MPC-HC no DXVA

Post by Lite on Wed Sep 19, 2018 4:53 pm

Have Win 10 x64 and GeForce GTS 250
While BSplayer run all video in LAV dxva2n, MPC-HC runs in DXVA just some small part of my videos and other videos in software mode.

DXVA2 (Native) -> OK
Active Decoder: avcodec
What's wrong with MPC-HC?

Make sure you are using the internal subtitle renderer of MPC-HC. If VSFilter is used for subtitles, then dxva2n will disactivate. There must be a direct connection between video decoder and renderer.

OK. It's working. Needs to be: EVR custom presenter + internal subtitle renderer.
And how to disable frame drop? I need to see pure performance.

For benchmarking performance you should use DXVA Checker tool.

Thank you.
It's bad that applications began to make unconfigurable - for idiots.
In LAV filters, you can not configure deblocking. FFDShow and CoreAVC had deblock settings.
In MPC-HC you can not turn off frame skipping. In BSplayer frame skipping are configurable and disabled by default. I love BSplayer.

Deblocking is a required step in the H.264 decoding process. Skipping that will lower quality. Those old decoders just offered it as a dirty hack to make things work on very old computers.

Mega still offers the option to use ffdshow for H.264 so if you really need it you can use it. Skipping deblocking is only relevant when doing software decoding.

Your GPU should support H.264 through DXVA. So playback should be smooth. Perhaps preformance problems are because of something else, like animated subtitles.
