Hello Everyone, This is the fifth version of extended crop/compose RFC. The patch-set introduces new ioctls to V4L2 API for the configuration of the selection rectangles like crop and compose areas. Please refer to the link below for more details about the API development. http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/32152 Changelog: v4: - typos, style fixes - added piorority support to VIDIOC_S_SELECTION - removed deprecation of current crop API - marked selection as experimental API - removed references to pipeline configuration rules - added subsection about deficiencies of current cropping API - moved patches to binaries to separate patch - updated V4L2 changelog 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 (5): v4l: add support for selection api doc: v4l: add binary images for selection API doc: 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 | 2 + Documentation/DocBook/media/v4l/compat.xml | 9 + Documentation/DocBook/media/v4l/selection-api.xml | 327 +++ Documentation/DocBook/media/v4l/v4l2.xml | 1 + .../DocBook/media/v4l/vidioc-g-selection.xml | 303 ++ 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 | 120 +- include/linux/videodev2.h | 46 + include/media/v4l2-ioctl.h | 4 + 15 files changed, 4295 insertions(+), 208 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
