That's true, fortunately. Applications and/or the MPEG decoder must explicitely support MPEG-1, but the demux API can be the same for both MPEG-2 PS and MPEG-1 system streams. OTOH, I think there's no need to support MPEG-1 (or MPEG-2 PS) in the software demux. If you have a hw MPEG-1 decoder, the hw will have MPEG-1 demux capabilites; if not, if does not make sense to pass data into the kernel for demuxing. > Second i'm not sure if we need to support mpeg-1 systems. > DVD does not use it , broadcaters do not use it. If you want the DVD(tm) logo on your box you must support VCD (correct me if I'm wrong, but I think backwards compatibility is part of the DVD spec; also the MPEG2 spec says: "The Program Stream of this Recommendation | International Standard is defined to be forward compatible with ISO/IEC 11172-1. Decoders of the Program Stream as defined in this Recommendation | International Standard shall also support decoding of ISO/IEC 11172-1.")
