What's the point with DXVA? (1 Viewer)

What is the purpose of enabling DXVA since watching DVD movies with it turned on gets useless for non-english speaking people?

You do not get any subtitles and you do not get any working menus. And as I understand it DXVA does not allow any filters to add anything more to the decoded video. This hardware acceleration tends to suck IMHO.

I assume it will be the same for subtitles in DVB broadcasts?

With normal DVD MPEG2 I guess you can live with it since it does not take too much CPU power to decode but when you watch HDTV MPEG2 or even the harder H.264 where you really need/want DXVA to be enabled it gets useless?!

Can anyone explain why there is this limitation of DXVA and if there are anything you can do about it.

Your graphics card must support DXVA and from what I have read it is intended for HDTV, which until it starts being transmitted one way or the other, no one will notice the difference.

ps DVD's are not High definition again no difference, it's a future thing.

So might as well disable it?

Well my graphic card support DXVA for mpeg2.

Mediaportal CPU workload drops from 25-30% to 5-10% for normal DVD movies with DXVA activated.

So for DVD I can live without DXVA but when HDTV with H.264 is a reality I really want to get get a graphic card with H.264 hardware decoder and use DXVA with subtitles.

So this is my question really. Can I get subtitles and still use DXVA?

DxVA is NOT only for HDTV, it's a general DirectX acceleration for video related stuff. I guess that's why it's called "DirectX Video Acceleration". :wink:

DVB subtitles are not implemented yet, so the discussion about DVB subtitles & DxVA is pointless at the moment. We'll see when that feature is in, you cannot predict non written code. :wink:
