Hello, I think I've figured out how to cleanly synchronise audio and video with RAOP with relying on my empirical "shifting audio 2300ms in mplayer works". The attached patch adds 2000ms of latency (as spec'ed by Apple from what I've found on the internet) plus the length of the last audio packet sent to the initial latency calculation. This works great on my computer. The added latency is 2352ms which is very close to my empirical finding. I'd love for others to test it with different hardware (mine's a Pioneer N-30) and if it's deemed good, to have it merged upstream! PS: here's a video showing the synchronisation (sorry, when slowed out too much, you can't really hear the "bops" : https://www.youtube.com/watch?v=iOs6XYpNdos (At the beginning, sync isn't perfect, I suspect it's due to the connecting etc.) -- Colin -------------- next part -------------- A non-text attachment was scrubbed...
