media: vb2: add V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF

2019-10-21T10:37:57+00:00

This patch adds support for the V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF flag. It also adds a new V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF capability. Drivers should set vb2_queue->subsystem_flags to VB2_V4L2_FL_SUPPORTS_M2M_HOLD_CAPTURE_BUF to indicate support for this flag. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: add V4L2_CTRL_TYPE_AREA control type

2019-10-10T14:36:32+00:00

This type contains the width and the height of a rectangular area. Reviewed-by: Jacopo Mondi Signed-off-by: Ricardo Ribalda Delgado Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: videodev2.h: add V4L2_FMT_FLAG_DYN_RESOLUTION

2019-08-19T17:56:31+00:00

Add an enum_fmt format flag to specifically tag coded formats where dynamic resolution switching is supported by the device. This is useful for some codec drivers that can support dynamic resolution switching for one or more of their listed coded formats. It allows userspace to know whether it should extract the video parameters itself, or if it can rely on the device to send V4L2_EVENT_SOURCE_CHANGE when such changes are detected.

media: videodev2.h: add V4L2_FMT_FLAG_CONTINUOUS_BYTESTREAM

2019-08-19T17:41:45+00:00

Add an enum_fmt format flag to specifically tag coded formats where full bytestream parsing is supported by the device. Some stateful decoders are capable of fully parsing a bytestream, but others require that userspace pre-parses the bytestream into frames or fields (see the corresponding pixelformat descriptions for details). If this flag is set, then this pre-parsing step is not required (but still possible, of course).

media: videodev2.h: change V4L2_PIX_FMT_BGRA444 define: fourcc was already in use

2019-07-11T13:00:38+00:00

The V4L2_PIX_FMT_BGRA444 define clashed with the pre-existing V4L2_PIX_FMT_SGRBG12 which strangely enough used the same fourcc, even though that fourcc made no sense for a Bayer format. In any case, you can't have duplicates, so change the fourcc of V4L2_PIX_FMT_BGRA444.

media: videodev2.h: Fix shifting signed 32-bit value by 31 bits problem

2019-06-21T20:45:59+00:00

Fix v4l2_fourcc define to use "U" cast to avoid shifting signed 32-bit value by 31 bits problem. This isn't a problem for kernel builds with gcc. This could be problem since this header is part of public API which could be included for builds using compilers that don't handle this condition safely resulting in undefined behavior.
