Download any video from Microsoft Teams, SharePoint and OneDrive

Videos like

- https://{ORGID}.sharepoint.com/personal/{USERID}/_layouts/15/stream.aspx?id={VIDEOID}%2Emp4&ga=1
- https://{ORGID}.sharepoint.com/:v:/p/{USERID}/{VIDEOID}

1. Run video from SharePoint corporate account or OneDrive,
2. In Chrome open Web inspector and in Network filter by videomanifest
3. Copy this url
4. Run ffmpeg -i "%URL%" -codec copy outputvideo.mp4

For the manual peeps, I tried this with a Teams recording (https://xxx-my.sharepoint.com/...) :

1. Do the steps until trimming the URL up to &format=dash
2. For that videomanifest URL in the Network tab, check its Request Headers. Copy the X-SPOPacToken

4. Append &access_token=<copied_token> into your URL
5. Do the rest of the steps

Note: my video was under 100MB and download was fast, so I encountered no problems.
But while I was debugging around and reloading the page, I noticed this token would change, so it might have an expiry, which might interfere with long downloads.
