Confirm DXVA is working? (1 Viewer)

[gserg]

Is there a way to confirm that I my installation is using DXVA with my ATI HD 4550? Maybe someway in the CCC or in MP itself to confirm that it is actually being used like I think it is? Specifically with MPEG2 HD TV viewing but I guess it would be nice to confirm it with H.264 video files as well.

Thank you for any suggestions

I think the easiest way is to first start your task manager. There is a graph there for cpu utilisation. Start mediaportal and wait a bit. There are a lot of things runnin in the background for the first couple of minutes. Then do a test with h.264 (720p/1080p) file for 10-20 seconds. Exit mediaportal and look at the graph on how high it was. You should see stable cpu levels of 0-10%, it is almost 100% sure using dxva in that case. Ofcourse this is depending on the cpu strength you are using. If its not using dxva you can expect cpu levels of 25-100%, again, dependin on the cpu.

Good luck

....or run MP in windowed mode, play a video, then use GraphStudio (see the link in my sig below) to 'connect to remote graph' -> right click on the video decoder filter -> properties -> output pin - it should say somewhere in the info that it's connected to the renderer using DXVA.

Your right, that is also possible. It used to work like that a long time ago for me. but for some reason its not possible for me anymore to use dxva/codecs/mp windowed mode like that with the same results as fullscreen mode.. Crashes, torn video's or no video at all.... Dont know why though. MP or filter/codec or XP bug.... The way I suggested seems to always works here.

Thank you both. I have used the task manager to watch the CPU usage and my CPU usage is in the 20-40% range when watching HD MPEG2 live TV. But my CPU is probably underpowered by most standards. It is an old Northwood P4 3Ghz.

I will have a look at it with Graph Studio and see what I can see.

Thanks again

That's probably about right on a P4 - my Core2Duo 2.2 GHz runs about 10-20% decoding HD MPEG2 - under Vista neither ATi or nVidia support much in the way of MPEG2 decode acceleration, most of it is done by the CPU (but they support full acceleration for H.264).
