Introduction
============
mpv provides access to its internals via the following means:
- options
- commands
- properties
- events
All of these are important for interfacing both with end users and API users
(which include Lua scripts, libmpv, and the JSON IPC). As such, they constitute
a large part of the user interface and APIs.
This document lists changes to them. New changes are added to the top.
Interface changes
=================
::
--- mpv 0.21.0 ---
- setting certain options at runtime will now take care of updating them
property (see for example issue #3281). On the other hand, it will also
do runtime verification and reject option changes that do not work
(example: setting the "vf" option to a filter during playback, which fails
to initialize - the option value will remain at its old value). In general,
"set name value" should be mostly equivalent to "set options/name value"
in cases where the "name" property is not deprecated and "options/name"
exists - deviations from this are either bugs, or documented as caveats
in the "Inconsistencies between options and properties" manpage section.
- deprecate _all_ --vo and --ao suboptions. Generally, all suboptions are
replaced by global options, which do exactly the same. For example,
"--vo=opengl:scale=nearest" turns into "--scale=nearest". In some cases,
the global option is prefixed, e.g. "--vo=opengl:pbo" turns into
"--opengl-pbo".
Most of the exact replacements are documented here:
https://github.com/mpv-player/mpv/wiki/Option-replacement-list
- remove --vo=opengl-hq. Set --profile=opengl-hq instead. Note that this
profile does not force the VO. This means if you use the --vo option to
set another VO, it won't work. But this also means it can be used with
opengl-cb.
- remove the --vo=opengl "pre-shaders", "post-shaders" and "scale-shader"
sub-options: they were deprecated in favor of "user-shaders"
- deprecate --vo-defaults (no replacement)
- remove the vo-cmdline command. You can set OpenGL renderer options
directly via properties instead.
- deprecate the device/sink options on all AOs. Use --audio-device instead.
- deprecate "--ao=wasapi:exclusive" and "--ao=coreaudio:exclusive",
use --audio-exclusive instead.
- subtle changes in how "--no-..." options are treated mean that they are
not accessible under "options/..." anymore (instead, these are resolved
at parsing time). This does not affect options which start with "--no-",
but do not use the mechanism for negation options.
(Also see client API change for API version 1.23.)
- rename the following properties
- "demuxer" -> "current-demuxer"
- "fps" -> "container-fps"
- "idle" -> "idle-active"
- "cache" -> "cache-percent"
the old names are deprecated and will change behavior in mpv 0.22.0.
- remove deprecated "hwdec-active" and "hwdec-detected" properties
- deprecate the ao and vo auto-profiles (they never made any sense)
- deprecate "--vo=direct3d_shaders" - use "--vo=direct3d" instead.
Change "--vo=direct3d" to always use shaders by default.
- deprecate --playlist-pos option, renamed to --playlist-start
- deprecate the --chapter option, as it is redundant with --start/--end,
and conflicts with the semantics of the "chapter" property
- rename --sub-text-* to --sub-* and --ass-* to --sub-ass-* (old options
deprecated)
- incompatible change to cdda:// protocol options: the part after cdda://
now always sets the device, not the span or speed to be played. No
separating extra "/" is needed. The hidden --cdda-device options is also
deleted (it was redundant with the documented --cdrom-device).
- deprecate --vo=rpi. It will be removed in mpv 0.22.0. Its functionality
was folded into --vo=opengl, which now uses RPI hardware decoding by
treating it as a hardware overlay (without applying GL filtering). Also
to be changed in 0.22.0: the --fs flag will be reset to "no" by default
(like on the other platforms).
- deprecate --mute=auto (informally has been since 0.18.1)
- deprecate "resume" and "suspend" IPC commands. They will be completely
removed in 0.22.0.
- deprecate mp.suspend(), mp.resume(), mp.resume_all() Lua scripting
commands, as well as setting mp.use_suspend. They will be completely
removed in 0.22.0.
- the "seek" command's absolute seek mode will now interpret negative
seek times as relative from the end of the file (and clamps seeks that
still go before 0)
- add almost all options to the property list, meaning you can change
options without adding "options/" to the property name (a new section
has been added to the manpage describing some conflicting behavior
between options and properties)
- implement changing sub-speed during playback
- make many previously fixed options changeable at runtime (for example
--terminal, --osc, --ytdl, can all be enable/disabled after
mpv_initialize() - this can be extended to other still fixed options
on user requests)
--- mpv 0.20.0 ---
- add --image-display-duration option - this also means that image duration
is not influenced by --mf-fps anymore in the general case (this is an
incompatible change)
--- mpv 0.19.0 ---
- deprecate "balance" option/property (no replacement)
--- mpv 0.18.1 ---
- deprecate --heartbeat-cmd
- remove --softvol=no capability:
- deprecate --softvol, it now does nothing
- --volume, --mute, and the corresponding properties now always control
softvol, and behave as expected without surprises (e.g. you can set
them normally while no audio is initialized)
- rename --softvol-max to --volume-max (deprecated alias is added)
- the --volume-restore-data option and property are removed without
replacement. They were _always_ internal, and used for watch-later
resume/restore. Now --volume/--mute are saved directly instead.
- the previous point means resuming files with older watch-later configs
will print an error about missing --volume-restore-data (which you can
ignore), and will not restore the previous value
- as a consequence, volume controls will no longer control PulseAudio
per-application value, or use the system mixer's per-application
volume processing
- system or per-application volume can still be controlled with the
ao-volume and ao-mute properties (there are no command line options)
--- mpv 0.18.0 ---
- now ab-loops are active even if one of the "ab-loop-a"/"-b" properties is
unset ("no"), in which case the start of the file is used if the A loop
point is unset, and the end of the file for an unset B loop point
- deprecate --sub-ass=no option by --ass-style-override=strip
(also needs --embeddedfonts=no)
- add "hwdec-interop" and "hwdec-current" properties
- deprecated "hwdec-active" and "hwdec-detected" properties (to be removed
in mpv 0.20.0)
- choice option/property values that are "yes" or "no" will now be returned
as booleans when using the mpv_node functions in the client API, the
"native" property accessors in Lua, and the JSON API. They can be set as
such as well.
- the VO opengl fbo-format sub-option does not accept "rgb" or "rgba"
anymore
- all VO opengl prescalers have been removed (replaced by user scripts)
--- mpv 0.17.0 ---
- deprecate "track-list/N/audio-channels" property (use
"track-list/N/demux-channel-count" instead)
- remove write access to "stream-pos", and change semantics for read access
- Lua scripts now don't suspend mpv by default while script code is run
- add "cache-speed" property
- rename --input-unix-socket to --input-ipc-server, and make it work on
Windows too
- change the exact behavior of the "video-zoom" property
- --video-unscaled no longer disables --video-zoom and --video-aspect
To force the old behavior, set --video-zoom=0 and --video-aspect=0
--- mpv 0.16.0 ---
- change --audio-channels default to stereo (use --audio-channels=auto to
get the old default)
- add --audio-normalize-downmix
- change the default downmix behavior (--audio-normalize-downmix=yes to get
the old default)
- VO opengl custom shaders must now use "sample_pixel" as function name,
instead of "sample"
- change VO opengl scaler-resizes-only default to enabled
- add VO opengl "interpolation-threshold" suboption (introduces new default
behavior, which can change e.g. ``--video-sync=display-vdrop`` to the
worse, but is usually what you want)
- make "volume" and "mute" properties changeable even if no audio output is
active (this gives not-ideal behavior if --softvol=no is used)
- add "volume-max" and "mixer-active" properties
- ignore --input-cursor option for events injected by input commands like
"mouse", "keydown", etc.
--- mpv 0.15.0 ---
- change "yadif" video filter defaults
--- mpv 0.14.0 ---
- vo_opengl interpolation now requires --video-sync=display-... to be set
- change some vo_opengl defaults (including changing tscale)
- add "vsync-ratio", "estimated-display-fps" properties
- add --rebase-start-time option
This is a breaking change to start time handling. Instead of making start
time handling an aspect of different options and properties (like
"time-pos" vs. "playback-time"), make it dependent on the new option. For
compatibility, the "time-start" property now always returns 0, so code
which attempted to handle rebasing manually will not break.
--- mpv 0.13.0 ---
- remove VO opengl-cb frame queue suboptions (no replacement)
--- mpv 0.12.0 ---
- remove --use-text-osd (useless; fontconfig isn't a requirement anymore,
and text rendering is also lazily initialized)
- some time properties (at least "playback-time", "time-pos",
"time-remaining", "playtime-remaining") now are unavailable if the time
is unknown, instead of just assuming that the internal playback position
is 0
- add --audio-fallback-to-null option
- replace vf_format outputlevels suboption with "video-output-levels" global
property/option; also remove "colormatrix-output-range" property
- vo_opengl: remove sharpen3/sharpen5 scale filters, add sharpen sub-option
--- mpv 0.11.0 ---
- add "af-metadata" property
--- mpv 0.10.0 ---
- add --video-aspect-method option
- add --playlist-pos option
- add --video-sync* options
"display-sync-active" property
"vo-missed-frame-count" property
"audio-speed-correction" and "video-speed-correction" properties
- remove --demuxer-readahead-packets and --demuxer-readahead-bytes
add --demuxer-max-packets and --demuxer-max-bytes
(the new options are not replacement and have very different semantics)
- change "video-aspect" property: always settable, even if no video is
running; always return the override - if no override is set, return
the video's aspect ratio
- remove disc-nav (DVD, BD) related properties and commands
- add "option-info/<name>/set-locally" property
- add --cache-backbuffer; change --cache-default default to 75MB
the new total cache size is the sum of backbuffer and the cache size
specified by --cache-default or --cache
- add ``track-list/N/audio-channels`` property
- change --screenshot-tag-colorspace default value
- add --stretch-image-subs-to-screen
- add "playlist/N/title" property
- add --video-stereo-mode=no to disable auto-conversions
- add --force-seekable, and change default seekability in some cases
- add vf yadif/vavpp/vdpaupp interlaced-only suboptions
Also, the option is enabled by default (Except vf_yadif, which has
it enabled only if it's inserted by the deinterlace property.)
- add --hwdec-preload
- add ao coreaudio exclusive suboption
- add ``track-list/N/forced`` property
- add audio-params/channel-count and ``audio-params-out/channel-count props.
- add af volume replaygain-fallback suboption
- add video-params/stereo-in property
- add "keypress", "keydown", and "keyup" commands
- deprecate --ad-spdif-dtshd and enabling passthrough via --ad
add --audio-spdif as replacement
- remove "get_property" command
- remove --slave-broken
- add vo opengl custom shader suboptions (source-shader, scale-shader,
pre-shaders, post-shaders)
- completely change how the hwdec properties work:
- "hwdec" now reflects the --hwdec option
- "hwdec-detected" does partially what the old "hwdec" property did
(and also, "detected-hwdec" is removed)
- "hwdec-active" is added
- add protocol-list property
- deprecate audio-samplerate and audio-channels properties
(audio-params sub-properties are the replacement)
- add audio-params and audio-out-params properties
- deprecate "audio-format" property, replaced with "audio-codec-name"
- deprecate --media-title, replaced with --force-media-title
- deprecate "length" property, replaced with "duration"
- change volume property:
- the value 100 is now always "unchanged volume" - with softvol, the
range is 0 to --softvol-max, without it is 0-100
- the minimum value of --softvol-max is raised to 100
- remove vo opengl npot suboption
- add relative seeking by percentage to "seek" command
- add playlist_shuffle command
- add --force-window=immediate
- add ao coreaudio change-physical-format suboption
- remove vo opengl icc-cache suboption, add icc-cache-dir suboption
- add --screenshot-directory
- add --screenshot-high-bit-depth
- add --screenshot-jpeg-source-chroma
- default action for "rescan_external_files" command changes
--- mpv 0.9.0 ---
