d3d渲染纹理渲染yuv视频，不能编译shader。

[qq_38289613]

今天用d3d渲染yuv视频时，通过shader将yuv装rgb，但是使用D3DXCompileShaderFromResource编译shader时就是不能通过，也试了D3DXCompileShaderFromFile，都是包类似的错误。哪位大神给指导一下阿，不胜感激。附上代码：
D3DXCompileShaderFromResource(NULL,
LPCWSTR( "sampler YTex;"
"sampler UTex;"
"sampler VTex;"
"struct PS_INPUT{"
"float2 y : TEXCOORD0;"
"float2 u : TEXCOORD1;"
"float2 v : TEXCOORD2;}"
"float4 Main(PS_INPUT input):COLOR0{"
"float y = tex2D(YTex,input.y).r;"
"float u = tex2D(UTex, input.u.xy / 2).r - 0.5f;"
"float v = tex2D(VTex,input.v.xy / 2).r - 0.5f;"
"float r = y + 1.14f * v;"
"float g = y - 0.394f * u - 0.581f * v;"
"float b = y + 2.03f * u;"
"return float4(r,g,b, 1);}"),
0,
0,
"Main",
"ps_2_0",
D3DXSHADER_USE_LEGACY_D3DX9_31_DLL ,
&shader,
&errorBuffer,
&MultiTexCT
);

也试了这个：
ret=D3DXCompileShaderFromFile(
(LPCWSTR)("shader.txt"),
0,
0,
"Main", // entry point function name
"ps_2_0",
D3DXSHADER_DEBUG,
&shader,
&errorBuffer,
&MultiTexCT);
报错：error:error X1512: failed to open resource
GetLastError() 返回1813.
我是在虚拟机上用qt开发的。
