Playing videos crashes in /android/system/lib/libgui.so

[Albert Astals Cid]

Using the code from
   https://code.launchpad.net/~unity-team/unity8/inline-dash-videos/+merge/280594

One can play videos in unity8 dash directly.

I have recorded 2 short videos (4 or 5 seconds) using the camera application, if i play them, at some point the dash will crash (on arale)

Backtrace for current thread is not very useful
[Switching to Thread 0xa78b4410 (LWP 4163)]
0xb24a272e in ?? ()

Other than to show the crash happens inside /android/system/lib/libgui.so
$ grep libgui.so /proc/`pidof unity8-dash`/maps

@albert why did you task this to qt?

[Albert Astals Cid (aacid)]

@Pat because we're using the Qt Multimedia components to play it from the unity8 code, so that is the immediate place where to start investigating.

Given the library it crashes it is probable the bug is in lower layers (media-hub, something else) but it's may also be that the Qt Multimedia components are using those lower layers wrong.

So after I could not find anything wrong in the unity8 side of the code I decided to pass the bug to the layer unity8 uses, if someone that knows Qt Multimedia investigates it and finds nothing wrong I guess it should be passed down again.

Would you have prefered I had task it somewhere else?

@Albert: any ideas if this is still occurring for you? I'm looking into this for this current sprint and want to make sure it's still reproducible.

[Albert Astals Cid (aacid)]

Actually no, i can not reproduce it anymore, no idea if it was fixed somewhere else or what but i can't see if happening.
