    I have been working on an app that is using both webkit & gstreamer 1.0.

    GStreamer seemed unusable in this particluar app.
    After hours of searching, i figured out that QtWebkit was using GStreamer 0.10 and that it was purely impossible to use GStreamer 1.0 in the same app.

    GStreamer 0.10 has been abandonned since 2013. I was hoping to see Gstreamer 1.0 coming into qt 5.4 both for QtWebKit and QtMultimedia, but it seems at least that in the 5.4RC it is still using gstreamer 0.1.

    I have seen a large number of posts & mailing list mentionning that the port was in progress.

    Is it possible to have some feedback about this please ?

    This is so frustrating not to be able to use a not so recent gstreamer version ....

      Hi,

      Looks like this "mail answer":http://lists.qt-project.org/pipermail/development/2014-November/019166.html is what you are looking for

        Thanks SGaist glad to see it's coming :)

        Not sure what's the best place to ask between forums / mailing lists, but will it be possible to get some information about the way to get it built from dev branch ?

        I mean i know how to build qt from dev branch, but i have read of eventual configure flags to use so that it uses GStreamer 1.0, would be nice to give it a shot and be able to move on :)

          digging into QtMultemidia repo on the dev branch, i found this commit :

          https://qt.gitorious.org/qt/qtmultimedia/commit/108dda7a90bd0f0337358b0db47ae55acd16dea6

          it's not 100% clear to me how to pass the GST_VERSION=1.0 to qmake.

          I tried both :

          GST_VERSION=1.0 /usr/local/Qt-5.5.0/bin/qmake

          and

          /usr/local/Qt-5.5.0/bin/qmake CONFIG+= "GST_VERSION=1.0"

          but the config doesnt seem to find gstreamer

          if i look at config.log i can see :

          cd /home/pi/qt5-dev/qtmultimedia/config.tests/gstreamer && /usr/local/Qt-5.5.0/bin/qmake -spec /usr/local/Qt-5.5.0/mkspecs/linux-g++ "CONFIG -= qt debug_and_release app_bundle lib_bundle" /home/pi/qt5-dev/qtmultimedia/config.tests/gstreamer
          Project ERROR: gstreamer-0.10 development package not found

          So it's more likely still looking for 0.10 version ...

          Did i do something wrong with passing the GST_VERSION parameter ?
