Reproducer:
{{{
gst-launch-0.10 v4l2src ! ffmpegcolorspace ! pngenc ! filesink
location=foo.png
eog foo.png
}}}
Displayed image has incorrect colours.
Alternate reproducer:
* disable YUV support in driver, recompile, reboot,
* use Sugar Record activity or GStreamer pipeline
{{{
gst-launch-0.10 v4l2src ! xvimagesink
}}}
With ov7670 sensor, the problem does not occur.
In Open Firmware the problem does not occur. Correct image data is
displayed:
{{{
select /camera / defaults to RGB565 mode
.properties \ verify SIV120D
start-display
}}}
Same sensor register settings used, so this is probably a CCIC
configuration or data interpretation issue.
