QMediaPlayer and GStreamer plug-ins

  • Hello!
    A couple of days ago I started working with QMediaPLayer (from Qt 5.5.1) on Ubuntu 15.10 x64.
    And I cannot resolve a problem related to play audio.
    Here are the errors from the output window:

    GStreamer; Unable to pause - "file:///home/slava/Music/02. Above & Beyond feat. Zoe Johnston - We're All We Need.mp3"
    Error: "Your GStreamer installation is missing a plug-in."
    Warning: "No decoder available for type 'application/x-id3'."

    And dialogs which appear when I open audio: from 2016-01-07 12-44-17.png?dl=0 from 2016-01-07 12-44-36.png?dl=0

    I've looked through many topics, related to GStreamer and plug-ins, and I've executed many commands on the terminal. There is no result, since I'm getting the same output as above.

    Thanks for any help and suggestion!

    Hi and welcome.
    Did you try this?

    sudo apt-get install gstreamer0.10-ffmpeg

  • Hello @Ratzz, thank you for reply.
    I did this before and I've just done it again:

    gstreamer0.10-ffmpeg is already the newest version.
    The following packages were automatically installed and are no longer required:
      brasero-cdrkit libchromaprint0 libde265-0 libfluidsynth1 libgtkglext1
      libilmbase12 libmpg123-0 libopencv-calib3d2.4v5 libopencv-contrib2.4v5
      libopencv-features2d2.4v5 libopencv-flann2.4v5 libopencv-highgui2.4v5
      libopencv-legacy2.4v5 libopencv-ml2.4v5 libopencv-objdetect2.4v5
      libopencv-video2.4v5 libopenexr22 libsrtp0
    Use 'apt-get autoremove' to remove them.
    0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

    Maybe I have a conflict in the system with other installed libraries or softwares. Puzzle...

    I'm not sure but IIRC, 5.5.1 might be using GStreamer 1.0.

  • Hello, @SGaist! Thank you for your assistance.

    I installed GStreamer1.0 using

    sudo add-apt-repository ppa:gstreamer-developers/ppa
    sudo apt-get update
    sudo apt-get install gstreamer1.0*

    But I'm getting the same error.

    Try running gst-inspect id3demux

  • Hi, @SGaist!
    Now things go well.
    I've just used a brute force method. And it helped me.
    I think a bad plugin was missed in the system. But I'm not sure. Here is a list of the latest commands:

    106  apt-get install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev
    107  sudo apt-get install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev
    108  sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
    109  sudo apt-get install libgstreamer1.2-dev libgstreamer-plugins-base1.2-dev
    110  sudo apt-get install gstreamer0.10-plugins-bad
    111  sudo apt-get install gstreamer1.0-plugins-bad
    112  sudo apt-get install ubuntu-restricted-addons
    113  sudo apt-get install gstreamer0.10-plugins-bad-multiverse
    114  sudo apt-get install gstreamer1.0-plugins-bad-multiverse

    As for get-inspect command:

    No command 'get-inspect' found, did you mean:
    Command 'gst-inspect' from package 'gstreamer-tools' (main)
    get-inspect: command not found

    Thanks for all :)
