Stream to 3D Streaming Troubleshooting

Updated 19 July 2026

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)

Start with HTTP streaming for best compatibility.
Copy the exact stream URL shown in Stream to 3D (Settings summary).
Test it locally first (same PC) in VLC.
If it works locally but not on the device: check network/VPN/firewall.
On the client/player, manually select the correct 3D layout (SBS vs TB/OU; Half vs Full) to match Stream to 3D output.
If the stream plays but the views do not combine cleanly, return the player to its default or best-fit aspect ratio before changing depth settings.

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

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

Useful references:

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.

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.

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 the stream plays but looks doubled, displaced, ghosted or unexpectedly flat, manually select the matching 3D mode in the client (SBS vs TB/OU; Half vs Full) and disable additional zoom, crop or stretch.
For source video with black borders at the top and bottom, try a supported SBS output. For borders at the left and right, including padded 4:3 video, try a supported TB/OU output.
Check the streaming device's display calibration and the TV or projector's overscan or 1:1 pixel setting. Even small scaling differences can move the eye division seen by automatic 3D detection.

When the frame is divided and scaled correctly, the 3D effect should be pronounced. See Player, streaming-device and display scaling for the full diagnostic sequence.

Subtitles are only supported over HTTP streaming.
