## Overview
|
|
|
|
|
|
**mpv** is a free (as in freedom) media player for the command line. It supports
|
|
a wide variety of media file formats, audio and video codecs, and subtitle types.
|
|
|
|
There is a [FAQ][FAQ].
|
|
|
|
Releases can be found on the [release list][releases].
|
|
|
|
## System requirements
|
|
|
|
- A not too ancient Linux (usually, only the latest releases of distributions
|
|
are actively supported), Windows 10 1607 or later, or macOS 10.15 or later.
|
|
- A somewhat capable CPU. Hardware decoding might help if the CPU is too slow to
|
|
decode video in realtime, but must be explicitly enabled with the `--hwdec`
|
|
option.
|
|
- A not too crappy GPU. mpv's focus is not on power-efficient playback on
|
|
embedded or integrated GPUs (for example, hardware decoding is not even
|
|
enabled by default). Low power GPUs may cause issues like tearing, stutter,
|
|
etc. On such GPUs, it's recommended to use `--profile=fast` for smooth playback.
|
|
The main video output uses shaders for video rendering and scaling,
|
|
rather than GPU fixed function hardware. On Windows, you might want to make
|
|
sure the graphics drivers are current. In some cases, ancient fallback video
|
|
output methods can help (such as `--vo=xv` on Linux), but this use is not
|
|
recommended or supported.
|
|
|
|
mpv does not go out of its way to break on older hardware or old, unsupported
|
|
operating systems, but development is not done with them in mind. Keeping
|
|
compatibility with such setups is not guaranteed. If things work, consider it
|
|
a happy accident.
|
|

## Changelog
|
|
|
|
|
|
There is no complete changelog; however, changes to the player core interface
|
|
are listed in the [interface changelog][interface-changes].
|
|
|
|
Changes to the C API are documented in the [client API changelog][api-changes].
|
|
|
|
The [release list][releases] has a summary of most of the important changes
|
|
on every release.
|
|
|
|
Changes to the default key bindings are indicated in
|
|
[restore-old-bindings.conf][restore-old-bindings].
|
|
|
|
## Compilation
|
|
|
|
|
|
Compiling with full features requires development files for several
|
|
external libraries. Mpv requires [meson](https://mesonbuild.com/index.html)
|
|
to build. Meson can be obtained from your distro or PyPI.
|
|
|
|
After creating your build directory (e.g. `meson setup build`), you can view a list
|
|
of all the build options via `meson configure build`. You could also just simply
|
|
look at the `meson_options.txt` file. Logs are stored in `meson-logs` within
|
|
your build directory.
|
|
|
|
Example:
|
|
|
|
meson setup build
|
|
meson compile -C build
|
|
meson install -C build
|
|
|
|
For libplacebo, meson can use a git check out as a subproject for a convenient
|
|
way to compile mpv if a sufficient libplacebo version is not easily available
|
|
in the build environment. It will be statically linked with mpv. Example:
|
|
|
|
mkdir -p subprojects
|
|
git clone https://code.videolan.org/videolan/libplacebo.git --depth=1 --recursive subprojects/libplacebo
|
|
|
|
Essential dependencies (incomplete list):
|
|
|
|
- gcc or clang
|
|
- X development headers (xlib, xrandr, xext, xscrnsaver, xpresent, libvdpau,
|
|
libGL, GLX, EGL, xv, ...)
|
|
- Audio output development headers (libasound/ALSA, pulseaudio)
|
|
- FFmpeg libraries (libavutil libavcodec libavformat libswscale libavfilter
|
|
and either libswresample or libavresample)
|
|
- libplacebo
|
|
- 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)
|
|
- uchardet (optional, for subtitle charset detection)
|
|
- nvdec and vaapi libraries for hardware decoding on Linux (optional)
|
|
|
|
Libass dependencies (when building libass):
|
|
|
|
- gcc or clang, nasm on x86 and x86_64
|
|
- fribidi, freetype, fontconfig development headers (for libass)
|
|
- harfbuzz (required for correct rendering of combining characters, particularly
|
|
for correct rendering of non-English text on macOS, and Arabic/Indic scripts on
|
|
any platform)
|
|
|
|
FFmpeg dependencies (when building FFmpeg):
|
|
|
|
- gcc or clang, nasm on x86 and x86_64
|
|
- OpenSSL or GnuTLS (have to be explicitly enabled when compiling FFmpeg)
|
|
- libx264/libmp3lame/libfdk-aac if you want to use encoding (have to be
|
|
explicitly enabled when compiling FFmpeg)
|
|
- For native DASH playback, FFmpeg needs to be built with --enable-libxml2
|
|
(although there are security implications, and DASH support has lots of bugs).
|
|
- AV1 decoding support requires dav1d.
|
|
- For good nvidia support on Linux, make sure nv-codec-headers is installed
|
|
and can be found by configure.
|
|
|
|
Most of the above libraries are available in suitable versions on normal
|
|
Linux distributions. For ease of compiling the latest git master of everything,
|
|
you may wish to use the separately available build wrapper ([mpv-build][mpv-build])
|
|
which first compiles FFmpeg libraries and libass, and then compiles the player
|
|
statically linked against those.
|
|
|
|
If you want to build a Windows binary, see [Windows compilation][windows_compilation].
|
|
|
|
|
|
## Release cycle
|
|
|
|
Once or twice a year, a release is cut off from the current development state
|
|
and is assigned a 0.X.0 version number. No further maintenance is done, except
|
|
in the event of security issues.
|
|
|
|
The goal of releases is to make Linux distributions happy. Linux distributions
|
|
are also expected to apply their own patches in case of bugs.
|
|
|
|
Releases other than the latest release are unsupported and unmaintained.
|
|
|
|
See the [release policy document][release-policy] for more information.

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.

|
|
This software is based on the MPlayer project. Before mpv existed as a project,
|
