If you must offer autoplay functionality, you should make it opt-in (requiring a user to specifically enable it). However, this can be useful when creating media elements whose source will be set at a later time, under user control. See our To disable video autoplay, autoplay="false" will not work; the video will autoplay if the attribute is there in the tag at all.
