Has anyone had any luck with more complicated N770 gstreamer apps? I'm
playing with a custom streaming media app and it's unstable to say the

Hi,
Does someone know how to playback mp3 or wav or pcm file
using gst-launch ?
I have alsasink and osssink problems in both SDK_PC and

Is there a need for new "mad" plugin and where can I get
it ? I found only one for 0.8 and Maemo 2.0 uses gst 0.10.

Hi Ronny,
Afaik (and I haven't looked at this myself) the way the DSP plugins in
Maemo work is that they are all sinks themselves. So instead of decoding
a mp3 using an mp3 plugin then outputting the sound to for instance an
alsasink, you just send the mp3 file to the mp3sink and it will also
