The presentation times that get set for the outgoing Transport Stream packets are determined *entirely* by the "MPEG2TransportStreamFramer" (that feeds into the "SimpleRTPSink").

Note that - as I noted earlier - it's the "MPEG2TransportStreamFramer" that computes the 'presentation times' of the outgoing packets. It does this by inspecting the PCR timestamps in the Transport Stream packets that are fed to it.</div><div><br></div><div>Assuming that the input Transport Stream packets have (occasional) PCR timestamps (as all Transport Streams should have), I suspect that the problem is in the implementation of your 'FrameQueue'. You can verify this by replacing the "SimpleRTPSink" with a "FileSink" - and then trying to play the output file (with a media player).</div><br><div apple-content-edited="true">
