This patch adds a plugin for the Exynos4 camera. I wanted to split
at least the parser part to the separate module but encountered
some problems with autotools configuration and therefore I'd like
to ask for an instruction on how to adjust the Makefile.am files
to achieve this.
I also think that the helper functions for discovering device topology
and setting the links are reusable and should be put to the separate
module. I'm wondering what would be the most suitable place.
The plugin was tested on linux-next-20130927 with patches for
exynos4-is that fix failing open when a sensor sub-device is not
linked. This patch series is being submitted in the separate
thread.
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: S5C73M3
Saturation: S5C73M3
}
<<<<<<<<<<<<<<
With this settings the plugin can be tested on the exynos4412-trats2 board
using following gstreamer pipeline:
gst-launch-0.10 v4l2src device=/dev/video1 ! video/x-raw-rgb,width=960,height=720,format=\(fourcc\)RGBP ! ffmpegcolorspace ! fbdevsink
In order to avoid fbdevsink element failure the fix [1]
for exynos-drm driver is required.
ffmpegcolorspace element shouldn't be normally required but format
negotiation error is reported by gstreamer without it.
I am investigating the issue.
Thanks,
Jacek Anaszewski
