Note that a hint track sample is just like any other track sample. I.e MP4ReadSample(), MP4GetSampleSize(), MP4GetSampleTime(), etc. are all valid. The RTP specific functions are provided to interpret the information contain in the hint track samples that give instructions on how to form the actual RTP packets.
