You can either compile it from source or find a pre-built. They should be mostly compatible, but should you encounter any issue, you may want to use the real ffmpeg instead.

Windows users: most probably ffmpeg and ffprobe will not be in your %PATH, so you must set %FFMPEG_PATH and %FFPROBE_PATH.ĭebian/Ubuntu users: the official repositories have the ffmpeg/ffprobe executable in the libav-tools package, and they are actually rebranded avconv/avprobe executables (avconv is a fork of ffmpeg). Most features should work when using avconv and avprobe instead of ffmpeg and ffprobe, but they are not officially supported at the moment. Similarly, fluent-ffmpeg will use the FFPROBE_PATH environment variable if it is set, otherwise it will attempt to call it in the PATH.

You must also have ffprobe installed (it comes with ffmpeg in most distributions).

Otherwise, it will attempt to call ffmpeg directly (so it should be in your PATH). If the FFMPEG_PATH environment variable is set, fluent-ffmpeg will use it as the full path to the ffmpeg executable. It may work with previous versions but several features won't be available (and the library is not tested with lower versions anylonger). Prerequisites ffmpeg and ffprobeįluent-ffmpeg requires ffmpeg >= 0.9 to work. You will find a lot of usage examples (including a real-time streaming example using flowplayer and express!) in the examples folder. Here is the code to try for yourself, all you need is a test.mp3 large enough that the resulting testoutput.ogg is > 3mb: var ffmpeg = require('fluent-ffmpeg') įfmpeg.$ git submodule add git:///schaermu/node-fluent-ffmpeg.git vendor/fluent-ffmpeg Usage outputOptions('-fs 3000000') isn't working for me, the file is coming back with a size of 119260428 or 119mb. Summary: I'm trying to limit output to 3mb.
