RTP streaming file

-------------------

IVAS supports a simple packing and unpacking for streaming file for the RTP. In this format a single RTP_streaming_packet

contains the length of an RTP packet followed by the actual RTP packet which is recorded as-is. This format is produced

by the encoder when using the -rtpdump switch and the decoder assumes this format in the input when -VOIP_hf_only=1 is set.

typedef struct {

  u_int32 length;                   /* size of the RTP packet in bytes  */

  (u_int8 * length) RTP_packet;     /* RTP packet (sized length * byte) */

} RTP_streaming_packet;
