SkiaSharp - Optimal use of runtime effects
Hi! I have a video player that renders the video frames with a custom
I have a
The problem I am having is that this shader seems to need a rebuild for every new image frame, because of how the SKSL pipeline works -- "textures" are abstracted as another shader that needs to be chained before my custom shader. So the code to do this looks something like this right now:
The
My questions:
- Where the heck is the documentation for SKSL? I believe the solution I came up with is sub-optimal just because I can't find documentation and had to trial-and-error to get this to work at all.
- In GLSL you would normally use a special kind of shader variable for textures which allows rebinding the texture without needing to recompile the shader just to change the image it uses. SKSL does not seem to have this capability because they have modelled textures as "shaders" in their pipeline and so textures have to be comverted to shaders before being inserted in the pipeline. Why does it work this way? Did I miss an API in skia(sharp) that allows me to re-bind the image without rebuilding the shader?
