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);
}
