An advanced selfie cam script, that can also take short videos and send them to telegram (which autoplays them!)

selfie_cam_advanced.py

"""
Edistyneempi palvelinskripti.
localhost:5000/photo ottaa kuvan,
localhost:5000/video ottaa lyhyen videon.
Taman jalkeen paketti lahetetaan ennalta-
maaritetylle Telegram-kanavalle.

Muokkaa muuttujat
BOT_API_TOKEN ja GROUP_ID
ennen ajamista.

>> python selfie_cam_advanced.py

huom! Videokuvan lahettaminen vaatii
GPAC-binaarit.

>> sudo apt-get update
>> sudo apt-get install gpac
