User is watching a video in the browser. The user taps the 'fullscreen' button, and immediately rotates the device into landscape orientation. After pressing 'Allow' in the fullscreen prompt, the video player appears in fullscreen, but only a blank grey background is visible. No audio is playing either, but the timer continues to increment and the seek bar can be adjusted.

Repro Steps:
1) Updated Buri to BuildID: 20140127004002
2) Launch Browser.
3) Navigate to http:/bit.ly/1bsSLUz.
4) Type something into the search bar and wait for a video load onto the page. (I searched for 'fail', and watched the first available video)
5) Click the 'play' button to load the video.
6) When the video begins to play, tap the fullscreen button and immediately rotate the device into landscape orientation.
7) Press 'Allow' when prompted to allow fullscreen.

Audio and Video are not displayed, but timer and seek bar continue to function.

Video plays properly in landscape fullscreen.

I saw this problem as well. We can't end up in a situation where a video fails to playback in fullscreen.

blocking-b2g: --- → 1.3?
We discussed this later in triage when product joined the call - the proposal going forward is to throw an error when video is detected given the fact that quality of video with RTSP is poor. This would be a blocker for shipping video support for RTSP, so moving this to 1.4?

It blocks 1.4 feature.
blocking-b2g: 1.4? → 1.4+
No longer going to block - RTSP video needs to be preffed off in 1.4 per a drivers decision to cut scope to only DSDS & QC required features.
