  • Enum Constant Details

    • UNKNOWN

      public static final VideoCaptionType UNKNOWN
      Unknown type of CC

    • CEA608_RAW

      public static final VideoCaptionType CEA608_RAW
      CEA-608 as byte pairs. Note that this format is not recommended since is does not specify to which field the caption comes from and therefore assumes it comes from the first field (and that there is no information on the second field). Use GSTVIDEOCAPTIONTYPECEA708RAW if you wish to store CEA-608 from two fields and prefix each byte pair with 0xFC for the first field and 0xFD for the second field.

    • CEA608_S334_1A

      public static final VideoCaptionType CEA608_S334_1A
      CEA-608 as byte triplets as defined in SMPTE S334-1 Annex A. The second and third byte of the byte triplet is the raw CEA608 data, the first byte is a bitfield: The top/7th bit is 0 for the second field, 1 for the first field, bit 6 and 5 are 0 and bits 4 to 0 are a 5 bit unsigned integer that represents the line offset relative to the base-line of the original image format (line 9 for 525-line field 1, line 272 for 525-line field 2, line 5 for 625-line field 1 and line 318 for 625-line field 2).

    • CEA708_RAW

      public static final VideoCaptionType CEA708_RAW
      CEA-708 as cc_data byte triplets. They can also contain 608-in-708 and the first byte of each triplet has to be inspected for detecting the type.

    • CEA708_CDP

      public static final VideoCaptionType CEA708_CDP
      CEA-708 (and optionally CEA-608) in a CDP (Caption Distribution Packet) defined by SMPTE S-334-2. Contains the whole CDP (starting with 0x9669).

  • Method Details

    • values

      public static VideoCaptionType[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static VideoCaptionType valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
      NullPointerException - if the argument is null

    • of

      public static VideoCaptionType of(int value)
      Create a new VideoCaptionType for the provided value
      Parameters:
      value - the enum value
      Returns:
      the enum for the provided value

    • getValue

      public int getValue()
      Get the numeric value of this enum
      Specified by:
      getValue in interface Enumeration
      Returns:
      the enum value

    • of

      public static VideoCaptionType of(MemorySegment address)
      Create a new VideoCaptionType for the value in the provided memory address.
      Parameters:
      address - the memory address holding a enum value
      Returns:
      the enum for the value in the provided memory address

    • getType

      public static @Nullable Type getType()
      Get the GType of the VideoCaptionType class.
      Returns:
      the GType

    • fromCaps

      public static VideoCaptionType fromCaps(Caps caps)
      Parses fixed Closed Caption GstCaps and returns the corresponding caption type, or UNKNOWN.
      Parameters:
      caps - Fixed GstCaps to parse
      Returns:
      GstVideoCaptionType.

    • toCaps

      public Caps toCaps()
      Creates new caps corresponding to type.
      Returns:
      new GstCaps
