Vulkan Video Decoding has finally become a reality, as it's now showing up in shipping drivers, and the ffmpeg support has been merged. With that in mind, this change introduces HW interop support for ffmpeg Vulkan frames. The implementation is functionally complete - it can display frames produced by hardware decoding, and it can work with ffmpeg vulkan filters. There are still various caveats due to gaps and bugs in drivers, so YMMV, as always. Primary testing has been done on Intel, AMD, and nvidia hardware on Linux with basic Windows testing on nvidia. Notable caveats: * Due to driver bugs, video decoding on nvidia does not work right now, unless you use the Vulkan Beta driver. It can be worked around, but requires ffmpeg changes that are not considered acceptable to merge. * Even if those work-arounds are applied, Vulkan filters will not work on video that was decoded by Vulkan, due to additional bugs in the nvidia drivers. The filters do work correctly on content decoded some other way, and then uploaded to Vulkan (eg: Decode with nvdec, upload with --vf=format=vulkan) * Vulkan filters can only be used with drivers that support VK_EXT_descriptor_buffer which doesn't include Intel ANV as yet. There is an MR outstanding for this. * When dealing with 1080p content, there may be some visual distortion in the bottom lines of frames due to chroma scaling incorporating the extra hidden lines at the bottom of the frame (1080p content is actually stored as 1088 lines), depending on the hardware/driver combination and the scaling algorithm. This cannot be easily addressed as the mechanical fix for it violates the Vulkan spec, and probably requires a spec change to resolve properly. All of these caveats will be fixed in either drivers or ffmpeg, and so will not require mpv changes (unless something unexpected happens) If you want to run on nvidia with the non-beta drivers, you can this ffmpeg tree with the work-around patches: * https://github.com/philipl/FFmpeg/tree/vulkan-nvidia-workarounds |

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.
Releases can be found on the release list.
System requirements
- A not too ancient Linux, Windows 7 or later, or OSX 10.8 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
--hwdecoption. - 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. 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=xvon Linux), but this use is not recommended or supported.
Downloads
For semi-official builds and third-party packages please see mpv.io/installation.
Changelog
There is no complete changelog; however, changes to the player core interface are listed in the interface changelog.
Changes to the C API are documented in the client API changelog.
The release list 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.
Compilation
Compiling with full features requires development files for several
external libraries. One of the two build systems supported by mpv is required:
meson or waf. Meson
can be obtained from your distro or PyPI. Waf can be downloaded by using the
./bootstrap.py script. It will get the latest version of waf that was tested
with mpv. Some documentation about the differences between the build systems are
located in build-system-differences.
Note: Building with waf is considered deprecated and will be removed in the future.
Meson
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
Waf
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 or
enabled 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.
Example:
./bootstrap.py
./waf configure
./waf
./waf install
Essential dependencies (incomplete list):
- gcc or clang
- X development headers (xlib, xrandr, xext, xscrnsaver, xinerama, libvdpau, libGL, GLX, EGL, xv, ...)
- Audio output development headers (libasound/ALSA, pulseaudio)
- FFmpeg libraries (libavutil libavcodec libavformat libswscale libavfilter and either libswresample or libavresample)
- 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, yasm 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 OSX, and Arabic/Indic scripts on any platform)
FFmpeg dependencies (when building FFmpeg):
- gcc or clang, yasm 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) which first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those.
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.
Release cycle
Every other month, an arbitrary git snapshot is made, and is assigned a 0.X.0 version number. No further maintenance is done.
The goal of releases is to make Linux distributions happy. Linux distributions are also expected to apply their own patches in case of bugs and security issues.
Releases other than the latest release are unsupported and unmaintained.
See the release policy document for more information.
Bug reports
Please use the issue tracker provided by GitHub to send us bug reports or feature requests. Follow the template's instructions or the issue will likely be ignored or closed as invalid.
Using the bug tracker as place for simple questions is fine but IRC is recommended (see Contact below).
Contributing
Please read contribute.md.
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.
You can check the wiki or the issue tracker for ideas on what you could contribute with.
License
GPLv2 "or later" by default, LGPLv2.1 "or later" with --enable-lgpl.
See details.
History
This software is based on the MPlayer project. Before mpv existed as a project, the code base was briefly developed under the mplayer2 project. For details, see the FAQ.
