Let me just go through the code and architecture there. I will try to test it on OMAP board in this weekend. Finally I am trying to prepare separate char driver like mga_vid - to get overlay interface done. The beauty I want to add there is let user pass virtual address of frame and then drv will convert to physical add, and they dma it to output device. Again there is lots of physically contigous memory gets consumed for this 2 overlay planes (i.e dma_alloc_coherent (...)). I am also asking v4l2 and linux-omap-open-source guys on better interface in such situations. Let us see, what they reply. ===== ---Komal Shah __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
