How to set and get user_data for GstBuffer?

[Hunter]

Hello Wim,

    It works.

     Set:
     GstMiniObject* miniObject = reinterpret_cast<GstMiniObject*>(buffer);
    gst_mini_object_set_qdata(miniObject,
g_quark_from_static_string(webkitGstMapInfoQuarkString), mapInfo, 0);

     Get:
     GstMapInfo* mapInfo =
static_cast<GstMapInfo*>(gst_mini_object_get_qdata(miniObject,
g_quark_from_static_string(webkitGstMapInfoQuarkString)));


        Thanks for your rapid replay.
