Forum Post: Can't chain IPIPE while capturing low resolution video

$

Hi,

 

We are trying  to capture a video from a source with non-standard resolution using DM365-based card.

The format of the video is UYVY and the resolution is 752X288.

The gstreamer command we are using is:

gst-launch -v v4l2src always-copy=false input-src="Camera" ! "video/x-raw-yuv, format=(fourcc)UYVY, width=(int)752, height=(int)288" ! fakesink

After running the above command, no buffers are printed to the screen.

 

IMPORTANT: We succeed to capture video with the non-standard resolution when the IPIPE is not chained.

 

We get the same issue when using Aptina sesnor (MT9M021) configured to the above non-standard resolution (We also tried other non-standard resolutions with no success).

 

1. Is it hardware issue or software (driver) issue?

2. How can we overcome this issue?

 

Regards,

Sheldon
