I am new to developing using live555 so please excuse any obvious questions!
I'm trying to stream JPEG images over RTP, so I've modified the Elphel example to instead of getting a frame from a camera to read and send the same JPEG image from file. Effectively just sending the same image over and over again. Once I can do this I'll move on to generating streaming jpeg frames. The program compiles and seems to run (though wireshark says all the packets are malformed!), though the timing is constant at 250 frames per second!! No matter what frame rate I give it as an initial argument. I imagine it is because there is no delay function in my code. At the moment the 'fTimePerFrame' is set in the constructor for ElphelJPEGDeviceSource but not used anywhere. Within the doEventLoop() what is telling the process to only call doGetNextFrame() regularly (5 times per second say) rather than continuously? Should the delay function go in the startCapture() function or the doGetNextFrame() or is there a variable I need to set when adding the source to the environment taskscheduler?
