I figured out the issue with using the UDP as a source for the MPEG2TransportStreamDemux: It seems to be an issue with the StreamParser, when it is ensuring valid bytes the number of bytes that are needed is only 1 but the UDP source is reading ~940 bytes. So, the if statement: fCurParserIndex + numBytesNeeded > BANK_SIZE never becomes true, thus never switching the parser banks. I fixed this issue by subclassing the BasicUDPSource and overriding the maxFrameSize function to something > ~940. With this now working I now need to figure out how to hookup the MPEG2TransportStreamDemux to the H264VideoRTPSink. I believe it should go something like this: MPEGTS Multicast Stream -----> BasicUDPSource -----> MPEG2TransportStreamDemux -----> H264VideoRTPSink However, I understand I don't have the ability to specify the sink for the various demuxed elementry streams. Is there any way this could be added or subclassed to allow such a thing? Thank you, Josh
