Re: [webrtc-pc] getSynchronizationSources (and getContriburingSources) should work for video too

@henbos [timestamp](http://w3c.github.io/webrtc-pc/#dom-rtcrtpcontributingsource-timestamp) is poorly named here: It indicates *"the most recent time of* **playout** *of media"*.

It's predicted playout time through a media element. It's ***not*** the RTP timestamp.

As @fippo [mentions](https://github.com/w3c/webrtc-pc/issues/1983#issuecomment-421010310): this API was designed specifically for audio bars per participant. *getStats* was deemed too slow for this purpose, which is why these synchronous methods exists.

Are there compelling use-cases for runtime playout time estimation of video?
