This has a number of user-visible changes:
1. A new flag blend-subtitles (default on for opengl-hq) to control this
behavior.
2. The OSD itself will not be color managed or affected by
gamma controls. To get subtitle CMS/gamma, blend-subtitles must be
used.
3. When enabled, this will make subtitles be cleanly interpolated by
:interpolation, and also dithered etc. (just like the normal output).

Bilinear scaling is not a suitable default for something named "hq"; the
whole reason this was done in the past was because cscale used to be
obscenely slow. This is no longer the case, with cscale being nearly
free.
Why did this exist in the first place? Other than being completely
useless, this even caused some regressions in the past. For example,
there was the case of a laptop exposing its accelerometer as joystick
device, which led to extremely fun things due to the default mappings of
axis movement being mapped to seeking.
I suppose those who really want to use their joystick to control a media
player (???) can configure it as mouse device or so.
This replaces the old smoothmotion code by a more flexible tscale
option, which essentially allows any scaler to be used for interpolating
frames. (The actual "smoothmotion" scaler which behaves identical to the
old code does not currently exist, but it will be re-added in a later commit)
The only odd thing is that larger filters require a larger queue size
offset, which is currently set dynamically as it introduces some issues
when pausing or framestepping. Filters with a lower radius are not
affected as much, so this is identical to the old smoothmotion if the
smoothmotion interpolator is used.
I think this is what I alwass missed ever since I found the MPlayer
cache options: a way to enable the cache on local files with the default
settings, whatever they are.
Requested change in behavior.
Note that we set the assumed "infinite" display_fps to 1e6, which
conveniently lets vo_get_vsync_interval() return a dummy value of 1,
which can be easily checked against, and still avoids doing math with
float INFs.
This adds stuff related to gamma, linear light, sigmoid, BT.2020-CL,
etc, as well as color management. Also adds a new gamma function (gamma22).
This adds new parameters to configure the CMS settings, in particular
letting us target simple colorspaces without requiring usage of a 3DLUT.
This adds smoothmotion. Mostly working, but it's still sensitive to
timing issues. It's based on an actual queue now, but the queue size
is kept small to avoid larger amounts of latency.
Also makes “upscale before blending” the default strategy.
This is justified because the "render after blending" thing doesn't seme
to work consistently any way (introduces stutter due to the way vsync
timing works, or something), so this behavior is a bit closer to master
and makes pausing/unpausing less weird/jumpy.
This adds the remaining scalers, including bicubic_fast, sharpen3,
sharpen5, polar filters and antiringing. Apparently, sharpen3/5 also
consult scale-param1, which was undocumented in master.
This also implements cropping and chroma transformation, plus
rotation/flipping. These are inherently part of the same logic, although
it's a bit rough around the edges in some case, mainly due to the fallback
code paths (for bilinear scaling without indirection).
Move the command line parsing and some other things to the common init
routine shared between command line player and client API. This means
they're using almost exactly the same code now.
The main intended side effect is that the client API will load mpv.conf;
though still only if config loading is enabled.
(The cplayer still avoids creating an extra thread, passes a command
line, and prints an exit status to the terminal. It also has some
different defaults.)
This gets rid of the need for a second (or more) parameters; instead it
can be all in one parameter. The (now) redundant parameter is still
parsed for compatibility, though.
The way the flags make each other conflict is a bit tricky: they have
overlapping bits, and the option parser disallows setting already set
bits.
This automatically sets the gamma option depending on lighting conditions
measured from the computer's ambient light sensor.
sRGB – arguably the “sibling” to BT.709 for still images – has a reference
viewing environment defined in its specification (IEC 61966-2-1:1999, see
http://www.color.org/chardata/rgb/srgb.xalter). According to this data, the
assumed ambient illuminance is 64 lux. This is the illuminance where the gamma
that results from ICC color management is correct.
On the other hand, BT.1886 formalizes that the gamma level for dim environments
to be 2.40, and Apple resources (WWDC12: 2012 Session 523: Best practices for
color management) define the BT.1886 dim at 16 lux.
So the logic we apply is:
* >= 64lux -> 1.961 gamma
* =< 16lux -> 2.400 gamma
* 16lux < x < 64lux -> logaritmic rescale of lux to gamma. The human
perception of illuminance roughly follows a logaritmic scale of lux [1].

Breaks vo_opengl by default. I'm hot able to fix this myself, because I
have no clue about the overcomplicated color management logic. Also,
whilethis is apparently caused by commit fbacd5, the following commits
all depend on it, so revert them too.
This reverts the following commits:
e141caa97d653b0dd529729c8b3f64fbacd5de31Fixes#1636.
Just use makeFirstResponder on the mpv events view from client code
if you need the built in keyboard events (this is easier for dealing with view
nesting).
This relies on upstream support in lavc, and will hence basically not
work at all. The intent is to get support for writing this information
into ffmpeg's PNG encoders etc.
Now that we have fast stream switching, we can bump these sizes, as the
queues cause no delay in switching anymore.
Of course, the fast stream switching works for mkv and mp4 only. Other
formats will incur a quite terrible delay especially in network mode,
which this commit changes to 10 seconds. Let's see if someone
complains...
The way I interpreted it, it seemed like this was not default behavior
and could be enabled with --audio-pitch-correction - it should be made
clearer that this is actually *the default behavior*.
This is based on pretty much the same (somewhat naive) logic right now.
I'm not convinced that the extra logic that eg. madVR includes is worth
enough to warrant heavily confusing the logic for it.
This shouldn't slow down the logic at all in any sane shader compiler,
and indeed it doesn't on any shader compiler that I tested.
Note that this currently doesn't affect cscale at all, due to the weird
implementation details of that.
This option allows the user to pass non-supported options directly to
youtube-dl, such as "--proxy URL", "--username USERNAME" and
'--password PASSWORD".
There is no sanity checking so it's possible to break things (i.e.
if you pass "--version" mpv exits with random JSON error).

Hopefully, this will really clear up how the thing is supposed to work
(and that it's not SVP, nor MVTools).
I also removed instances of the word "interpolation", since that's a
term that's easily misleading.
Finally, I expanded on smoothmotion-threshold since the purpose/meaning
was a bit confusing.
