Missing controls: Jump to prev/next chapter

[GoogleCodeExporter]

gnome-mplayer is lacking controls to jump to previous (key: !)/next(key: @)
chapter in dvd and "normal" movie mode (eg. MKV files).

I've added this for DVDs and DVDs with menus. If you could send me the output 
of 

mplayer -identify [some mkv file] -frames 0

Of a file that contains chapters, so that I can make sure my code picks it up.

Here's your info (Jumping to the chapter marks works perfect via !/@ with that 
file,
only the controls are missing):

I don't see anything in there, that says that the file has chapters. If it 
doesn't
report them, then I can't detect them.

Yap, noticed that, too. Hitting the keyboard shortcuts on a non chaptered file
doesn't effect playback, thou maybe it's a solution to offer chapter controls 
as some
settings switch (something like "Always show chapter controls").

The problem, with the chapter controls, is that those controls also are used to
advance to the next media file when there are multiple items on the playlist. 
So from
a coding standpoint, I really need to know if there are chapters or not. And if 
you
have a single item on the playlist, I don;t show the previous and next (chapter 
/
file) buttons.. So there are some definite interface issues.

Submitted a patch to mplayer 
http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2008-September/058567.html

If this patch is accepted and I think it should be, in addition to some 
additional
things I have committed to the gnome-mplayer code, this should be working for 
MKV
files now.

Hi, what actually is supposed to be the state of DVD chapter controls?
For me it only navigates DVD "titles" - not "chapters", which would be rather 
nice to
be able to navigate as well :)
Ideally for DVD navigation I think you'd want a cascading drop-down or 
right-click
menu like gmplayer, but I guess it depends how far you want to go with this 
sort of
thing - you could add an eject button and a setting to choose which optical 
drive to
use if there is more than one and all sorts of other things.
Another thing that would be nice is the ability to add something to the 
playlist when
you use File-Open, instead of just replacing the playlist.

OK, sorry - it seems I was using a strange disc.  I must usually use the 
right-click
menu to select chapters in gmplayer, because that works on this disc, but the >|
button doesn't.
