Hello,
with buildroot Buildroot 2014.02-rc3-00017-g29e5833 and the attached .config file I'm able to run Qt5 + webkit application on the RPi. Still I cannot execute any audio file using Qt5 Multimedia.

I get a warning like this:

defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"

Anyway I can play any file using aplay, or other players. Perhaps I miss some qt-related stuff... did someone run into the same problem?

Thanks!
Marco

#1 lore raw

Hello,
about the problem described below, someone in a Qt forum tells me:

"You need to install GStreamer dev libraries, with the relevant GStreamer plugins for decoding MP3 data."

I found the mp3 plugin in gst-plugins-good (id3demux) but I can't find the -dev libraries of GStreamer 0.1. I searched with F8 in menu nconfig.

Thanks!
Marco
