Hi all, The only change to the agenda has been that after the Qualcomm presentation there will also be a short presentation from ST-Ericsson on their hardware. We are also completely full. The substantial interest in this summit shows how active the v4l community is, in particular in the area of embedded systems. If I've missed a topic or you want to add one, please contact me! The Saturday before the summit I'll post the final agenda and with all the topics in order. Note that I am also moving to a new apartment this month, so I'm not as often online as I normally am.
