Method Detail

values

public static CodecFlag[] 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 (CodecFlag c : CodecFlag.values())
    System.out.println(c);

Returns:

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

valueOf

public static CodecFlag valueOf(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:

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

NullPointerException - if the argument is null

value

public final int value()

Get the codec flag id defined in FFmpeg.

Returns:

FFmpeg codec flag id.

byId

public static CodecFlag byId(int id)

Get a CodecFlag that matches to the specified FFmpeg id.

Parameters:

id - FFmpeg codec flag id.

Returns:

matching codec flag, or null if id is not defined.
