SingleFrameGlShaderProgram

Kotlin |Java

@UnstableApi
abstract class SingleFrameGlShaderProgram : BaseGlShaderProgram

kotlin.Any
↳	androidx.media3.effect.BaseGlShaderProgram
	↳	androidx.media3.effect.SingleFrameGlShaderProgram

Manages a GLSL shader program for processing a frame. Implementations generally copy input pixels into an output frame, with changes to pixels specific to the implementation.

SingleFrameGlShaderProgram implementations must produce exactly one output frame per input frame with the same presentation timestamp. For more flexibility, implement directly.

All methods in this class must be called on the thread that owns the OpenGL context.

Summary

Public constructors
`SingleFrameGlShaderProgram(useHighPrecisionColorComponents: Boolean)` Creates a `SingleFrameGlShaderProgram` instance.

Inherited functions

From androidx.media3.effect.BaseGlShaderProgram

`abstract Size!`	`configure(inputWidth: Int, inputHeight: Int)` Configures the instance based on the input dimensions.
`abstract Unit`	`drawFrame(inputTexId: Int, presentationTimeUs: Long)` Draws one frame.
`Unit`	`@CallSuper flush()` Flushes the `GlShaderProgram`.
`Unit`	`onError(e: Exception!)`
`Unit`	`queueInputFrame( glObjectsProvider: GlObjectsProvider!, inputTexture: GlTextureInfo!, presentationTimeUs: Long )` Processes an input frame if possible.
`Unit`	`@CallSuper release()` Releases all resources.
`Unit`	`releaseOutputFrame(outputTexture: GlTextureInfo!)` Notifies the `GlShaderProgram` that the frame on the given output texture is no longer used and can be overwritten.
`Unit`	`setErrorListener( errorListenerExecutor: Executor!, errorListener: GlShaderProgram.ErrorListener! )` Sets the `ErrorListener`.
`Boolean`	`shouldClearTextureBuffer()` Returns `true` if the texture buffer should be cleared before calling `drawFrame` or `false` if it should retain the content of the last drawn frame.
`Unit`	`signalEndOfCurrentInputStream()` Notifies the `GlShaderProgram` that no further input frames belonging to the current input stream will be queued.

SingleFrameGlShaderProgram

SingleFrameGlShaderProgram(useHighPrecisionColorComponents: Boolean)

Creates a SingleFrameGlShaderProgram instance.

Parameters
`useHighPrecisionColorComponents: Boolean`	If `false`, uses colors with 8-bit unsigned bytes. If `true`, use 16-bit (half-precision) floating-point.
