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.

First we use the code below to access the metadata. I am not sure what version of fluent-ffmpeg you are using, nor have I tested this on a Windows platform I just started using fluent-ffmpeg today and the solution I am providing is based on my observations. So is there any solid way to find out if the file is audio only or video from the metadata? Or should I use ffmpeg commandline to find it out? I am not why there is a 'resolution' since it is a pure audio file. mp3 file through fluent-ffmpeg,the result looks something like this: video: But some strange things happened that this doesn't work on Windows platform (I have tried Windows 7 64bit and Windows 2008) using the latest ffmpeg. if both resolution.w and resolution.h are 0, then this file is an audio. I have tried on Mac OS to use the 'resolution' attribute in the metadata to tell if a file is audio only or video, i.e. It is very good that fluent-ffmpeg provides functions to get the metadata of a video and audio file. I am using node-fluent-ffmpeg module in NodeJS.
