For this project I will probably have to build a custom tool that uses ffmpeg for transcoding. VLC might be a good place to start but the codebase is pretty large if I have to customise it so it's probably faster to start from scratch. > Concerning the sync, if you mean audio with video, what we were doing did > not require synced audio. > This project probably doesn't require realtime sample accurate sync but the latency should be within 2000ms between audio and video streams and also between master/client. Latency should be as low as possible with a balance between cpuload and bandwidth management.
