[Mp4-tech] MPEG-4 reference code

[Jayant Chauhan]

I am trying to get a media player working which supports MP4 format.
Have it running now. I am using the reference MP4 parser provided by
ISO.
 I have to implement the Fast forward now. The problem is how do I
make my TrackReader jump to the particular Sample in a track.
 I can get the sample number in the track using the MP4MediaTimeToSampleNUm.
Currently, to play the video, we just do a
MP4TrackReaderGetNextAccessUnit, as in, traversing a link list. But
can we directly jump to a sample number and then traverse from there
???
