RTSP stream - Gstreamer error

  • Hello
    I am trying to run RTSP stream on DM900 from Hikvision IP camera.
    I added it to userbouquet as

    #SERVICE 4097:0:1:0:0:0:0:0:0:0:rtsp%3a//admin%3apw@

    (URL is working correctly in PC using VLC)
    When I switch that channel I am getting this error

    Do you have any idea what is causing it ? I was thinking about downloading additional Gstreamer plugin but there are so many of them and I have no idea which one could solve that.
    Thanks for any suggestion.
