    Controls how a frame is presented with options to set the output resolution and choose how to map the input pixels onto the output frame geometry (for example, by stretching the input frame to match the specified output frame, or fitting the input frame using letterboxing).

    The background color of the output frame will be black, with alpha = 0 if applicable.

      • LAYOUT_SCALE_TO_FIT

        public static final int LAYOUT_SCALE_TO_FIT
        Deprecated.
        Empty pixels added above and below the input frame (for letterboxing), or to the left and right of the input frame (for pillarboxing), until the desired aspect ratio is achieved. All input frame pixels will be within the output frame.

        When applying:

        • letterboxing, the output width will default to the input width, and the output height will be scaled appropriately.
        • pillarboxing, the output height will default to the input height, and the output width will be scaled appropriately.

      • LAYOUT_SCALE_TO_FIT_WITH_CROP

        public static final int LAYOUT_SCALE_TO_FIT_WITH_CROP
        Deprecated.
        Pixels cropped from the input frame, until the desired aspect ratio is achieved. Pixels may be cropped either from the bottom and top, or from the left and right sides, of the input frame.

        When cropping from the:

        • bottom and top, the output width will default to the input width, and the output height will be scaled appropriately.
        • left and right, the output height will default to the input height, and the output width will be scaled appropriately.

        Constant Field Values

      • LAYOUT_STRETCH_TO_FIT

        public static final int LAYOUT_STRETCH_TO_FIT
        Deprecated.
        Frame stretched larger on the x or y axes to fit the desired aspect ratio.

        When stretching to a:

        • taller aspect ratio, the output width will default to the input width, and the output height will be scaled appropriately.
        • narrower aspect ratio, the output height will default to the input height, and the output width will be scaled appropriately.

      • createForAspectRatio

        public static Presentation createForAspectRatio​(@FloatRange(from=0.0,fromInclusive=false)
                                                float aspectRatio,
                                                @com.google.android.exoplayer2.effect.Presentation.Layout int layout)
        Deprecated.
        Creates a new Presentation instance.

        The output frame will have the given aspect ratio (width/height ratio). Width or height will be resized to conform to this aspectRatio, given a Presentation.Layout.

        Parameters:
        aspectRatio - The aspect ratio (width/height ratio) of the output frame. Must be positive.
        layout - The layout of the output frame.

      • createForHeight

        public static Presentation createForHeight​(int height)
        Deprecated.
        Creates a new Presentation instance.

        The output frame will have the given height. Width will scale to preserve the input aspect ratio. For example, a 1920x1440 video can be scaled to 640x480 by passing a height of 480.

        Parameters:
        height - The height of the output frame, in pixels.

      • createForWidthAndHeight

        public static Presentation createForWidthAndHeight​(int width,
                                                   int height,
                                                   @com.google.android.exoplayer2.effect.Presentation.Layout int layout)
        Deprecated.
        Creates a new Presentation instance.

        The output frame will have the given width and height, given a Presentation.Layout.

        Width and height must be positive integers representing the output frame's width and height.

        Parameters:
        width - The width of the output frame, in pixels.
        height - The height of the output frame, in pixels.
        layout - The layout of the output frame.

      • isNoOp

        public boolean isNoOp​(int inputWidth,
                      int inputHeight)
        Deprecated.
        Description copied from interface: GlEffect
        Returns whether a GlEffect applies no change at every timestamp.

        This can be used as a hint to skip this instance.

        Specified by:
        isNoOp in interface GlEffect
        Parameters:
        inputWidth - The input frame width, in pixels.
        inputHeight - The input frame height, in pixels.
