Yes, I would like ffmpeg should generate frame when it finds first I frame.

If it gives initial gray color frame then it definately means that it did not find I-frame thati s why ffmpeg keeps on inserting dummy frames.

I dont have any idea which command does this removing gray color frames. We need to change something in coding. Where should we change that I am still figuring out. If you have any idea how we should keep on drop the frame till we get I frame then it may solve my purpose.

Do you mean that you want the output to start from the point where you get an I-frame?  That could potentially be a long time in the future -- I've had to deal with streams that went several minutes between I-frames.
