Hi, Alissa,

May I have I request?
Please provide the correct information.
Bug 1120875 doesn't have comment 41, right?

Comment 3

[William Hsu [:whsu]]

I think this is edge case. I cannot associate this case with any general user scenario since I think user is not likely to play RTSP streaming with no internet connection, and then launch video in 10 seconds.

Also, I think this message only can be easily triggered on low-end device because system resource is easy to lock.
So, we need to tell user that the resource is occupied when it happens.

But, I think we can double check behavior with feature owner.

Hi, Ethan,

May I have your help?

We saw a system notification when user plays RTSP streaming with no internet access, and then play a video.
As demo video. (RTSP.3gp)
Do you think it is expected behavior?

If you aren't the right person to ask this question, please help me forward it.
Many thanks.

For this ,why we failed  video playing with no internet is just to simulate the situation when network is lost. Maybe there are other way to fail RTSP playing, but this way is easy to repro.

After reading the STR description and watching the attached video, I think this is actually the
same problem as bug 1111978.
Although the steps to cause RTSP failure are different, the essential of these two bugs is the same.
Any RTSP failure should not block playing video in other apps.

Perhaps the patch of bug 1111978 does not resolve this problem thoroughly.
I will look into it to find out what's wrong.


Alissa,
I remember you mentioned that this bug happens on 2.1 but not on 2.2.
Is that right?

Hi Lance, could you also help to verify if this issue can be reproduced on v2.1S?
Since this is a branch specific issue, we may only fixed on partner branch.

Hi ettseng,

Since the patch of bug 1111978 on v2.1s causes the fonflict, I can't merge it into v2.1s. Could you please help to attach the patch for v2.1s? Thanks

I don't get it.
The patch of bug 1111978 already landed in v2.1s on 2014/12/31.
https://hg.mozilla.org/releases/mozilla-b2g34_v2_1s/rev/ae2af1ecd237

Why do you want to merge it to v2.1s?

Actually this bug requires another patch to fix (see comment 7).
I was working on other tasks and haven't dig into this bug yet.

Jonathan, please help to take this bug, thanks.

Comment 19

[Jonathan Hao (inactive) [:jhao]]

At first, I cannot reproduce the bug. Then I noticed that in Lance's video, he tap the video many times in video app. So I tried to tap the video for many times very quickly, and I can reproduce the error message, without opening RTSP video beforehand.

Therefore, I think the problem wasn't that RTSP occupied the hardware. The problem was that user tap the video many times. The first tap opened the video, but before the video was open, the second tap is rejected because the first tap makes the hardware occupied.

I think the bug belongs to video app instead of the RTSP component.

Comment 20

[Jonathan Hao (inactive) [:jhao]]

Even though I had to tap more quickly than Lance does in his video, but I guess it depends on the timing, and I doubt that if it can be reproduced if you only tap the video once.

Also, the error message is only visible for a very short moment. The video can be played very soon after that. I don't think it is a blocker.

[Ethan Tseng [:ethan]]

According to comment 19 and comment 20, I think this issue is minor and shouldn't be a blocker.
Steve, could you please confirm that we can remove the blocker flag?

Comment 22

[Steven Yang [:styang]]

agree. clear the plus. thanks.

Comment 23

[Vincent Liu[:vliu]]

Clear the ni? since the Comment 22.

Comment 24

[Jonathan Hao (inactive) [:jhao]]

Unassign myself since I'm not actively working on Firefox OS anymore.

Comment 25

[Ethan Tseng [:ethan]]

RTSP in FxOS is rarely used by users.
Unless there is strong user demand/requirement, I don't think anyone will fix this bug.
