You can watch entire videos using gstreamer and aasink.

gst-launch-1.0 filesrc location=my video.webm ! videoconvert ! aasink

This is a great way to watch videos inside your terminal.

Or, a terrible way to watch videos, I suppose, it depends on how much you like ASCII art.

I remember VLC (the video player) having an output option for playing a video as ascii art. I could actually recognize some of the items in the scene.
