Function Documentation

ff_sdp_write_media()

int ff_sdp_write_media	(	char *	buff,
		int	size,
		const AVStream *	st,
		int	idx,
		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
st	the AVStream of the media to describe
idx	the global stream index
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

Returns

0 on success, a negative error code on failure
