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.

Can be called with or without the 'new' operator, and the 'input' parameter may be specified as 'options.

This method is mainly useful when producing multiple outputs otherwise the save or stream methods are more straightforward. Sending a signal that terminates the process will result in the error event being emitted. Seeks an input and only start decoding at given time offset.

Sets the target video bitrate in kbps. Use the input and mergeToFile methods on a command to concatenate multiple inputs to a single output file. They should be mostly compatible, but should you encounter any issue, you may want to use the real ffmpeg instead. In order to extract audio from a video file and store it as an MP3, we can use the following code:.
