[maemo-users] gcompris port to Maemo --- help needed with gstreamer

[From: Terje Bergström]

Hi,

I have tried to port gcompris (educational games suite for kids) to maemo. The 
basic functionality kind of works, and I have packaged the software into 
debian packages. It requires libgnomecanvas from 
http://maemo.org.br/platform/apt. Just add

deb http://www.maemo.org.br/platform/apt mistral user
deb-src http://www.maemo.org.br/platform/apt mistral user

to your sources.list and install libgnomecanvas2, libgnomecanvas2-common and 
libgnomecanvas2-dev. The server doesn't seem to be responding now, but 
hopefully soon it will.

The gcompris code itself is in http://garage.maemo.org/projects/gcompris. I 
haven't uploaded binary packages yet, so you'll need to build it from svn.

One major problem is still audio. Most of gcompris' audio is in ogg vorbis 
format. This is a problem, as N800 does not support ogg vorbis, so I 
converted all audio to mp3's. As gcompris uses SDL to play audio, mp3's need 
something else to be played. 

I tried to make gcompris use gstreamer for playback, but it seems that I just 
can't get the pipeline right. If anyone could give me a hand and look at the 
code in svn:

https://garage.maemo.org/plugins/scmsvn/viewcvs.php/trunk/gcompris/src/gcompris/gstplayer.c?root=gcompris&view=markup

The idea is that sdlplayer_fx() and sdlplayer_music() start playing sound and 
don't return before sound has been completed. Currently no sound starts 
playing and the function never returns.

Thanks for any help!

Best regards,
Terje
