Team Scene The team didn’t know anything about embedded systems. - Hardware background - Web Development experience “Oh! We can communicate via SSH” … “Why not to write a webserver?”

Step 2 - Remote control over the network - Remote upgrades - POST data to main server

Slide 15

Reliable (?) Almost every exception results in reboot

Step 3 - Robust application manager - Robust remote upgrades *not easy for the team

We really need to record video so we need GStreame r but not only that, we need our encoder

Slide 26

Slide 26 text

- Required omx encoder - Old Gstreamer version FAIL!

Slide 27

Slide 27 text

Stable Solution (?) - Raspbian - Docker - Omx encoder - Runtime tricks

Slide 28

Slide 28 text

This is not WORKING! we need to compile a Custom System

Slide 29

Slide 29 text

Stable Solution (again?) - Nerves 32 bits - Gstreamer - Omx encoder

Slide 30

Slide 30 text

Nerves 64 bits! - Last Linux kernel - Gstreamer - No more GPU encoder - Concurrent Encoding
