Represents a GLSL shader program.

After constructing a program, keep a reference for its lifetime and call delete() (or release the current GL context) when it's no longer needed.

Deprecated.

Compiles a GL shader program from vertex and fragment shader GLSL GLES20 code. Parameters:context - The Context.vertexShaderFilePath - The path to a vertex shader program.fragmentShaderFilePath - The path to a fragment shader program.Throws:IOException - When failing to read shader files.GlUtil.GlException

GlProgram

public GlProgram([String](https://developer.android.com/reference/java/lang/String.html "class or interface in java.lang")vertexShaderGlsl,[String](https://developer.android.com/reference/java/lang/String.html "class or interface in java.lang")fragmentShaderGlsl)
          throws[GlUtil.GlException](GlUtil.GlException.html "class in com.google.android.exoplayer2.util")

Deprecated.

Creates a GL shader program from vertex and fragment shader GLSL GLES20 code.

This involves slow steps, like compiling, linking, and switching the GL program, so do not call this in fast rendering loops.

Parameters:vertexShaderGlsl - The vertex shader program.fragmentShaderGlsl - The fragment shader program.Throws:GlUtil.GlException
