Flag

public struct Flag : OptionSet

Encoding support

These flags can be passed in AVCodecContext.flags before initialization.

  • Allow decoders to produce frames with data planes that are not aligned to CPU requirements (e.g. due to cropping).

    Declaration

    Swift

    public static let unaligned: AVCodecContext.Flag

  • Use fixed qscale.

    Declaration

    Swift

    public static let qscale: AVCodecContext.Flag

  • 4 MV per MB allowed / advanced prediction for H.263.

    Declaration

    Swift

    public static let p4mv: AVCodecContext.Flag

  • Output even those frames that might be corrupted.

    Declaration

    Swift

    public static let outputCorrupted: AVCodecContext.Flag

  • Use qpel MC.

    Declaration

    Swift

    public static let qpel: AVCodecContext.Flag

  • Use internal 2pass ratecontrol in first pass mode.

    Declaration

    Swift

    public static let pass1: AVCodecContext.Flag

  • Use internal 2pass ratecontrol in second pass mode.

    Declaration

    Swift

    public static let pass2: AVCodecContext.Flag

  • loop filter.

    Declaration

    Swift

    public static let loopFilter: AVCodecContext.Flag

  • error[?] variables will be set during encoding.

    Declaration

    Swift

    public static let psnr: AVCodecContext.Flag

  • Input bitstream might be truncated at a random location instead of only at frame boundaries.

    Declaration

    Swift

    public static let truncated: AVCodecContext.Flag

  • Use interlaced DCT.

    Declaration
