[PATCH] Direct3D GUI rendering and video playback broken

Description

On Windows, MythTV has settings to select Direct3D as the current video renderer and the paint engine. Unfortunately, both options are broken on my Win32 systems (Win2k and WinXP with Nvidia GTS 2 Pro graphics) and also with Wine 1.3.6 and VirtualBox 3.2.10. The attached patch enables GUI painting and video on all these systems except VirtualBox (Direct3D driver issue).

Severity and priority are to be set during triage. See the TicketHowTo.

Are you saying these patches are to make the Direct3D 9 code support a GeForce 2 GTS, a 10yr old card only capable of DirectX 7?

comment:2 by Lawrence Rust <lvr@…>, 15 years ago

No, this patch enables any DirectX 9 capable graphics to work with Myth, including Wine. Currently the code fails to work with cards that don't support YV12 surfaces and A8R8G8B8 back buffers.

Just 'cos a card is 10 years old doesn't mean that it shouldn't work with DirectX9. If programmed correctly, DirectX gracefully degrades into software emulation of missing functionality. This patch enables graceful fallback.
