mParams.mPlaybackRate should be updated after store mPlayDuration

-----------------------------------------------------------------

I can't see how that will make a difference. Can you elaborate it?
http://searchfox.org/mozilla-central/source/dom/media/mediasink/AudioSinkWrapper.cpp#133
GetVideoPosition(now) generate timestamp and store in mPlayDuration;

http://searchfox.org/mozilla-central/source/dom/media/mediasink/AudioSinkWrapper.cpp#67
but GetVideoPosition() use mParams.mPlaybackRate to calculate it.
Therefore, we should use old playback rate to generate it.

Please add comments why mParams.mPlaybackRate should be updated after the call to GetVideoPosition().
