QMultiMedia not playing properly / not playing at all
I`m facing some difficulties with the multimedia library. I plan to use the QGraphicsVideoItem in a project however, i needed to do some performance tests first. The first step was too see if the example projects functioned properly however i haven't managed to get them to work properly.
the videowidget example project produces the following error:
When attempting to play an .mp4 movie
- Error: "Gstreamer encountered a general stream error"
When attempting to play an .avi movie
- Error: "Internal data stream error."
The screen stays black.
When attempting the same thing at the videographicsitem example project the result is different:
When loading the movie the following error appears:
- Failed to start video surface
However, the movie does start and functions properly.
I`m guessing it has something to do with the gsteamer libraries but i'm not sure. Does anyone know what/where to look for ?
Some additional information:
- When i execute gst-launch playbin uri=file:///some movie it plays the movie
- Running OpenSUSE 12.3 in a virtual machine (host windows 7)

Make sure you have all GStreamer 0.10 plugins installed. That is: gstreamer-plugins-good, gstreamer-plugins-ugly, gstreamer-plugins-bad and gstreamer-plugins-ffmpeg.

and i think you must install ffmepg in OpeenSuse.
I'm experiencing the same error : all my movies (.mpg, .mpeg, .avi, .wmv, etc.) play well with gst-lauch but i get the "internal data error" message. I have installed all necessary gstreamer plugins.
Why "videowidget" example doesn't work ?
I'm using Qt 5.2 with Qt Creator 3.0.
Any solution for this? I'm facing the same issue with the Raspberry pi.

I'm currently facing the exact same problem, and it's quite strange since i can use either totem, gnome-open, gst-launch playbin "myvideo.mp4", but the problem appears when i try to launch it with qt and i get this: "Gstreamer encountered a general stream error" with a .mp4
