Part Number: BEAGLEBOARD-X15

Hello sir,

I am using Beagleboard X15 and i am downloaded Debian 9.5 2018-10-07 4GB SD LXQT image loaded through SD card.

Through System command line installed Gstreamer1.0-0 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.

    Hi Ramachandra,

    I replied to your other thread that was a day or two newer.  Are you still trying to get this working on Debian, or have you moved to the Processor SDK (Yocto) filesystem?

    You will need to get support with this from the BeagleBoard.org google group.

    Regards,
    Mike
