oscars-pool/python_video_server

Python video server (Range streaming + JWT + Mongo)

This is a small standalone server that mirrors the app’s /api/video/:id behavior:

• Looks up movies._id == :id in MongoDB and reads the video_file field
• Streams the file from VIDEO_FILES_DIR with HTTP Range support (seeking works)
• Auth via the same JWT (Authorization: Bearer ...), plus a video_auth cookie for <video>

Run

python -m pip install -r python_video_server/requirements.txt
export MONGO_URI="..."
export JWT_SECRET="..."
export VIDEO_FILES_DIR="/absolute/path/to/public/video"  # optional (default: ./public/video)
export VIDEO_SESSION_MAX_AGE_SECONDS="28800"             # optional (default: 8h)
uvicorn python_video_server.server:app --host 0.0.0.0 --port 8000

HTTPS (Let’s Encrypt, Python-only)

This server can be served over HTTPS by running uvicorn with --ssl-certfile and --ssl-keyfile. To obtain/renew a trusted cert from Let’s Encrypt without installing system certbot, this repo includes a small wrapper that uses the certbot Python package.

1) Issue a certificate (HTTP-01 standalone)

Requirements:

• Your domain’s DNS A/AAAA records must point to this machine.
• Port 80 must be reachable from the internet for the ACME challenge.

python3 -m pip install -r python_video_server/requirements.txt

# Staging by default (recommended first). Add --production when it works.
sudo -E python3 -m python_video_server.letsencrypt certonly \
  --email [email protected] \
  --domains example.com,www.example.com

1b) Issue a certificate (DNS-01 manual TXT record — no port 80, no root)

If your host already uses port 80 (or you don't have permission to bind it), use DNS-01. This does not require any inbound ports on the machine, but you must be able to edit DNS for the domain.

python3 -m pip install -r python_video_server/requirements.txt

# Add --production when staging works.
python3 -m python_video_server.letsencrypt certonly \
  --challenge dns \
  --email [email protected] \
  --domains example.com,www.example.com

During issuance, certbot will prompt you to create a TXT record like:

• Name: _acme-challenge.example.com
• Type: TXT
• Value: (a token certbot prints)

After it propagates, press Enter and certbot will continue.

If you run into a situation where the prompt/token only shows up in logs, you can try the hook-based mode:

python3 -m python_video_server.letsencrypt certonly \
  --challenge dns \
  --dns-hooks \
  --email [email protected] \
  --domains example.com,www.example.com

Certificates will be written under:

• python_video_server/certs/config/live/<primary-domain>/fullchain.pem
• python_video_server/certs/config/live/<primary-domain>/privkey.pem

2) Run the video server on 443 with TLS

sudo -E uvicorn python_video_server.server:app --host 0.0.0.0 --port 443 \
  --ssl-certfile python_video_server/certs/config/live/example.com/fullchain.pem \
  --ssl-keyfile  python_video_server/certs/config/live/example.com/privkey.pem

Notes:

• Binding to ports 80/443 usually requires sudo (or a reverse proxy / port forwarding).
• If you’re behind a proxy/ingress, keep sending X-Forwarded-Proto: https so /api/video/session sets Secure cookies correctly.

3) Renew certificates

# Dry-run renewal (safe)
sudo -E python3 -m python_video_server.letsencrypt renew --dry-run

# Actual renew (typically run via cron/systemd timer)
sudo -E python3 -m python_video_server.letsencrypt renew --production

Endpoints

• POST /api/video/session
  Sets video_auth cookie (send Authorization: Bearer <token>).

• GET|HEAD /api/video/{movieId}
  Streams the movie file (supports Range: bytes=...).

• GET /healthz
