| * media: Add Y012 video formatMing Qian2023-04-151-0/+15
| | | | | | | | | | | | | | | | | | | | | | Y012 is a luma-only formats with 12-bits per pixel, expanded to 16bits. Data in the 12 high bits, zeros in the 4 low bits, arranged in little endian order.

| | | | | | | | | | | | | | | | | | | | | | | | P012 is a YUV format with 12-bits per component with interleaved UV, like NV12, expanded to 16 bits. Data in the 12 high bits, zeros in the 4 low bits, arranged in little endian order. And P012M has two non contiguous planes.

| * media: v4l2-subdev: Add new ioctl for client capabilitiesTomi Valkeinen2023-04-152-0/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new ioctls to set and get subdev client capabilities. Client in this context means the userspace application which opens the subdev device node. The client capabilities are stored in the file handle of the opened subdev device node, and the client must set the capabilities for each opened subdev. For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which indicates that the client is streams-aware. The reason for needing such a flag is as follows: Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain reserved fields (usually a single array field). These reserved fields can be used to extend the ioctl. The userspace is required to zero the reserved fields. We recently added a new 'stream' field to many of these structs, and the space for the field was taken from these reserved arrays. The assumption was that these new 'stream' fields are always initialized to zero if the userspace does not use them. This was a mistake, as, as mentioned above, the userspace is required to zero the _reserved_ fields. In other words, there is no requirement to zero this new stream field, and if the userspace doesn't use the field (which is the case for all userspace applications at the moment), the field may contain random data. This shows that the way the reserved fields are defined in v4l2 is, in my opinion, somewhat broken, but there is nothing to do about that. To fix this issue we need a way for the userspace to tell the kernel that the userspace has indeed set the 'stream' field, and it's fine for the kernel to access it. This is achieved with the new ioctl, which the userspace should usually use right after opening the subdev device node.

| | | | | | | | | | | | | | | | | | | | | | | | | | RealVideo, or also spelled as Real Video, is a suite of proprietary video compression formats developed by RealNetworks - the specific format changes with the version.

While most parameters will be "read-only" due to being autodetected by the receiver and only being reported back for informational purposes, the addition of SYS_DVBC2 to the delivery systems enum is required, because there are DVB-C2 capable receivers which are not capable of DVB-C/C2 autodetection and thus need this enum value to be explicitly instructed to search for a DVB-C2 signal. As for DVB-S2X, as that is an extension to DVB-S2, the same delivery system enum as for DVB-S2 can be used. Add the additional enum values and comments to the documentation.

It will compare the new frame with previous one to decide which macroblock's data is changed, and only the changed macroblocks will be compressed. This Aspeed JPEG format is used by the video engine on Aspeed platforms, which is generally adapted for remote KVM.
