Hi Mike,

Could you help with this bug? 

Thank you.

Comment 3

[Mike Lien[:mlien]]

Hi Alissa, please also check if v2.2 has this issue or not.
If v2.2 also has this problem, you can set blocking-b2g: v2.2? directly

Comment 4

[Alissa（leave from Mozilla）]

Hi,mike
This issue not exist on v2.2

Comment 5

[Mike Lien[:mlien]]

this is v2.1 specific, set blocking-b2g: v2.1?

Comment 6

[bhavana bajaj [:bajaj]]

QA can you please help  reproduce this on 2.0 ? Want to confirm if this is a real regression. Also, can you please stick in the build id for 2.2 that you tested on ?

[Parul Mathur [:pragmatic] - out of office - please ni? [:bajaj] instead]

:daleharvey, could you please take a look at this issue?

Comment 9

[Dale Harvey (:daleharvey)]

I would need some guidance from media to figure out how to fix this, if someone from media could take a look that would be really helpful, thanks

Comment 10

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

This bug probably needs attention from someone on the FxOS media team; ni? slee.

Someone probably needs to step through ChannelMediaResource and/or the MediaCache/ChannelMediaStream code and follow through what happens when the connection drops.

In theory, we should be able to reproduce this same issue on desktop by just disabling your WiFi connection in the middle of streaming a video, or pulling out the ethernet cable.

Attachment: cannot connect to youtube

I tried 2.1 and found that only Youtube has problem. Here is the log. My flow is 
1. connect to youtube
2. disable wifi then enable wifi
3. refresh the page
3.1 youtube cannot connect again and I got some errors from logcat
3.2 connect to other sites and there is no problem
4. restart browser app and connect to youtube. It works fine.

Comment 12

[bhavana bajaj [:bajaj]]

Given this does not happen in 2.2, is there a simple lowrisk workaround or uplift we can do to avoid shipping with this in 2.1 ? dale, would you know here or who is it that I can NI to help investigate this ?

Comment 13

[bhavana bajaj [:bajaj]]

Alissa, can  you confirm there is no way to recover via reload or restarting the app(which is worse) etc? Can we also try this issue on desktop to see if we can reproduce this there?

Dale, Could this be a youtube issue?

Comment 14

[Kevin Grandon :kgrandon]

Since this is not impacting v2.2, is it possible to ask for a reverse regression range to see what fixed this? Once we know that we should be able to determine the risk of an uplift.

Note: we'll need a reverse range here, looking for the commit which *fixed* this.

It should be noted that even on builds that are "working" the user cannot restart playback and must refresh the page instead.  I'm finding the window for at what point refreshing the window was fixed, but the other issue still occurs and seems far more user unfriendly by being the cause of wanting to refresh in the first place.

Somehow flipped those flags opposite of how I intended and removed the wrong keyword...

1.After network connected agian,we cannot reload current video.so it is same on 2.1,2.2,mac.
2.If we relaunch browser after step6 on 2.1,we can play video agian.
3.We do same step(1-6) on mac,after refresh page,we can get normal page agian,so it is same result on2.2 and mac,but it failed on 2.1.

Comment 18

[Kevin Grandon :kgrandon]

Based on comment 11, this is possibly an evangelism bug? Would need someone to dig into the logcat errors as mentioned in that comment. Unfortunately I'm not sure if I'll have time to do this soon.

Bug 880997 might have fixed the refresh issue.

Boris, can you look at this bug please? It looks like this was fixed by the work done on bug 880997

Comment 21

[Boris Zbarsky [:bzbarsky]]

I'm not sure what you want to me to look at, exactly.  The fix for bug 880997 _could_ have changed behavior of some sites that were using the IDL attribute, I guess, depending on what they're doing with it...

Comment 22

[bhavana bajaj [:bajaj]]

Given this isn't a regression in 2.1 and is also fixed in 2.2 I am clearing the nom..

Clearing needinfo and closing as its fixed
