SharePoint Video Downloader detects video manifests and stream URLs on SharePoint/OneDrive pages and generates download commands with the correct authentication flags. It supports both --cookies-from-browser (browser must be closed) and --cookies cookies.txt (browser can stay open) workflows.

Built using Chrome Manifest V3.

Features

Detects SharePoint stream URLs — /transform/videomanifest (DASH/HLS), mediap.svc.ms proxy manifests, oneDrive.transcode segment endpoints, and direct download.aspx links.
Per-tab URL capture — stores up to 20 URLs per tab, deduplicated.
Current Page shortcut — one-click copy of a yt-dlp command using the active SharePoint tab URL (uses the built-in SharePoint extractor).
Two cookie modes — --cookies-from-browser <browser> and --cookies cookies.txt.
Cookie lock warning — shows a warning when Edge/Chrome/Brave is selected, since Chromium locks the cookie database while the browser is open.
Customizable output — quality (Best, 1080p, 720p, 480p), format (MP4, MKV, TS), and custom filename.
Copy buttons for all commands.

Installation

Prerequisites

Edge or Chrome (Manifest V3, version 88+).
yt-dlp — pip install yt-dlp or download from github.com/yt-dlp/yt-dlp.
FFmpeg (optional) — ffmpeg.org.

Steps

Clone or download the repository

git clone https://github.com/MiniduTH/Sharepoint-Downloader.git

Load the extension
- Edge: edge://extensions/ → Enable Developer mode → Load unpacked → select the folder.
- Chrome: chrome://extensions/ → same steps.

Usage

Recommended: Current Page method

Open the SharePoint video page in your browser.
Click the extension icon.
In the Current Page card, click Copy yt-dlp (cookies.txt) (if Edge is open) or Copy yt-dlp Command (if you'll close the browser first).
Paste into a terminal and run.

Option A: `--cookies-from-browser` (no extra setup, but browser must be closed)

Chromium-based browsers (Edge, Chrome, Brave) lock the cookie database while running. You must close the browser before running the command.

# 1. Close Edge/Chrome completely
# 2. Run:
yt-dlp --cookies-from-browser edge -f "bestvideo+bestaudio/best" --merge-output-format mp4 -o "vid.mp4" "https://sitename.com/..."
# 3. Reopen the browser

Firefox does not lock its cookie database, so --cookies-from-browser firefox works while the browser is open.

Option B: `--cookies cookies.txt` ✅ Confirmed working

Export cookies while the browser is open using the Get cookies.txt LOCALLY extension, then run:

yt-dlp --cookies cookies.txt -f "bestvideo+bestaudio/best" --merge-output-format mp4 -o "vid.mp4" "https://sitename.com/..."

Steps to export cookies.txt:

Install Get cookies.txt LOCALLY in Edge/Chrome.
Navigate to sitename.com (or your SharePoint domain).
Click the extension icon → Export → save as cookies.txt in the same folder where you'll run yt-dlp.
Use the Copy yt-dlp (cookies.txt) button in this extension to get the command.

Captured Stream URLs

The extension also intercepts manifest URLs as you play the video:

Play the video on SharePoint.
Open the extension popup — captured URLs appear in the Captured Stream URLs list.
Click a URL to generate FFmpeg and yt-dlp commands for it in the Download Commands card.
