Reference

Type definitions

type FfmpegVp8EncoderOptions = {
  type: "ffmpeg_vp8";
  bitrate?:
    | number
    | {
      averageBitrate: number;
      maxBitrate: number;
    };
  keyframeIntervalMs?: number;
  ffmpegOptions?: 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 averageBitrate. The maxBitrate is then set to 1.25x this value.

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

Properties

averageBitrate

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

maxBitrate

Max bitrate measured in bits per second.

• Type: number

---

keyframeIntervalMs

Maximal interval between 2 consecutive keyframes, in milliseconds.

• Type: number
• Default value: 5000
