javascript - Remove Controls in MediaElement player. Where to add/change the code -

this basic question change or add code. want remove of controls on media element player. there information everywhere on internet in summary states.

you can control buttons appear on control bar setting {features:['playpause','backlight']} array etc...

my question go change or insert code {features: etc...

i see folders media front/players/osmplayer/player/templates etc. , there several src query-ui js folders , files.

just add features want/need in own custom mejs initialization script :

$('video,audio').mediaelementplayer({    features:['playpause','progress','volume'],    alwaysshowcontrols: false });
