FFmpeg - command line

A complete, cross-platform solution to record, convert and stream audio and video.

To work with multimedia we can use the AMAZING tool/library called FFmpeg. Chances are you already know/use it directly or indirectly (do you use Chrome?).

It has a command line program called ffmpeg, a very simple yet powerful binary. For instance, you can convert from mp4 to the container avi just by typing the follow command:

$ ffmpeg -i input.mp4 output.avi

We just made a remuxing here, which is converting from one container to another one. Technically FFmpeg could also be doing a transcoding but we’ll talk about that later.
