Actual results: 1. On first playback, seek bar goes all to the right. 2. Subsequent playback skips the first 5 seconds of content. Expected results: No skipping of content. regression range for problem 2: Last good revision: 12ea03a70243 (2013-12-11) First bad revision: 1ad9af3a2ab8 (2013-12-12) Pushlog: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=12ea03a70243&tochange=1ad9af3a2ab8
The first Nightly that observes issue 1 (seek bar problem) is 2012-12-03 build (rev 8648aa476eef) which predates VP9 implementation. vp9cake.webm plays with audio only on this build and the seek bar goes all to the right. Prior to this Nightly the file cannot be played at all. Something forgot to mention in original post: In current Nightly, if I save vp9cake.webm locally and play it in Nightly again, problem 1 is gone but problem 2 persists.

Comment on attachment 8633454 [details] [diff] [review] Bug-1034081-Never-seek-before-startTime.patch Approval Request Comment [Feature/regressing bug #]: Bug 945863 [User impact if declined]: Some videos fail to start [Describe test coverage new/current, TreeHerder]: Landed on nightly last week, passing playback mochitests. [Risks and why]: I believe risk is acceptable. This codepath doesn't get a huge amount of use, but it's an annoying bug for people who are using WebM with HTML5 video. Rest of the code hasn't changed lately, so chance of side-effect is small and backout in case of regression would be easy. [String/UUID change made/needed]: None.
