Method Detail

• isProtectedContentExtensionSupported

  public static boolean isProtectedContentExtensionSupported​(Context context)

  Returns whether creating a GL context with "EGL_EXT_protected_content" is possible. If true, the device supports a protected output path for DRM content when using GL.

• isSurfacelessContextExtensionSupported

  public static boolean isSurfacelessContextExtensionSupported()

  Returns whether creating a GL context with "EGL_KHR_surfaceless_context" is possible.

• checkGlError

  public static void checkGlError()

  If there is an OpenGl error, logs the error and if ExoPlayerLibraryInfo.GL_ASSERTIONS_ENABLED is true throws a RuntimeException.

• compileProgram

  public static int compileProgram​(String[] vertexCode,
                                   String[] fragmentCode)

  Builds a GL shader program from vertex and fragment shader code.

  Parameters:

  vertexCode - GLES20 vertex shader program as arrays of strings. Strings are joined by adding a new line character in between each of them.

  fragmentCode - GLES20 fragment shader program as arrays of strings. Strings are joined by adding a new line character in between each of them.

  Returns:

  GLES20 program id.

• compileProgram

  public static int compileProgram​(String vertexCode,
                                   String fragmentCode)

  Builds a GL shader program from vertex and fragment shader code.

  Parameters:

  vertexCode - GLES20 vertex shader program.

  fragmentCode - GLES20 fragment shader program.

  Returns:

  GLES20 program id.

• getAttributes

  public static GlUtil.Attribute[] getAttributes​(int program)

  Returns the GlUtil.Attributes in the specified program.

• getUniforms

  public static GlUtil.Uniform[] getUniforms​(int program)

  Returns the GlUtil.Uniforms in the specified program.

• createBuffer

  public static FloatBuffer createBuffer​(float[] data)

  Allocates a FloatBuffer with the given data.

  Parameters:

  data - Used to initialize the new buffer.

• createBuffer

  public static FloatBuffer createBuffer​(int capacity)

  Allocates a FloatBuffer.

  Parameters:

  capacity - The new buffer's capacity, in floats.

• createExternalTexture

  public static int createExternalTexture()

  Creates a GL_TEXTURE_EXTERNAL_OES with default configuration of GL_LINEAR filtering and GL_CLAMP_TO_EDGE wrapping.
