// Function to adjust the volume of a video element
function adjustVideoVolume(videoElement, volume) {
  // Create an audio context
  const audioCtx = new (window.AudioContext || window.webkitAudioContext)();
  
  // Create a media element source from the video element
  const source = audioCtx.createMediaElementSource(videoElement);
  
  // Create a gain node to control the volume
  const gainNode = audioCtx.createGain();
  
  // Set the desired volume level
  gainNode.gain.value = volume;
  
  // Connect the video's audio to the gain node
  source.connect(gainNode);
  
  // Connect the gain node to the audio context's destination (output)
  gainNode.connect(audioCtx.destination);
}

// Usage example:
var videoElement = document.querySelector("video");
// Adjust this value to set the desired volume level (2 for double volume)
