There isn't a means to disable the video track. The motivation for the ability
to disable of video is in case the application wants to simply have audio track
playing but no video. It may be possible to hide the video but it unclear if
the associated resources are released or not. Making an explicit method makes
for a clear behavior by the browser and easier for developers to create
webpages that may need the additional resources. 

This may be required when developing web pages that overlay or cover the
fullscreen while playing a live broadcast. If the video is HD quality and uses
a large amount of processing power a the web page that may be overlayed
termporarily it may require addition graphics or cpu power. The audio may
continue to be played in order for the user to be able to track the live

An example is if live broadcast is being rendered during commercials the
end-user may want to play a game but listen to the commercials in order to know
when to turn off the game. With this approach more advanced web pages may be
supported on terminals with a reduced capacity.

The proposal is to have a similar option as text track to disable the video

Note-This proposed changed is based in discussions in W3C webTV IG - media
piping task force.
