MPC-HC + madVR freeze in x264 fullscreen

[Rhino Cracker]

Hi all,

I have a problem using one of the latest builds of madVR and MPC HC.

While madVR does a great job in making 2160p HDR h/x265 material watchable after setting the chroma upsampling to Bilinear

and MPC-HC was doing a good job in displaying 1080p SDR h/x264 material with the default evr custom renderer for years

for some reason my video freezes when I enter fullscreen and try to watch anything encoded in h/x264 with madVR selected in MPC-HC.

Combinations I've tested:
- 1080P SDR h264: doesn't work
- 1080p SDR x264: doesn't work
- 1080p SDR x265: works
- 1080p HDR x265: works
- 2160p SDR h264: doesn't work
- 2160p SDR h265: works
- 2160p HDR x265: works
So for this moment, I see a clear correlation between h/x264/5 and working/notWorking.


I would like to use madVR for more than just 2160p HDR, because:
- I'm too lazy to switch renderers and restart MPC-HC before every video
- madVR helps me to use the full color range abilities of my TV, which looks like is from 10-12 to 245-250, when I set Windows color output format to Full-RGB.
Without the custom color range feature of madVR, I either have to boost every black value to (16,16,16), which is rather grey + never reach max white, or I have to loose all details <(13,13,13) as black and get a slight over saturation / white clipping.

So, I'm also thankful for any adjustment tips to better use the color space of my TV, either only in MPC-HC or in whole windows. But this topic's primary goal is to make madVR running without a freeze.


Here are the details of my setup:
- MPC-HC x64 2.3.5 from girhub: https://github.com/clsid2/mpc-hc/releases
- madVR v0.92.17 from here: https://forum.doom9.org/showthread.php?t=146228
- My machine is a Zotac ZBOX CI337 with a passively cooled Intel N100 inside
(supported hardware video decoders should be listed here in column "Alder Lake")
- Screen: Samsung 50" 1080p SDR Plasma TV PS50B530S2W
