Inheritance

ScrcpyOptionsX_YY classes use a special inheritance mechanism to allow breaking changes between versions. When features change in the server, a new options class is created, and only the changed behaviors are overridden.

There are several virtual methods in the base class that can be overridden in the derived class.

declare class ScrcpyOptions {
  abstract serialize(): string[];
  /**
   * Set the essential options to let Scrcpy server print out available encoders.
   */
  setListEncoders(): void;
  /**
   * Set the essential options to let Scrcpy server print out available displays.
   */
  setListDisplays(): void;
  /**
   * Parse encoder information from Scrcpy server output
   * @param line One line of Scrcpy server output
   */
  parseEncoder(line: string): ScrcpyEncoder | undefined;
  /**
   * Parse display information from Scrcpy server output
   * @param line One line of Scrcpy server output
   */
  parseDisplay(line: string): ScrcpyDisplay | undefined;
  /**
   * Parse the device metadata from video stream according to the current version and options.
   * @param stream The video stream.
   * @returns
   * A tuple of the video stream and the metadata.
   *
   * The returned video stream may be different from the input stream, and should be used for further processing.
   */
  parseVideoStreamMetadata(
    stream: ReadableStream<Uint8Array>
  ): ValueOrPromise<ScrcpyVideoStream>;
  parseAudioStreamMetadata(
    stream: ReadableStream<Uint8Array>
  ): ValueOrPromise<ScrcpyAudioStreamMetadata>;
  parseDeviceMessage(id: number, stream: AsyncExactReadable): Promise<void>;
  createMediaStreamTransformer(): TransformStream<
    Uint8Array,
    ScrcpyMediaStreamPacket
  >;
  serializeInjectTouchControlMessage(
    message: ScrcpyInjectTouchControlMessage
  ): Uint8Array;
  serializeBackOrScreenOnControlMessage(
    message: ScrcpyBackOrScreenOnControlMessage
  ): Uint8Array | undefined;
  /**

   * @param message The clipboard control message
   * @returns A `Uint8Array` containing the binary data, or a tuple of the binary data and a promise that resolves when the clipboard is updated on the device
   */
