1088808 - [Camera] Camera app performance deteriorates when taking pictures, leading to app closure.

Status: VERIFIED FIXED

(Firefox OS Graveyard :: Gaia::Camera, defect)

Description

[Martin Shuman [:Marty]]

Attachment: Camera-log.txt

Description:
On a fresh boot of the DUT, the camera app performance will deteriorate with each picture taken.  After about 10-12 pictures, the camera app will close out in what appears to be an LMK or possibly OOM crash.

Additionally, if the camera app is relaunched after this happens, the performance will be significantly worse, and the camera will close out after 3-4 pictures.
   
Repro Steps:
1) Update a Flame device to BuildID: 20141024040202
2) Open the Camera app
3) Attempt to take 15 snapshots
4) Note the performance as you take snapshots.
  
Actual:
Camera app performance deteriorates with use, resulting in app closure.
  
Expected: 
Camera performance remains consistent when using the Camera app, and does not result in app closure.

Adding a video to demonstrate the issue.

Nominating for block in 2.2. 
Bad UX, application will eventually close and return user to home while performing expected functionality.

I can't even get it to show the preview after relaunching, once the initial OOM death occurs. This seems to be in spite of the fact that the free memory levels are similar before and after.

Gaia is the same so it's a Gecko issue.

Reason for blocking: Camera's performance degrades and eventually camera app closes down in about 10 continuous shots that are not too close apart from each other. Regression.

Graphics change in bug 1077301 appears to have introduced the problem.
