Fwd: MPlayer direct3d video output driver under Windows XP

[Tanguy Krotoff]

Hello

If you have some time, the best is to get in touch with Georgi Petrov,
the developer of the direct3d driver and try to help him to fix it.

Here is a copy of our conversation and its mail address.

Meanwhile I integrate your patch

Hi,

I'm happy you point out these problems. Of course I'll do everything
possible to help you fix them.

I'll have a trip to Germany this week between Wednesday and Sunday and
I won't be able to reply or provide any help during this period, but
in the beginning of the next week, I'll look into the problem and help
fixing it.

The Direct3D driver is written to be agnostic of particular Windows
version and it should work the same way under Windows 98 - Windows 7
in case they have Direct3D 9 runtime installed and video card with D3D
support + suitable drivers is present. Of course this is sometimes too
good to be true ;)

Can you please provide the following information:
* which Direct3D runtime is installed (earlier Windows before SP1 or
SP2 for example come with Direct3D 8.1, but I may be wrong)
* What is the video card
* Does the video card use the Microsoft provided display driver with
Windows (still vendor-specific) or a newer vendor driver is installed?
And what version.

I'll help you work out the problems. Some older video cards don't
support Direct3D unfortunately. I ran across at least 2 laptops, which
weren't able to expose enough features to the D3D API layer in order
to use them for playback purposes. Otherwise they did appear to
"support" D3D :(

I can reply until tomorrow evening. Please, feel free to ask more questions!

I forgot - I need the MPLayer SVN version you use (as older ones
contain broken versions of the driver), as well as full output when
run with "-v" option. Thanks.
