Can't get VDPAU to work

Heey there! I've been working a little to enable VDPAU on several applications, after I learned this would aid my AVCHD editing. I got it to work on mplayer, ffmpeg and mlt, however, not with kdenlive. Under "video drivers" it does not appear (is it would with smplayer). CPU usage is still far above for example playback with mplayer and vdpau.

A few checks (i'm using arch linux):
[daan@arch build]$ ffmpeg -codecs | grep vdpau

I installed svn and git versions from both mlt and kdenlive. Anyone has an idea what i'm missing? Thanks!

I've done some more research, and I discovered that MeLT actually isn't using the VDPAU system. So I was wondering, Could some measure their CPU usage during melt playback? I did the same with smplayer and melt, to discover the difference. This is what I got:

I played a 1080p - AVCHD on my core2duo 2.4ghz macbook pro (early 2008)
-smplayer with xv video output: CPU to 2.4 ghz and usage around 60%
-smplayer with vdpau video output : CPU on 800MHz and usage around 30%

With MeLT you can't really select a video output
-melt CPU to 2.4ghz and usage around 60% (same as xv on smplayer)

So, despite the little melt-vdpau lines posted in my previous message, melt doesn't seem to actually use VDPAU...
Any ideas? thanks!

Wbdsgnr, your tests are flawed. You are testing a program that uses both the decode and presentation portions of VDPAU (smplayer) with a program (melt) that uses only the decode portion of VDPAU. This a huge difference. If you only want to view videos, then use smplayer, not melt, but good luck trying to edit video and apply arbitrary image filters in smplayer while also trying to leverage its VDPAU integration and all of its performance gains.
