[Android-development] Full-featured video player

[Dominik]

Hi,

you're right. I've tried it in another device and TS file works, now. On
the other hand MP4 file doesn't but it's a platform problem I suppose. I
have to study harder how this things work.

I would like to ask for more questions about media player in Qt and android.

1) I need to be able to switch audio and subtitle tracks. Is it possible
somehow or will be? Now, all metadata attributes returns undefined. How
much this depends on android API?

2) Both examples, qmlvideo and qmlvideofx, are perfectly working but one
thing is not. When I press "back" button in qmlvideo or "reset" in
qmlvideofx, when scene should be redrawed, the application crashes with
Fatal signal 11 (SIGSEGV) http://pastebin.com/VuRp4XP1 . Is it caused
because of qtmultimedia is still in development or did I something wrong?

Thank you very much.

Dominik
