[Live-devel] RTP stream retransmit

[Zvika Meiseles]

I've written some code using the live555 library that receives an RTP MPEG2
stream, converts it to TS and transmits it using RTP to another address.

The incoming RTP stream is a live feed coming from a camera.
In order not to be vulnerable to networking delays, I've implemented a
FramedFilter that takes the TS packets and puts them in a queue.
The "client" of this queue is a SimpleRTPSink, which reads them through a
MPEG2TransportStreamFramer.
The frames are "released" from the queue after a slight delay.
The idea was for the "Framer" to read the frames in near-live rate, and the
RTPSource to put frames into the queue in near-live rate. The initial
amount of "queued frames"  should allow slight differences between in/out
rates.

My problem is that the "Framer" reports most of the frames' duration as
"0.0", and as a result 'uSecondsToGo' in the RTPSink is always 0, and the
frames are sent out too fast.

Any idea how to get this to work?
