Deprecated. com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

Specifies a 4x4 transformation Matrix to apply in the vertex shader for each input frame.

The matrix is applied to points given in normalized device coordinates (-1 to 1 on x, y, and z axes). Transformed pixels that are moved outside of the normal device coordinate range are clipped.

Output frame pixels outside of the transformed input frame will be black, with alpha = 0 if applicable.

Description copied from interface: GlEffect

Returns a GlShaderProgram that applies the effect. Specified by:toGlShaderProgram in interface GlEffectParameters:context - A Context.useHdr - Whether input textures come from an HDR source. If true, colors will be in linear RGB BT.2020. If false, colors will be in linear RGB BT.709.Throws:VideoFrameProcessingException - If an error occurs while creating the GlShaderProgram.
