Hey guys, I have a question about mpv

When using mpv on Windows (no bully pls) and choosing hardware decoding, what is the difference between
Using hardware decoding (dxva2-copy).
VO: [opengl-hq] 1280x720 nv12

and
Using hardware decoding (dxva2).
VO: [opengl-hq] 1280x720 dxva2_vld


Is either of these backends significantly better than the other, or are they about the same?
>>
pls respond

There is no difference

You could have just opened the manual and searched for it.

Most video filters will not work with hardware decoding as they are primarily implemented on the CPU.
Some exceptions are vdpaupp, vdpaurb and vavpp. See VIDEO FILTERS for more details.

The vaapi-copy and dxva2-copy modes allow you to use hardware decoding with any VO, backend or filter.
Because these copy the decoded video back to system RAM, they're likely less efficient than the vaapi
or dxva2 modes respectivley.

That makes sense, thanks

I'll read the manual in a little bit, but just to clarify, are you saying that dxva2 will play video more CPU-efficiently than dxva2-copy?
>>
>>53836241
If you need to use a VO or filter that is incompatible with dxva2, then use dxva2-copy, and if you don't then just use dxva2.

>dxva2 will play video more efficiently than dxva2-copy?

Yes.

i dled mpv to open my webM

how do i configure it so it's always silent and also auto-repeats by default.. and also open a new instance every time i open a webM.. on windows

Alright, thank you for the help.

I just have one more question that isn't covered in depth in the manual:

The manual says that in order to use dxva2, I must set the vo backend to either "angle" or "dxinterop". The manual then says that "dxinterop" is experimental, but it doesn't say much about which one is more efficient. Here is the relevant manual section:

>angle
>Direct3D11 through the OpenGL ES translation layer ANGLE. This supports almost everything the win backend does, except ICC profiles, and the nnedi3 prescaler.

>dxinterop (experimental)
>Win32, using WGL for rendering and Direct3D 9Ex for presentation. Works on Nvidia and AMD. Newer Intel chips with the latest drivers may also work.

Which one do you think would be better to use overall? A previous mpv general thread had dxinterop listed in the recommended configurations, but I just want to be sure about the better one.

>>53836402
You shouldn't even use DXVA2 or any GPU decoding.
>>
I just installed this on linux and I for some reason I can't find the .config file or the .mpv folder, anyone know where could it be? Or i need to create them?
>>

>>53836402
use dxinterop
>>
>>53837594
You need to create ~/.config/mpv/mpv.conf
