I’m started a new position at Logitech, as Solution Engineer. In my role I need to present and “sell” the fantastic Logitech Video portfolio. In order to demonstrate the devices, I would need to be able to showcase each product from remote. As still a lot of customers like to work from remote.

…This is how it could/should look like when I’m done..well then I will just add more..

Wiring

The idea behind the setup is the present the portfolio of Logitech to my customers, so I would need to be able to demonstrate the devices and capabilities. As I don’t have and don’t want to plater the wall with screens, I decided to use a HDMI Matrix and ATEM to mix all together.

Each Logitech Camera has two HDMI-out and a HDMI-in. This makes three signals to process. As I can share the content source for all cameras, I only need a HDMI-splitter function. Further I had troubles with the HDMI in on the ATEM, which seamed to loose the sync on reboot of the cameras. The ATEN (not ATEM) 8×8 Matrix works fine with the cameras, as it’s emulating EDID which fixes the sync issue (at least this is what I see/think).

On Port 1-7 I have each the two outputs of the cameras, and port 8 is the input of the PC for the desktop sharing.

From the ATEN to the ATEM, I’ve routed three cables, normally this would be screen 1, screen 2 and the content. Since I can control the Matrix and the ATEM from the StreamDeck, I can switch any camera output to screen.

ATEN 8x8 Matrix In	Out	Port	ATEM mini Extreme In	Out

Control

I use a Stream-Deck XL together with the companion app to control all the gear. I have about 8 Pages with buttons configured, but since I re-use many buttons over and over again, I have used some pages to park these, and only place references to the page in question. So when I change the source button, all others change automatically.

Also many colors change based on feedback of states, so this really makes is a lot more robust and flexible to design. I have by far not reached the end of my exploration in the Companion App, but I think I’m pretty good by now 😉

Here you see an example of the Matrix I’ve built in the Companion App:

On the button press action, I set the Matrix, and the feedback action is to change the background to the active color, red, if the input is enabled. This way I always see which input is active, regardless where I changed the Matrix.

Configuration

Raspberry Pi4

On the Rasbperry Pi4 I run the custom build from Bitfocus, this takes care of all the updates for the companion app.

Update Companion App to 2.2, which is needed for the SX10 integration

companion-update

The Raspi4 has two HDMI outputs, which I would like to use for different tasks,

One screen shall be used to play video content, especially together with the ATEM SouperSource feature, I can use this as animated background
Screen two shall be used for the top-town webcam. This way I can capture what’s on my desk, for example the Logitech-Tab

Configuration on the Raspi4:

mplayer playing on the 2nd screen in Full-HD, and rotated by 180°:

pi@raspi4:~ $ alias webcam="mplayer -fps 30 tv:// -tv driver=v4l2:device=/dev/video1:width=1280:height=720 -xineramascreen 1 -fs -vf-add flip -vf-add mirror"

Start VLC automatically

alias vlclogi="vlc --fullscreen Raspi4/LogiBG_Colors.xspf"

nano /home/pi/.config/autostart/vlc.desktop
[Desktop Entry]
Type=Application
Name=VLC
Exec=vlc --fullscreen Raspi4/LogiBG_Colors.xspf

nano /home/pi/.config/autostart/webcam.desktop

Exec=mplayer -fps 30 tv:// -tv driver=v4l2:device=/dev/video0:width=1280:height=720 -xineramascreen 1 -fs -vf-add flip -vf-add mirror

Sty tuned.. more to come 🙂
