- Switch OBS output to RTMP; add FFmpeg AAC->Opus transcoding via MediaMTX runOnReady so WebRTC can carry audio (WebRTC requires Opus, not AAC) - Enable RTSP on localhost so FFmpeg reads game path without publisher conflict; viewers connect to game-opus path (H264+Opus) - Fix WHEP/HLS path prefix stripping in NPM advanced config; move all custom locations (/whep, /hls, /v3) out of NPM GUI and into advanced conf so trailing-slash proxy_pass correctly strips prefixes before hitting MediaMTX - Fix MediaMTX API port 49997->19997 (49997 was in Windows ephemeral range) - Add /status proxy endpoint to OBS HTTP server so frontend can poll stream readiness without hitting /v3/ through NPM where auth_request blocked it - Fix authInternalUsers: split publish (localhost only) from read (any IP) so WHEP viewers are not challenged with Basic Auth by MediaMTX - Remove muted attribute from video element; show unmute/play button on autoplay block so viewers get audio after one click - Fix webrtcAdditionalHosts to include LAN IP 192.168.50.254 - Fix hlsAllowOrigin->hlsAllowOrigins deprecation warning - Move MediaMTX/HTTP server startup to script_load (not streaming started) so MediaMTX is ready before OBS attempts RTMP connection - Log MediaMTX output to bin/mediamtx.log for easier debugging Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# Nginx Proxy Manager setup
|
|
|
|
Configures NPM to:
|
|
|
|
1. Serve `https://stream.hetherman.cloud` with TLS + Authentik forward auth,
|
|
reverse-proxying HTTP traffic to the Windows gaming PC.
|
|
2. Forward public UDP 48189 (WebRTC media) to the gaming PC via an NPM
|
|
**Stream** (L4 UDP proxy).
|
|
|
|
Replace `<PC-LAN-IP>` with the LAN IP of the Windows gaming PC
|
|
(e.g., `192.168.50.10`).
|
|
|
|
## 1. DNS
|
|
|
|
Create an A / CNAME record for `stream.hetherman.cloud` pointing to the same
|
|
DDNS hostname / public IP your other NPM-hosted services use.
|
|
|
|
## 2. Router port forwarding
|
|
|
|
Make sure your router forwards these to NPM (not to the PC directly):
|
|
|
|
| Proto | External port | Internal target |
|
|
|-------|--------------|-------------------|
|
|
| TCP | 443 | NPM host, 443 |
|
|
| UDP | 48189 | NPM host, 48189 |
|
|
|
|
(TCP 443 is probably already forwarded for your other services; UDP 48189 is
|
|
the new one for this app.)
|
|
|
|
## 3. NPM Proxy Host (HTTP)
|
|
|
|
In NPM, **Hosts -> Proxy Hosts -> Add Proxy Host**.
|
|
|
|
**Details tab:**
|
|
|
|
| Field | Value |
|
|
|------------------|------------------------------------|
|
|
| Domain Names | `stream.hetherman.cloud` |
|
|
| Scheme | `http` |
|
|
| Forward Hostname | `<PC-LAN-IP>` |
|
|
| Forward Port | `48080` |
|
|
| Cache Assets | off |
|
|
| Block Common Exploits | on |
|
|
| Websockets Support | **on** (WebRTC signaling works without this, but it costs nothing) |
|
|
|
|
**Custom locations tab:** add three entries so WHEP, HLS, and the MediaMTX
|
|
API are reverse-proxied to the right MediaMTX ports (and inherit the same
|
|
forward-auth gating).
|
|
|
|
| Location | Scheme | Forward Hostname | Forward Port |
|
|
|----------|--------|------------------|--------------|
|
|
| `/whep` | `http` | `<PC-LAN-IP>` | `48889` |
|
|
| `/hls` | `http` | `<PC-LAN-IP>` | `48888` |
|
|
| `/v3` | `http` | `<PC-LAN-IP>` | `19997` |
|
|
|
|
**SSL tab:**
|
|
|
|
- SSL Certificate: **Request a new SSL Certificate with Let's Encrypt**
|
|
- Force SSL: **on**
|
|
- HTTP/2 Support: **on**
|
|
- HSTS Enabled: optional
|
|
|
|
**Advanced tab:** paste the entire contents of
|
|
[`config/npm-advanced.conf`](../config/npm-advanced.conf). This installs the
|
|
Authentik forward-auth subrequest and the sign-in redirect.
|
|
|
|
Save the proxy host. Wait for the Let's Encrypt certificate to be issued.
|
|
|
|
## 4. NPM Stream (UDP L4 proxy)
|
|
|
|
In NPM, **Hosts -> Streams -> Add Stream**.
|
|
|
|
| Field | Value |
|
|
|-------------------|---------------|
|
|
| Incoming Port | `48189` |
|
|
| Forward Host | `<PC-LAN-IP>` |
|
|
| Forward Port | `48189` |
|
|
| TCP | **off** |
|
|
| UDP | **on** |
|
|
|
|
Save. NPM (nginx `stream` module) now forwards public UDP 48189 to MediaMTX
|
|
on the gaming PC. This is the path WebRTC media takes after ICE negotiation.
|
|
|
|
## 5. Verify
|
|
|
|
1. **HTTP + auth:** from an incognito browser on a different network, visit
|
|
`https://stream.hetherman.cloud`. You should be redirected to
|
|
`auth.hetherman.cloud` to log in. Log in as a `stream-viewers` member -
|
|
you should land back at the stream page (video container + "Stream
|
|
offline" overlay, assuming you haven't started OBS yet).
|
|
2. **Certificate:** the padlock icon should show the Let's Encrypt cert you
|
|
requested.
|
|
3. **/whep, /hls, /v3:** once you start streaming in OBS, open DevTools on
|
|
the stream page and confirm requests to `/whep/game/whep`,
|
|
`/hls/game/index.m3u8`, and `/v3/paths/get/game` all return 200 (and not
|
|
401/302).
|
|
4. **UDP stream:** with OBS streaming, tail the NPM container logs - you
|
|
should see entries from the stream module for UDP connections on 48189.
|
|
Alternatively, from the NPM host run
|
|
`tcpdump -n -i any udp port 48189` and confirm packets flow while a
|
|
viewer is connected.
