I have been tasked with writing trick play logic to work with the Video Propulsion Q4LP QAM card, so as a proof-of-concept I am trying to use the "testMPEG2TransportStreamTrickPlay" test program to generate a 8x scaled file to simulate Fast-Forward. The file I generated plays fine on VLC and WMP, h

hi! I'm new to this discussing list, and I am working with a project, part of it is to implement a media streamer and receiver using RTP payload. I found livemedia is useful, but it's a c++ library, and the other part of the project is written by python. I wonder how can I use the library with
