The library, available on npm, generates the FFmpeg commands for us and executes them. under a wide variety of build environments, machine architectures, and configurations.īoasting such an impressive resume, FFmpeg is the perfect choice for video manipulation done from inside of the program, able to run in many different environments.įFmpeg is accessible through CLI, but the framework can be easily controlled through the node-fluent-ffmpeg library. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. No matter if they were designed by some standards committee, the community or a corporation. It supports the most obscure ancient formats up to the cutting edge. In the documentation, we read:įFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. Manipulating a video with Node.js itself would be extremely hard, so instead we are going to use the most popular video manipulation tool: FFmpeg.

YouTube, for instance, plays a 3- to 4-second excerpt from a video whenever users hover over its thumbnail. Generating video previews with Node.js and FFmpegĮvery website that deals with video streaming in any way has a way of showing a short preview of a video without actually playing it.
