User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151029151421
Steps to reproduce:
1. Use an MSE-based player that supports using TrickMode adaptations for video (see Trick Mode Support in http://dashif.org/w/2015/04/DASH-IF-IOP-v3.0.pdf ) for fast forward playback to play this stream - http://de9b7h88wgj5l.cloudfront.net/stage/set5/dash_mbr/set5_dash_mbr_tp.mpd.
Or
1.Use an MSE-based player to play this stream - http://de9b7h88wgj5l.cloudfront.net/stage/set5/dash_mbr/set5_dash_mbr_tp.mpd.
2. Change the player to use the video adaptation with id ="3" - this is the trick mode adaptation with frameRate=1/4.
3. Set playbackRate on the video tag to 2.
Actual results:
Playback freezes. The buffer seems to have enough segments to proceed but the video does not playback.
Expected results:
Video should playback at a rate of 2. This used to work in Firefox 41.
Do you have a link to a MSE-based player to test that?

I can provide a link to the player out of band in an email, please share an email id to provide the URL. Thanks!

[User impact if declined]: playback stall
[Describe test coverage new/current, TreeHerder]: In central for a few days, lots of MSE mochitest, manual testing
[Risks and why]: Low. We should have always done it this way, a condition that was overlooked. While the risk is low, being a racy situation it could happen with YouTube.
[String/UUID change made/needed]: None
