Hello Everyone, This is the fifth version of extended crop/compose RFC. It was updated after Laurent's review. The patch-set introduces new ioctls to V4L2 API for configuration of selection rectangles like crop and compose areas. The last patch adds selection support for s5p-tv driver. Please refer to discussion below for more details about api development. http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/32152 Changelog: v4: - removed returning best-hit rectangle on failure of VIDIOC_S_SELECTION - fixed typos and naming - removed enums from structures - code style cleanup v3: - added target for padded buffer - reduced number of constraint flags to SIZE_LE and SIZE_GE - removed try flag - added documentation for selection ioctls - added documentation for new model of cropping, composing and scaling - support of selection api for s5p-tv - fixed returning ioctl's structures on failure v2: - reduced number of hints and its semantics to be more practical and less restrictive - combined EXTCROP and COMPOSE ioctls into VIDIOC_{S/G}_SELECTION - introduced crop and compose targets - introduced try flag that prevents passing configuration to a hardware - added usage examples Tomasz Stanislawski (4): v4l: add support for selection api v4l: add documentation for selection API v4l: emulate old crop API using extended crop/compose API v4l: s5p-tv: mixer: add support for selection API Documentation/DocBook/media/constraints.png.b64 | 134 + Documentation/DocBook/media/selection.png.b64 | 2937 ++++++++++++++++++++ Documentation/DocBook/media/v4l/common.xml | 4 +- Documentation/DocBook/media/v4l/selection-api.xml | 278 ++ Documentation/DocBook/media/v4l/v4l2.xml | 1 + .../DocBook/media/v4l/vidioc-g-selection.xml | 281 ++ drivers/media/video/s5p-tv/mixer.h | 14 +- drivers/media/video/s5p-tv/mixer_grp_layer.c | 157 +- drivers/media/video/s5p-tv/mixer_video.c | 339 ++- drivers/media/video/s5p-tv/mixer_vp_layer.c | 108 +- drivers/media/video/v4l2-compat-ioctl32.c | 2 + drivers/media/video/v4l2-ioctl.c | 114 +- include/linux/videodev2.h | 46 + include/media/v4l2-ioctl.h | 4 + 14 files changed, 4210 insertions(+), 209 deletions(-) create mode 100644 Documentation/DocBook/media/constraints.png.b64 create mode 100644 Documentation/DocBook/media/selection.png.b64 create mode 100644 Documentation/DocBook/media/v4l/selection-api.xml create mode 100644 Documentation/DocBook/media/v4l/vidioc-g-selection.xml -- 1.7.6 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
