VapourSynth introduced their version 4 API in R55, 3 years ago. mpv is
still using the deprecated version 3. I think it is good to migrate
before VapourSynth completely removes it.
The most impacted area is the video format. Previously we have a fixed
table of supported formats, each represented by an integer. In v4, the
integer is replaced by pointer to the full struct of the format.
Second, the way to create video filter is changed. Previously caller
needs to supply a "initialization" callback to `createFilter()`, which
sets up video info etc. In v4, video info is prepared first, passed to
the `createVideoFilter2()` and we get back the node.
Also, previously mpv was using the `fmSerial` filter mode, which means
VapourSynth 1) can only request one frame from mpv at a time, and 2) the
order of frames requested must be sequential. I propose to change it to
the parallel request mode, which requests multiple frames at a time in
semi random order. The reasons are, for 1), the get frame function,
`infiltGetFrame()`, unlocks the mutex during output image generation,
thus can benefit from parallel requests. For 2) thanks to the frame
buffer, unordered frame requests are acceptable. Just make sure the
buffer is large enough.
Third, the way VapourSynth scripting environment works change. In v4,
the scripting API is operated through struct pointer, much like the
exist `vsapi` pointer. The "finalize" function is also no longer needed.
Allow configuring whether to print the media-title, the filename or both
(as `<title> (<filename>)`) in show-text ${playlist}, the OSC playlist
and in the playlist selector.
Showing only titles hides information when files are badly tagged, or
when it hides the track numbers of album songs. But showing filenames is
not as useful as titles e.g. when playing URLs with media titles. This
option lets the user choose which one to show, or show both if switching
is inconvenient.
The OSC's playlist_media_title script-opt is removed because this option
is better since it works everywhere after configuring it once.
Closes#11653.
Also show the full URLs of playlist entries instead of their basenames
in osc.lua and select.lua, consistently with mp_property_playlist().
For simplicity, this just checks if entries contain :// instead of
replicating all of mp_is_url().

There is a subtle behavior difference for built-in/input.conf key bindings
and key bindings registered by scripts: when a key binding is canceled
(e.g. a mouse button is bound to a command, is pressed down, and then
another key is pressed which is bound to another command), the command is
not invoked if the binding is built-in/input.conf, but is invoked if it's
registered by scripts, because it's handled with a different mechanism,
which gives no way for scripts to detect this.
Fix this by using the newly available canceled flag to detect this.
If a key binding is canceled, the callback is now not invoked unless
the key binding is registered with the complex option. In this situation,
the callback is invoked with the canceled state available so that scripts
can detect and handle this situation.
This adds the --input-builtin-dragging option, which allows the built-in
dragging behavior to be disabled. This allows scripts to implement custom
dragging behavior with left button down events and begin-vo-dragging
command, which could only be done for other mouse buttons before.
This allows scripts to make the user choose from a list of entries by
typing part of their text and/or by navigating them with keybindings,
like dmenu or fzf.
Closes#13964.
For platforms which send emulated mouse inputs for touch-unaware clients,
such as Win32 and X11, this option enables the native multitouch handling
and disables emulated mouse inputs. This enables interested scripts to
handle multitouch events while keeping compatibility with touch-unaware
scripts.
This adds --input-touch-emulate-mouse option, which controls whether to
enable legacy touch handling where touch inputs are emulated as mouse
inputs. This establishes a primary touch point (the one with the lowest
index) as the emulated mouse position, and MBTN_LEFT up/down with the
appearance of the first touch point and the disappearance of the last
touch point.
This fixes some problems with touch handling on Wayland, for example
attempting to pinch results in a double click.
This adds touch-pos property, which contains the information of all
current touch points. The property has sub properties:
touch-pos/count: the number of current touch points
touch-pos/N/x,y: the position of touch point N
touch-pos/N/id: unique identifier of the touch point
This allows users to set buffer duration in exclusive mode. We have
been using the default device period as the buffer size and it is
robust enough in most cases. However, on some devices there are
horrible glitches after a stream reset. Unfortunately, the issue is not
consistently reproducible, but using a smaller buffer size (e.g., the
minimum device period) seems to resolve the problem.
Fixes#13715.
This gives these properties the "time" type, which allows them to be pretty-printed as HH:MM:SS easily (but also still allows raw formatting using e.g. ${=sub-start}).
Turns out that adding more medatata like HDR10+ and Dolby Vision would
produce a lot of duplication and it is better to centralize it around
the track-list property.
Fixes: e720159f72
Adds support for extracting codec profile. Old properties are redirected
to new one and removed from docs. Likely will stay like that forever as
there is no reason to remove them.
As a effect of unification of properties between audio and video,
video-codec will now print codec (format) descriptive name, not decoder
long name as it were before. In practice this change fixes what docs
says. If you really need decoder name, use the `track-list/N/decoder-desc`.
As far as I can tell PulseAudio introduced a bug in 16.0
where if a stream is (un)paused too often the reported latency
will momentarily spike by 3000% or more. Apparently in certain cases
just pausing once and waiting can also cause this.
Save the remaining users of PA the trouble of debugging the various
obscure issues that can arise from this (desync is a harmless example)
by enabling the latency hack code again.

Basically a simple way to perform any command/property action from the
command line. This takes the exact same syntax as input.conf but not
including the key naturally. Potentially useful for weird properties
that don't map well to options (like ao-volume). Fixes#12353.
This enhancement makes it easier to create constant width property
expansions, useful for the `--term-status-msg`. Additionally, it changes
to `%f` printing with manual zero trimming, which is easier to control
than `%g`. With this method, we can directly specify precision, not just
significant numbers. This approach also avoids overly high precision for
values less than 1, which is not necessary for a generic floating-point
print function.
A new print helper function is added, which can be used with adjusted
precision for specific cases where a different default is needed. This
also unifies the code slightly.
This adds a command to escape ASS tags to remove code duplication
between sub/osd_libass.c, console.lua, osc.lua, stats.lua and any user
script that calls mp.create_osd_overlay().
A command is used instead of scripting functions so that all clients can
use this and not just use Lua and JS ones.
osd_mangle_ass() also interprets osd-sym-cc and osd-ass-cc/{0,1}, but
since they use invalid UTF-8 characters there is no risk of escape-ass
users using them by accident, like with any OSD message.
Always replacing \n with \\N in mangle_ass() even when it is not called
by escape-ass doesn't seem to cause any issue, but I made it conditional
anyway to avoid changing how all OSD messages are treated unnecessarily.
There was no way for scripts to know the current size of the terminal,
which is essintial if they want to provide a good user experience even
without a window.
Manually editing interface-changes.rst is a giant maintenance pain that
causes merge conflicts all the time. Stop doing that nonsense and
instead have changes be written to files in DOCS/interface-changes. Also
remove that one sentence in changes.rst because it's just not true.
