Asynchronous Source Duplication Plugin for OBS Studio

Introduction

This plugin provides a duplicated source of an asynchronous source.

Asynchronous filters cannot be applied to a scene or a group. That means you cannot have one source as two scene-items with and without the asynchronous filter.

For example, you want to have two sources; one is a video camera input and the other is the same video camera input but having a Video Delay (Async) filter to delay. However, you cannot have two separated sources that access the same video capture device.

In such case, this plugin help you to duplicate the asynchronous source.

Usage

To start to use,

1. Select the scene you want to have the duplicated source.
2. Click + at the bottom of Sources list.
3. Click Asynchronous Source Duplicator.
4. Select the name of the source that you want to duplicate.
5. Click Insert Filter to the Source button. This step will add a filter to the source you selected above.

To remove the filter,

1. Open filter dialog for the source.
2. Select Asynchronous Source Duplication Filter in the bottom of Audio/Video Filters list.
3. Click - at the bottom of Audio/Video Filters list.

Note that the filter Asynchronous Source Duplication Filter should be located at the top so that other filters won't affect the duplicated source.
