These are software-emulated "shaders" that are used to initialize custom lookup textures. The shader can then do whatever it wants to the backbuffer, using multiple passes if necessary.Īs documented in the help file, there is support for texture shaders to pre-initialize textures. Once a technique is selected, VirtualDub uses it to render a single quad on screen with the source image bound as a texture. These techniques do not have to actually implement those filtering modes this is simply a convenient hack to allow three different sets of shaders to be used. The effect file can supply up to three techniques, which are bound to the point, bilinear, and bicubic filtering modes on the context menu (right-click menu) of the display panes. Effect compilation is very fast so this is much less of a problem than you might think. fx file every time it gains focus, so iterating on a shader simply requires that you task switch to your editor, save the file, and task switch back. In addition, VirtualDub will reparse and recompile the. This makes them very flexible and powerful. The format of these files is documented in the Microsoft DirectX SDK documentation they allow vertex shaders, pixel shaders, and multiple passes to be defined. The video shader support makes use of the D3DX effect system, which means that it takes standard. Some of you will already have it, as I think it's installed by some popular games.

The distribution doesn't include the D3DX DLL for various reasons, but there is a link in the help file to download the installer from Microsoft. It dynamically links to D3DX so that the DLL is only required if you are using the video shader support. VirtualDub 1.6.11 uses d3dx9_25.dll, which is used by the April 2005 SDK. From what I gather, this is becoming quite a mess, because applications are forced to start the DirectX installer in their setup process, and lots of people are canceling it because they think they already have DirectX 9.0c installed, only to find that the application doesn't start because of a cryptic link error on the missing D3DX library.
#VIRTUALDUB WARPSHARP UPDATE#
I don't know about other ISVs, but personally, I like to ship applications in as few locally-contained files as possible and for them to never change unless I explicitly update them. Supposedly, part of the reasoning behind this is that it allows Microsoft to update a D3DX version after the fact if it happens to contain a security flaw. So, basically, the D3DX DLLs are treated as system DLLs, but they don't come with the OS or any patches to the OS, and every application is supposed to include one, even though it's often bigger than the application that uses it. Didn't modify the DirectXSetup installer UI between SDK versions, so it still says it's installing DirectX 9.0c even if it's installing a D3DX DLL you don't have.

To activate custom video shader mode, select Options > Preferences from the menu, jump to Display, then enable DirectX, Direct3D, and effect support. This makes GPU shaders attractive also for rapid prototyping, which I hope is what the new shader support in 1.6.11 will enable.

More importantly, though, it is easier to quickly write an optimized shader than to write an optimized software filter.

GPUs are great for massive image manipulation (unless you happen to have one with "Extreme" in the name), and thus it's only natural that they'd be useful for video.

As I said in the previous blog entry, one of the new features in 1.6.11 is the ability to bind custom vertex and pixel shaders to a video display pane.
