There are so many weird things that you can do with the help of a Linux system. Well, the term ‘weird’ is relative since there is a good number of geeks who consider these as ‘cool’. You may try searching ‘weird things using Linux’ to get more entries like this in this blog.
Video in ASCII model
There are different ways for doing this. Here I’m gonna describe one of the easiest ways using MPlayer. Before you proceed further please make sure that you have installed mplayer in your system. This is available in the software repository of most of the popular Linux distributions.
After installing MPlayer, issue:
mplayer -vo caca file.avi
Replace ‘file’ by the name (and path if required) of your file. The parameter –vo is used to select the video output driver. You can also use –ao to select audio output driver. We also use the caca library which is the ASCII-art library for producing output text with color (you can learn more about it in this website).
I experiment with a video file (‘Stephen Fry in America’) and obtained this:
You may try using the parameter ‘nosound’ for playing it without any sound and ‘fs’ for displaying in full screen.
You may have notice that it is not very elegant. You can improve it (not the quality!) by adding a subtitle file using the parameter ‘sub’.
And here is a set of libraries which you can try instead of caca:
