| | | | | | | | | | | | Restructure the way the module gets loaded so that it gets loaded automatically when cx18 is loaded, and make it work properly if there are multiple cards present (since the old code would only take one opportunity to connect to cx18 instances when the module first loaded).

* V4L/DVB (13902): cx18: Update MPEG Index stream buffers module option processingAndy Walls2010-02-26
| | | | | | | | | | | | | | | | Update the module options related to INDEX stream buffer allocation. A single CX2341[5678] index entry is only 24 bytes. Large buffers for the IDX stream will prevent the CX23418 from transferring index data over at all. Buffers of around 1.5 kB or 64 index entries seem to be just fine. We'll default to 63 buffers/MDLs as that is the firmware limit per stream and IDX stream buffers are not high rate. There is no reason on earth to allocate the previous 1 MB default of buffer space for the IDX stream. This is in anticipation of implementing the G_ENC_INDEX ioctl() in the cx18 driver.

* V4L/DVB (13430): cx18: Fix YUV capture so that encoder passes a single frame ↵Andy Walls2009-12-05
| | | | | | | | | | | | | | | | | | | | | | 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.
