[vorbis] Bookmarks

[Corey Miller]

Keeping in mind that I don't know that much about ogg's tagging system 
or how you select a specific time in an ogg file, this seems like could 
probably be added pretty easily, but an even easier method would be too 
write it into the comments tag or something like that.  In the comments 
tag, since it holds a string, you could put something in it like 
"part1.1-00:00:00; part1.2-00:33:25;", basically 
"part#.#-minutes:seconds:milliseconds;"  You could then in your project 
write something to parse this, which would be pretty easy.  But that's 
just assuming you can retrieve minutes, seconds and milliseconds from a 
playing file and tell it to jump to a time using those units, I 
honestly don't know and don't have the time to find out right now, if 
ogg uses a single value for this it would probably be even easier, 
something like "part1.1-0; part1.2-455;" or if you don't care how it 
looks you use something like integer:integer-time; or float-time; so it 
would look like "1.2-1233;" and you could easily parse or write this 
kind of thing.  Come to think of it, if your really crazy about making 
this incredibly efficient, regardless of wether you make your own new 
tag or do it as I was suggesting, in the comments tag, you could just 
use two integers (or an integer and whatever vorbis returns the time 
in), so it might look like 8-442;13-1322 which would make two 
bookmarks, part0.8 at the point 442 and part1.3 at the point 1322.  I 
suppose if you make your own tag, the best way to do it would be to 
make it an array of numbers for the times, then just assume they go in 
order, so it would be {0,354,565,765,1200) which would be setting 
part1.1 to 0, part 1.2 to 354, etc.  I have to get ready to leave, so 
when I have some free time I'll look at how ogg handles tags and be 
able to give a more accurate response to this.
