Dust off those old DVD discs!
This version is greatly simplified and improved from the patch submitted in
December.
Discontinuity issues are resolved, and many discs should work smoothly out of
the box.
Also, GPL sector validation code is removed.
Basic Usage:
ffmpeg -f dvdvideo -title 1 -i PAT
I will add that I still had to maintain a dependency on GENPTS for the
inner MPEG demuxer. This is because dvdnav_get_current_time() does not
provide exact stream-level PTS. However, the crashing/hanging is fixed (by
parsing NAV packets), and the output is produced smoothly. GENPTS fills in

Thank you, Nicolas. I had tinkered with concat this way in the past as PGCs
are indeed just a bunch of segments mushed together, but I had run into
issues specifically with (1) concerns about forced subtitles that pop up
mid stream and (2) unable to figure out custom IO with it. Since dvdnav is

Looks OK (not tested).

Fixes for several authoring styles/discs.
ffmpeg CLI may report wrong output time and show progress strangely for some
discs.
This is not reproducible prior to `fftools/ffmpeg: convert to a threaded
architecture`
But, I am looking into it.

Fixes #10759.
It can happen in H.264, MPEG2, VC1 that the current frame resource
memory is already in ref_resource. For example, for a interlaced frame,
the same curr memory is passed twice. For the second time it could possibly
reference itself. When this happens the curr is alrea
