CHANGES FROM OTHER VERSIONS OF MPLAYER
|
|
======================================
|
|
|
|
**mpv** is based on mplayer2, which in turn is based on the original MPlayer
|
|
(also called mplayer, mplayer-svn, mplayer1). 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**.

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. The warnings
|
|
also show the replacement commands.
|
|
|
|
Properties containing ``_`` to separate words use ``-`` instead.

|
|
|
|
.. note::
|
|
|
|
Due to lack of hardware and users using the TV/DVB/PVR features, and
|
|
due to the need to cleanup the related command code, it's possible
|
|
that the new commands are buggy or behave worse. 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.
|
