Ross, Thanks a lot! I could've been looking for this sync for ages! Is it possible to have a Mux process a "Master" Pid (video) and periodically set an event trigger (providing the current timing)? The other DataStreamFramer should wait for this event and deliver its data when it arrives. I could not figure out how to start the Framer idle and provide one frame on request...

I'm trying to mux a H264 elementary stream along with the private data into MPEG TS. It should be done offline, with 2 files - video and data. I've added the support for data in the MPEG2TransportStreamMultiplexor ( PMT and other stuff ), and this works. The problem is that I only get data packets inserted in the resulted file until the first video packet (something like 5 packets). After that, only video packets are present. I think the problem you're facing is that our Transport Stream multiplexing code inserts chunks of data - from each source - as soon as it gets them, regardless of how the chunks of data is timestamped. I.e., it *doesn't* use the timestamps to make sure that all of the chunks of data get inserted into the Transport Stream in timestamp order. The reason for this is that the code was intended to multiplex live sources, or data from a single file only (as we do with our "testH264VideoToTransportStream" demo application). Your solution, therefore, is to (somehow) make your data sources 'live' streams, delivering data to their downstream object (in this case, the Transport Stream multiplexor) only at the appropriate time, rather than immediately.
