I've been working with mp4 files with mpeg4ip libraries and it allowed me to specify the timing of each frame of video and audio tracks, and also you also have the hint tracks with the rtp timestamp and secuence number for more info. So I think that there would be no problems with lost packets for either playing or streaming the file.
