Hi,
Currently I'm working on TI8148 with adv7180 encoder/decoder attached to VIN[0] port A.
I am using saLoopBack application to capture the video from the adv7180.
When I executed saLoopBack, I encountered the following error at startCapture. It is failed in Fvid2 device create.
LOG:

I had set capture device as /dev/video0.
I had set fb device as /dev/fb0.
I have to capture 720x576 data in YCbCr format.
Here is my configurations:

Are the above configurations correct ?
Please Clarify me.
