Dockerfile

# This dockerfile is built using the testing suite since there might be an
# important version gap between stable and testing.
# Testing/Unstable will usually have ffmpeg versions closer to other distributions.
# As of this writing:
#  - deb-multimedia's stable (Buster) has ffmpeg v4.1.6
#  - deb-multimedia's testing (Bullseye) has ffmpeg v4.3.1
