[TESTING] Linux 4.9 kernel and improved video stack for Vero 4K / 4K +

I’m having a problem where movies I have that are rips of 4K discs seem muddy/dim compared to rips of standard Bluray discs. My TV is an older Vizio with a Vizio soundbar between the TV and the Vero 4K+. I’ve tried direct into the TV, and it might be a hair better, but not much. If I turn off amcodec acceleration the problem seems to go away, but of course the Vero 4K+ can’t deal with the 4K video anymore. I’m including 2 sets of logs (first it with the soundbar attached, second is direct through the TV). I’m also attaching a couple pics I snapped. If you look at the “white” text color you’ll see the difference (the amcodec one the text is basically gray instead of white. For the logs, I was watching Shazam! (in case you didn’t look at the pictures).

BTW, I did try forcing the Vero4K+ to send HDR (I guess instead of converting it to something else), mostly because someone else mentioned trying that for an issue that seemed like it might be similar.

sudo nano /sys/class/amhdmitx/amhdmitx0/force_hdr

Had no affect for me.
