 /**
+ * This is a utility function to decrypt SRTP packet using SRTP transport.
+ * This function is not part of SRTP transport's API, but it can be used
+ * to decrypt SRTP packets from non-network (for example, from a saved file)
+ * without having to use the transport framework. See pcaputil.c in the
+ * samples collection on how to use this function.
+ *
+ * @param tp            The SRTP transport.
+ * @param is_rtp        Set to non-zero if the packet is SRTP, otherwise set
+ *                      to zero if the packet is SRTCP.
+ * @param pkt           On input, it contains SRTP or SRTCP packet. On
+ *                      output, it contains the decrypted RTP/RTCP packet.
+ * @param pkt_len       On input, specify the length of the buffer. On
+ *                      output, it will be filled with the actual length
+ *                      of decrypted packet.
+ *
+ * @return              PJ_SUCCESS on success.
