Chapters with 0 duration repeat the chapter title

[GoogleCodeExporter]

If you call MP4SetChapters with an array of chapters with different chapter
titles, but 0 durations, the first chapter title gets written to very
chapter.  I've attached a test program that creates this.

I don't doubt this is reproducible, but why would you want to create chapters 
with zero duration?

I have a movie tagging program, MetaX, and the user supplies the chapter names 
and durations.  Sometimes they have the chapter titles, but not the durations 
(due to the way they rip the DVD).  But I agree this isn't a big issue.

I looked into this more closely, and I think your best bet is to enforce a 
non-zero duration (i.e. if users enter zero, bump it up to something non-zero). 
 Basically, mp4v2 doesn't have a means of returning samples at the same time 
(so far as I can see) on the same track; it'll always return the first sample.  
It's up to libraries calling the API to correctly set track duration.

Let me know if this is an issue and I'll open the issue again and take another 
look.

OK, I'll just make the change in my code.
