This became necessary now that more providers were added. Providers can
be proritized for certain file types (e.g. .vpy files will always be
opened with VapourSynth), and when the default provider fails on a file,
the user will be notified and be asked to pick an alternative provider.
This would cause an assertion failure in functions like lua_for_each
when the given closure throws an error and thus leaves some values on
the stack. This can make Aegisub crash entirely instead of just catching
and reporting the error. Instead, these stack_checks can be done
manually.
The highlighting distinguishes drawing commands from coordinates, and
colors x and y coordinates in different colors to make coordinates
easier to visually parse. Furthermore, in cubic Bezier curves, it
underlines the coordinates which corresponds to endpoints of the curves.
After the audio provider rework, adjust the audio players to not
use the int16 mono downmixed audio unless necessary. Furthermore,
the pulseaudio-based player now controls the volume directly through
pulseaudio instead of by modifying the buffer. This also reduces latency
when changing the volume.
The entire set of GetAudio functions is quite messy now. After wangqr's
audio rework, it was split into GetAudio and GetInt16MonoAudio
functions, but now volume scaling is also necessary. Really, this should
go back to a type constructor based system with audio players being
allowed to choose what properties out of mono / 16 bytes / int samples /
volume they need.
- To allow for XAudio2 to work properly, we need to rework how does provider work since they only are used to be able to take in mono audio.
- Other providers have been dumbed down to accept single channel audio since originally aegisub only accepted 1 channel audio.
- meson.build has been modified to accommodate for xaudio, as we currently don't accept redistributable forms of xaudio, we need to work around the WinNT version.
- There has been 1 more fix to res.rc to allow for compiling on non tagged releases.
boost::split_iterator type-erases the predicate, which makes it require
a virtual call per character (!) along with a heap allocation. As it
turns out we only ever need one predicate (comparing to a single
character), so replace it with a split_iterator that just does that.
Both size_t and unsigned long long are aliases for
unsigned __int64 on Win64, and causes a duplicate definition.
Replacing all the integer type_name definitions with stdint.h
names should avoid this problem.
It hasn't actually been used for anything for a while, and if a single
normal-priority thread can make your system unresponsive it's time to
upgrade to an OS that's isn't garbage.
