Edges of the picture being duplicated on the opposite edge when playing back video

Lum · 2008-11-17, 22:27

I'm sure this must have been asked before, but I can't find anything by searching, probably using the wrong search terms or something.

Basically what I'm getting is a single pixel border around the image when I play back any AVI, MKV etc. file. It appears that the rightmost row of pixels is either getting copied, to the leftmost edge (and vice versa), or it is being swapped. This also affects the top and bottom of the image.

It doesn't seem to be tied to any specific codec, I tried switching from the built-in MPV codec to FFDShow and it made no difference, it also affects H.264 files that get decoded with CoreAVC. It doesn't affect BluRay discs that I playback through PowerDVD.

This is quite annoying because if one side of the image is significantly brighter for a particular scene, you get an obvious line down the opposite edge.

If I had to take a guess I would guess it was something to do with MP rendering the video to a D3D or OGL texture, and it's trying to tessellate that texture, but this is purely a guess, I have no idea how MP is written.

This affected me in RC2 and is still affecting me in RC3

I second that. Seeing it all the time now on my new 52" screen.

Doesn't happen in MPC-HC

ATI HD 3200 onboard here.

Bump in hope of a solution?

I solved it by installing the 8.11 drivers for gpu & chipset.

Lum · 2008-12-20, 06:42

Thanks for that. Installed 8.12 and that sorted it. Installed RC4 too, since they snuck that one out while I wasn't looking.

I have this also. HD3200 onboard, Catalyst 8.11 and 8.12. And only in the bottom of picture have a small stripe of the top of the picture (mkv or xvid files only).
