Connect to Barco Clickshare via Linux

The USB-C Clickshare is just an external Network card.

Get the password of the Clickshare network and connect to it.

Create a virtual Wifi card so that you can still access the web:

Replace wlan0 by your own card:

sudo iw dev wlan0 interface add wlanvirt type station

1. If you are creating the image

1.1. Create the Live stick

Install DUS/MKUSB :

sudo add-apt-repository ppa:mkusb/ppa
sudo apt update
sudo apt install mkusb mkusb-nox usb-pack-efi

Generating GPX by hand and Geocoding pictures with GPicSync

This reminder applies if you have pictures that need geocoding (e.g. to be uploaded on Mapillary) but you have no GPX file. We assume you have captured pictures alonside a path from a start point to an en point and that you are able to redraw this path precisely on a map. The first step will be to generate manually a GPX file, then to synchronize it with your pictures thanks to timestamps, and then GPicSync will geocode.

Download GPicSync, install dependencies and make sure you can run the GUI with Python 2, e.g. python2 gpicsync-GUI.py
Draw you actual path on https://geojson.net/ with these recommandations:

Place points at every key location, e.g. when you turned or passed in front of a remarkable location that is easy to distinguish visually on pictures (building, square, monuments...)
Find a good compromise between numerous points (= very accurate pat

Problem

AppName has conflicting provisioning settings.
AppName is automatically signed for development, but a conflicting code signing identity iPhone Distribution has been manually specified. Set the code signing identity value to iPhone Developer in the build settings editor, or switch to manual signing in the project editor.`

Solution

In left section, double click the project name to open the project editor
In left section, Select the project (AF), select Build settings, then All and Combined
In Signing section select iOS Developer for all entries within Code Signing identity
In left section, Select the target (AF), select Build settings, then All and Combined

Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. Since bitrate = file size / duration:

(200 MiB * 8192 [converts MiB to kBit]) / 600 seconds = ~2730 kBit/s total bitrate 2730 - 128 kBit/s (desired audio bitrate) = 2602 kBit/s video bitrate
