Timestamped video frames in OpenCV video stream Python C

And I use ByteStreamFileSource.cpp and ADTSAudioFileSource.cpp to get the frame data. For h264/aac sync, I use testProgs/testOnDemandRTSPServer.cpp to do: 2. At H264 sub session with 30fps, that mean H264 task will call doGetNextFrame() 30 times per sec. Each time, our code will make sure doGetNextFrame() get one H264 frame(I or P) to deliver to fTo. So, doGetNextFrame() may be blocking by ring buffer. 3.
