Unable to speed up x5 the 4k VP9 video about videorenderer HOT 12 CLOSED

The hardware decoder has a decoding speed limit. This limit is different on different decoders. Also, part of the power is taken by the output to the screen.

In my measurements on an Intel UHD 750, the HEVC 8-bit decoder is faster than the VP9 8-bit decoder.
For fast operation of integrated graphics, fast RAM operating in dual-channel mode is required.

What player use ?

The video renderer has nothing to do with changing the playback speed.
I checked in MPC-BE - everything is fine.

Hardware decoder maybe too slow?

This is a problem with your hardware that you didn't mention.

Also, if you press Ctrl+J, you will get additional information.

Not sure what do you mean by player. I use MPC-BE with MPC Video Renderer & MPC Audio Renderer.

Maybe. VLC speeds up vp09 fine though. Maybe some option breaks vp09 in MPC-BE.

Thanks, that's test with x5 speed:

Frame rate 120, working.

It's not x5, i took this speed just to illustrate the problem. Usually this starts happening at about x1.7. What happens is that after some speed Sync offset is no longer dropping towards zero, but increases, increasing difference between audio and video. This means that this program reaches it's maximum framerate (bitrate?) for the video and can't process it any faster, while audio doesn't care and speeds up to any number.

Is it the only solution: to upgrade hardware? Can anything be done via program part?

from videorenderer.

Yes, your hardware is too weak.

It would be better though, that if vp09 video can't reach desired speed it would lag and stutter rather than running video slower than needed. This way desync would be immediately noticable.
