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 0.29.0 ---
|
|
- drop deprecated --videotoolbox-format, --ff-aid, --ff-vid, --ff-sid,
|
|
--ad-spdif-dtshd, --softvol options
|
|
--- mpv 0.28.0 ---
|
|
- rename --hwdec=mediacodec option to mediacodec-copy, to reflect
|
|
conventions followed by other hardware video decoding APIs
|
|
- drop previously deprecated --heartbeat-cmd and --heartbeat--interval
|
|
options
|
|
- rename --vo=opengl to --vo=gpu
|
|
- rename --opengl-backend to --gpu-context
|
|
- rename --opengl-shaders to --glsl-shaders
|
|
- rename --opengl-shader-cache-dir to --gpu-shader-cache-dir
|
|
- rename --opengl-tex-pad-x/y to --gpu-tex-pad-x/y
|
|
- rename --opengl-fbo-format to --fbo-format
|
|
- rename --opengl-gamma to --gamma-factor
|
|
- rename --opengl-debug to --gpu-debug
|
|
- rename --opengl-sw to --gpu-sw
|
|
- rename --opengl-vsync-fences to --swapchain-depth, and the interpretation
|
|
slightly changed. Now defaults to 3.
|
|
- rename the built-in profile `opengl-hq` to `gpu-hq`
|
|
- the semantics of --opengl-es=yes are slightly changed -> now requires GLES
|
|
- remove the (deprecated) alias --gpu-context=drm-egl
|
|
- remove the (deprecated) --vo=opengl-hq
|
|
- remove --opengl-es=force2 (use --opengl-es=yes --opengl-restrict=300)
|
|
- the --msg-level option now affects --log-file
|
|
- drop "audio-out-detected-device" property - this was unavailable on all
|
|
audio output drivers for quite a while (coreaudio used to provide it)
|
|
- deprecate --videotoolbox-format (use --hwdec-image-format, which affects
|
|
most other hwaccels)
|
|
- remove deprecated --demuxer-max-packets
|
|
- remove most of the deprecated audio and video filters
|
|
- remove the deprecated --balance option/property
|
|
- rename the --opengl-hwdec-interop option to --gpu-hwdec-interop, and
|
|
change some of its semantics: extend it take the strings "auto" and
|
|
"all". "all" loads all backends. "auto" behaves like "all" for
|
|
vo_opengl_cb, while on vo_gpu it loads nothing, but allows on demand
|
|
loading by the decoder. The empty string as option value behaves like
|
|
"auto". Old --hwdec values do not work anymore.
|
|
This option is hereby declared as unstable and may change any time - its
|
|
old use is deprecated, and it has very little use outside of debugging
|
|
now.
|
|
- change the --hwdec option from a choice to a plain string (affects
|
|
introspection of the option/property), also affects some properties
|
|
- rename --hwdec=rpi to --hwdec=mmal, same for the -copy variant (no
|
|
backwards compatibility)
|
|
- deprecate the --ff-aid, --ff-vid, --ff-sid options and properties (there is
|
|
no replacement, but you can manually query the track property and use the
|
|
"ff-index" field to find the mpv track ID to imitate this behavior)
|
|
- rename --no-ometadata to --no-ocopy-metadata
|
|
--- 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.
|
|
- --lavfi-complex can now be set during runtime. If you set this in
|
|
expectation it would be applied only after a reload, you might observe
|
|
weird behavior.
|
|
- add --track-auto-selection to help with scripts/applications that
|
|
make exclusive use of --lavfi-complex.
|
|
- undeprecate --loop, and map it from --loop-playlist to --loop-file (the
|
|
deprecation was to make sure no API user gets broken by a sudden behavior
|
|
change)
|
|
- remove previously deprecated vf_eq
|
|
- remove that hardware deinterlace filters (vavpp, d3d11vpp, vdpaupp)
|
|
changed their deinterlacing-enabled setting depending on what the
|
|
--deinterlace option or property was set to. Now, a filter always does
|
|
what its filter options and defaults imply. The --deinterlace option and
|
|
property strictly add/remove its own filters. For example, if you run
|
|
"mpv --vf=vavpp --deinterlace=yes", this will insert another, redundant
|
|
filter, which is probably not what you want. For toggling a deinterlace
|
|
filter manually, use the "vf toggle" command, and do not set the
|
|
deinterlace option/property. To customize the filter that will be
|
|
inserted automatically, use --vf-defaults. Details how this works will
|
|
probably change in the future.
|
|
- remove deinterlace=auto (this was not deprecated, but had only a very
|
|
obscure use that stopped working with the change above. It was also
|
|
prone to be confused with a feature not implemented by it: auto did _not_
|
|
mean that deinterlacing was enabled on demand.)
|
|
- add shortened mnemonic names for mouse button bindings, eg. mbtn_left
|
|
the old numeric names (mouse_btn0) are deprecated
|
|
- remove mouse_btn3_dbl and up, since they are only generated for buttons
|
|
0-2 (these now print an error when sent from the 'mouse' command)
|
|
- rename the axis bindings to wheel_up/down/etc. axis scrolling and mouse
|
|
wheel scrolling are now conceptually the same thing
|
|
the old axis_up/down names remain as deprecated aliases
|
|
--- 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 --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
|
|

|
- 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
|
