I'm a Jitter beginner trying to use a jit.matrix.set as a recordbuffer for my Isight camera. Basicaly I wan't to record up to 10 seconds to memory and then play around with it.

My first problem is that I would like to dynamicaly allocate how many frames the matrixset uses (I will have several of these buffers and would like to conserve memory), but I can't get it to work. I've tried to send a matrixcount message before every increase in index, but it just slows down my machine to a crawl and doesn't record anything except black frames. I also tried to start at ten frames and increase matrixcount from there, but the result is the same. Of course everything works fine if I predefine matrixcount.

Second problem is that I would like to have a mode where the buffer always keeps the ten previous seconds from a live feed so I can srub in it, but I have no idea how to acomplish this since the write and read methods both uses the index message.

Any suggestions would be very appriciated.

Two jit.matrixset questions?
