A simple tool that traverses a Google Drive, finds all files of mimeType containing 'video', and outputs .strm files that direct the Kodi GDrive Addon (https://forum.kodi.tv/showthread.php?tid=177557) to play them.

The script works from the Google drive Changes API method, so it remembers the last files it has processed, and subsequent executions only track changes from that point forward.

To use the Python script directly

• Python 3.5+
• package google-api-python-client
  run pip install --upgrade google-api-python-client to install

Download getstreams.py, place it in an empty local folder, and run it from command line.

By default, on first execution, getstreams starts from the inception of your Google Drive, finds all video files, prints their full path, then outputs a hierarchy of .strm files, each containing a link of the format plugin://plugin.video.gdrive/?mode=video&filename=abc&title=xyz.

The first time you run getstreams, you will be prompted with a Google authorization page asking you for permission to view and manage your Google Drive files. Once authorized, a credential file will be saved in .credentials\get-google-drive-streams.json under your home directory. You don't need to manually authorize getstreams again until you delete this credential file or revoke permission on your Google account page.
You can specify a custom location for the credential file by using the command line option --credfile. This is helpful if you're using multiple Google accounts with getstreams.

getstreams finds video files by scanning through your Google Drive activity history. On first run, it must start from the very beginning to ensure no files are missed, so it might take some time. After first run, getstreams saves a file named page_token in its own parent folder. This file contains a single number indicating an appropriate starting position in your Google Drive activity history for future scans, so they can be much faster than the first one. Each run of getstreams updates page_token as appropriate.
You can specify a custom location or name for the page_token file by using the command line option --ptokenfile.

More command line options are available. You can read about them by running getstreams --help.

usage: getstreams.py [-h] [-v] [-q] [-t SECS] [-m] [--noprogress] [--nopath]
                     [--logfile PATH] [--ptokenfile PATH] [--streampath PATH]
                     [--credfile PATH]

optional arguments:
  -h, --help            show this help message and exit
  -v, --view            Only view which files are to be parsed without
                        creating files
  -q, --quiet           Quiet mode. Only show file count.
  -t SECS, --timeout SECS
                        Specify timeout period in seconds. Default is 300
  --noprogress          Don't show scanning progress. Useful when directing
                        output to files.
  --nopath              Do not parse full path for files, but store them flat.
                        Faster, but messy.
  --logfile PATH        Path to log file. Default is no logs
  --ptokenfile PATH     Path to page token file. Default is "page_token" in
                        getstreams.py's parent folder
  --streampath PATH     Path to stream output directory. Default is
                        strm/ in getstreams.py's parent folder.
  --credfile PATH       Path to OAuth2Credentials file. Default is
                        ~/.credentials/get-google-drive-streams.json

All the heavy lifting here was stolen shamelessly from Chenfeng Bao's Google Drive Trash Cleaner. The original idea for that script's working mechanism is borrowed from this Stack Overflow question. This is all just a tiny remora stuck to the side of the GDrive Kodi Addon.
