1024517 - [Flame] Video app sometimes fails to index videos.

Status: RESOLVED DUPLICATE of bug 1050667

(Firefox OS Graveyard :: Gaia::UI Tests, defect, P1)

Description

[Robert Chira [:RobertC]]

Video app tests are failing because tapping on the thumbnail does not work.
http://selenium.qa.mtv2.mozilla.com:8080/view/B2G/job/b2g.flame.mozilla-central.ui.non-smoketest/65/HTML_Report/

This issue cannot be reproduced manually. I ran the tests locally and they failed consistently.

NOTE: While the test ran I tried tapping on the video and it still would not load.
This seems to be a bug in the tests.

I can see it constantly scanning for files

Comment 2

[Viorela Ioia [:viorela]]

The test_play_webm_video failed in the latest v1.4 build too, for the same reason. 
I was able to reproduce the failure locally, by running the automated test, intermittently (rarely). 
I was not able to reproduce it manually.

The last one included results from several tests.
Here is a better logcat.

Notable events:

Jsmith, can you advise, do you know who to direct this logcat to?

[Jason Smith [:jsmith]]

Hema - Can someone from your team take a look at the logcat provided & provide feedback on the problem here?

Comment 10

[Hema Koka [:hema]]

Russ can you help here?

Comment 11

[Russ Nicoletti [:russn]]

The error

"E/GeckoConsole( 7646): Content JS ERROR at app://video.gaiamobile.org/gaia_build_defer_index.js:483 in getMetadata/offscreenVideo.onerror: Can't play video /sdcard/tests/VID_0001.3gp [object XrayWrapper [object Event]]"

indicates the video metadata could not be read. This happens when the video is being loaded into an 'offscreen' video element for the purposes of getting the metadata. In this case, the cause of the error is that the video could not be decoded. 

It does seem like the problem of the video app not being able to load the video is due to bug 1024324 because I flashed the latest master build on my flame and the video loads successfully.

Comment 12

[Jason Smith [:jsmith]]

We should check if this reproduces post landing of bug 1024405, as I think that might be the root cause of the problem here.

Clarified offline, but still reproduces post landing of that patch.

Do you have a logcat for the latest failure? Are you still seeing the JS error from comment #6?

I can still replicate this, around 2 in 20.

I've attached a new logcat, although the error message looks the same.

[Russ Nicoletti [:russn]]

It's odd that the error would be intermittent. Anyway, I'm trying to recreate on my box but I'm not able to run gaiatest/apps/videoplayer/regions/fullscreen_video.py. I can run other ui tests but when I run that one in particular it doesn't execute. Input and output below:

Comment 18

[Zac C (:zac)]

Yes that's not a test file, it's a class. The test file is:

gaiatest/tests/functional/videoplayer/test_play_3gp_video.py

you can also add --repeat 10

Comment 19

[Russ Nicoletti [:russn]]

I'm able to reproduce now. However, I'm not able to see additional logging that I've added in my logcat output so I'm not able to narrow down when in the process this is happening. In any event, the intermittent error decoding the video would appear to be a gecko issue. 

Jason, can you ni a gecko dev to have them look into this intermittent decoding error? Thanks.

Comment 20

[Jason Smith [:jsmith]]

I know Chris landed bug 979104, which could be related to this.

Chris - Any thoughts on the root cause here? Could it be caused by bug 979104?

Comment 21

[Chris Pearce [:cpearce (Not reading bugmail)]]

Yes, this could be caused by bug 979104. Please ensure that the build your testing includes the fix from bug 1024405:

Bebe, can you capture a logcat? Does it have the same error message as described in comment #6 and #11?

It sounds suspiciously like the same problem.

Actual:
3. The video app can't find any videos

Comment 35

[Jason Smith [:jsmith]]

Can someone else confirm the reproduction rate above manually?

Comment 37

[Zac C (:zac)]

I don't think the error in comment #34 is the correct one.

I can replicate this intermittently by running the test locally.

In that scenario I get this error message:

E/GeckoConsole(12491): Content JS ERROR at app://video.gaiamobile.org/gaia_build_defer_index.js:528 in getMetadata/offscreenVideo.onerror: Can't play video /sdcard/tests/VID_0001.3gp [object Event]

Comment 38

[Zac C (:zac)]

DJF, based on the above error message on a device after pushing a file to it. It's an intermittent at about 1 in 10.

Can I expand that error message somehow (e.stack or e.message?) or enhance the debugging to find out why this failed?

We are pushing the file which is 132kb with adb so it really shouldn't be any problem here.

If you haven't already found it in the source code, the error is being printed at apps/video/js/metadata.js:184

Note that the variable e is an Event object, not an Error object, so it probably doesn't have a stack trace.  I'm not actually sure what it has. It looks like I was hoping it had a meaningful toString() method since I passed it directly to the console.error() function. You might just need to do a for/in loop over the object to see whether it has any useful properties.  I suspect you won't find much, however.

Does the bug go away if you use a .webm or other video format instead of .3gp? IIRC .3gp uses h.264. And if the decoder for that relies on any kind of hardware acceleration on the host machine, perhaps there is some kind of contention for that or other problem?  If you're not trying to test specifically for .3gp support here, perhaps you could just make the intermittent go away with a different format.

Comment 40

[Zac C (:zac)]

Thanks djf, this bug is not specific to 3gp. We have seen it with other video formats in the past but at the moment I'm focusing on this one. The host is the Flame device so it should have the codec and it should run fine.

We don't see any similar issues for music or gallery apps which gives me some trust in the framework that we're using to push and pull files to the device.

(It may also be related to bug https://bugzilla.mozilla.org/show_bug.cgi?id=1065989)

I'll have to come back to this on Monday, or if you're interested in running the tests yourself the instructions are in comment #4 of bug 1065989.

Comment 41

[Zac C (:zac)]

djf, would you mind debugging this for us? I do think it's worthy of investigation by a Video app dev seeing as the issue is unique to Video app, I feel comfortable excluding the test framework from blame.

Zac: The info in the comment above doesn't seem to tell me anything useful, except maybe the file size. Is that the correct file size? Also, you've said that it is not specific to .3gp. What I'm really wondering is whether it is specfic to video formats that need to use hardware for decoding. I think that an .ogv video would be pure software and that other formats probably use hardware (though I don't really know for sure.) So knowing whether this reproduces with .ogv would probably tell us a lot.

I don't think I can personally help debug this, because it does not look like a Gaia issue. It looks to me like something is going wrong in gecko or gonk. 

Aseking thought this might be a dupe of 1024324, and Sotaro worked on that bug, so maybe he will have some insight for this one...  

Sotaro: could you take a look at the logcat in https://bug1024517.bugzilla.mozilla.org/attachment.cgi?id=8464594 and see if it tells you anything about why the video is failing to load here? Note that this apparently only happens when the video app is being run by Marionette tests. In particular, I'm curious about these messages from the log:

  E WVMExtractor: Failed to open libwvm.so

  V IMediaResourceManagerDeathNotifier: getMediaResourceManagerService

  V GonkConsumerBase: abandon

Recently, Bug 1050667 is created. It seems similar bug. Comment 42 does not provide the information about the problem.

Thanks Sotaro,

I tried our automated test with the Webm file attached to bug 1050667 and I replicated the bug immediately, although that was fortunate, it's still an intermittent issue.

I agree it's similar and I'm going to mark this as a duplicate of that one and observe the results after that patch has landed.

dfj, thanks for your help! I wish I'd had the time to push on this sooner, we might have found it before the partner did.
