Here is the call graph for this function:

int rewrite_paramsets	(	ImageParameters *	p_Img,
		InputParameters *	p_Inp
	)

This function opens the output files and generates the appropriate sequence header.

As a sequence header, here we write both sequence and picture parameter sets. As soon as IDR is implemented, this should go to the IDR part, as both parsets have to be transmitted as part of an IDR. An alternative may be to consider this function the IDR start function.

Lets write now the Picture Parameter sets. Output will be equal to the total number of bits spend here.
