Tapping on the scrubber will seek to a position for a second and then immediately skip to the end of the video. Still trying to debug why. I haven't been able to find any problems with the controls themselves that cause this. We do pause and play the video in quick succession before the seek happens because of how we fire click events: http://mxr.mozilla.org/mozilla-central/source/toolkit/content/widgets/videocontrols.xml#167 (this is different than what happens on desktop). Shortly after the controls receive a timeupdate event from the video itself that causes them to jump to the end.

hmm... this doesn't affect all videos, but does affect the one in the url: http://mxr.mozilla.org/mozilla-central/source/toolkit/content/widgets/videocontrols.xml#167

Whoops. that's not right. heh: http://people.mozilla.com/~nhirata/html_tp/big_buck_bunny_480p.webm

The webm file doesn't have any cues; it doesn't have an index of keyframes, so our webm code can't seek in it.

cc'ing nhirata just to make sure he knows his webm file has issues.

Interesting. Thanks Wesj.
