MATLAB: Format (Byte) of UDP packets from VLC

MATLABstreamudpvlc

I am trying to read udp packets by streaming an mp3 from vlc player and receiving packets in matlab. I successfully received the packets but the problem is that i want to decode the packets.
Address in VLC is 127.0.0.1 and port is 1234. Now how to write a decoder, I cant find any Byte Information on Internet or VLC forums. Can some please help me with this. The code i used is given below and received packets are also attached. 
u = udp('', 'LocalHost', '', 'LocalPort', 1234,'ByteOrder','littleEndian');
fopen(u);
packetData = zeros(512,100,'uint8');
tic;
for i = 1:100
    % Receive a single UDP packet
    packetData(:,i) = uint8(fread(u));
end
toc;
fclose(u);
The packet is attached.
