Mp4Settings

public struct Mp4Settings : AWSShape

Undocumented

  • Declaration

    Swift

    public static var _members: [AWSShapeMember]

  • When enabled, file composition times will start at zero, composition times in the ‘ctts’ (composition time to sample) box for B-frames will be negative, and a ‘cslg’ (composition shift least greatest) box will be included per 14496-1 amendment 1. This improves compatibility with Apple players and tools.

    Declaration

    Swift

    public let cslgAtom: Mp4CslgAtom?

  • Ignore this setting unless compliance to the CTTS box version specification matters in your workflow. Specify a value of 1 to set your CTTS box version to 1 and make your output compliant with the specification. When you specify a value of 1, you must also set CSLG atom (cslgAtom) to the value INCLUDE. Keep the default value 0 to set your CTTS box version to 0. This can provide backward compatibility for some players and packagers.

    Swift

    public let cttsVersion: Int?

  • Inserts a free-space box immediately after the moov box.

    Declaration

    Swift
