this is the point: the stream seems not rtp payloded or at least gstreamer 
doesn't recognize it as rtp

gstbasertpdepayload.c(360): gst_base_rtp_depayload_chain (): 
/GstPipeline:pipeline0/GstRtpMP4VDepay:rtpmp4vdepay0:
Not RTP format was negotiated

but the stream would be rtp according to verint,

thanks
