[pandaboard] OMAP4460 stereo camera capture using gst-launch-0.10

[Aswin Karthik Ramachandran Venkatapathy]

Hi,
I am using the Ubuntu 12.04 on my OMAP4460 based board (DART-4460) which
has 2 CSI2-MIPI interface.
I used the following GST pipeline code on the CLI.

DISPLAY=:0 gst-launch -e omx_camera *device=2* do-timestamp=1 mode=0
name=cam cam.src ! \
"video/x-raw-yuv, format=(fourcc)NV12, width=1280, height=720,
framerate=24/1" ! tee name=t1 t1.\
! queue ! *ducatih264enc* profile=66 level=40 rate-preset=low-delay
bitrate=4000 ! h264parse ! \
queue ! avimux ! filesink location=*foo.avi* t1. ! queue ! dri2videosink
sync=false

device=2 give me the following output, check the video:
https://www.akrv.xyz/foo.avi

Now, stereo capture is working but the output colourspace is not desired
and I am not able to change it.
is there any idea how i can change the colourspace, i tried a lot of things
changing the encoder, i think i m missing something.
does anyone in the forum have gone through this?

with best regards
Aswin
