[Solved]ofxGstRTP to OpenCV's VideoCapture

I’m enjoying the ofxGStreamer and ofxGstRTP for video streaming.

For casual use, I want to use it with OpenCV only without ofxGStreamer by using cv::VideoCapture.
like this, VideoCapture cap(“rtp://”);

But an error occured,
[rtp @ 006c1a60] Unable to receive RTP payload type 96 without an SDP file describing it

How can I get the SDP File?

I could solved it!

VideoCapture cap(“E:\workspace\of_v0.8.4_vs_release\apps\myApps\cvMjpegReceiver\stream.sdp”);

c=IN IP4
m=video 7000 RTP/AVP 96
a=rtpmap:96 H264/90000
