Display a short video or GIF in the terminal. You can check out a video demonstration here. This was inspired by -- and is a much more general version of -- malav097's shell-emotions. Suggestions and pull requests are welcome.
termimation input.gif will convert the GIF into a series of images (in /tmp/),
convert those into an array of text, and display the elements of that array successively to play the animation.
This will have the same average frame rate as the input file.
Ctrl-C can be used to abort the animation.
I think jp2a gives prettier results out of the box, but both jp2a and img2txt can be thoroughly configured.
ffmpeg is probably a little bit faster and more versatile than imagemagick.
That this draws each frame starting at row 0, column 0 in your terminal in a kind of brute-force way. So, it will clobber up to the last screen-full of your scrollback buffer.
This loads the entire ASCII-art-ified animation into memory. You should only use this with short and/or low-frame-rate files. If you try to display long/high-FPS video, you'll run out of memory pretty quickly.

- coreutils
- ffmpeg (or imagemagick as a fallback)
- jp2a (or libcaca as a fallback)
