Audio & Video Creation, Modification, Conversion and More!

This sub-section of the wiki contains all kinds of information related to audio and video creation, modification, conversion, and other related info I've discovered and implimented over the years, and will continue to accumulate information as I discover more ways to work with audio and video. I will try to add stuff as I need to use it as well, as I find this a great way to document things I have had to figure out myself!

Miscelaneous Tools and Commands for Creating, Modifying and Converting Audio and Video Files

FFMPEG - The Swiss Army Knife of Audio & Video Processing!

This one tool, ffmpeg, is probably the most useful and versatile audio and video processing tool used from the command-line, as I can't even think of anything audio and/or video related that it can't do!

The FFMPEG tool consists of "ffmpeg" itself, along with a straight command-line player, "ffplay", and a tool to probe an audio and/or video source, file, etc., for it's details about the video and audio codecs, formats, quality, size and muchmore that it consists of, the "ffprobe" tool.

The "ffplay" tools is pretty straight forward when it comes to playing a file from the command line. Here's an example of how to play a local file:
