The input file must be publicly available on a web server since the container doesn’t have access to the local file system.You should be aware of 2 caveats by using FFmpeg from a container: That’s it! $ docker run opencoconut/ffmpeg -i -f webm -c:v libvpx -c:a libvorbis - > test.webm Instead of using the ffmpeg command line, you call docker to run the opencoconut/ffmpeg image in a container. Once Docker is properly setup, it is pretty straightforward to use the FFmpeg image. If you don’t have Docker installed yet, follow this guide. 0.100 configuration: -enable-version3 -enable-gpl -enable-nonfree -enable-small -enable-libmp3lame -enable-libx264 -enable-libx265 -enable-libvpx -enable-libtheora -enable-libvorbis -enable-libopus -enable-libass -enable-libwebp -enable-librtmp -enable-postproc -enable-avresample -enable-libfreetype -enable-openssl -disable-debug How to use FFmpeg with Docker Here is the FFmpeg build configuration used in this image: ffmpeg version 3.0 Copyright (c) 2000-2016 the FFmpeg developers built with gcc 5.3.0 (Alpine 5.3.0) configuration: -enable-version3 -enable-gpl -enable-nonfree -enable-small -enable-libmp3lame -enable-libx264 -enable-libx265 -enable-libvpx -enable-libtheora -enable-libvorbis -enable-libopus -enable-libass -enable-libwebp -enable-librtmp -enable-postproc -enable-avresample -enable-libfreetype -enable-openssl -disable-debug libavutil 55. So I choose Alpine Linux which is a lightweight Linux distribution, and I ended up with an image of 106MB only. You have to compile it which implies that you need to install a ton of dependencies and have a development environment setup! I’ve been doing this for a decade and it’s not that simple.Ī typical FFmpeg image on Docker Hub is +350MB and I wanted it to be as small as possible. The problem with FFmpeg is that it is not easy to install. FFmpeg is a free software project and is the leading software for everything related to multimedia like video encoding, streaming and muxing.
