Stream to 3D — Streaming first checks

Use this page if streaming doesn’t play on your target device/player. It’s a symptom-first checklist designed to get you to a working stream quickly.

For the full streaming guide (protocols, examples, Kodi, etc), see Stream to 3D - Streaming.

Quick check (most problems)

  1. Start with HTTP streaming for best compatibility.
  2. Copy the exact stream URL shown in Stream to 3D (Settings summary).
  3. Test it locally first (same PC) in VLC.
  4. If it works locally but not on the device: check network/VPN/firewall.
  5. On the client/player, select the correct 3D layout (SBS vs TB/OU; Half vs Full) to match Stream to 3D output.

Local test (same PC)

Before debugging the network, verify that Stream to 3D is producing a playable stream:

  1. Start streaming in Stream to 3D.
  2. On the same PC, open the stream URL in VLC.
  3. If it fails locally, the issue is usually configuration/tools rather than the network.

Useful references:

Network / VPN / firewall

  • Make sure the client device is on the same LAN/Wi‑Fi as the PC running Stream to 3D.
  • Temporarily disable VPNs (on either side) to rule out routing issues.
  • Check Windows Firewall rules for Stream to 3D and your chosen protocol/port.

Protocol notes (HTTP vs RTSP/RTP/UDP)

  • HTTP is the default and most widely supported.
  • RTSP requires a server (e.g. MediaMTX) running while you stream. With defaults, it can be as simple as downloading MediaMTX for Windows and running mediamtx.exe.
  • For background and trade-offs, see Streaming protocols overview.

Client/player compatibility

  • Different players/devices support different protocols and containers. If one player fails, test the same URL in another client.
  • For Kodi-specific setup, see Streaming with Kodi media player.
  • If you can play the stream but it looks like a “double image”, you likely need to enable the correct 3D mode in the client (SBS vs TB/OU; Half vs Full).

Subtitles

Subtitles are only supported over HTTP streaming.

Before contacting support

To get the fastest resolution, include:

  • Your store (Steam/Gumroad/Itch/etc) and Stream to 3D version.
  • The protocol you’re using (HTTP/RTSP/etc) and the exact stream URL.
  • Whether the stream plays locally on the same PC.
  • Logs from Logs & Diagnostics.
