| | | | | | | | | | This patch adds the VIDIOC_SUBDEV_S_CROP and G_CROP ioctls to the userland API. CROPCAP is not implemented because it's redundant.

* [media] v4l: v4l2_subdev userspace frame interval APILaurent Pinchart2011-03-221-0/+2
| | | | | | | | | | | | | | | The three new ioctl VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL, VIDIOC_SUBDEV_G_FRAME_INTERVAL and VIDIOC_SUBDEV_S_FRAME_INTERVAL can be used to enumerate and configure a subdev's frame rate from userspace. Two new video::g/s_frame_interval subdev operations are introduced to support those ioctls. The existing video::g/s_parm operations are deprecated and shouldn't be used anymore.

* [media] v4l: v4l2_subdev userspace format APILaurent Pinchart2011-03-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a userspace API to get, set and enumerate the media format on a subdev pad. The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.
