Function Documentation

int av_sdp_create	(	AVFormatContext *	ac[],
		int	n_files,
		char *	buf,
		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
	buf	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 on error

int avf_sdp_create	(	AVFormatContext *	ac[],

	)

Definition at line 625 of file sdp.c.

void ff_sdp_write_media	(	char *	buff,
		int	size,
		AVCodecContext *	c,
		const char *	dest_addr,
		const char *	dest_type,
		int	port,
		int	ttl,
		AVFormatContext *	fmt
	)

Append the media-specific SDP fragment for the media stream c to the buffer buff.

Note, the buffer needs to be initialized, since it is appended to existing content.

Parameters:

	buff	the buffer to append the SDP fragment to
	size	the size of the buff buffer
	c	the AVCodecContext of the media to describe
	dest_addr	the destination address of the media stream, may be NULL
	dest_type	the destination address type, may be NULL
	port	the destination port of the media stream, 0 if unknown
	ttl	the time to live of the stream, 0 if not multicast
	fmt	the AVFormatContext, which might contain options modifying the generated SDP
