For those of you who are using the Ohci DMA code. Is there a way to determine if the frame in the dma buffer is valid? The DMA has a counter right, so if we have the number of bytes in one frame before a frame start we have a valid frame. I have some chopped frames one in a while, say 1/3 of the new frame and 2/3 the last frame that was on that position in the dma buffer. Are there also ideas about how multiple cameras should be handled is they are to be used with different applications? Any suggestions how to do any of this in a nice way? Thanks, Bart By the way what is the recent status of the Sony Ohci chipset? |
