<div>my question is:</div>
<div>1: If I must do some configuration before to use v4l2src?</div>
<div>2. How can I build gstream and it's plugin on my own?</div>
<div>3. I am not sure what must i do to capture video data from
RCA composite and compress to mp4:</div>
<div> I am using a board similar to DM37x Evaluation
Board(dm3730 on it)</div>
<div> If I understand right, the video data is from
RCA Composite to tvp5146, and to ISP module in cpu</div>
<div> My task is read data from RCA Composite, and encode
it to mp4. How can i do it?</div>
