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 This is the documentation for fluent-ffmpeg 2. You can still access the code and documentation for fluent-ffmpeg 1. You will find a lot of usage examples including a real-time streaming example using flowplayer and express! It may work with previous versions but several features won't be available and the library is not tested with lower versions anylonger.

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. Frames are stored as frame You might also like these tutorials Whether you prefer code or no-code, we have a wide range of guides on video automation. View all tutorials.

Can be called with or without the 'new' operator, and the 'input' parameter may be specified as 'options. Calling this method will override any previously set filtergraph, but you can set as many filters as needed in one call. Split video into RGB channels and output a 3x1 video with channels side to side. When passing a single string or an array, each string containing two words is split eg. This is not the case when passing more than one argument. Also switches "current input", that is the input that will be affected by subsequent input-related methods. This method is useful when you want to process the same input multiple times. It returns a new FfmpegCommand instance with the exact same options. All options set after the clone call will only be applied to the instance it has been called on.

There are a few caveats with this implementation, though:. Last publish 7 years ago. Depending on your ffmpeg version or if you use avconv instead other keys may be present, for example:. Jump to bottom. This method is useful when converting an input with non-square pixels to an output format that does not support non-square pixels eg. Package Sidebar Install npm i fluent-ffmpeg. Use the input and mergeToFile methods on a command to concatenate multiple inputs to a single output file. This is the documentation for fluent-ffmpeg 2. Use the screenshots method to extract one or several thumbnails and save them as PNG files. Make sure to add tests for your features and bugfixes and update the documentation see below before submitting your code! Each of these methods apply on the last input added including the one passed to the constructor, if any. The best way to have a constant video bitrate without losing too much quality is to use 2-pass encoding see Fffmpeg documentation. Adding an output switches the "current output" of the command, so that any fluent-ffmpeg method that applies to an output is indeed applied to the last output added.

The output mapping parameter specifies which stream s to include in the output from the filtergraph. If you want to add new features or change the API, please submit an issue first to make sure no one else is already working on the same thing and discuss the implementation and API details with maintainers and users by creating an issue. Note: the stream method is actually syntactic sugar for calling both output and run. License MIT. This method enforces a specific output aspect ratio. Skip to content. To run unit tests, first make sure you installed npm dependencies run npm install. This method fixes a quality factor for the audio codec VBR encoding.
