What is Spout video routing
Spout is a Windows video routing library that enables multiple applications to stream video to one another. It operates directly on the graphics card, making it incredibly fast. Spout is popular for streaming video from applications like Resolume Arena, MadMapper, TouchDesigner, and many others.
How to enable Spout in Resolume Arena
The setup is straightforward. Go to the Output menu and enable Texture Sharing (Spout). A green dot indicator will confirm that Spout is enabled and actively sending video.
How to use Spout in LED Strip Studio
Spout functions as another video layer in LED Strip Studio video scenes. To use it:
- Add a new video scene
- Add a new layer called Spout
- Select from the list of available Spout streams
- LED Strip Studio will immediately start receiving and displaying the video content on your mapping
Since Spout is just another video layer type, you can use it in music-synchronized shows or activate multiple Spout streams simultaneously.
Spout Stream Not Working in LED Strip Studio?
On dual-graphics computers (typically notebooks), Spout can encounter issues. The sender and receiver software must run on the same graphics card. Since Windows manages graphics card allocation by default, and LED Strip Studio is not demanding, it may run on the slower graphics card.
To ensure both applications run on the same graphics card:
- Open Display Settings in Windows
- Go to System → Display → Graphics Settings
- Add the application manually and specify which graphics card it should use
- Typically, run both LED Strip Studio and Arena on the high-performance graphics card
Performance
The benefit of using Spout video routing is its simplicity and performance. “Once enabled, it just works seamlessly, with no noticeable delay between the frames” displayed in Resolume Arena and LED Strip Studio. While video mapping software often supports direct Art-Net mapping to LEDs, performance can suffer.
LED Strip Studio software with LEC3 devices and advanced mapping capabilities combined with Spout video delivery provides superior performance. This setup handles up to 200,000 individual RGB pixels without issues, thanks to real-time data compression between LED Strip Studio and LEC3 devices.
