        @Nullable
public static RtpPacket parse​(byte[] buffer,
                              int length)
        Deprecated.
        Creates an RtpPacket from a byte array.
        Parameters:
        buffer - The buffer that contains the RTP packet data.
        length - The length of the RTP packet.
        Returns:
        The built RtpPacket.

      • writeToBuffer

        Deprecated.
        Writes the data in an RTP packet to a target buffer.

        The size of the target buffer and the length argument should be big enough so that the entire RTP packet could fit. That is, if there is not enough space to store the entire RTP packet, no bytes will be written. The maximum size of an RTP packet is defined as MAX_SIZE.

        Parameters:
        target - A target byte buffer to which the packet data is copied.
        offset - The offset into the target array at which to write.
        length - The maximum number of bytes that can be written.
        Returns:
        The number of bytes written, or C.LENGTH_UNSET if there is not enough space to write the packet.
