Stream to 3D Tools and Dependencies Checklist
This page helps you confirm that the supporting applications needed for your workflow are installed and detected correctly.
If you are troubleshooting something else (layout, streaming, performance), start with User FAQ & Troubleshooting.
Quick check (2 minutes)
- Open Settings → Tools and confirm your selected media player path looks correct.
- If you use Stream or Convert, confirm the encoding application is installed and detected in Settings > Tools.
- If you use VLC as your player, confirm the optional VLC playback integration is installed.
- If anything is missing, use the fixes below.
Settings → Tools (what to verify)
Many setup issues occur when a selected media player or supporting application is missing or its saved location is no longer correct.
- Media player: choose MPC-HC, PotPlayer, VLC, or Custom. The path must point to the actual 64-bit player
.exe. If the player was already installed elsewhere, use its shortcut or installation folder to locate the executable and update the path. - Encoding application (Stream/Convert): required for network streaming and file conversion. If it’s missing, re-run the installer/tools setup for your store edition.
- Libraries (optional): these improve scene/motion detection quality. If missing, Stream to 3D still runs, but conversion quality may be reduced.
Steam: re-install optional tools
If you purchased via Steam and tools/players are missing, the fastest fix is to run the optional tools installer that ships with Stream to 3D:
StreamTo3DToolsOptionalSetup.cmd
Typical location:
C:\Program Files (x86)\Steam\steamapps\common\Stream to 3D
Uninstalling and reinstalling the main Steam application does not necessarily rerun the separately installed optional-tools setup. If Stream to 3D itself is present but a player, codec or conversion tool is missing, run this repair script instead of repeatedly reinstalling the application.
VLC playback integration
VLC needs the matching optional Stream to 3D playback integration. Follow the VLC playback integration guide.
If you use MPC-HC or PotPlayer, you do not need this VLC-specific component.
Encoding and graphics drivers
- If you see a GPU encoding error or Stream to 3D tells you to update your graphics driver, update your NVIDIA/AMD driver first.
- For advanced encoding settings, see advanced streaming and conversion options.
Codec packs and players
Codec and player availability affects what files can be opened and converted. See Hardware and Software Requirements for the recommended baseline.
Third‑party tools have their own licences and are not authored by Stream to 3D.
Before contacting support
To get the fastest resolution, include:
- Your store (Steam/Gumroad/Itch/etc) and Stream to 3D version.
- A screenshot of Settings → Tools.
- Logs from Logs & Diagnostics.
