int avf_sdp_create	(	AVFormatContext *	ac[],
		int	n_files,
		char *	buff,
		int	size
	)

Generate an SDP for an RTP session.

Parameters:

	ac	array of AVFormatContexts describing the RTP streams. If the array is composed by only one context, such context can contain multiple AVStreams (one AVStream per RTP stream). Otherwise, all the contexts in the array (an AVCodecContext per RTP stream) must contain only one AVStream
	n_files	number of AVCodecContexts contained in ac
	buff	buffer where the SDP will be stored (must be allocated by the caller
	size	the size of the buffer

Returns:

0 if OK. AVERROR_xxx if error.
