void CloseRTPFile

(

ImageParameters *

p_Img

)

Closes the bit stream file.

void DumpRTPHeader

(

RTPpacket_t *

p

)

DumpRTPHeader is a debug tool that dumps a human-readable interpretation of the RTP header.

Returns:

n.a.

Parameters:

p

the RTP packet to be dumped, after DecompositeRTPpacket()

Side effects

Debug output to stdout

int GetRTPNALU	(	ImageParameters *	p_Img,
		NALU_t *	nalu
	)

Fills nalu->buf and nalu->len with the payload of an RTP packet. Other fields in nalu-> remain uninitialized (will be taken care of by NALUtoRBSP.

Returns:

4 in case of ok (for compatibility with GetAnnexbNALU) 0 if there is nothing any more to read (EOF) -1 in case of any error

< triggers sequence number initialization on first call

< store the last RTP sequence number for loss detection
