public DrawableOverlay()

public static DrawableOverlay createStaticDrawableOverlay(
    Drawable drawable,
    OverlaySettings overlaySettings
)

Creates a DrawableOverlay that shows the Drawable with the same throughout the whole video.

Parameters
`Drawable drawable`	The `Drawable` to be displayed.
`OverlaySettings overlaySettings`	The `OverlaySettings` configuring how the overlay is displayed on the frames.

public Bitmap getBitmap(long presentationTimeUs)

Returns the overlay bitmap displayed at the specified timestamp.

Parameters
`long presentationTimeUs`	The presentation timestamp of the current frame, in microseconds.

Throws
`androidx.media3.common.VideoFrameProcessingException`	If an error occurs while processing or drawing the frame.

public abstract Drawable getDrawable(long presentationTimeUs)

Returns the overlay Drawable displayed at the specified timestamp.

The drawable must have its bounds set via setBounds for drawable to be displayed on the frame.

Parameters
`long presentationTimeUs`	The presentation timestamp of the current frame, in microseconds.
