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
