How can I make sure that FFmpeg is on system path?

Question

I have been trying to deploy my app through Github with automatic update. I’ve run into a problem where if I try to use my app it will error out with FFmpegNotFound (One of the packages I’m using requires it). I have tried to add it to the environment variables as well as manually adding it both with ‘export’ on Bash and in ‘~/.bashrc’ but neither seem to work. Also anything I do is reset every time the system rebuilds so I’m wondering if there’s anything I can do that will fix this issue and be permanent.

Hello,

If you are talking about a Droplet rather than App platform, you can use the full system path. Once you are inside your Droplet type in :

which ffmpeg

As for an App platform, this might not be the prettiest solution but I managed to do this with a run_command and downloading ffmpeg manually and adding it to the path in line.

You can probably do this in a script setup.sh or similar but for simplicties sake I did it with the sample-php app and inline with the command that starts it.

Here was my run_command:

run_command: cd && mkdir -p bin/ffmpeg-build && pushd bin/ffmpeg-build && wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-amd64-static.tar.xz
    && tar xf ffmpeg-git-amd64-static.tar.xz && cd ffmpeg-git-20220910-amd64-static
    && mv * ../../ && popd && rm -rf ./bin/ffmpeg-build && export PATH=$PATH:/workspace/bin
    && heroku-php-apache2

The instructions on how to install I found here: https://gist.github.com/jmsaavedra/62bbcd20d40bcddf27ac

and I had to modify them because the link presented in the gist 404’ed. I found the links to download ffmpeg from: https://ffmpeg.org/download.html

Which when you click the static binaries it redirects you to https://johnvansickle.com/ffmpeg/.
