Type definitions

type FfmpegVp8EncoderOptions = {
  type: "ffmpeg_vp8";
  bitrate?:
    | number
    | {
      average_bitrate: number;
      max_bitrate: number;
    };
  keyframe_interval_ms?: number;
  ffmpeg_options?: Record<string, string>;
};

Properties

bitrate

Desired bitrate of the output stream, in bits per second. If only a number is specified then it defines the average_bitrate. The max_bitrate is then set to 1.25x this value.

• Type: number | { average_bitrate: number; max_bitrate: number; }
• Default value: Calculated based on framerate and resolution. Eg. for 30 FPS in 1080p the average_bitrate would be 5000 kb/s and max_bitrate 6250 kb/s.

Properties

average_bitrate

Average bitrate measured in bits per second. Encoder will try to keep the bitrate around the provided average, but may temporarily increase it to the provided max bitrate.

• Type: number

max_bitrate

• Type: number

keyframe_interval_ms

Maximal interval between 2 consecutive keyframes, in milliseconds.

• Type: number
• Default value: 5000
