4. QMediaPlayer on Ubuntu 16.04 GStreamer error

QMediaPlayer on Ubuntu 16.04 GStreamer error


  • Hello,

    I've been trying to create a videoplayer for my app, but I'm having trouble with the QMediaPlayer.

    I set the QT_DEBUG_PLUGINS environment variable to 1, and the log I got after calling my application is this one:

Error: "Your GStreamer installation is missing a plug-in."

    The error is clear, a problem with GStreamer but I tried several times to install/uninstall packages and couldn't make it work.

    For what I've seen, in theory I should have GStreamer0.10 installed with all its plugins, but I've installed all the dev and plugin packages and I still get the same error (although before I had another one which I was able to overcome!).

    I can't find a solution for it, maybe someone here can help me (older posts didn't work either :/ ).

    The ubuntu version is 16.04 and running in a x64 machine. My QT version is the 5.7.

    Thanks!

    Hi and welcome to devnet,

    If you call ldd on the GStreamer plugin, what do you get ?

    Is it this what you wanted me to do? I don't know how to call it on the GStreamer plugin if it's not that.

    Is: linux-vdso.so.1 the problem?

    Which gstreamer plugin package do you have installed ?

    I ended up installing most of the packages that something to do with GStreamer plugins x). You can take a look at the image to see the GStreamer packages that I ended up installing. The 1.0 packages where already installed I think.

  • Solved, gstreamer-0.10-ffmpeg was missing.

    sudo add-apt-repository ppa:mc3man/gstffmpeg-keep
sudo apt-get update
sudo apt-get install gstreamer0.10-ffmpeg

    UPDATE:

    Not really solved, using this plugin breaks GStreamer:
