[Qt-interest] Problems with Mac audio

[Darryl Hunter]

Hi all,

 

I haven't been using a Mac for that long, but my customer wants an
application to run on it.  So I've got a MacBook and am working things out.

 

Part of my project (which I started over a year ago now) is utilising the
Phonon framework.  I have based parts of my implementation on the
qmediaplayer example, and have been able to reproduce a bug in that.

 

I have a divx movie.  If I play it in the DivXPlayer on the MacBook, it
plays fine (well, video is jittery, but audio works OK).

 

If I open the divx movie using the qmediaplayer example, the video plays
fine (not jittery), but I get no audio.

 

If I open an avi file in the qmediaplayer example, I do get audio.

 

So what I've confirmed is:

-          The Mac system knows how to decode the audio from the DivX

-          The QMediaPlayer example knows how to extract and play audio

 

So it's as though I need to somehow link the QMediaPlayer with something
else so it knows how to access the sound in the DivX file.  From what I
understand with Windows, once you install the Codec it is available for all
applications.  Do I need to establish this link on the Mac separately?

 

Unfortunately, because of the content in the DivX file, I can't provide
that.

 

Any ideas?

 

Thanks.

 

Darryl
