After some problems with gstreamer autoplug on maemo environment because the audio sink and decoder in the same element, I create this element "playbinmaemo", this is very simple to use like gstreamer playbin but this is more simple and small, you can play any audio and video files supoorted by device.
For now you can play files using gst-launch like this:
gst-launch-0.10 playbinmaemo uri=file:///home/user/MyDocs/.videos/Nokia_N800.avi
gst-launch-0.10 playbinmaemo uri=file:///home/user/MyDocs/.sounds/Road_To_Ruin.mp3
Ogg Vorbis is supported to, but you need install decode element from: https://garage.maemo.org/projects/mogg/
The package can be found on gmyth project page:
