Getting Raw data from Raspberry pi

[Aditya Oza]

hello,

I used raspberry pi 3b+ camera for streaming and recording .

My goal Is I want  raw data.

I used following pipeline :
 
gst-launch-1.0 --gst-debug-level=3 -e v4l2src device=/dev/video0 ! videoconvert ! video/x-raw,width=640,height=480,framerate=30/1 ! tee name=tee0 ! queue ! omxh264enc ! h264parse ! mp4mux ! filesink location=raw.mp4 tee0. ! queue ! appsink

After run this pipeline I did not get proper data.. Just create 4kb mp4 file. when I try to play a file(4 kb)they could not be open. 

my log:

Setting pipeline to PAUSED ...

Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...

Please suggest me when I am wrong?
 
suggest me a better way to get raw data from my camera.
