FFMPEG.js is an amazing project and it helped me building one of my latest projects: Device Frame. It basically builds ffmpeg (with a good set of defaults to keep the size small — as small as it can be). If the default build doesn't support the filters and encoders you need, then you will need to build it yourself.
This is more of a note for me in the future, but this is what I did to get it working. (Note: I tried on macOS sierra and was getting compile errors).
sudo apt-get install automake libtool build-essential cmake
git clone firstname.lastname@example.org:Kagami/ffmpeg.js.git
git submodule init
git submodule update --recursive

./emsdk install latest
./emsdk activate latest
If there are errors with fribidi:
cd build/fribidi/ && ./bootstrap && configure
You might see errors like:
./configure: line 4255: syntax error near unexpected token `2.2' ./configure: line 4255: `LT_PREREQ(2.2)'
Make sure you have
