name	panopto-mp4-bulk-download
description	Extract real downloadable mp4 URLs from Panopto and similar HLS lecture players, then batch-download all lectures with manifests and retry logic. Use when users ask to download many class videos from a logged-in Panopto folder, to automate IDM-style URL discovery, or to derive fragmented.mp4 links from Viewer pages.

Panopto MP4 Bulk Download

Use This Workflow

1. Ensure the user is already logged into Panopto in agent-browser.
2. Use a headed persistent session (~/.agent-browser-session).
3. Pass the folder list URL to the bundled script.

Run The Bundled Script

scripts/panopto_bulk_mp4.sh "<panopto-folder-list-url>" "<output-dir>" "<manifest-dir>"

Example:

scripts/panopto_bulk_mp4.sh \
  "https://scs.hosted.panopto.com/Panopto/Pages/Sessions/List.aspx?...#folderID=%22...%22" \
  "downloads/panopto_mp4" \
  "downloads/panopto_manifests"

What The Script Does

1. Open the folder list page in agent-browser.
2. Extract all lecture Viewer.aspx?id=... links.
3. Open each lecture page and click Play.
4. Read browser performance entries to capture media URLs.
5. Prefer /fragmented.mp4; if absent, derive it from /index.m3u8.
6. Download all videos with curl -L retries.
7. Write manifests and failure reports.

Required Behavior During Manual Automation

1. For every agent-browser open, always use --headed --session <name>.
2. If open fails, immediately run:

agent-browser --session <name> close
agent-browser --headed --session <name> open <url>

Outputs

• lecture_mp4_manifest.tsv: lecture metadata and extracted mp4 URLs
• extract_failed.txt: lecture pages where URL extraction failed
• download_failed.txt: downloads that failed after retries
