Adapt to new controls (subsampling). For encoding, the destination format now needs to be set to V4L2_PIX_FMT_JPEG and the subsampling (4:2:2 or 4:2:0) needs to be set using the respective control (V4L2_CID_JPEG_CHROMA_SUBSAMPLING). Required buffer size for destination image during encoding is no longer deduced from the format (which generally implied overestimation), but needs to be given from userspace in sizeimage. Not strictly related to the added controls, this patch also fixes setting the subsampling of the destination image for decoding, depending on the destination format. Signed-off-by:

Some video devices need to use contiguous memory which is not backed by pages as it happens with vmalloc. This patch provides USERPTR handling for those devices. Signed-off-by:

The devm_* functions are used in the platform device probe() for data that is freed on driver removal. The managed device layer takes care of undoing actions taken in the probe callback() and freeing resources on driver detach. This eliminates the need for manually releasing resources and simplifies error handling. Signed-off-by:

Add support for cropping and composition setup on the video capture node through VIDIOC_S/G_SELECTION ioctls. S/G_CROP, CROPCAP ioctls are still supported for applications since the core will translate them to *_selection handler calls. Signed-off-by:

This patch replaces VIDIOC_S/G_JPEGCOMP ioctl handlers with V4L2_CID_JPEG_QUALITY control. Additionally it enables JPEG subsampling and the restart interval configuration through V4L2_CID_JPEG_SUBSAMPLING and V4L2_CID_JPEG_RESTART_INTERVAL controls. For the decoder video node only V4L2_CID_JPEG_SUBSAMPLING is available as a read-only control. Signed-off-by:

Add DocBook entries for the JPEG control class. Signed-off-by:
-
Sylwester Nawrocki authored
The V4L2_CID_JPEG_CLASS control class is intended to expose various adjustable parameters of JPEG encoders and decoders. Following controls are defined: - V4L2_CID_JPEG_CHROMA_SUBSAMPLING, - V4L2_CID_JPEG_RESTART_INTERVAL, - V4L2_CID_JPEG_COMPRESSION_QUALITY, - V4L2_CID_JPEG_ACTIVE_MARKER. This covers only a part of relevant standard specifications. More controls should be added in future if required. The purpose of V4L2_CID_JPEG_CLASS class is also to replace some functionality covered by VIDIOC_S/G_JPEGCOMP ioctls, i.e. the JPEG markers presence and compression quality control. The applications and drivers should switch from the ioctl to control based API, as described in the subsequent patches for the Media API DocBook. Signed-off-by:
