I just made some tests too.
SONY A95L + SONY x800m2:
any DV profile (P7 FEL, P7 MEL, P8, P5): no color space, no color depth, no chroma, RGB
HDR10 (UHD): BT.2020, no color depth (?), 4:2:2 chroma, YUV
SDR (FHD): BT.709, 12bit, 4:4:4 chroma, YUV
So I think BT.2020 shouldn’t be set. Moreover, the color depth should not be set either.
Maybe it’s the 8bit color space combined with the lack of BT.2020 that causes the color saturation problems?
I am having an issue where I get into a boot loop whenever the sd card is inserted into the ugoos. I am trying to boot into coreelec off the sd card. I tried a factory reset and wiped the SD card and tried everything again but it still happens. It boots to the AMLogic splash screen and then just reboots. Does anyone know what may be happening and how to fix it?
It is already updated to Android 0.5.4 :-/. What had happened was that I had been running the 20.4 DV build off the sd card and it had worked. Then I took the sd card out and put 20.5 normal ng generic build on it, and now it’s doing the boot loop. I even tried putting the original 20.4 DV build back on and it’s still not working. It boots into Android just fine, but if the SD card is in, or I have it in a usb adapter in the OTG slot, it does the boot loop :-/. I am not sure why.
I just got my AM6b+ today and got the latest 21.0 nightly installed with the kernel module. I’m seeing dv capability 7 in my dmesg logs but when I try to play a Dolby Vision video the player just stays on the loading circle screen until I back out. Disabling DV or playing a non-DV HDR file works. Trying to switch to player-led DV doesn’t help. Anyone experienced this before?
I might not be related but I did start out installing the latest 20.5 nightly SD card image by mistake but then upgraded via tar file to 21.
Hello. So I am on the 20.5 ng generic build with the Dovi.ko file on the amb6+. FEL works fine, but it appears that Chroma Weight is not working for cm2.9 or cm4.0. Can anyone confirm? Was support for this added in a nightly past 20.5?
It’s running much better. However I did find some FEL titles that have problems skipping chapters, and resuming:
despicable me 2
kindom of the crystal skull
John Wick chapter 4
Menace II Society starts with quarter screen
Midway starts with quarter screen
Scream 3
Spiderman Homecoming
Star Trek First Contact
Star Trek Generations
Star Tre Nemesis
Unbearable Weight of Massive Talent
The Untouchables
These all resume fine without issues for 20.5
@Randy420 What do you mean by “chroma weight”? Never heard of that term, and Google returned no relevant hits…
nice testings! The Sony player is set to Tv led, right?
I did some testing with the latest 20240329 CE 20.5 nightly. Picture in DV movies is good and skipping chapters works, but the sound stops working sometimes or gets broken with strange noises. One example ist lone survivor whrere it happens very often, on 1917 it happens once in a while
This is seems to be a known issue with Amlogic HEVC driver, not having enough dynamic buffers. Not sure if it’s still needed but won’t harm having. Some details are here in this old thread.
Mine is very strange - one time it palys everything perfectly fine, without a single issue and the next time it doesn’t, especially when some friends around and I like to show-off
Just updated to Omega-nightly-20240330 and see what that brings in for me.
