2022-11-04media: v4l: Add definition for the Aspeed JPEG formatJammy Huang1-0/+1
This introduces support for the Aspeed JPEG format, where the new frame can refer to previous frame to reduce the amount of compressed data. The concept is similar to I/P frame of video compression. 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.

2022-07-15media: videodev2.h: add V4L2_CTRL_FLAG_DYNAMIC_ARRAYHans Verkuil1-0/+1
Add a new flag that indicates that this control is a dynamically sized array. Also document this flag. Currently dynamically sized arrays are limited to one dimensional arrays, but that might change in the future if there is a need for it. The initial use-case of dynamic arrays are stateless codecs. A frame can be divided in many slices, so you want to provide an array containing slice information for each slice. Typically the number of slices is small, but the standard allow for hundreds or thousands of slices. Dynamic arrays are a good solution since sizing the array for the worst case would waste substantial amounts of memory.

2021-03-22media: uapi: move VP8 stateless controls out of stagingEzequiel Garcia1-0/+1
Until now, the VP8 V4L2 API was not exported as a public API, and only defined in a private media header (media/vp8-ctrls.h). The reason for this was a concern about the API not complete and ready to support VP8 decoding hardware accelerators. After reviewing the VP8 specification in detail, and now that the API is able to support Cedrus and Hantro G1, we can consider this ready.

2020-12-07media: doc: pixfmt-rgb: Clarify naming scheme for RGB formatsLaurent Pinchart1-1/+3
The naming scheme for the RGB pixel formats has been developed organically, and isn't consistent between formats using less than 8 bits per pixels (mostly stored in 1 or 2 bytes per pixel, except for RGB666 that uses 4 bytes per pixel) and formats with 8 bits per pixel (stored in 3 or 4 bytes). For the latter category, the names use a components order convention that is the opposite of the first category, and the opposite of DRM pixel formats. This has led to lots of confusion in the past, and would really benefit from being explained more precisely. Do so, which also prepares for the addition of additional RGB pixels formats.

The V4L2_PIX_FMT_BGRA444 format has a comment that explains why its 4CC value is GA12. This explains the development history and isn't of much interest to readers, it should have been part of a commit message instead. Drop the comment, anyone interested in history can turn to git.

2020-12-03media: vicodec: mark the stateless FWHT API as stableHans Verkuil1-0/+3
The FWHT stateless 'uAPI' was staging and marked explicitly in the V4L2 specification that it will change and is unstable. Note that these control IDs were never exported as a public API, they were only defined in kernel-local headers (fwht-ctrls.h). Now, the FWHT stateless controls is ready to be part of the stable uAPI. While not too late: - Rename V4L2_CID_MPEG_VIDEO_FWHT_PARAMS to V4L2_CID_STATELESS_FWHT_PARAMS. - Move the contents of fwht-ctrls.h to v4l2-controls.h. - Move the public parts of drivers/media/test-drivers/vicodec/codec-fwht.h to v4l2-controls.h. - Add V4L2_CTRL_TYPE_FWHT_PARAMS control initialization and validation. - Add p_fwht_params to struct v4l2_ext_control.

The H.264 stateless 'uAPI' was staging and marked explicitly in the V4L2 specification that it will change and is unstable. Note that these control IDs were never exported as a public API, they were only defined in kernel-local headers (h264-ctrls.h). Now, the H264 stateless controls is ready to be part of the stable uAPI. While not too late, let's rename them and re-number their control IDs, moving them to the newly created stateless control class, and updating all the drivers accordingly.
