[MPlayer-users] Request for more verbose information from dvds

[Chris Phillips]

Hi developers

If anyones been reading those emails from me on the last few days about a 
perl wrapper for encoding dvd's I've been struggling to find ways to get 
accurate information about the contents of a dvd. i've had some success 
with vstrip, to deduce where the main title of a dvd is, but when i come 
to something really complex, such as monsters inc which has silly games 
and such like in it, everything goes very much tits up, so to speak.

I know from vstrip that the info for stream lengths and such is all out 
there, and also that when mplayer plays a dvd it parses all the dvd to 
find the total number of titles etc, so PLEASE PLEASE PLEASE can some 
extra verbose information be added (i.e. when the -v flag is used) to list 
information similar to the number AND length of titles on the disc so an 
external script can actually use the information to make a ripping GUI for 
mencoder or such like to be feasible. 

I know that the cropdetect option give out suitable information for 
parsing, so that's great, and it's easy to get information on what 
languages are present in a title etc. but it would really be great to be 
able to get some more information about a dvd from mplayer itself, and not
need to use vstrip of similar apps.

I have tried reading the source to find where the titles are read, and 
found various things inside libmpdemux and the libmpdvdkit2, but not found 
anything i think i could base a patch, or such like, around.

Thanks 

Chris
