This is a second version of the patch series adding a plugin for the
Exynos4 camera.
================
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 {
source_entity: s5p-mipi-csis.0
source_pad: 1
sink_entity: FIMC.0
sink_pad: 0
}
v4l2-controls {
Color Effects: fimc.0.capture
Saturation: S5C73M3
Image Stabilization: S5C73M3
White Balance, Auto & Preset: S5C73M3
Exposure, Metering Mode: 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.
Thanks,
