Some Matroska files have inaccurate ordered chapter endpoints, and so
parts where one chapter should end and the next begin at the same
timestamp were not merged. This resulted in an unnecessary seek over a
minimal distance. Add a heuristic to merge parts with a minimal gap or
overlap between them.
Based on patch by Hector Martin <hector@marcansoft.com>.
Add code to enforce matching pts with video when (re)starting the
audio stream, by either cutting away the first samples or inserting
silence at the beginning. New option -noinitial-audio-sync can be used
to disable this and return to old behavior.
If the option is enabled and all audio has been buffered to the AO,
then the player will move to the next file without waiting for the
buffered audio to drain, while leaving the AO initialized. If the
playback of the next file starts quickly enough (before the AO buffer
empties) then it should continue writing audio to the same AO with no
gap in between.
Commit 3f076c0fb3 ("options: move -a52drc to option struct") from
yesterday left out setting the default value of the option,
effectively changing the default from 1 to 0. Add the missing part to
change it back to 1.
-chapter can optionally take a range with a start and an end. Add a
new option type which supports such values and use that instead of a
custom per-option function.
This commit also fixes a build configuration bug: before the
availability of the -chapter option depended on DVD functionality
being enabled in the binary, even though the option works with other
sources too.
Add code to intelligently choose an appropriate Matroska edition when
there are several. Will choose, in descending order of preference: the
edition chosen by the user through the option "-edition <edition id>"
if it exists, the first edition with EditionFlagDefault set to 1 if
there is one, or the first edition.
As part of merging subtitle-in-terminal changes make
update_subtitles() only clear existing subtitles if called with the
reset argument, and not try to set new ones. Later calls should set
the needed new subtitles, and this change avoids some problems with
trying to set subtitles when mp_property_sub() in command.c gets
called from initialization code before full initialization.
Lack of -fixed-vo causes the output window to be recreated not only
when changing files but also when switching the video stream, and that
happens when moving from one ordered chapter source to another. Having
the window disappear and reappear (likely at another location if it
was ever moved) is just too annoying.
Name the field "sub_id" as it's not specific to DVD subs.
Remove some other unused extern declarations together with dvdsub_id
from demux_mkv.c and demux_lavf.c.
First part of option restructuring. The aim is to move option values
from a huge number of separate globals to a single non-global struct.
This part adds some support for parsing option values into such struct
instances, and moves one example option (fixed-vo) to the struct.
