IPlayer

public static enum IPlayer.AlphaRenderMode
extends java.lang.Enum<IPlayer.AlphaRenderMode>

Alpha rendering modes.

Used for rendering video frames that contain an alpha channel (transparency). The video frame is split into an RGB image region and an alpha channel region. The player extracts both parts based on the specified layout and performs alpha blending. Commonly used for live-stream gifts, animated overlays, and other transparent effects.

Enum Constant Detail

RENDER_MODE_ALPHA_NONE

public static final IPlayer.AlphaRenderMode RENDER_MODE_ALPHA_NONE

No alpha rendering. The video frame is a standard RGB image without transparency.

RENDER_MODE_ALPHA_AT_RIGHT

public static final IPlayer.AlphaRenderMode RENDER_MODE_ALPHA_AT_RIGHT

Alpha channel is on the right side of the frame. The left half contains the RGB image, and the right half contains the alpha channel (grayscale). The player uses the right-side alpha values to blend the left-side image with transparency.

RENDER_MODE_ALPHA_AT_LEFT

public static final IPlayer.AlphaRenderMode RENDER_MODE_ALPHA_AT_LEFT

Alpha channel is on the left side of the frame. The right half contains the RGB image, and the left half contains the alpha channel (grayscale). The player uses the left-side alpha values to blend the right-side image with transparency.

RENDER_MODE_ALPHA_AT_TOP

public static final IPlayer.AlphaRenderMode RENDER_MODE_ALPHA_AT_TOP

Alpha channel is on the top of the frame. The bottom half contains the RGB image, and the top half contains the alpha channel (grayscale). The player uses the top-side alpha values to blend the bottom-side image with transparency.

RENDER_MODE_ALPHA_AT_BOTTOM

public static final IPlayer.AlphaRenderMode RENDER_MODE_ALPHA_AT_BOTTOM

Alpha channel is on the bottom of the frame. The top half contains the RGB image, and the bottom half contains the alpha channel (grayscale). The player uses the bottom-side alpha values to blend the top-side image with transparency.

Method Detail

values

public static IPlayer.AlphaRenderMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (IPlayer.AlphaRenderMode c : IPlayer.AlphaRenderMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static IPlayer.AlphaRenderMode valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getValue

public int getValue()

Query the value of the specified parameter.

Returns:

The returned value.
