Supporting small delta play rate control for video element in Chromecast receiver app

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Setting playbackRate property of HTML video element.
2.
3.

What is the expected output? What do you see instead?

Expect to see the playback rate adjusted accordingly. But the setting is 
ignored.

What version of the product are you using? On what operating system?

Chromecast

Please provide any additional information below.

I understand supporting large play rate delta might be problematic but 10-15% 
delta would be very useful for optimizing adaptive streaming. Audio pitch 
deviation is tolerable in this range but it would be great it that was adjusted.

I would like this as well.  I have an app I am developing that is a slideshow 
with music or video streams.  I am trying to sync the AV playback between 
multiple devices and chrome on a laptop.  If I use one Chromecast as the master 
timestamp and chrome as the slave then things work fine.  But if I use two 
Chromecast or chrome as the master then the Chromecast can't adjust their 
playback rate to sync correctly.  I would be happy with 10-20% adaptability.  
Fixed playbackRate means there is no way for the Chromecast to sync cleanly 
since it also can't seek quickly in a stream to jump forward or backward to 
resync.
