But at the same time on transmiting a RTP packet,I need to capture a
frame into the buffers from the live souce(e.g,such like a
webcamera).Does it need mutithread programming?
No. You can do this, within a single event loop, with a chain of
three objects:
FrameCapture => Encoder => RTP_Sink
where:
- "FrameCapture" is an instance of a new class (that you
would write) that subclasses "FramedSource". You should look at the
"DeviceSource" code as a model for how you might do this.
- "Encoder" is an instance of a new class (that you would
write) that subclasses "FramedFilter". It would compress each frame
using your chosen codec.
- "RTP_Sink" is an instance of the appropriate subclass of
"RTPSink" (depending on the codec).
You would begin the streaming by calling
RTP_Sink->startPlaying(Encoder, ...);
and then
env->taskScheduler().doEventLoop();
to start the event loop.
