Force your users to watch youtube in 240p

how to force your users to watch youtube in 240p?

is it a script or a layer7 + mangle ?


i want my users when they go to watch anything on youtube to watch it at 240p then they can choose from the youtube drop down menu button any other quality !

or

just redirect every high quality videos on youtube to 240p quality

as far as i know when i open mikrotik system log i find each time i change the video quality it starts with these different line codes

1080p
