[libbluray-devel] PTS and DTS of Blu-Ray titles made of multiple files

Dear all,

I have just implemented (thanks to libbluray) unencrypted Blu-Ray support
into a movie player that I'm developing.


Basic playback seems to work quite good for now, except for one thing.


The movie player uses audio and video pts (and dts) to keep audio and video
in sync and it works fine for every movie file (non blu-ray) and for blu-ray
titles which are made of only one file (for the entire movie).


When blu-ray title is made of multiple files which have to be concatenated
seamlessly, the all procedure of audio/video syncing fails as soon as file
change is reached. 

This is given by the fact that audio and video PTS of the new file and the
one of the previous file are not contiguous..they actually start over.


Am I responsable of managing this discontinuity in audio/video PTS or does
libbluray provide some API to handle this?
