Adjust bandwidth

Launcher.connection().changeBandwidth(
  8000, // start bitrate kbps
  10000, // max bitrate kbps
  5000, // min bitrate kbps
)
Launcher.connection().changeBandwidth(

)

Statistics

window.setInterval(() => {
  const { fps, bitrate, packetLossRate, latency, averageJitterBufferDelay } = launcher.report()
  console.log(`
    FPS: ${fps}
    biterate: ${bitrate}kbps
    latency: ${latency}ms

ToggleFullscreen

/* NOTE: fullscreen need user activation gesture

launcher.openCamera()
// stop
launcher.closeCamera()

File Transfer

//Upload file to node

//Note: When dir is empty, it actually points to the "<User>/Downloads" directory in node
launcher.changeUploadDir(dir:string)
launcher.uploadFile(file: File, onStateChange?: FileUploadStateChangeHandler)

//Download file from node
launcher.downloadFileByFullPath(absolutePath:string)

Destroy
