Hello, I'm working on a live streaming service using Live55 using an Nvidia Jetson Nano board.
I'm capturing the frames from an USB webcam and I am encoding using Nvidia's hardware encoder. Then Live555 is responsible for streaming this capture using RTSP. The Nvidia software api to use the encoder uses some threads, and I was unable to use it in a single application. I implemented 2 applications: the RTSP server and the Capture application. The communication between them is shared memory, in Linux. I implemented a circular buffer on this shared memory to place the encoded frames, which are seen by the RTSP server application. I created custom classes for MediaSession (from OnDemandServerMediaSubsession) and DeviceSource (from FramedSource). The software is almost working. I had issues with adding SPS and PPS and timestamps on the encoded frame which seems to be fine. But what is happening now is that the applications seems to be ignoring the fDurationInMicroseconds and/or the fPresentationTime values ... and the framerate does not seem to be respected when streaming. The video showing up is very fast. I would like to ask for any advice about how to properly address this problem. Best regards, Flavio
