Either using rest API, Google Scripts, Node SDK, whatever works.

I'm seeing this in the docs but that doesn't seem to tell me the duration:

function watchFile(fileId, channelId, channelType, channelAddress) {
  var resource = {
    'id': channelId,
    'type': channelType,
    'address': channelAddress
  };
  var request = gapi.client.drive.files.watch({
    'fileId': fileId,
    'resource': resource
  });
  request.execute(function(channel){console.log(channel);});
}

I found this link but it doesn't seem to help https://apis-nodejs.firebaseapp.com/drive/classes/Resource$Files.html#watch

  • You want to retrieve the duration of the video on your Google Drive.
  • You want to achieve this using Google Apps Script.

If my understanding is correct, how about this sample script? In this modification, I used files.get and files.list methods of Drive API. From your question, I thought that the script that the endpoint is directly requests might be useful for your situation. So I proposed the following script.

1. Using files.get method

In this sample script, the duration is retrieved from a video file.

Sample script:

function sample1() {
  var fileId = "###"; // Please set the file ID of the video file.

  var fields = "mimeType,name,videoMediaMetadata"; // duration is included in "videoMediaMetadata"
  var url = "https://www.googleapis.com/drive/v3/files/" + fileId + "?fields=" + encodeURIComponent(fields) + "&access_token=" + ScriptApp.getOAuthToken();
  var res = UrlFetchApp.fetch(url);
  var obj = JSON.parse(res);
  Logger.log("filename: %s, duration: %s seconds", obj.name, obj.videoMediaMetadata.durationMillis / 1000);

  // DriveApp.getFiles() // This line is put for automatically detecting the scope (https://www.googleapis.com/auth/drive.readonly) for this script.
}

2. Using files.list method

In this sample script, the durations are retrieved from a folder including the video files.

Sample script:

function sample2() {
  var folderId = "###"; // Please set the folder ID including the video files.

  var q = "'" + folderId + "' in parents and trashed=false";
  var fields = "files(mimeType,name,videoMediaMetadata)"; // duration is included in "videoMediaMetadata"
  var url = "https://www.googleapis.com/drive/v3/files?q=" + encodeURIComponent(q) + "&fields=" + encodeURIComponent(fields) + "&access_token=" + ScriptApp.getOAuthToken();
  var res = UrlFetchApp.fetch(url);
  var obj = JSON.parse(res);
  for (var i = 0; i < obj.files.length; i++) {
    Logger.log("filename: %s, duration: %s seconds", obj.files[i].name, obj.files[i].videoMediaMetadata.durationMillis / 1000);
  }

  // DriveApp.getFiles() // This line is put for automatically detecting the scope (https://www.googleapis.com/auth/drive.readonly) for this script.
}

Note:

  • These are simple sample scripts. So please modify them for your situation.
  • I'm not sure about the format of your video files. So if above script cannot be used for your situation, I apologize.

If I misunderstood your question and this was not the result you want, I apologize.
