I use haali splitter for mkv's and ffdshow for everything else. Logifuse has advised me a long time ago, that ffdshow can be properly configured so I did and never regretted his advise. All I do for mkv's is just renaming it to avi.

Why do you change mkv to avi? and how does haali pick up the file?

Found an interesting program today called Media player Classic Home Cinema.

This program will play MKV's with proper DXVA. I tested several MKV's today and even during the heaviest scenes the CPU barely reached 10%, awesome.

Problem is, how can I adapt this to work with VMC? You can download the player or the individual filters, but how would you then configure them?

Worth a look anyway

So now we know it's possible. Does it work with 1080P?

Media Player Classic is a phenominal media player, I like it even better than VLC, however I don't believe its possible to replace the VMC media player.

Yes it does!

It's a weird player though, completely self contained. In other words you don't have to install it, you just run the .exe- it's a about 6 meg and contains all the files, filters etc.

So it's not like you can install it and then configure VMC to use it, because you don't install it to run it if you get my drift.

Other problem is, you can't have any other filters between it and your GFX card, ffdshow for instance.

I wish the ffdshow team would hurry up and get DXVA working

from my experienced, for my rig i'm using AMD 64x2 4400+ with 2 Gb memory and Gforce 9600GT. firstly I could not play the transformes 1080p properly due to slow and picture breaking up. later on i donwloaded the Nvidia Pure Video decoder and installed it on my pc. guess what? after that i can watched Transformes 1080p .mkv file with WMP 11 without any problem at all. everything is smooth and flawless..

Don't do this, you risk severly messing up your graphs as you're making the system think you have x264 in an AVI container, when you don't, you have x264 in an MKV container. Fortunately WMP is usually smart enough to properly handle this but there's no guarentee other players, transcoders, etc, will, nor that this "functionality" won't be broken in the future.

You should instead add .MKV to the list of supported media extension types for WMP. Something that you can conveniently do with a single mouse click during the CCCP installation. And yes, CCCP is a codec pack, its a stable and tested FFDshow tryout, Haali and a VobSub if I recall correctly. If you're anal about codec packs you can manually install the component parts. CCCP's chief advantage is that they actually test the various builds included, so you get some guarentee of stability. They also don't perform the kinds of lunacy often found in other crap codec packs such as including multiple codecs for the same video type (ffdshow + native xvid codec for example).

This will most likely NEVER happen. FFDShow is a DirectShow wrapper for the ffmpeg (and similar) codecs. None of the codecs in question are DirectShow aware, and as such, none of them can leverage DxVA acceleration. So basically if DxVA is a dealbreaker for you, you need to look at native DirectShow codecs, FFDShow will never do this for you.

The reason MPC works is because its not using FFDShow, its using (its own?) DirectShow codecs, and thus is quite happily able to do DxVA offload. The issue we have is that the MKV splitter of choice, Haali, is currently unable to properly hand off an x264 stream in most instances to the DxVA-leveraging codecs such as PowerDVD. Once this is fixed, the problem should go away.

Its not so much a case of FFDShow not supporting DxVA being the problem - as there's no reason to expect it to - as much as its a case of the splitter being unable to communicate with the DxVA-aware codecs. So what we really need is a new splitter!

Severus606, thanks for the explanation.

I use the straight ffdshow and haali builds (I used to use the vista codec pack.)

From what you are saying, is it better to use CCCP?

[kiffies]

Does anyone know whether the Gabest splitter would do the trick?
