10 Bits Per Color RGB HDMI Out Instead of 8

Hello,

Can the Nano decode and keep 10 bits per color(example HDR) and send that image data to HDMI out? If so how is this done? What APIs or player can do this and is there anything special that needs to be done to have HDMI output true 10 bits per color. Bottom line want 10 bits per color from media decode to HDMI out.

Thanks.

Tom

Jeston TX1/Nano does not support HDR. You could try to put below configuration in your xorg.conf to see if it can output 10Bit.

Section “Screen”
Identifier “Default Screen”
Monitor “Configured Monitor”
Device “Configured Video Device”
DefaultDepth 30
Modes “1024x768”
EndSection

FYI: Jetson Nano does indeed process HDR content using GStreamer. So my question is if we decode as 10 bits per color can it be displayed at 10 bits output to HDMI and what APIs or player supported 10 bits through the image pipeline. Thanks.

Hi,

So my question is if we decode as 10 bits per color can it be displayed at 10 bits output to HDMI and what APIs or player supported 10 bits through the image pipeline.

You could try to run mmapi sample 08_video_dec_drm as “sudo ./video_dec_drm jellyfish10bit.265 H265 --disable-ui”.

This could support 10bits output on TX2 and Xavier. However, jetson nano/tx1 does not.
