Blur a samplerExternalOES texture in a fragment shader

I'm running a video on a OpenGL texture and applying multiple image filters to it using a fragment shader.

Code snippet from the shader:

 private static final String fragmentShaderCode =
        "#extension GL_OES_EGL_image_external : require\n" +
        "precision mediump float;" +
        "uniform samplerExternalOES texture;" +
        "varying vec2 v_TexCoordinate;" +
...

I'd like to also blur this, but I only found examples to blur a sampler2D texture, not a samplerExternalOES one.

Is it possible to convert from one to the other? Or how would that work?

You can use this same as sampler2D. You can access texture using texture2D function itself. Apply your blurr filter as if it was a normal texture. It should work.
