This is a third version of the patch series adding a plugin for the Exynos4 camera. Temporarily the plugin doesn't link against libmediactl, but has its sources compiled in. Currently libmediactl.la is built after the plugins and this will have to be resolved somehow. ================ Changes from v2: ================ - switched to using mediatext library for parsing the media device configuration - extended libmediactl - switched to using libmediactl ================ Changes from v1: ================ - removed redundant mbus code negotiation - split the parser, media device helpers and ioctl wrappers to the separate modules - added mechanism for querying extended controls - applied various fixes and modifications The plugin was tested on latest media-tree.git master with patches for exynos4-is that fix failing open when a sensor sub-device is not linked [1] [2] [3]. The plugin expects a configuration file: /var/lib/libv4l/exynos4_capture_conf Exemplary configuration file: ========================================== link-conf "s5p-mipi-csis.0":1 -> "FIMC.0":0 [1] ctrl-to-subdev-conf 0x0098091f -> "fimc.0.capture" ctrl-to-subdev-conf 0x00980902 -> "S5C73M3" ctrl-to-subdev-conf 0x00980922 -> "fimc.0.capture" ctrl-to-subdev-conf 0x009a0914 -> "S5C73M3" ========================================== With this settings the plugin can be tested on the exynos4412-trats2 board using following gstreamer pipeline: gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,width=960,height=720 ! fbdevsink In order to avoid fbdevsink element failure the fix [4] for exynos-drm driver is required.
