==YouTube Video on the Kiosk==
Google Slides makes it pretty easy to embed a YouTube video in a slide. Some tips to get them working on the kiosk:
1. Get the URL of the youtube video you want to display, eg. [https://www.youtube.com/watch?v=B6suC_pPfqg https://www.youtube.com/watch?v=B6suC_pPfqg] . (NB: The "watch?v=" seems to be critical).
2. If you want closed captions /subtitles on the kiosk (because you probably won't want sound playing in the hallway), the captions HAVE TO BE EMBEDDED in the video: there does NOT appear to be way to have the youtube captions/subtitles displayed in the video embedded in a Google Slide without user interaction.
2. In Google Slides, set the Video Format -> Video playback -> check "Autoplay", so that the video plays automatically when the slide presentation starts (not sure if "Mute" needs to be checked)
3. On the Raspberry PI, you need to run the desktop version of Chrome to Preferences (chrome://settings) to Advanced -> Privacy and Security -> Site Settings -> Sound -> Allow -> Add -> add your kiosk site (eg. https://www.bio.fsu.edu/grad/kiosk), to whitelist your site so that videos will autoplay.
IMPORTANT: as far as we can tell, there is NO way to use the command line to set Chrome to autoplay a video inside a Google Slides inside an iframe, which is how the kiosk displays the slides. That means that the kiosk.sh script can't set this up for you, you have to use the desktop version of Chrome "in the real" to make the setting.
