FFmpeg is a versatile open-source tool for encoding video files and performing basic editing operations such as stitching, cropping, and resizing. You probably know it can run from the terminal, but did you know it can also be invoked from an application in Node. Would you prefer to use an API rather than managing your own server infrastructure? Better yet, it's less expensive than hosting your own video servers. Make sure you install the ffmpeg-static and ffmpeg-fluent NPM packages first. The ffmpeg-static package provides a static build of FFmpeg, so you don't need to worry about installing it manually on the machine where you will deploy your application, and ffmpeg-fluent gives us a simple interface to run FFmpeg commands from JavaScript. In order to extract audio from a video file and store it as an MP3, we can use the following code:. This is how you can remove the audio track from a video without re-encoding. This operation is quite fast, because it doesn't have to process the video. It just copies the video stream but not the audio:. How to use FFmpeg in Node. This tutorial will show you how to use the FFmpeg from a Node.

This library abstracts the complex command-line usage of ffmpeg into a fluent, easy to use node. In order to be able to use this module, make sure you have ffmpeg installed on your system including all necessary encoding libraries like libmp3lame or libx Now including input streaming support means you can convert on-the-fly using an input- and an outputstream! To run unit tests, make sure have mocha installed on your system registered as devDependency in npm config. You find a lot of usage examples including a real-time streaming example using flowplayer and express! You have to supply an config object to the constructor containing at least the input source either a ReadableStream or a filepath. Since ffmpeg does not support dynamic sizing of your movies, fluent-ffmpeg can do this job for you using it's internal metadata-discovery. The following size formats are allowed to be passed to withSize :.

Please ensure first that you know how to achieve what you want on command line. If you don't, have a look at the ffmpeg documentation and ask the ffmpeg community first, as you're far more likely to get an appropriate answer there. When you know how to achieve your goal on command line and don't know how to translate it to fluent-ffmpeg calls, please ensure that you've read the documentation first. If you find some command line switch that has no matching fluent-ffmpeg method, you can use the inputOptions and outputOptions method instead. If you can't find how to do what you want, feel free to create an issue. Beware though this is not the most appropriate place to talk about ffmpeg usage try their mailing list or irc channels instead. Please ensure that you added handlers for both the end and error handlers.

You can still access the code and documentation for fluent-ffmpeg 1. How to seek a transcoded video over HTTP? IvanMMM commented Sep 15, If it is present, it will be passed ffmpeg output stream pipe method. Each filter pased to this method can be either a filter string eg. Filter specifications may be either plain ffmpeg filter strings eg. Note that calls to aspect are ignored when size has been called with a fixed width and height or a percentage, and also when size has not been called at all. If you intend to encode FLV videos, you must have either flvtool2 or flvmeta installed and in your PATH or fluent-ffmpeg won't be able to produce streamable output files. This method allows passing any output-related option to ffmpeg. Sorry, something went wrong. Would you prefer to use an API rather than managing your own server infrastructure? The following methods enable passing input-related options to ffmpeg. Each of these methods apply on the last input added including the one passed to the constructor, if any. Last publish 7 years ago. Note that percent can be very inaccurate, as the only progress information fluent-ffmpeg gets from ffmpeg is the total number of frames written and the corresponding duration.

Already have an account? It only has sense when processing has started. You can create clones of an FfmpegCommand instance by calling the clone method. There's a bunch of codec-specific options that make the format streamable, you should look in the ffmpeg docs. So it will be easier just to write temp file for now and read it after.
