843365 - Requesting gUM access, releasing it a few times on gum test page - video eventually fails to show anything

Status: RESOLVED WORKSFORME

(Core :: WebRTC: Audio/Video, defect)

Description

[Jason Smith [:jsmith]]

Device: Galaxy Nexus, Galaxy S3
OS: Android 4.1

Steps:

1. Go to http://mozilla.github.com/webrtc-landing/gum_test.html
2. Select video
3. Hit stop
4. Repeat step #2 and step #3 a few times

Expected:

When video is selected, we should render the camera stream in the video element.

Actual:

After 3 - 5 times, I'll eventually see no video render at all.

Attachment: Debug log

Debug log from a debug build with:
 adb shell am start -a android.activity.MAIN -n org.mozilla.fennec/.App --es env0 NSPR_LOG_MODULES=MediaManager:5,GetUserMedia:5 

The log contains a few successful clicks on the "Audio & Video" link of the gum test page, and the first failure, I cut the log just when it failed for the first time.

The beginning is the same as attachment 716716 [details] but I also included another few failures.

Attachment: Debug log 3

adb shell am start -a android.activity.MAIN -n org.mozilla.fennec/.App --es env0 NSPR_LOG_MODULES=mediamanger:5,getusermedia:6,mediastreamgraph:5

Includes 2 failures.
gzipped as the log is much larger.

Does this problem still reproduce?

> Does this problem still reproduce?

I believe the last time I checked this recently (maybe a week ago?) I was still able to reproduce this very easily.

Are you able to reproduce this?

Comment 8

[Gian-Carlo Pascutto [:gcp]]

With the fix for bug 873812 on my tree I'm not able to reproduce this at all.

Comment 9

[Jason Smith [:jsmith]]

Okay, I'll dupe it to bug 873812 then since the root cause is being fixed there.

Comment 10

[Gian-Carlo Pascutto [:gcp]]

I wouldn't say that. It's just that without that fix on the current tree WebRTC is significantly broken. It may or may not fix this issue. I'd love for you to verify/try as soon as that other bug lands.

Comment 11

[Jason Smith [:jsmith]]

Okay. I'll wait that patch to land to start testing this again.

Comment 12

[Jason Smith [:jsmith]]

QA wanted for a retest to see if the associated bug mentioned above fixed this issue.

Comment 13

[Aaron Train [:aaronmt]]

This is much better than it was previous to the landing of the patch in the aforementioned bug. Testing comment #0 on Nightly (06/02), on my HTC One (Android 4.1) and Galaxy S4 (Android 4.2), I am seeing a clean start and stop and permission request each time now. Resolving this as WORKSFORME.
