Select streams extracts a contiguous range of streams from a video bundle.
What it does#
It has no parameters. It takes a bundle of 1 to 8 streams on video and outputs the chosen range. The range is set the same way as on the audio Select channels: the node's channel settings name the first stream and how many streams to keep, and the range must fit inside the incoming bundle.
When to use it#
Use it to split one stream out of a bundle made with Combine streams.
Ports#
| Port | Direction | Signal | Lanes |
|---|---|---|---|
video | Input | Video | Inferred from the cable |
video | Output | Video | Inferred from the cable |
Parameters#
This node has no numeric parameters.
This node has no parameters.
Tips#
- Streams count from 1.
- Video needs the browser's WebGPU video engine. The Player and exports do not run video yet and report it unavailable. To see a video output, bind a live Screen in the Frame to it.
