[streaming] how to get network information?

[Marshall Eubanks]

If you are streaming multicast RTP rtpqual and rtpdump can be used to  
do this using RTCP
reports.

This is especially easy if you are using a fully RTP compliant  
receiver, as the
receiver reports include exactly the information you want. I
do not know if VLC supports RTCP, but Quicktime does.

I also don't know if rtpdump and rtpqual have been given unicast  
options, but the code is open source and
that shouldn't be very difficult.

(Note that Quicktime, under

Window -> Show Movie Properties -> Streaming Track -> Statistics

has useful plots of bit rate, loss and buffer size, but I know of no  
way to export this information.)

Marshall
