public enum AVTimestamp

Undocumented

  • Internal timebase represented as integer

    Declaration

    Swift

    public static let timebase: Int32

  • Internal timebase represented as fractional value

    Declaration

    Swift

    public static let timebaseQ: AVRational

  • Undefined timestamp value.

    Usually reported by demuxer that work on containers that do not provide either pts or dts.

    Declaration

    Swift

    public static let noPTS: Int64

  • Compare two timestamps each in its own timebase.

    Warning

    The result of the function is undefined if one of the timestamps is outside the int64_t range when represented in the other’s timebase.

    Declaration

    Swift

    public static func compareTimestamp(
    _ ts_a: Int64, _ tb_a: AVRational,
    _ ts_b: Int64, _ tb_b: AVRational
) -> Int

    Return Value

    One of the following values:

    • -1 if ts_a is before ts_b
    • 1 if ts_a is after ts_b
    • 0 if they represent the same position
