Many changes have been made, a +large part of which is incompatible or completely changes how the player +behaves. Although there are still many similarities to its ancestors, **mpv** +should generally be treated as a completely different program. + +.. note:: + These lists are incomplete. + +General Changes for MPlayer to mpv +---------------------------------- + +* Switch to GPLv2+. (Technically speaking, MPlayer as a whole seems to be + GPLv2-only, while mplayer2 is GPLv3+ - see ``Copyright`` file for details.) +* Removal of the internal GUI, MEncoder, OSD menu, video kernel drivers for + Linux 2.4 (including VIDIX) +* Large internal cleanups +* Removal of support for dead platforms +* New buildsystem +* No embedded copy of ffmpeg and other libraries +* Better pause handling (do not unpause on a command) +* Better MKV support (such as ordered chapters) +* vo_vdpau improvements +* Precise seeking support +* Native OpenGL backend for OSX +* General OSX improvements +* Improvements in audio/video sync handling +* Cleaned up terminal output +* Gapless audio support (``--gapless-audio``) +* Improved responsiveness on user input +* Support for modifier keys (alt, shift, ctrl) in input.conf +* OSS4 volume control +* More correct color reproduction (color matrix generation) +* Use libass for subtitle rendering by default (better quality) +* Generally preferring ffmpeg/libav over internal demuxers and decoders +* Improvements when playing multiple files (``--fixed-vo``) +* Screenshot improvements (instant screenshots without 1-frame delay, allow + taking screenshots even with hardware decoding) +* Improved support for PulseAudio +* Generally improved MS Windows support (dealing with unicode filenames, + improved ``--vo=direct3d``, improved window handling) +* Better OSD rendering (using libass). This has full unicode support, and + languages like Arabic should be better supported. +* Cleaned up terminal output (nicer status line, less useless noise) +* Support for playing URLs of popular streaming sites directly + (e.g. ``mpv https://www.youtube.com/watch?v=...``) +* Improved OpenGL output (``--vo=opengl-hq``) +* Make ``--softvol`` default (**mpv** is not a mixer control panel) +* Improved support for .cue files +* Screenshot improvements (can save screenshots as JPG or PNG, configurable + filenames, support for taking screenshots with or without subtitles - the + ``screenshot`` video filter is not needed anymore, and should not be put + into the mpv config file) +* Removal of teletext support +* Removal of most builtin demuxers, using libavformat instead +* Removal of builtin network support, using libavformat instead (also, + support https via libavformat) +* Replace image VOs (``--vo=jpeg`` etc.) with ``--vo=image`` +* Do not lose settings when playing a new file in the same player instance +* New location for config files, new name for the binary. +* Slave mode compatibility broken (see below) +* Encoding functionality (replacement for mencoder, see ``DOCS/encoding.rst``) +* Remove ``--vo=gif89a``, ``--vo=md5sum``, ``--vo=yuv4mpeg``, as encoding can + handle these use cases. For yuv4mpeg, for example, use: + ``mpv input.mkv -o output.y4m --no-audio --oautofps --oneverdrop``. +* Image subtitles (DVDs etc.) are rendered in color and use more correct + positioning (color can be disabled with ``--sub-gray``) +* Wayland support +* Support for precise scrolling which scales the parameter of commands. If the + input doesn't support precise scrolling the scale factor stays 1. +* OSX: Cocoa event loop is independent from mplayer's event loop, so user + actions like accessing menus and live resizing do not block the playback. +* OSX: Apple Remote support. +* OSX: Media Keys support. +* Windows: Added WASAPI audio output. +* New OSD bar with chapter marks and not positioned in the middle of the video + (though this can be customized with the ``--osd-bar-align-y`` option). +* Allow customizing whether a key binding for seeking shows the video time, the + OSD bar, or nothing (see section `Input Command Prefixes`_). +* Display list of chapters and audio/subtitle tracks on OSD (see section + `Properties`_). +* ``--keep-open`` option to stop the player from closing the window and + exiting after playback ends. +* Re-enable screensaver while the player is paused. +* Matroska edition switching at runtime. +* Support for libavfilter (for video->video and audio->audio). This allows + using most of FFmpeg's filters, which improve greatly on the old MPlayer + filters in features, performance, and correctness. +* Improved downmixing and output of surround audio. Instead of using hardcoded + pan filters to do remixing, use libavresample. Channel maps are used to + identify the channel layout, so e.g. ``3.0`` and ``2.1`` audio can be + distinguished. +* Allow resuming playback at a later point with ``Shift+q``, also see + ``quit_watch_later`` input command. +* Support mapping multiple commands to one key. +* Allow changing/adjusting video filters at runtime. (This is also used to make + the ``D`` key insert vf_yadif if deinterlacing is not supported otherwise.) +* Native VAAPI support +* OSX: VDA support using libavcodec hwaccel API insted of FFmpeg's decoder. Up + to 2-2.5x reduction in CPU usage. +* Make hardware decoding in general work with the ``opengl`` video output. +* Lua scripting (see `LUA SCRIPTING`_) +* A client API, that allows embedding **mpv** into applications + (see ``libmpv/client.h`` in the sources) +* General bug fixes and removal of long-standing issues +* General code cleanups (including refactoring or rewrites of many parts) +* Many more changes + +Detailed Listing of User-visible Changes +---------------------------------------- + +This listing is about changed command line switches, slave commands, and similar +things. Completely removed features are not listed. + +Command Line Switches +~~~~~~~~~~~~~~~~~~~~~ + +* There is a new command line syntax, which is generally preferred over the old + syntax. ``-optname optvalue`` becomes ``--optname=optvalue``. + + The old syntax will not be removed. However, the new syntax is mentioned in + all documentation and so on, and unlike the old syntax is not ambiguous, + so it is a good thing to know about this change. +* In general, negating switches like ``-noopt`` now have to be written as + ``-no-opt`` or ``--no-opt``. +* Per-file options are not the default anymore. You can explicitly specify + file-local options. See ``Usage`` section. +* Many options have been renamed, removed or changed semantics. Some options + that are required for a good playback experience with MPlayer are now + superfluous or even worse than the defaults, so make sure to read the manual + before trying to use your existing configuration with **mpv**. +* Table of renamed/replaced switches: + + =========================== ======================================== + Old New + =========================== ======================================== + ``-no`` ``--no-`` (add a dash) + ``-a52drc level`` ``--ad-lavc-ac3drc=level`` + ``-ac spdifac3`` ``--ad=spdif:ac3`` (see ``--ad=help``) + ``-af volnorm`` ``--af=drc`` (renamed) + ``-afm hwac3`` ``--ad=spdif:ac3,spdif:dts`` + ``-ao alsa:device=hw=0.3`` ``--ao=alsa:device=[hw:0,3]`` + ``-aspect`` ``--video-aspect`` + ``-ass-bottom-margin`` ``--vf=sub=bottom:top`` + ``-ass`` ``--sub-ass`` + ``-audiofile-cache`` (removed; the main cache settings are used) + ``-audiofile`` ``--audio-file`` + ``-benchmark`` ``--untimed`` (no stats) + ``-capture`` ``--stream-capture=`` + ``-channels`` ``--audio-channels`` (changed semantics) + ``-cursor-autohide-delay`` ``--cursor-autohide`` + ``-delay`` ``--audio-delay`` + ``-dumpstream`` ``--stream-dump=`` + ``-dvdangle`` ``--dvd-angle`` + ``-endpos`` ``--length`` + ``-font`` ``--osd-font`` + ``-forcedsubsonly`` ``--sub-forced-only`` + ``-forceidx`` ``--index`` + ``-format`` ``--audio-format`` + ``-fsmode-dontuse`` (removed) + ``-fstype`` ``--x11-netwm`` (changed semantics) + ``-hardframedrop`` ``--framedrop=hard`` + ``-identify`` (removed; use TOOLS/mpv_identify.sh) + ``-idx`` ``--index`` + ``-lavdopts ...`` ``--vd-lavc-...`` + ``-lavfdopts`` ``--demuxer-lavf-...`` + ``-lircconf`` ``--input-lirc-conf`` + ``-loop 0`` ``--loop=inf`` + ``-mixer-channel`` AO suboptions (``alsa``, ``oss``) + ``-mixer`` AO suboptions (``alsa``, ``oss``) + ``-mouse-movements`` ``--input-cursor`` + ``-msgcolor`` ``--msg-color`` + ``-msglevel`` ``--msg-level`` (changed semantics) + ``-msgmodule`` ``--msg-module`` + ``-name`` ``--x11-name`` + ``-noar`` ``--no-input-appleremote`` + ``-noautosub`` ``--no-sub-auto`` + ``-noconsolecontrols`` ``--no-input-terminal`` + ``-nojoystick`` ``--no-input-joystick`` + ``-nosound`` ``--no-audio`` + ``-osdlevel`` ``--osd-level`` + ``-panscanrange`` ``--video-zoom``, ``--video-pan-x/y`` + ``-playing-msg`` ``--term-playing-msg`` + ``-pp ...`` ``'--vf=pp=[...]'`` + ``-pphelp`` ``--vf=pp:help`` + ``-rawaudio ...`` ``--demuxer-rawaudio-...`` + ``-rawvideo ...`` ``--demuxer-rawvideo-...`` + ``-spugauss`` ``--sub-gauss`` + ``-srate`` ``--audio-samplerate`` + ``-ss`` ``--start`` + ``-ssf `` ``--sws-...`` + ``-stop-xscreensaver`` ``--stop-screensaver`` + ``-sub-fuzziness`` ``--sub-auto`` + ``-sub`` ``--sub-file`` + ``-subcp`` ``--sub-codepage`` + ``-subdelay`` ``--sub-delay`` + ``-subfile`` ``--sub-file`` + ``-subfont-*`` ``--sub-text-*``, ``--osd-*`` + ``-subfont-text-scale`` ``--sub-scale`` + ``-subfont`` ``--sub-text-font`` + ``-subfps`` ``--sub-fps`` + ``-subpos`` ``--sub-pos`` + ``-sws`` ``--sws-scaler`` + ``-tvscan`` ``--tv-scan`` + ``-use-filename-title`` ``--title='${filename}'`` + ``-vc ffh264vdpau`` (etc.) ``--hwdec=vdpau`` + ``-vobsub`` ``--sub-file`` (pass the .idx file) + ``-x W``, ``-y H`` ``--geometry=WxH`` + ``--no-keepaspect`` + ``-xineramascreen`` ``--screen`` (different values) + ``-xy W`` ``--autofit=W`` + ``-zoom`` Inverse available as ``--video-unscaled`` + ``dvdnav://`` ``dvdnav://menu`` + ``dvd://1`` ``dvd://0`` (0-based offset) + =========================== ======================================== + +.. note:: + + ``-opt val`` becomes ``--opt=val``. + +.. note:: + + Quite some video filters, video outputs, audio filters, audio outputs, had + changes in their option parsing. These aren't mentioned in the table above. + + Also, some video and audio filters have been removed, and you have to use + libavfilter (using ``--vf=lavfi=[...]`` or ``--af=lavfi=[...]``) to get + them back. + +input.conf and Slave Commands +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +* Table of renamed input commands: + + This lists only commands that are not always gracefully handled by the + internal legacy translation layer. If an input.conf contains any legacy + commands, a warning will be printed when starting the player.

This can be improved + if testers are available. Otherwise, some of the TV code will be + removed at some point. + +Slave mode +~~~~~~~~~~ + +* Slave mode is broken. This mode is entirely insane in the ``old`` versions of + MPlayer. A proper slave mode application needed tons of code and hacks to get + it right. The main problem is that slave mode is a bad and incomplete + interface, and to get around that, applications parsed output messages + intended for users. It is hard to know which messages exactly are parsed by + slave mode applications. This makes it virtually impossible to improve + terminal output intended for users without possibly breaking something. + + This is absolutely insane, and **mpv** will not try to keep slave mode + compatible. If you are a developer of a slave mode application, contact us, + and a new and better protocol can be developed. + + ``--identify`` was already removed (``TOOLS/mpv_identify.sh`` is provided + instead), and ``--slave-broken`` might be removed in the future. + +* **mpv** also provides a client API, which can be used to embed the player + by loading it as shared library. (See ``libmpv/client.h`` in the sources.) + It might also be possible to implement a custom slave mode-like protocol + using Lua scripting. + +* A slave protocol is planned, but nothing has emerged yet. + +Policy for Removed Features +--------------------------- + +**mpv** is in active development. If something is in the way of more important +development (such as fixing bugs or implementing new features), we sometimes +remove features. Usually this happens only with old features that either seem +to be useless, or are not used by anyone. Often these are obscure, or +"inherited", or were marked experimental, but never received any particular +praise by any users. + +Sometimes, features are replaced by something new. The new code will be either +simpler or more powerful, but doesn't necessarily provide everything the old +feature did. + +We can not exclude that we accidentally remove features that are actually +popular. Generally, we do not know how much a specific functionality is used. +If you miss a feature and think it should be re-added, please open an issue +on the mpv bug tracker. Hopefully, a solution can be found. Often, it turns +out that re-adding something is not much of a problem, or that there are +better alternatives. + +Why this Fork? +-------------- + +mplayer2 is practically dead, and mpv started out as a branch containing +new/experimental development. (Some of it was merged right *after* the fork +was made public, seemingly as an acknowledgment that development, or at +least merging, should have been more active.) + +MPlayer is focused on not breaking anything, but is stuck with a horrible +codebase resistant to cleanup. (Unless you do what mpv did - merciless and +consequent pruning of bad, old code.) Cleanup and keeping broken things +conflict, so the kind of development mpv strives for can't be done within +MPlayer due to clashing development policies. + +Additionally, mplayer2 already had lots of changes over MPlayer, which would +have needed to be backported to the MPlayer codebase. This would not only +have been hard (several years of diverging development), but also would have +been impossible due to the aforementioned MPlayer development policy. -- cgit v1.2.3
