This guide will show you how to add a realtime preview of a selected scene
from OBS on your button.
Scene output to Icon event
For this we need the Scene output to Icon event event. This is a special
type of event within Touch Portal and will request a small image of the selected
scene and send it to your mobile device to show on that button.
The event has three options:
- Scene selector, you can select a specific scene or can you
can select the current active live scene or the current preview scene.
- Speed selector, you can specify here how many times per
interval you want the image to be updated. Please note that
this is a heavy functionality. The update message containing the image
are large and will have an impact on all other send messages as well.
We advise you to use a maximum of 1 frames per second to keep the Touch
Portal experience a smooth one.
- Quality selector, High will mean a larger image with more
detail but the downside is that
this generates more data and thus longer messages send to your mobile
device. This could have a negative effect on the frames per second
and on the performance of other buttons and events.
Add the event to your button and specify the settings you want. Press refresh
on your device and you will see the button showing the scene on your Touch Portal
button.
Although this action specifically is for Scenes, you can also do this for
sources in OBS. You just need to create a scene that only holds that source
and then link to that scene.
End Result
You will now have a button that shows the realtime image of the selected
scene.
