Setting RGB quantization range for HDMI output

I am using nvdrmvideosink to output RGB video to an HDMI display, and I suspect there is some issue with regard to the RGB quantization range being reported by the Jetson in the HDMI AVI infoframes. Is there a way to explicitly set the quantization range that is being sent in the infoframes to the display, or at the very least a way to log these infoframes?


We are still checking if any method.
