# vulkanshaderspv

Vulkan image shader filter.

## Examples

    gst-launch-1.0 videotestsrc ! vulkanupload ! vulkanshaderspv fragment-location="myshader.f.spv" ! vulkansink

The following is a simple Vulkan passthrough shader with the required inputs. Compile it with `glslc --target-env=vulkan1.0 myshader.frag -o myshader.f.spv`.

    #version 450

    layout(location = 0) in vec2 inTexCoord;

    layout(set = 0, binding = 0) uniform ShaderFilter {
      float time;
      float width;
      float height;
    };
    layout(set = 0, binding = 1) uniform sampler2D inTexture;

    layout(location = 0) out vec4 outColor;

    void main () {
      outColor = texture (inTexture, inTexCoord);
    }
