TimestampAdjustmentShaderProgram

public TimestampAdjustmentShaderProgram(
    TimestampAdjustment.TimestampMap timestampMap
)

public void flush()

Flushes the GlShaderProgram.

The GlShaderProgram should reclaim the ownership of its allocated textures, notify its InputListener about the flush event, and report its availability if necessary.

The implementation must not output frames until after this method returns.

public void queueInputFrame(
    GlObjectsProvider glObjectsProvider,
    GlTextureInfo inputTexture,
    long presentationTimeUs
)

Processes an input frame if possible.

The GlShaderProgram owns the accepted frame until it calls onInputFrameProcessed. The caller should not overwrite or release the texture before the GlShaderProgram has finished processing it.

This method must only be called when the GlShaderProgram can accept an input frame.

public void release()

Releases all resources.

public void releaseOutputFrame(GlTextureInfo outputTexture)

Notifies the GlShaderProgram that the frame on the given output texture is no longer used and can be overwritten.

public void setErrorListener(
    Executor executor,
    GlShaderProgram.ErrorListener errorListener
)

Sets the ErrorListener.

The ErrorListener is invoked on the provided Executor.

public void setInputListener(GlShaderProgram.InputListener inputListener)

Sets the InputListener.

The InputListener should be invoked on the thread that owns the parent OpenGL context. For example, DefaultVideoFrameProcessor invokes the InputListener methods on its internal thread.

public void setOutputListener(GlShaderProgram.OutputListener outputListener)

Sets the OutputListener.

The OutputListener should be invoked on the thread that owns the parent OpenGL context. For example, DefaultVideoFrameProcessor invokes the OutputListener methods on its internal thread.

public void signalEndOfCurrentInputStream()

Notifies the GlShaderProgram that no further input frames belonging to the current input stream will be queued.

Input frames that are queued after this method is called belong to a different input stream.
