Memory Leak in QCAR Object

March 3, 2014 - 7:30am #1

I am building an app with Vuforia that is similar to the Video Playback sample app from Vuforia.

I noticed that there is one leaking object when you start and stop playing video in QCAR::Obb2D.

I have seem previous forum posts where other developers seem to have the same problem here and here.

Has anyone been able to resolve this memory leak issue?

Hi Nalin,

We were able to reproduce the issue with the sample Video Playback applications when we simply increased the number of targets for the application.

I can send you a more detailed response in a bit.

Are you guys aware of this?

No, this sounds very much like an application specific issue that is unlikely to be related to Vuforia.

If you have 10 targets all linked to videos there could be any number of issues related to your own application.

 

If you believe there is a problem, then work hard to fully understand the cause - analyze and profile using Instruments and most importantly see if you can reproduce with one of the existing samples.

 

Hope this makes sense.

Hi Nalin,

So we are getting a Memory Leak warning that crashed the app when we try to load more then 10 targets (that are linked to videos) on any device below an iPhone 5. Are you guys aware of this?

Hi,

As you have mentioned this has come up before, and the dev team are fully aware of this.

However this is nothing to worry about, so do not let it stop you from building Apps.
