Hi, I would like to experiment with a scheduling algorithm for video multicasting. The algorithm is based on dividing a video into several segments, each multicasted through a separate channel (port). I have recently been looking into the live555 library as part this work for my master thesis.
My goal right now is to: - Open a file with several file descriptors, each pointing to a separate segment of the movie. - Set up several channels, one for each segment of the movie. - Multicast each segment of the movie at different bandwidths. The current file format I have worked with is MPEG2. So far I have attempted to try streaming the same file over two channels (or, four, one for video and one for audio, opening the same file twice) by adding extra Ports and corresponding RTPSinks (which gives me a seg.fault which I have not yet investigated the cause of - crashes when calling rtpSink->startPlaying()). Does anyone have experience with anything similar? Is there any support in live555 that I have not seen that enables this type of functionality? If no, does anyone have hints or suggestions to what classes should be modified (or added) to add such functionality? I want to mention that this is my first experience working directly with media streams, hence I am new to a lot of the terminology. Do not hesitate to ask me if there is anything that is unclear. Thanks for any input that might be of help, Best regards, Tonje Fredrikson _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
