-transitory computer-readable storage having stored thereon, a computer program having at least one code section for processing video, the at least one code section being executable by a machine to perform steps comprising:

• performing by one or more processors and/or circuits:
• receiving packetized data within an encoded video stream;
• determining a start code within said received packetized data, wherein the start code defines a start of a payload in said received packetized data;
• determining an identifier within said received packetized data that defines one of a plurality of encoding types associated with packets in the encoded video stream;
• selecting a decoding process from a plurality of decoding processes based on said determined identifier, wherein said plurality of decoding processes comprises a fixed length coding (FLC) process, a variable length coding (VLC) process and a context adaptive binary arithmetic coding (CABAC) process;
• removing a stuffing byte from said start code in the packetized data;
• and
• decoding, at least a portion of said received packetized data in the encoded video stream utilizing said selected decoding process.
