DVDNav current time

DVDNav module calculates the current time by taking the total time and then uses the block position to approximate the current playing time. Because of changing lenght of the blocksize this method is inaccurate.

A better method should be found, but this requires accessing the internal DVDread structure (see also [10144]). This functionality should be exposed from the dvdnav API and therefore requires libdvdnav development.

what does "see also [10144]" mean here?

Another manifestation of this, I believe:

[10144] used to mean Subversion revision 10144:

Offering $400 bounty if someone can fix this within dvdnav itself (also saw it mentioned on the dev ML recently). Thanks! -roger-

Appears that mplayer has some code to do this "right" for their OSD. Maybe it would be useful... http://betterlogic.com/roger/2011/01/mplayer-counter-resets-while-playing-a-dvd/ (last comment).

Original author: gnosygnu

See #3025 (closed)

if the changes from gnosygnu were accepted to libdvdnav, then this patch might work for VLC: https://gist.github.com/rdp/1390377 (use_dvdnav_jump_to_sector_by_time_vlc.diff file)

As we are forking libdvdnav, we do not care about what happens inside the old library.

The patch from gnosygnu was never merged because he did not adapt it to the new code.

I think it is present?

Would a more formal patch have a chance of being accepted, I'd be happy to come up with one. Cheers!

That would be very welcome, yes.
