This patch set starts with a critical bug fix to resolve packet drops,
then follows on with seeking support and menu chapter marker support.
In addition, some cleanup occurs and documentation/logging is improved.
Seeking can be tested with mpv,
```
/mpv "av://dvdvideo:$IN"
```
Compare/view on Git
DVDs naturally consist of segmented MPEG-PS blobs within a VOB
(i.e. VOBs are not linear). NAV packs set the segment boundaries.
When switching between segments, discontinuities occur and thus
the subdemuxer needs to be reset. The current approach to manage
this is by invoking ff_read_frame_flush()
Player applications can now enjoy seeking while playing back
a title. Accuracy is at the mercy of what libdvdnav offers,
which is currently dvdnav_jump_to_sector_by_time().

Menus can have chapter markers by way of cells, and empty menus
can be detected with existing functionality. Menu selection
also is in need of usability improvement.
Implement chapter markers for menus, let the trim function detect

As the comment implies, DOVIContext.ext_blocks should also reflect the
current state after ff_dovi_rpu_generate().
Fluff for now, but will be needed once we start implementing metadata
compression for extension blocks as well.

Is it possible to use this without using the portals API and without
systemd? That would be much appreciated if so since the portal is not very
flexible. As for systemd it would be great to be able to use this on

Hi Sean_McG, good day,
First of all, there is a typo in the commit message. It should say
"at the mercy of dvdnav_time_search()"
> I think avpriv_report_missing_feature() might be more appropriate here.
But there is no missing feature, the implementation is working great
with dvdnav_time_search()
I have found a whitespace error here and need to restore 2 lines of logic,
but will wait a few days for comment before putting up v2.

precision on existing hardware too low (!) for benchmarking purposes.
