comment:2 Changed 3 years ago by jelluz von plak

I have the same problem for a couple of versions of mpc-hc already. Other players seem to work fine. After using the arrow keys, or skipping forward (or backward) with the mouse multiple times it happens (sometimes).
Pressing stop, going back to the last time stamp and pressing play seems to fix it again for a while.

It occurs in both the 64 bit and 32 bit version.

See added screenshot of the problem in mpc-hc (1.7.3) and the movie being played back fine by another player.

It only seems to happen when DXVA is active.

comment:4 Changed 3 years ago by underground78

What is you video card? Are you using the latest driver? Have you tried other hardware acceleration mode (Options > Internal filters > Video decoder)?

comment:5 Changed 3 years ago by jelluz von plak

I have an intel core i3-550 with integrated graphics and the latest drivers installed (driver updates have been discontinued).
If I disable dxva, everything seems fine. Other hardware acceleration modes that use dxva seem to produce the same result.

Try the latest beta version of MPC-HC just to confirm the bug still happens. If it does, I will put the LAV Filters developer in copy in case he has some thoughts about this.

Any additional information?

What happens if you disable DXVA?

comment:9 Changed 2 years ago by igogo

If I disable Hardware Decoder to use (None), everything seems fine.
One question. Active Decoder field always has the status <inactive>. Is it normal?
DXVA2(native) - Available
Active Decoder: <inactive>

comment:10 Changed 2 years ago by underground78

Can you tell us exactly the version of your video card and of the driver?

If you want to see the active decoder, you have to open LAV Video Decoder options panel through the "Play > Filters" menu during playback.

Another question. After adding a comment i'm getting a

The driver seems quite old, are you sure it's the latest one?

You are right. The latest version is 8.15.10.2993 2/19/2013. I've updated the driver.

comment:15 Changed 2 years ago by underground78

Without any improvements?

comment:16 Changed 2 years ago by igogo

I've reproduce this problem, but much less.

comment:17 Changed 2 years ago by underground78

Could you try the latest beta version of MPC-HC and if the problem is still reproducible upload a sample that can be used to reproduce?

I'm not sure at all we can do something about this, it really feels like a driver issue...

comment:18 Changed 14 months ago by rachman

looks like it happened on interlaced video. I guess it should be fixed with recent nightly with recent lav. there's a fix from lav dev for h264 dxva2 for old intel gpu. at least that kind of video looks better now on my sandy gpu.

It would be great if someone could confirm this.

comment:20 Changed 14 months ago by igogo

This issue is not reproced now on my PC with latest version of MPC-HC. But i have the new GPU now.
