* H264 RTP packetization by Vitaly V. Bursov <vitalyvb at ukr dotnet> refs #132 

NAL and FU-A modes of RFC 3984
  works for VLC -> VLC
  Does not work with QT yet, because QT requires the optional params profile-level-id and sprop-parameter-sets. these are usually provided in QT hinted tracks I guess. I'm not sure if we can reconstruct them manually. If someone would care to investigate..
