video stop after black screen ans after a few seconds it accelerates / Ryzen / x265

On win7 or 10, when I'm watching a film. At the beginning it's ok and after a balck screen, sounds continue but video is on 'pause' and after a few seconds, the video accelerate until it synchronizes with sound... And it does that all the movie. I've the last standard version of k-lite. I use LAV-madVR. It does that apparently on MKV with x265 codec.

I pressent a bug with my new hardware..
I've a GTX980 and now a RYZEN 1700 on ASUS-X370 chipset (up to date).

But when I use VLC I've not this problem (but some problems with subtitles it's why I prefer using mpc with k-lite)
Anyone has this type of problem? Or an idea of its origin?

Thank you!

Test if playback is good when using "Enhanced Video Renderer (Custom Presenter)" instead of MadVR. If it is, then you need to adjust MadVR settings.

If it also happens with EVR, then adjust hardware acceleration settings in LAV Video decoder. Your GTX980 only has partial acceleration for HEVC/H.265. Try all available options and test which one performs best in your case.

Hi @Admin, can you please show us step by step and slowly in details on how to carefully setup these settings for x265 videos can not be reproduced with the latest version of Klite mega from MPC HC x64. thanks

It should already play with default settings.

If you have a problem then you need to provide details about your CPU and graphics card. Your system might not be capable of playing high resolution x265 videos.

ok sorry here are details below please note that km and some other players play x265 flawlessly with no errors & no juddering whatsoever .latest codecs klite mega installed latest mp hc x64
CPU i5 m430 2.27mhz
graph nvidia geforce 330m
RAM 4gb
win exp index 5.9
os win 7 x64

Your GPU does not support HEVC, so there is no hardware acceleration. Your CPU should be able to handle 720p video and maybe even 1080p.

What is the CPU usage with kmplayer?

all 1080p videos have been reproduced perfectly up until the moment i noticed it would not render h265. say how do i check the cpu usage with km player while reproducing HEVC? i find it unusual and not logical thatt km plays it perfectly whereas mpc hc simply doesn't reproduce video content but solely audio.

If you don't get any video at all, then it could be a splitter problem.

MPC-HC menu > Play > Filters
You should see LAV Splitter in the list. You should not use Haali splitter because that does not support HEVC.

that makes sense. sir could you be much more specific "you should see LAV filter in the list" ok and then? namely there are at least five drop down menus when i get to the splitter. attached are printscreens.

1) Run the codec pack installer
2) Uncheck "Perform quick upgrade"
3) On the "Select Components" page scroll down to the "DirectShow source filters" section. Change Matroska/MP4/MPEG-TS choice to LAV.

thank you for your swift replies. i gather the problem has been solved by checking exactly all lav boxes. the only thing i didn't touch is the dialogue upon installation pertaining to software decoding. what do you suggest me and all users to select. thanks once again for your support

Use either software decoding or DXVA2 native. Your GPU only supports hardware acceleration for H.264.
