Andy Walls 22dce188ef V4L/DVB (13430): cx18: Fix YUV capture so that encoder passes a single frame per transfer ... Fix YUV capture such that the encoder will pass one frame per transfer. This will allow the application to maintain frame alignment when a transfer from the encoder is missed due to high system latency in service the CX23418 IRQ. Also force YUV buffer sizes to be specified in multiples of 33.75 kB, the smalled amount of buffer sizes need to store a complete set of HM12 4:2:0 macroblocks specifying 32 lines of the frame. A full 60Hz/525 line screen requires 15 * 33.75 kB per frame and a full 50Hz/625 line screen requires 18 * 33.75 kB per frame so the default buffer size is 3 * 33.75 kB, requiring exactly 5 or 6 buffers per MDL respectively. The bytes needed per frame and hence MDL need not be the bytes in an integer number of buffers. However, if frame artifacts are seen with scaled screen sizes, the YUV buffer size can be set 34 kB (33.75 kB) to get rid of the artifacts at the cost of more copies between the kernel and userspace.
