Update: SUCCESS tv-led dv only any device !
The catch: Currently only at a proof-of-concept stage / first triggering of the DV mode on the TV.
How to replicate:
- Install this build. This was built on 20.5 NG, no idea if it would work with 21.
- Set CoreELEC to 1080p 8-bit RGB output and change the refresh rate to trigger the changed mode. This will mess up the colors of some/most content - it is expected they appear all pinkish.
- Play test_pattern_yuv_as_rgb.mkv
- Pause the video, this is required (
not strictly needed - but easier as the video is short). Do NOT have the OSD / giu showing at all or let CoreELEC dim. - With the test pattern showing, trigger tv-led DV mode with:
echo DV_enable > /sys/devices/virtual/amhdmitx/amhdmitx0/attr
- Should now be in tv-led DV mode. Colors of the picture will have changed and the tick should now only be in the top DV box of the image.
Note: bringing up the gui / letting CoreELEC dim the screen / anything but keeping the video showing will cause the DV mode to stop.
