Installing FFmpeg in Ubuntuįfmpeg does not come pre-installed in Ubuntu by default, so you will first have to install this program to use it. The tasks that can be performed with the aid of ffmpeg include audio file conversion, video file conversion, photo conversion, image file extraction from video files, generating videos from image files, extracting audio from video, cropping videos and photos, trimming videos, re-sizing videos, boosting volume, and creating screen recordings. There are obviously expensive tools out there that one can buy to fulfill one’s needs, but what if we could do this for free? What if a few lines of code could do almost any video-related task that you require?įfmpeg is a free and open-source video conversion, extraction, and editing tool that provides an answer to this question! What can ffmpeg not do? Almost nothing. It has become so common, in fact, that creating and editing audio and video files have become the new normal in the span of only a few decades. m4a container works on your device before releasing more degraded lossy transcodes in to the world.In the modern world, with YouTube and other social media apps as the mainstream way to view digital media, uploading videos has become a common practice. If you really do want to degrade the audio and choose mp3 for maximum compatibility, just change -c:a copy to -c:a libmp3lame -q:a 0 but I would encourage you to at least test that the copying the AAC audio in. The AAC audio format (usual in MP4s) is more efficient than MP3 so sounds better at lower bitrates, as well as having fewer problem samples and artifacts - it was designed to replace MP3 by fixing some of the flaws in the older format, and has the full industry backing of everyone that matters as well as being several International Standards, so it's widely supported on pretty much every device from the last 15-20 years. Before doing this you should know that you'll get better sound quality (as well as being quicker) if you just copy out the existing audio and remux it into a a suitable container, rather than converting the audio which always causes sound quality to deteriorate due to the way these lossy codecs discard data with each encode.
