10-bit Output on NVIDIA is still disabled 10.9.5

Post by Morku on Thu Jan 15, 2015 9:40 pm

Hi,
the new version of k-lite forced me to make a new clean install of k-lite, so I did. The previous version was uninstalled and the checkbox "Reset all settings to their defaults" was enabled.
After installation the options of 10-bit Output in LAV Video Decoder was disabled (and some others). You can see on that picture:



On another PC with AMD graphic card, the settings was okay by default.
I know about the NVIDIA 344.11 driver bug, but this was fixed with the following driver version. My PC runs NVIDIA driver version 374.09 and is not affected of that bug (GTX 480) (and yes, during installation of k-lite, driver version 374.09 was already on pc)
So what can be the reason? Maybe you can have a look.
Thanks!

It is actually still partially broken in 374.09. They fixed the problem for EVR, but it still fails with some of the other renderers such as VMR-7, which other applications may use since it is a default renderer in Windows.

Okay, thank you. Hopefully NVIDIA will fix it finally, because in future I want get rid of AMD.
Luckily, my GTX480 seems not to be affected of my 10-bit material.

Hi, while on the subject, I also have an nVidia GPU (GTX 970) with the latest (374.09) drivers installed.

I play almost all video formats through MPC-HC (x86) and use the madVR renderer. Which 10-bit modes should I enable? (does it really make a difference? I have some anime videos which were encoded in 10-bit)

And those 4:4:4 modes, are they supposed to be disabled? How do I know if I should also check those options?

Sorry if I'm asking too many questions, it's just that you are so helpful, and your codec pack is simply the best! I learned A LOT about media playback on Windows with the readme files, they're really thorough and very clear!

Anyways, thank you so much ever and ever! :-)

You can enable all 10-bit and 16-bit colorspaces.

I found out on another PC with Intel 4400 HD graphics (it's a NUC D34010WYK), my 10-bit movies doesn't start. The MPC-HC opens, but the window stays black.
So I tested again in LAV Video and after uncheck P016 in 16-bit, the video starts. This problem didn't happen on previous k-lite. Maybe it's because of the new driver version 15.36.14.4080, who knows. But I wont see this PC all day, so I can't test around. Until my next encounter this option will help.
I used Enhanced Video Renderer.

It is a bug in that version of the Intel driver. It makes the renderer accept P016 input, but it does not actually support it (correctly).
