Did you define a PayloadType for your MPEG2 stream at 48khz ?
I didn't, no. I have changed it now, and created a PayloadType 14,
with a 90kHz timestamp clock (as RFC2250). It is now sending out RTCP
packets at a much more sensible rate.
PayloadType payload_type_mpeg_audio={
PAYLOAD_AUDIO_PACKETIZED, // type
90000, // clock rate
0, // bytes per sample N/A
NULL, // zero pattern N/A
0, // pattern_length N/A
0, // normal_bitrate
"mpa", // MIME Type
0 // flags
};
I didn't set any of the other parameters, because I am sending out
multiple streams, with different bitrates from a single process.
Is there are a reason that this static payload type wasn't already
built-into oRTP?
Thanks for your help,
nick.

Hi,
I am using oRTP to send multicast audio in my program 'dvbshout':
http://www.ecs.soton.ac.uk/~njh/dvbshout/
However it looks like oRTP is sending out an RTCP packet for every
RTP packet sent. Should oRTP automatically be adjusting the rate (and
keeping it below 5% of the total datarate)? I am not using Scheduled
or Blocking modes.
Details of test stream are here:
