Distorted image when seeking in a H264 video

Post by hax on Fri Aug 10, 2012 10:56 am

Hello.
I was wondering why I got this weird distorted images while seeking in a video in Windows Media Player on Windows 7.
I did only recognize this in H264 (MP4) videos. Here's a screenshot: Example 1 Example 2
I was using no codec pack so far, but now I tried this K-Lite codec pack. Tried to change to a different DirectShow filter but when using LAV or ffdshow the problem still exists. When seeking in the video I get this distorted image for 1-2 seconds and then everything is fine again.
When I use VLC Player to watch the same video there is no such problem.
I don't know what to do :/

WMP12 uses Media Foundation for playback of MP4 files. You can disable Media Foundation with the Win7DSFilterTweaker tool. Then it will use the decoder from the pack.

Test the file in the GraphStudio tool.

Change the LAV Video Hardware Acceleration setting to DXVA2 (copy-back) if you need the hardware acceleration, software rendering should be fine.

I haven't checked but I think in K-lite 9.3.2 it's already fixed.

I've tried that already and it doesn't make any difference.
Recently I reinstalled Windows which solved the problem.
