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:
[jamie@server.dawgland.com:~/Videos]$ ffplay /home/jamie/Videos/Armagedon.mp4

The video begins to play and continues until the end or until I hit the "ESCAPE" key.
Playing a network stream using ffplay is also farily straight-forward. Here's an example:

The stream plays until the "ESCAPE" key is hit.
The "ffprobe" tool is run in the same way. Here's an example of using ffprobe on a local video file:

The main command, "ffmpeg", is where the real power lies! This one command, along with a multitude of command-line arguments, switches and options, can pretty much do it ALL when it comes to audio/video processing!!!
I will continually add more information in this one sub-section of this wiki, as I am always discovering new ways to use ffmpeg!
To start off with, here's a command I often use as I find old DVD's collecting dust and worse, scratches! Using ffmpeg, I can easily "rip" videos from old DVD's, inculding old home videos that were originally recorded using video tape recorder cameras and later converted to DVD's, as is often the case, along with old film videos converted to digital files and "burned" onto disks.
Here's an example of how I "rip" a video from a DVD while converting it to a digital .mp4(MPEG) files which can then be shared, uploaded to the cloud, or otherwise better utilize the videos.

Although there was a minor error displayed during the conversion process, the end result turned out perfect, as they usually always do! Of course, be sure to use your own file names and directories.
You can even use "wild-cards", such as the "*" symbol which equals any character of any length, to select and convert many files in the same directory all at the same time, as shown here ripping all of the videos from an entire DVD:
