Summary

Nested types
`public final class PreviewingSingleInputVideoGraph.Factory implements PreviewingVideoGraph.Factory` A factory for creating a `PreviewingSingleInputVideoGraph`.

Public methods
`void`	`renderOutputFrame(long renderTimeNs)` Renders the oldest unrendered output frame that has become `available for rendering` at the given `renderTimeNs`.

`final long`	`initialTimestampOffsetUs`
`int`	`inputIndex`
`final @Nullable Presentation`	`presentation`

`long`	`getInitialTimestampOffsetUs()`
`int`	`getInputIndex()`
`@Nullable Presentation`	`getPresentation()`
`VideoFrameProcessor`	`getProcessor(int inputIndex)` 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.
`void`	`initialize()` Initialize the VideoGraph}.
`void`	`registerInput(int inputIndex)` Registers a new input to the `VideoGraph`.
`void`	`release()` Releases the associated resources.
`void`	`setOutputSurfaceInfo(@Nullable SurfaceInfo outputSurfaceInfo)` Sets the output surface and supporting information.

abstract void

registerInput(@IntRange(from = 0) int inputIndex)

Registers a new input to the VideoGraph.

public void renderOutputFrame(long renderTimeNs)

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
`long renderTimeNs`	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.
