Are you referring to Transport Stream "PAT" (Program Association Table) and/or "PMT" (Program Map Table) packets?</div><div><br></div><div>If so, then the frequency at which these packets are inserted into the output Transport Stream is determined by the constants "PAT_FREQUENCY" and "PMT_FREQUENCY", defined in "liveMedia/MPEG2TransportStreamMultiplexor.cpp". If you decrease these constants, then you will increase the frequency at which the corresponding (PAT or PMT) packets are inserted into the output stream.</div><div><br></div><div>(As you can see, these constants are actually misnamed. They should have been called "*_PERIOD", not "*_FREQUENCY".)</div><br><br><div apple-content-edited="true">
