Make more aspects of the OSD font customizable. This also affects the font used for unstyled subtitles (such as SRT), or when using the --no-ass option. This adds back some customizability that was lost with commit 74e7a1 (osd: use libass for OSD rendering). Removed options: --ass-border-color --ass-color --font --subfont --subfont-text-scale Added options: --osd-color --osd-border --osd-back-color --osd-shadow-color --osd-font --osd-font-size --osd-border-size --osd-margin-x --osd-margin-y --osd-shadow-offset --osd-spacing --sub-scale The font size is now specified in pixels as it would be rendered on a window with a height of 720 pixels. OSD and subtitles are always scaled with the window height, so specifying or expecting an absolute font size doesn't make sense. Such scaled pixel units are used to specify font border etc. as well. (Note: the font size is directly passed to libass. How the fonts are actually rasterized is outside of our control, but in theory ASS font sizes map to "script" pixels and then are scaled to screen size.) The default settings should be about the same, with slight difference due to rounding to the new scales. The OSD and subtitle fonts are not separately configurable. It has limited use and would double the number of newly added options, which would be more confusing than helpful. It could be easily added later, should the need arise. Other small details that change: - ASS_Style.Encoding is not set to -1 for subs anymore (assuming subs use VSFilter direction in -no-ass mode too) - use a different WrapStyle for OSD - ASS forced styles are not applied to OSD

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. Some changes are incompatible, or completely change how the
|
|
player behaves.
|
|
|
|
General changes for mplayer-svn to mplayer2
|
|
-------------------------------------------
|
|
|
|
* Removal of the internal GUI, MEncoder, OSD menu
|
|
* Better pause handling (don't unpause on a command)
|
|
* Better MKV support (such as ordered chapters)
|
|
* vo_vdpau improvements
|
|
* Precise seeking support
|
|
* No embedded copy of ffmpeg and other libraries
|
|
* 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)
|
|
* Improved support for PulseAudio
|
|
* General code cleanups
|
|
* Many more changes
|
|
|
|
General changes for mplayer2 to mpv
|
|
----------------------------------------
|
|
|
|
* Removal of lots of unneeded code to encourage developer activity (less
|
|
obscure scary zombie code that kills any desire for hacking the codebase)
|
|
* Removal of dust and dead bodies (code-wise), such as kernel drivers for
|
|
decades old hardware
|
|
* Removal of support for dead platforms
|
|
* 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)
|
|
* Removal of teletext support
|
|
* 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``.
|
|
* Image subtitles (DVDs etc.) are rendered in color and use more correct
|
|
positioning
|
|
* General code cleanups
|
|
* 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 in the near future. However, the new
|
|
syntax is mentioned in all documentation and so on, so it's a good thing to
|
|
know about this change.
|
|
|
|
(The new syntax was introduced in mplayer2.)
|
|
* In general, negating switches like ``-noopt`` now have to be written as
|
|
``-no-opt``, or better ``--no-opt``.
|
|
* Per-file options are not the default anymore. You can explicitly specify
|
|
file local options. See ``Usage`` section.
|
|
* Table of renamed/replaced switches:

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, they will be displayed with ``-v`` when it is loaded, and show
|
|
and the replacement commands.
|
|
|
|
Properties containing ``_`` to separate words use ``-`` instead.

Other
|
|
~~~~~
|
|
|
|
* The playtree has been removed. **mpv**'s internal playlist is a simple and
|
|
flat list now. This makes the code easier, and makes **mpv** usage less
|
|
confusing.
|
|
* 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's 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're a developer of a slave mode application, contact us,
|
|
and a new and better protocol can be developed.
|
|
|
|
Policy for removed features
|
|
---------------------------
|
|
|
|
Features are a good thing, because they make users happy. As such, it is
|
|
attempted to preserve useful features as far as possible. But if a feature is
|
|
likely to be not used by many, and causes problems otherwise, it will be
|
|
removed. Developers should not be burdened with fixing or cleaning up code that
|
|
has no actual use.
|
|
|
|
It's always possible to add back removed features. File a feature request if a
|
|
feature you relied on was removed, and you want it back. Though it might be
|
|
rejected in the worst case, it's much more likely that it will be either added
|
|
back, or that a better solution will be implemented.
|
|
|
|
Why this fork?
|
|
--------------
|
|
|
|
* mplayer-svn wants to maintain old code, even if it's very bad code. It seems
|
|
mplayer2 was forked, because mplayer-svn developers refused to get rid of
|
|
all the cruft. The mplayer2 and mplayer-svn codebases also deviated enough to
|
|
make a reunification unlikely.
|
|
* mplayer2 development is slow, and it's hard to get in changes. Details
|
|
withheld as to not turn this into a rant.
|
|
* mplayer-svn rarely merged from mplayer2, and mplayer2 practically stopped
|
|
merging from mplayer-svn (not even code cleanups or new features are merged)
|
|
* **mpv** intents to continuously merge from mplayer-svn and mplayer2, while
|
|
speeding up development. There is willingness for significant changes, even
|
|
if this means breaking compatibility.
