HTTP adaptive streaming seems handle the advertisement and video editing, can media source 
Have API so I can change media file or real time stream in <video> element from original format to a new format just using
JS API to output to another <video> element? May use file API to output to a BLOB?

HTTP adaptive streaming is in the process of being standardised with
the MediaSource API [1]. That will allow delivery of video to all
devices, because it adapts to bandwidth and device capabilities.
