sendDummyByte

info

Added in Scrcpy 1.22

  • Type: boolean
  • Default value: true

Controls whether the server should send a 0 byte at the start of the video stream to detect connection issues.

By default, sending a dummy byte is enabled in Scrcpy when using forward tunnel mode (controlled by the tunnelForward option), meaning the server sends a 0 byte at the start of the video stream to detect connection issues.

This mechanism is crucial for confirming that the connection between the client and the server is established in forward tunnel mode.

Adding this option with a value of true has no effect since this is the default behavior in forward tunnel mode.

Only setting this option to false will disable sending the dummy byte at the start of the video stream.

  • tunnelForward: Use ADB forward tunnel instead of reverse tunnel

Example​

import { ScrcpyOptions1_22 } from "@yume-chan/scrcpy";

const options = new ScrcpyOptions1_22({
    sendDummyByte: false, // Disable sending dummy byte
});
