    Hi sir,

    I am using beagleboard-x15 SD card images from below website i downloaded ( Debian 9.5 2018-10-07 4GB SD LXQT image)

    Wbsite:

     after that i am installed gstreamer using below commands:

    #sudo apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio

    # sudo apt-get update.

    #reboot

    after system startup downloaded some images and used whatever you suggested commands only.

    Hello,

    We do not support Debian and TI only supports our PSDK Linux.
