Hi,
Been using for approximately a year without problems, but something has changed recently that is causing troubles with 4K HEVC HDR playback. 1080p content is fine. I'm getting visual artifacts on the right side of the screen. It's weird, because everything was working perfectly all this time until the playback issue popped up, and I have not touched anything in the settings or setup.
I've found that it only affects MrMC. Netflix and Amazon are both fine for 4K HDR. And I've further found that it appears to be related to acceleration in that the artifacts disappear when I turn VideoToolbox on (though when I do that, the colors look like poo). I've also tested the same file in VLC, and it worked fine.
Something appears to be specific to acceleration in MrMC. But if that's the case, I can't figure out why nobody else appears to be complaining...
For troubleshooting, I've swapped HDMI cables, and HDMI ports. Hard reboots of TV and the ATV.
Pastebin of the mediainfo is here - https://pastebin.com/aFP2i3Dy
Debug log is U9OPH, uploaded moments ago.
Sample video of the artifacts is here - https://ufile.io/s53poysi
AppleTV 4K tvOS 13.3
HDMI direct to TV (no AVR in the path)
MrMC 3.9.2
LG OLED C7 (latest fw, 05.80.50)
Any help is appreciated.
1. No user installed addons are supported, python or otherwise.
2. No, they really are not supported.
3. They are not coming back
4. Read from 1. again

Re: New issues - Visual artifacts when playing HEVC 4K HDR
The behavior is consistent across all of the files in my library, but here's a clip from the same video as my OP.

Sample plays fine with avf codec, no artifacts seen.

Re: New issues - Visual artifacts when playing HEVC 4K HDR
So is this looking like a hardware issue then?
Behavior stopped for a bit without me making any changes, but has started up again tonight. As with before, whatever is causing it seems exclusive to MrMC, and to HEVC/4K. A bit maddening.

At this point MRMC will not decode any HDR content on my Apple TV. just looks washed out no color.

Please start a new thread, your issue has nothing to do with topic.xkwwwx wrote: 29 Dec 2019, 14:35 At this point MRMC will not decode any HDR content on my Apple TV. just looks washed out no color.
