    Hi,
    currently i am using qt5.3 cross-compiled on rpi wheezy.
    I would like to upgrade to jezzy and then to qt5.5.1 or qt5.6.

    There is a new guide, which claims to enable hw accelerated opengl: http://wiki.qt.io/RaspberryPi2EGLFS

    1. Does this include playing hw accelerated videos through qtmultimedia?
    2. If yes, how does that work? I thought it requires gstreamer 1.x which is not included in the "configure" command
    3. There were a few posts, that reported on qt5.5.0, that gstreamer1.0 doesn't work with the egfls plugin. Those posts are a few month old, though. Has this been fixed, or is it still not possible?

    Thanks a lot for your help,
    Ben

      Hi. I'm using Debian 8 (jessie), by upgrading my Raspberry Pi from Debian 7 and Qt 5.5.1.
      I confirm that Qml and OpenGL ES does not work.
      I'll try Qt 5.1.1 during the weekend with the official Debian Jessie iso.
      If you will be able to run a Qml application in Raspberry please write here.
      I'm very interested because if there isn't a solution I have to downgrade two Qml applications to QtWidgets

        My question was about hw accelerated movies using qtmultimedia.
        I compiled qt 5.3 a while ago for rpi 1 and that works like a charm.
        I am using qml and that's run hw accelerated on the pi.

          Ah, ok.
          After following the guide still I can't use qml, I obtain the generic error "not find platform plugin eglfs" but it is list after.
          Can you explain how to start a qml application? Are you using xorg as container or simply something link ./App -platform eglfs??

            Hm, can't remember how i did it at the beginning.
            Right now, i am compyling and deploying my apps fro qtcreator on my host linux pc. After that i can simply run the apps on the pi by ./myApp -> without the platform option

                @ben80 There is now a section about Qt Multimedia on the page. It is not quite reliable for now, unfortunately.

                  To have qtmultimedia (hw decode) use this : http://thebugfreeblog.blogspot.fr/ , it works like a charm !!!
