When using d3d11, subs cannot be rendered

[hooke007]

If selecting the option "use direct3d 11", subs cannot be rendered by the mpc-be's internal sub-renderer. I have to use the xysubfilter instead to show the subtitle in that case.

ps. MPC-BE.1.5.7.6180.x64 MPCVideoRenderer_git_0.5.3.1689_x64

All working perfect. Try reset settings. Show filter list in MPC-BE. What subtitles ?

[hooke007]

MPC-BE 1.5.7.6180 Filters currently loaded:

• MPC Audio Renderer
• MPC Video Renderer
• Audio Switcher
• MPC Video Decoder
• MPC Audio Decoder
• MPC Matroska Source

default setting is OK. But selecting "use direct3d 11" is not OK.

Any kinds of subs.

Try latest version. latest_x64.zip

[hooke007]

No, it doesn't work.

[Aleksoid1978]

Hmm, can’t help. works for everyone except you.

[hooke007]

Hmm..Sorry, I heard the issue from my friends and reproduced it in my PC. (He doesn't know where to post the bug.) Maybe keep it open to see if more people will meet this kind of problem.

Video driver latest ?

[hooke007]

Yes.

[Aleksoid1978]

Here debug build + DbgView. run DbgView, then player, open video with subtitles, close player, save log in DbgView and upload for me. MPCVideoRenderer-0.5.3.1699_git2021.04.08-1c833a0_Debug.zip

Something wrong, can't create shared texture DX9 -> DX11(it use for subtitles render). Some incompatibles.

[hooke007]

I have some findings to help. My device is laptop which have two GPU. when I use the internal monitor. The output was totally controlled by iGPU and it's OK. When I use the external monitor, 2070 control the output. In this case, d3d11 cannot show the subs.

[Aleksoid1978]

We don't have such hardware, can't help.

Maybe wrong interface used in call to OpenSharedResource()? Use D3D9 texture instead of D3D11 texture?

[Aleksoid1978]

No - all is good :)

I don't know the differences about the internal sub-renderer between HC and BE. HC's internal sub-renderer can show the subs.

[Aleksoid1978]

Hm, the same HC/BE.

[Aleksoid1978]

It's Nvidia Optimus. Maybe MPC-HC set to Nvidia but MPC-BE to Intel or auto. Try set MPC-BE as MPC-HC or something else :)

[hooke007]

A good solution. I firstly forced it to run by Nvidia in the driver settings but failed again. So I use the Nvidia Inspector to add the be with hc. It works!
