The playback is running on CPU only with the latest MPC-VR

[Victor-Freeze]

MPC Video Renderer 0.7.3.2210 has lost the ability to play video using GPU — video playback is always running on the CPU when the video player is using MPC VR as a video renderer.

The video player tested is MPC-HC 2.1.6, video codec h.265.

There is no such problem with other video renderers.

Change hardware decoder to D3D11. MPC-HC options > Internal Filters > Video Decoder

I did. It doesn't help. Previously, it worked fine with GPU playback.

Run the video. While running it, go to the taskbar icons (where the language and clock is). open the red Lav icon, and there, in hardware decoder to use, make sure to pick D3D11

Also, @clsid2, for some reason the internal Lav filters are inactive while I'm using MPCVR, the external one is the one which counts (the internal one shows inactive, while the external one shows it works as it should). Maybe its something with the K-lite package, that counts it as external? Regardless, seems like at least for me, hardware playback works fine with MPCVR

Thanks! It did the trick! You can access internal LAV filters as shown in the screenshot:

[Victor-Freeze]

The issue can now be closed. I'm sorry for any trouble caused. @NBruderman Thank you so much!

[NBruderman]

No problems! But that's actually raising an interesting question... why the external filters are being chosen over the internal ones... Anyway, @Victor-Freeze, you can close the issue yourself, just mark it as completed

If you mark the external filter as "Prefer" - the MPC-HC will be using the external one, instead of internal.

0.7.1.2172 - 2023-12-25
------------------------
The DXVA2 decoder is no longer supported in DirectX 11 mode.

I recommend using the MPC-BE player. The built-in MPC Video Decoder with default settings will use the first available D3D11, DXVA2 or software decoder.

External filters list should be EMPTY !!!!

Stop doing dumb things.

My external filter is empty, and for some reason it still default to the external lav. Maybe it's related to K lite installation? After all, it installs the regular MPCVR, not the fork.

[clsid2]

K-Lite uses internal LAV by default. You should update and do a fresh install.

Can confirm a fresh install fixed the issue
