Hello, I needed to use FFmpeg in a node application, however the problem was the default FFmpeg that can be installed with the node image was too old and didn't support what I was trying to do.
There were two ways to handle this either compile FFmpeg from source, which would take a while and I really didn't want to have a long Dockerfile, not to mention the cleanup afterwards.
So I decided to copy the FFmpeg bin from the "jrottenberg/ffmpeg:4.4-alpine" into the Nodejs image. Reason being it's simpler.
To use the FFmpeg bin with the node image I changed the head of my Dockerfile like so:
FROM jrottenberg/ffmpeg:4.4-alpine AS FFmpeg FROM node:16-alpine COPY --from=FFmpeg / /
With this I was able to use FFmpeg 4.4 with the Node 16 image. I also learned something new about Docker.
Hopefully this will help me in future projects, and hopefully be of use to you.
