GStreamer Video Capture and H264 Encoding with SEI

[steven414]

Hi，

I am trying to build an application which captures video from a Camera
(1920*1088).

The region 1920*1080 will be encoded into H264. While the region 1920*8 is
so-called embedded data, which should be extracted and added into SEI frame.
Then one original raw frame should become one I or P frame and one SEI frame
(embedded data). 

Currently I have built the pipeline to do the H264 encoding part like below:
camerasrc -> videoconvert -> h264enc -> h264parse -> rtph264pay -> udpsink

Now I wonder:
1. How to create a corresponding SEI frame from the 1920*8 cropped region. 
2. How to insert the SEI frame into H264 frame-by-frame.
