Raw Blame History

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 0.27.0 ---
- drop previously deprecated --field-dominance option
- drop previously deprecated "osd" command
- remove client API compatibility handling for "script", "sub-file",
"audio-file", "external-file" (these cases used to log a deprecation
warning)
- drop deprecated --video-aspect-method=hybrid option choice
- rename --hdr-tone-mapping to --tone-mapping (and generalize it)
- --opengl-fbo-format changes from a choice to a string. Also, its value
will be checked only on renderer initialization, rather than when the
option is set.
- Using opengl-cb now always assumes 8 bit per component depth, and dithers
to this size. Before, it tried to figure out the depth of the first
framebuffer that was ever passed to the renderer. Having GL framebuffers
with a size larger than 8 bit per component is quite rare. If you need
it, set the --dither-depth option instead.
--- mpv 0.26.0 ---
- remove remaining deprecated audio device options, like --alsa-device
Some of them were removed in earlier releases.
- introduce --replaygain... options, which replace the same functionality
provided by the deprecated --af=volume:replaygain... mechanism.
- drop the internal "mp-rawvideo" codec (used by --demuxer=rawvideo)
- rename --sub-ass-style-override to --sub-ass-override, and rename the
`--sub-ass-override=signfs` setting to `--sub-ass-override=scale`.
- change default of --video-aspect-method to "bitstream". The "hybrid"
method (old default) is deprecated.
- remove property "video-params/nom-peak"
- remove option --target-brightness
- replace vf_format's `peak` suboption by `sig-peak`, which is relative to
the reference white level instead of in cd/m^2
- renamed the TRCs `st2084` and `std-b67` to `pq` and `hlg` respectively
- the "osd" command is deprecated (use "cycle osd-level")
- --field-dominance is deprecated (use --vf=setfield=bff or tff)
- --really-quiet subtle behavior change
- the deprecated handling of setting "no-" options via client API is dropped
- the following options change to append-by-default (and possibly separator):
--script
also, the following options are deprecated:
--sub-paths => --sub-file-paths
the following options are deprecated for setting via API:
"script" (use "scripts")
"sub-file" (use "sub-files")
"audio-file" (use "audio-files")
"external-file" (use "external-files")
(the compatibility hacks for this will be removed after this release)
- remove property `vo-performance`, and add `vo-passes` as a more general
replacement
- deprecate passing multiple arguments to -add/-pre options (affects the
vf/af commands too)
- remove --demuxer-lavf-cryptokey. Use --demux-lavf-o=cryptokey=<hex> or
--demux-lavf-o=decryption_key=<hex> instead (whatever fits your situation).
- rename --opengl-dumb-mode=no to --opengl-dumb-mode=auto, and make `no`
always disable it (unless forced on by hardware limitation).
- generalize --scale-clamp, --cscale-clamp etc. to accept a float between
0.0 and 1.0 instead of just being a flag. A value of 1.0 corresponds to
the old `yes`, and a value of 0.0 corresponds to the old `no`.
--- mpv 0.25.0 ---
- remove opengl-cb dxva2 dummy hwdec interop
(see git "vo_opengl: remove dxva2 dummy hwdec backend")
- remove ppm, pgm, pgmyuv, tga choices from the --screenshot-format and
--vo-image-format options
- the "jpeg" choice in the option above now leads to a ".jpg" file extension
- --af=drc is gone (you can use e.g. lavfi/acompressor instead)
- remove image_size predefined uniform from OpenGL user shaders. Use
input_size instead
- add --sub-filter-sdh
- add --sub-filter-sdh-harder
- remove --input-app-events option (macOS)
- deprecate most --vf and --af filters. Only some filters not in libavfilter
will be kept.
Also, you can use libavfilter filters directly (e.g. you can use
--vf=name=opts instead of --vf=lavfi=[name=opts]), as long as the
libavfilter filter's name doesn't clash with a mpv builtin filter.
In the long term, --vf/--af syntax might change again, but if it does, it
will switch to libavfilter's native syntax. (The above mentioned direct
support for lavfi filters still has some differences, such as how strings
are escaped.) If this happens, the non-deprecated builtin filters might be
moved to "somewhere else" syntax-wise.
- deprecate --loop - after a deprecation period, it will be undeprecated,
but changed to alias --loop-file
- add --keep-open-pause=no
- deprecate --demuxer-max-packets
- change --audio-file-auto default from "exact" to "no" (mpv won't load
files with the same filename as the video, but different extension, as
audio track anymore)
--- mpv 0.24.0 ---
- deprecate --hwdec-api and replace it with --opengl-hwdec-interop.
The new option accepts both --hwdec values, as well as named backends.
A minor difference is that --hwdec-api=no (which used to be the default)
now actually does not preload any interop layer, while the new default
("") uses the value of --hwdec.
- drop deprecated --ad/--vd features
- drop deprecated --sub-codepage syntax
- rename properties:
- "drop-frame-count" to "decoder-frame-drop-count"
- "vo-drop-frame-count" to "frame-drop-count"
The old names still work, but are deprecated.
- remove the --stream-capture option and property. No replacement.
(--record-file might serve as alternative)
- add --sub-justify
- add --sub-ass-justify
- internally there's a different way to enable the demuxer cache now
it can be auto-enabled even if the stream cache remains disabled
--- mpv 0.23.0 ---
- remove deprecated vf_vdpaurb (use "--hwdec=vdpau-copy" instead)
- the following properties now have new semantics:
- "demuxer" (use "current-demuxer")
- "fps" (use "container-fps")
- "idle" (use "idle-active")
- "cache" (use "cache-percent")
- "audio-samplerate" (use "audio-params/samplerate")
- "audio-channels" (use "audio-params/channel-count")
- "audio-format" (use "audio-codec-name")
(the properties equivalent to the old semantics are in parentheses)
- remove deprecated --vo and --ao sub-options (like --vo=opengl:...), and
replace them with global options. A somewhat complete list can be found
here: https://github.com/mpv-player/mpv/wiki/Option-replacement-list#mpv-0210
- remove --vo-defaults and --ao-defaults as well
- remove deprecated global sub-options (like -demuxer-rawaudio format=...),
use flat options (like --demuxer-rawaudio-format=...)
- the --sub-codepage option changes in incompatible ways:
- detector-selection and fallback syntax is deprecated
- enca/libguess are removed and deprecated (behaves as if they hadn't
been compiled-in)
- --sub-codepage=<codepage> does not force the codepage anymore
(this requires different and new syntax)
- remove --fs-black-out-screens option for macOS
- change how spdif codecs are selected. You can't enable spdif passthrough
with --ad anymore. This was deprecated; use --audio-spdif instead.
- deprecate the "family" selection with --ad/--vd
forcing/excluding codecs with "+", "-", "-" is deprecated as well
- explicitly mark --ad-spdif-dtshd as deprecated (it was done so a long time
ago, but it didn't complain when using the option)
--- mpv 0.22.0 ---
- the "audio-device-list" property now sets empty device description to the
device name as a fallback
- add --hidpi-window-scale option for macOS
- add audiounit audio output for iOS
- make --start-time work with --rebase-start-time=no
- add --opengl-early-flush=auto mode
- add --hwdec=vdpau-copy, deprecate vf_vdpaurb
- add tct video output for true-color and 256-color terminals
--- mpv 0.21.0 ---
- unlike in older versions, setting options at runtime will now take effect
immediately (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 0.23.0.
- 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 0.23.0. 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 0.23.0: 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 0.23.0.
- deprecate mp.suspend(), mp.resume(), mp.resume_all() Lua scripting
commands, as well as setting mp.use_suspend. They will be completely
removed in 0.23.0.
- 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 ---
