Do we need to update or enable anything specific to gstreamer?

    Hi Ikshwaku,
    This is a known limitation with Vision-sdk 3.04 release since vDRM replaces omapdrm for vision-sdk usecases.
    From the log MmRpc_create: Error: open failed, name=/dev/rpmsg-dce
    it looks like even ipumm is also not loaded first of all.

    TI is working on this. Officially gstreamer support will be available in Vision-SDK 3.05 release.
    There are some patches required for gst ducati and gstvpe to have the omapdrm support.
    Will get back to you on this.
