vMix Snapshot Proxy

vMix has a robust API, but one key limitation of the API is that while you can tell vMix to take a snapshot of an input, it will save the image on the vMix machine but not send the image over the network.

This is a small application running on the nodejs framework to act as a proxy for those images.

The application is especially helpful in providing preview images of each input for

Installation for Advanced Users

These commands should be run on the same computer that is running vMix.

$ git clone https://github.com/jeffmikels/vmix-snapshot-proxy.git
$ cd vmix-snapshot-proxy
$ npm install

Usage

Edit the settings at the top of index.js.

Start vMix and then the proxy server...

$ node index.js

You'll see something like the following output

=====================================
Running vMix Snapshot Proxy at port 8098
Get a list of all inputs:                http://192.168.1.1:8098/
Force regen one input (0 means program): http://192.168.1.1:8098/regen/#
Force regen all inputs:                  http://192.168.1.1:8098/regen
Get input snapshot:                      http://192.168.1.1:8098/#.jpg

Getting an input snapshot sends the most recent snapshot, and queues the generation of a new one.
Snapshots take about 1 second to process
=====================================

Open a browser and visit:

http://[PROXY_IP_ADDRESS]:8098/[INPUT_NUMBER].jpg

Every time you visit that address, you will receive a new snapshot image of the selected input.
