940891 - MP4 playback yields greyed out content

Status: RESOLVED DUPLICATE of bug 934412

(Core :: Layout, defect)

Description

Attachment: unnamed.png

On my Samsung Galaxy Note 2, mp4 facebook videos broke roughly 2 weeks ago. Videos (which used to show and play properly on top of a gray background in a new tab) now only shows the gray background with no video being displayed. The audio plays fine.

The playback controls are also not visible, only a lighter gray rectangle shows up for a couple of seconds.

See attached screenshot

When you attempt to play the video, can you capture and attach to this bug a logcat from the device?

Comment 3

[Aaron Train [:aaronmt]]

Not really convinced it's the same bug.

Comment 4

[Mathieu Pellerin]

Aaron is right, it's _not_ a duplicate of bug 825158. That bug is about video embeds not playing well within Facebook's news feed. That other bug a problem that's been affecting Firefox Android for as long as I can remember.

This bug, however, is a new regression that's been affection Nightly on my Samsung Galaxy Note 2 for less than a month. 

* Steps to reproduce (on a Note 2):
1. Open a Facebook video page (for e.g. https://www.facebook.com/licadho/posts/714685888560521) on Firefox Nightly Android
2. Push the Play button to start video playback

* What is happening:
A new gray-background tab opens, but the video control and frames are not showing up while the audio can be heard.

* What should happen:
- Since Firefox Android doesn't support playing video within Facebook pages, the .mp4 opens in a new gray-background video tab, and its playback starts.

Aaron, I'm not seeing any video-related entry in my system's logcat.

Comment 6

[cajbir (:cajbir)]

Does MP4 video play on any other site? Do you see anything in logcat referencing OMX?

Comment 7

[Mathieu Pellerin]

Chris Double, no, also broken. If I open this mp4 (http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4), I get the same neutral gray background (which firefox uses to display images / videos / audios) with missing video controls and no frames.

[Mathieu Pellerin]

This should have been mentioned when I filed the bug: my Note 2 model number is GT-N7100 running android 4.1.2.

Comment 9

[Aaron Train [:aaronmt]]

Thanks for noting. I have a Samsung Galaxy Note II (Android 4.2) as well and am able to reproduce this. Narrowing down a regression-range on mozilla-central, I have the window as:

Last good nightly: 2013-11-07
First bad nightly: 2013-11-08

http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2013-11-07&enddate=2013-11-08

On mozilla-inbound

http://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=f396166fb1a5&tochange=5251ff6456d9

This is reproducible on my Nexus 4 as well. This needs a bi-sect from that range as nothing really stands out.

[Aaron Train [:aaronmt]]

Kevin, can you reproduce on a Nexus 4 or a Note II with that test-case URL? Can you bi-sect that inbound range?

[Mark Finkle (:mfinkle) (use needinfo?)]

We could also use b2g-inbound builds to find the range.

Bug 934860?

Comment 16

[cajbir (:cajbir)]

There are a bunch of these bugs at the moment, evidenced by logcat of:

I/OmxPlugin( 1942): Unknown video color format: 0x7fa30c03
I/OmxPlugin( 1942): Falling back to software decoder

See bug 934412 comment 7 for example. Edwin, is there a canonical bug for these?

Comment 17

[Edwin Flores [inactive from 2016-12-01] [:eflores] [:edwin]]

This is due to a couple of bugs; of those 934412 is likely to be fixed soon.

As a workaround for now, you can set layers.use-deprecated-textures = true.
