Summary

Nested types
`class PreviewingSingleInputVideoGraph.Factory : PreviewingVideoGraph.Factory` A factory for creating a `PreviewingSingleInputVideoGraph`.

Public functions
`Unit`	`renderOutputFrame(renderTimeNs: Long)` Renders the oldest unrendered output frame that has become `available for rendering` at the given `renderTimeNs`.

`VideoFrameProcessor!`	`getProcessor(inputIndex: Int)` Returns the `VideoFrameProcessor` that handles the processing for an input registered via `registerInput`.
`Boolean`	`hasProducedFrameWithTimestampZero()` Returns whether the `VideoGraph` has produced a frame with zero presentation timestamp.
`Unit`	`initialize()` Initialize the VideoGraph}.
`Unit`	`registerInput(inputIndex: Int)` Registers a new input to the `VideoGraph`.
`Unit`	`release()` Releases the associated resources.
`Unit`	`setOutputSurfaceInfo(outputSurfaceInfo: SurfaceInfo?)` Sets the output surface and supporting information.

abstract Unit

registerInput(inputIndex: @IntRange(from = 0) Int)

Registers a new input to the VideoGraph.

`Long`	`initialTimestampOffsetUs`
`Int`	`inputIndex`

fun renderOutputFrame(renderTimeNs: Long): Unit

Renders the oldest unrendered output frame that has become available for rendering at the given renderTimeNs.

This will either render the output frame to the output surface, or drop the frame, per renderTimeNs.

The renderTimeNs may be passed to eglPresentationTimeANDROID depending on the implementation.

Parameters
`renderTimeNs: Long`	The render time to use for the frame, in nanoseconds. The render time can be before or after the current system time. Use `DROP_OUTPUT_FRAME` to drop the frame, or `RENDER_OUTPUT_FRAME_IMMEDIATELY` to render the frame immediately.
