I'd like to give a small (20 min?) presentation about AVB (Audio Video Bridging, http://en.wikipedia.org/wiki/Audio_Video_Bridging) and possibilities to implement audio/video streaming and parts of AVDECC in ALSA/V4L2 (AVDECC = AVB Discovery, Enumeration, Connection management and Control).
It's very early days, so this is more about what it is and what the advantages are of handling part of it in the kernel.
Regards,
Hans
