When a <video controls> element is playing a stream with no video track, it can be hard to see where the element is so you can mouse over it to show the controls. In that case, we may as well always show the controls. Maybe the controls binding can check the videoWidth/videoHeight and always show the controls if they're 0,0?

bkap just noted that this happens on Wikipedia, when clicking a link for an audio file... 1) http://en.wikipedia.org/wiki/Hertfordshire 2) Click "listen" (top of intro paragraph) 3) http://upload.wikimedia.org/wikipedia/en/e/ea/UK-Herts.ogg We just create a nsVideoDocument for this, and there's probably no way to determine ahead of time that it should really be an <audio>. This should be easy to fix in the controls.

Comment on attachment 365793 [details] [diff] [review] Patch v.1 a191=beltzner It'd be good to get that test URL written into a Litmus case and in-litmus? added here, I think.

Pushed http://hg.mozilla.org/mozilla-central/rev/92a6bdc7da98

Pushed to 191: http://hg.mozilla.org/releases/mozilla-1.9.1/rev/58b1b2848b74

Steps for Litmus testing: 1) Directly load a audio-only OGG. Wikipedia has lots. For example: http://upload.wikimedia.org/wikipedia/commons/7/74/Schubert-D.935-2.ogg 2) Media should begin playing 3) Controls should be visible without needing to move the mouse over the upper-left area of the page. Moving the mouse in and out of this area shouldn't do anything (controls should stay visible). In a current build *without* this patch, the controls are only shown when the mouse is over the media element. Note that on really slow connections you might notice a slight initial delay before the controls are faded in and playback starts.

Thanks Justin for the testcase. Added Fx3.1 litmus test: https://litmus.mozilla.org/show_test.cgi?id=7603
