Gray overlay over the original video frame


We have designed a video card in which we are using video decoder (ADV7604) and nVidia Jetson TX-2. When we are running following pipeline, getting following error:


gst-launch-1.0 -v v4l2src device="/dev/video0" ! video/x-raw,format=BGRA ! videoconvert ! xvimagesink -e



Please help us to understand the problem and resolve it.

Thanks and Regards,
Vikas Dwivedi

For launching v4l2 source on Jetson platforms, please take a look at

Jetson Nano FAQ
Q: I have a USB camera. How can I launch it on Jetson Nano?

Dear DaneLLL,

Thank you for your suggestion.

Problem get resolved by decreasing the offset and increasing the gain of the video decoder.

Thanks and Regards,
