Tearing with 1080p, vmr9 and ffdshow. Please help

[mces97]

I've posted this on many forums with not a lot of results. I own an ati 4550. Up until recently everything worked as I needed it to. The problem's started when I uninstalled ffdshow to upgrade to a newer version. After doing that whenever I play videos and use ffdshow as the decoder and vmr9 as the renderer I get tearing in 1080p x.264 mkv files. I also have lost the ability when I click use application settings in the video settings of catalyst control center to use the color controls in zoom player, and the sliders in the overlay option in ffdshow no longer move, so I believe that is why the color controls do not work in zoomplayer. I have tried everything from uninstalilng ffdshow and putting back the older version, uninstalling ati drivers and ccc, plus using driver cleaner to make sure all ati drivers are gone and using different versions of the drivers. I even did a fresh install of windows to have the same problem come up. I am using windows xp still on this pc as for my needs still works fine. I am waiting for an ati 5550 to be delivered which has 320 stream processing units, as opposed to 80 on the card I have now. Not sure exactly if this will fix my problem, but does anyone have any other suggestions as to how to fix this. I do not want to use the overlay renderer but for now I have no choice. Thanks

What version of Windows?

[mces97]

I am using windows xp with service pack 2. I might try updating to service pack 3, however like I stated in the previous post, everything should technically work as it had worked before, so I can not figure out what might be stopping it from working. I don't think it is ffdshow as I configured another system with the same versions of ffdshow, haali media splitter and zoomplayer, and that system works fine, the only difference is that system has an nvidia card. I know vmr9 is more susceptible to tearing, but it should work.

You could try get FFDShow output a different colorspace, but honestly I don't know.

It is very strange. It only happens on 1080p videos. 720p is fine, so I don't think it would be the colorspace. Plus it does not happen if I choose the cyberlink h.264 decoder. It does happen though if I make my output on the videocard 1080p 24hz with cyberlink. I am going to do another fresh install when I get the new card, I should be able to get it to work.

what kind of processor do you have? is't it frame drops and not tearing since it happens only to higher resolutions movies?

Try MadVR ;) Feels good, man!

Your Radeon 4550 is more than capable of decoding 1080p H.264 in real-time. In fact, upgrading to a 5550 will probably make little to no difference, since it's not the stream processors that do the decoding, but rather an ASIC whose sole lot in life is to decode H.264, VC-1, and MPEG-2! The stream processors can help deinterlace, but not decode. Your issue lies in successfully presenting this video. The causes of these issues are very tough to troubleshoot.

I never had tearing / jitter issues until I bought a 50" plasma TV, at which point even EVR-CP was unbearably bad on my system (nVidia GTX 460 and a Core 2 Quad on Windows 7). MadVR fixed all these issues, out of the box - hence my suggestion :devil:!! Good luck!

Use VMR7w renderer, DXVA and set display refrash rate matched to video fps. IMO Win7 has faster video rendering than XP. Also try D3D setting for VMR9r.

If you are using Mpc-Hc, check the GPU control settings under View>Renderer Settings>GPU Control. Sometimes enabling all three options can solve a lot of tearing issues although as mentioned MadVR tends to fix it and improve output quality significantly.

Turn on vsync in the ATI control panel, or force it on.
