Sylvain,
I work with Eugene and we discussed this solution (for low latency flowgraphs) he proposed. The solution maintains the same dual-mapped buffer, but presents a sliding window of items across it. Neither the scheduler nor the buffer know the difference other than the available items never exceeds the window size (which is less than the underlying buffer size).

I'm pretty sure the whole "dual mapped pages" circular buffer thing only works for buffer that are multiple of the page size ...

But, it's still only Sylvain and myself, so a few extra hands/eyes would be cool. Rest assured, if you volunteer, eternal hacker fame and maybe a beer will be your reward. As Martin said, you can also help if you are not coming to FOSDEM by helping us with the video cutting! In any case, hope to see lots of you guys in Brussels!
