Niklas Haas 586dc5574f vo_opengl: separate kernel and window
This makes the core much more elegant, reusable, reconfigurable and also
allows us to more easily add aliases for specific configurations.

Furthermore, this lets us apply a generic blur factor / window function
to arbitrary filters, so we can finally "mix and match" in order to
fine-tune windowing functions.

A few notes are in order:

1. The current system for configuring scalers is ugly and rapidly
   getting unwieldy. I modified the man page to make it a bit more
   bearable, but long-term we have to do something about it; especially
   since..

2. There's currently no way to affect the blur factor or parameters of
   the window functions themselves. For example, I can't actually
   fine-tune the kaiser window's param1, since there's simply no way to
   do so in the current API - even though filter_kernels.c supports it
   just fine!

3. This removes some lesser used filters (especially those which are
   purely window functions to begin with). If anybody asks, you can get
   eg. the old behavior of scale=hanning by using
   scale=box:scale-window=hanning:scale-radius=1 (and yes, the result is
   just as terrible as that sounds - which is why nobody should have
   been using them in the first place).

4. This changes the semantics of the "triangle" scaler slightly - it now
   has an arbitrary radius. This can possibly produce weird results for
   people who were previously using scale-down=triangle, especially if
   in combination with scale-radius (for the usual upscaling). The
   correct fix for this is to use scale-down=bilinear_slow instead,
   which is an alias for triangle at radius 1.

In regards to the last point, in future I want to make it so that
filters have a filter-specific "preferred radius" (for the ones that
are arbitrarily tunable), once the configuration system for filters has
been redesigned (in particular in a way that will let us separate scale
and scale-down cleanly). That way, "triangle" can simply have the
preferred radius of 1 by default, while still being tunable. (Rather
than the default radius being hard-coded to 3 always)

mpv

Overview

mpv is a media player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types.

Releases can be found on the release list.

Downloads

For semi-official builds and third-party packages please see mpv.io.

Compilation

Compiling with full features requires development files for several external libraries. Below is a list of some important requirements.

The mpv build system uses waf but we don't store it in your source tree. The script './bootstrap.py' will download the latest version of waf that was tested with the build system.

For a list of the available build options use ./waf configure --help. If you think you have support for some feature installed but configure fails to detect it, the file build/config.log may contain information about the reasons for the failure.

NOTE: To avoid cluttering the output with unreadable spam, --help only shows one of the two switches for each option. If the option is autodetected by default, the --disable-*** switch is printed; if the option is disabled by default, the --enable-*** switch is printed. Either way, you can use --enable-*** or --disable-** regardless of what is printed by --help.

To build the software you can use ./waf build: the result of the compilation will be located in build/mpv. You can use ./waf install to install mpv to the prefix after it is compiled.

NOTE: Using the old build system (with ./old-configure) should still work, but will be removed in a future version of mpv.

Essential dependencies (incomplete list):

  • gcc or clang
  • X development headers (xlib, X extensions, libvdpau, libGL, libXv, ...)
  • Audio output development headers (libasound/ALSA, pulseaudio)
  • FFmpeg libraries (libavutil libavcodec libavformat libswscale libavfilter and either libswresample or libavresample) At least FFmpeg 2.4.0 or Libav 11 is required.
  • zlib
  • iconv (normally provided by the system libc)
  • libass (OSD, OSC, text subtitles)
  • Lua (optional, required for the OSC pseudo-GUI and youtube-dl integration)
  • libjpeg (optional, used for screenshots only)
  • Enca (optional, for subtitle charset detection)
  • vdpau and vaapi libraries for hardware decoding on Linux (optional)

Libass dependencies:

  • gcc or clang, yasm on x86 and x86_64
  • fribidi, freetype, fontconfig development headers (for libass)
  • harfbuzz (optional, required for correct rendering of combining characters, particularly for correct rendering of non-English text on OSX, and Arabic/Indic scripts on any platform)

FFmpeg dependencies:

  • gcc or clang, yasm on x86 and x86_64
  • OpenSSL (has to be explicitly enabled when compiling ffmpeg)
  • libx264/libmp3lame/libfdk-aac if you want to use encoding (has to be explicitly enabled when compiling ffmpeg)
  • Libav also works, but some features will not work. (See section below.)

Most of the above libraries are available in suitable versions on normal Linux distributions. However FFmpeg is an exception (distro versions may be too old to work at all or work well). For that reason you may want to use the separately available build wrapper (mpv-build) that first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those.

If you are running Mac OSX and using homebrew we provide homebrew-mpv, an up to date formula that compiles mpv with sensible dependencies and defaults for OSX.

If you want to build a Windows binary, you either have to use MSYS2 and MinGW, or cross-compile from Linux with MinGW. See Windows compilation.

FFmpeg vs. Libav

Generally, mpv should work with the latest release as well as the git version of both FFmpeg and Libav. But FFmpeg is preferred, and some mpv features work with FFmpeg only. See the wiki article about the issue.

Release cycle

Every few months, a new release is cut off of the master branch and is assigned a 0.X.0 version number.

As part of the maintenance process, minor releases are made, which are assigned 0.X.Y version numbers. Minor releases contain bug fixes only. They never merge the master branch, and no features are added to it. Only the latest release is maintained.

The goal of releases is to provide stability and an unchanged base for the sake of Linux distributions. If you want the newest features, just use the master branch, which is stable most of the time, except sometimes, when it's not.

Releases other than the latest release are unsupported and unmaintained.

See the release policy document for more information.

Bug reports

Contributing

For small changes you can just send us pull requests through GitHub. For bigger changes come and talk to us on IRC before you start working on them. It will make code review easier for both parties later on.

Relation to MPlayer and mplayer2

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.

mpv was forked because we wanted to modernize MPlayer. This includes removing cruft (including features which stopped making sense 10 years ago), and of course adding modern features. Such huge and intrusive changes made it infeasible to work directly with MPlayer, which is mostly focused on preservation, so a fork had to be made. (Actually, mpv is based on mplayer2, which already started this process of removing cruft.)

In general, mpv should be considered a completely new program, rather than a MPlayer drop-in replacement.

If you are wondering what's different from mplayer2 and MPlayer, an incomplete list of changes is located here.
