With current typical video sizes, font sizes are large enough that
they don't really need hinting (and particularly so for font sizes in
display-resolution rendered subtitles in fullscreen mode), and hinting
apparently causes problems with some fonts.
Add option --ass-vsfilter-aspect-compat and corresponding property
ass_vsfilter_aspect_compat. The setting controls whether to enable the
emulation of traditional VSFilter behavior where subtitles are
stretched if the video is anamorphic (previously always enabled for
native SSA/ASS subtitles). Enabled by default. Add 'V' as a new
default keybinding to toggle the property.
Rework much of the logic related to reading from event sources and
queuing commands. The two biggest architecture changes are:
- The code buffering keycodes in mp_fifo.c is gone. Instead key input
is now immediately fed to input.c and interpreted as commands, and
then the commands are buffered instead.
- mp_input_get_cmd() now always tries to read every available event
from every event source and convert them to (buffered) commands.
Before it would only process new events until one new command became
available.
Some relevant behavior changes:
- Before commands could be lost when stream code called
mp_input_check_interrupt() which read commands (to see if they were
of types that triggered aborts during slow IO tasks) and then threw
them away. This was especially an issue if cache was enabled and slow
to read. Fixed - now it's possible to check whether there are queued
commands which will abort playback of the current file without
throwing other commands away.
- mp_input_check_interrupt() now prints a message if it returns
true. This is especially useful because the failures caused by
aborted stream reads can trigger error messages from other code that
was doing the read; the new message makes it more obvious what the
cause of the subsequent error messages is.
- It's now possible to again avoid making stdin non-blocking (which
caused some issues) without reintroducing extra latency. The change
will be done in a subsequent commit.
- Event sources that do not support select() should now have somewhat
lower latency in certain situations as they will be checked both
before and after select()/sleep in input reading; before the sleep
always happened first even if such sources already had queued
input. Before the key fifo was also handled in this manner (first
key triggered select, but if multiple were read then rest could be
delayed; however in most cases this didn't add latency in practice
as after central code started doing command handling it queried for
further commands with a max sleep time of 0).
- Key fifo limiting is more accurate now: it now counts actual
commands intead of keycodes, and all queued keys are read
immediately from input devices so they can be counted correctly.
- Since keypresses are now interpreted immediately, commands which
change keybindings will no longer affect following keypresses that
have already been read before the command is executed. This should
not be an issue in practice with current keybinding behavior.

There are still some problems with -ass. For example some other
subtitle options won't work the same way or at all with it enabled,
and inserting the video filter for VOs that lack native rendering
support won't work with different colorspaces. However I think that
the benefit from styling support outweights those disadvantages, and
also that the "discoverability" of features is better this way; it
will be easier for people who encounter problems to find -noass than
for people who see no styling to find out that they could add it with
-ass.
Enable -ass by default. Also fix other outdated information in the
manpage entries for -ass and -fontconfig.
Make "-lavdopts threads=0" mean an autodetected number of threads, and
make that the default value of the option. Also increase the upper
limit of the option from 8 to 16. Add new file osdep/numcores.c which
tries to determine the number of cores available on the machine.
numcores.c is based (heavily modified) on public domain numcpus.c by
Philip Willoughby <pgw99@doc.ic.ac.uk>, downloaded from
http://csgsoft.doc.ic.ac.uk/numcpus/
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.
