751358 - HTML5 Video is laggy, flashes the whole screen, won't show control buttons, and other issues

Status: RESOLVED FIXED

(Firefox for Android Graveyard :: Plugins, defect)

Description

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0
Build ID: 2012042100

Steps to reproduce:

Played youtube video in Firefox Nightly: http://www.youtube.com/watch?v=g8evyE9TuYk (went to that actual URL and played the on-page HTML5 video.

Using:
Nexus S 4G
Wifi connection
ICS 4.0.4 (google's unrooted stock)
Firefox Nightly



Actual results:

1. When I first pressed on the video nothing appeared to happen, the page did not change.

2. After about 12 seconds, the page started flickering with the entire page having the black and white image that was in the video

3. The video appeared black for a bit, then started showing a laggy video with regular audio

4. None of the interaction buttons would show up (i.e. play/pause, fullscreen, volume) so there was no way to make the video go full screen (and no amount of pressing the video would show these buttons)

5. At one point, the bottom half of the video was in black and white for a few frames (this is incorrect as checked on a desktop)

6. Playing the video does not stop the Android device's screen-saver timeout from engaging. It should keep the screen on


Expected results:

The video should have played/loaded immediately upon pressing and should have showed the control buttons when pressed. There should have been no flickering of the page.

Issue 2 occurs for me when tapping where the video is to zoom the video to screen size (tested with current Aurora nightly). It flickers for a few seconds then the flickering stops.

Issue 6 is covered in Bug 739542

Also see Bug 749107 which was fixed yesterday. Maybe that fixed Issue 2 for you?

It does appear to fix the flickering.

Also, now when I click the video, a set of controls pops up, but:

1. There's no full-screen button

2. The controls do not react to any touch (so the play/pause button doesn't work, the volume button doesn't work and the scroller doesn't work)

Do you still see this on Nightly?

Here's what happens now:

1. I tap to activate the plugin and it starts loading correectly

2. When I press the fullscreen button in the lower right, it rotates the screen, stops playing and now nothing's clickable (the plugin no longer works)

- after step #2 above, I can still move around the page and zoom in/out but the enitre page and plugin bot act like just a dead image - links (and the plugin both) are no longer clickable and the plugin doesn't play

- even worse, I can't even reload the page and it eventually forces me to quit the app

If I instead click the plugin (after I restarted nightly) but never click it again or interact with it, then it does play and does show the buttons (and they never disappear during playing the video)

Clicking any of the buttons (pause, full screen) all cause the browser to freeze the plugin and make the entire browser unusable - and I have to force quit it.

This is with Flash video and is a known issue with full-screen capabilities running under ICS (Android 4.0.4). Please see bug 759747.

I assume this is about Flash? What about HTML5 video's as reported, such as the WebM and Ogg/Theora demos at http://www.quirksmode.org/html5/tests/video.html

You're right, I didn't realize it was switched over ot using Flash. So I joined the HTML5 on youtube and got the following results:

1. The video starts playing when I click it 

2. There is no fullscreen button/icon 

3. The video controls show up at the top of the video (not the bottom like they should) and only have pause, scroller and volume icon (but it's really a mute button)

4. I cannot go full screen but by holding down on the video a context-menu pops up and gives me the option to "pop out" which lets me view it as taking up a full DocumentHeight/DocumentWidth but with the addressbar still showing

5. The pause button/scroller/mute buttons work, however, after you've paused the video, a thin "tooltip"  window pops up over the top hald of the controls  and makes them unclickable

6. There's no way to change the quality of the video feed

7. Playing the video does not stop screen timeout (so the screen goes blank) but the audio keeps playing

There are issues with <video> playback will find the bugs you mentioned or break the issues out to individual bugs. Fixing the scrubber is bug 732052.

But not all of these thigns are fixed.

HTML 5 video does run better but you still cannot choose fullscreen, you cannot change the volume, there's no way to change the quality of the video, etc (you can check this by viewing embedded youtube videos).
