FFmpeg
FFmpeg is a software to manipulate audio and video files. FFprobe is a software to gather information from multimedia streams and prints it in human- and machine-readable fashion.
Install FFmpeg and FFprobe on a Scalingo Application
To install FFmpeg and FFprobe on a Scalingo application, you need to make use of the APT buildpack. This buildpack should be used as part of a multi-buildpack.
Add the .buildpacks file
First you need to create a .buildpacks file at the root of your project.
Then add the apt buildpack on the first line:
echo "https://github.com/Scalingo/apt-buildpack" > .buildpacks
After the apt buildpack, add the buildpack of the technology that your
application use.
For example, for a PHP application you would need to add:
echo "https://github.com/Scalingo/php-buildpack" >> .buildpacks
In the end, the .buildpacks file should looks like this:
https://github.com/Scalingo/apt-buildpack
https://github.com/Scalingo/php-buildpack
Add the Aptfile
You need to instruct the APT buildpack to install the ffmpeg package.
So you need to create a Aptfile at the root of your project with the following content:
ffmpeg
Add the LD_LIBRARY_PATH environment variable
You also need to define the environment variable LD_LIBRARY_PATH:
scalingo --app my-app env-set LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/app/.apt/usr/lib/x86_64-linux-gnu/pulseaudio:/app/.apt/usr/lib/x86_64-linux-gnu/blas:/app/.apt/usr/lib/x86_64-linux-gnu/lapack'
Trigger a new deployment
Commit .buildpacks and Aptfile files, then redeploy your application.
Check that FFmpeg and FFprobe are installed
You can make sure that FFmpeg and FFprobe are installed by running a one-off container:
$ scalingo --app my-app run bash
[00:00] Scalingo ~ $ ffmpeg
