--- Downloading and compiling the source code takes a lot of time. ---
You can save time by using the static builds maintained by John Van Sickle and can be found here: https://www.johnvansickle.com/ffmpeg/. Just make sure that you download the appropriate binary depending on the processor architecture you use.
Steps below are a combination of these 2 sources:
- https://www.assetbank.co.uk/support/documentation/install/ffmpeg-debian-squeeze/ffmpeg-debian-jessie/
- http://www.jeffreythompson.org/blog/2014/11/13/installing-ffmpeg-for-raspberry-pi/

ffmpeg -encoders # test it worksDocker containers were used, so ffmpeg was not installed directly on the RPi. The docker image has been pushed to https://hub.docker.com/r/tgogos/ffmpeg/, you can save time by pulling it and then start testing... If you'd like to reproduce the whole process take a look at the section below "Download ffmpeg source code / compile"
- Raspberry Pi 3
- Host OS: Raspbian Jessie Lite image (downloaded 2016-09-23-raspbian-jessie-lite.zip from the official site)
- Docker image to start with (FROM):
resin/rpi-raspbian:jessie-20160831 - Video file: Big Buck Bunny by Blender Foundation https://www.youtube.com/watch?v=YE7VzlLtp-4
