This feature gives ability for user to choose preferred video format like vimeo does.

for normal mode?

[zuf]

Yes, normal mode (for play mp4/flv files).

I mean ordinary (non HD) video.
Vimeo player has button "HD on" that switch between HD and "non-HD" video source.
For example: http://www.vimeo.com/hd

JW Player has plugin with same ability:
