VIDEO OUTPUT DRIVERS
|
|
====================
|
|
|
|
Video output drivers are interfaces to different video output facilities. The
|
|
syntax is:
|
|
|
|
``--vo=<driver1,driver2,...[,]>``
|
|
Specify a priority list of video output drivers to be used.
|
|
|
|
If the list has a trailing ``,``, mpv will fall back on drivers not contained
|
|
in the list.
|
|
|
|
``--vo-defaults=<driver1[:parameter1:parameter2:...],driver2,...>``
|
|
Set defaults for each driver.
|
|
|
|
Deprecated. No replacement.
|
|
|
|
.. note::
|
|
|
|
See ``--vo=help`` for a list of compiled-in video output drivers.
|
|
|
|
The recommended output driver is ``--vo=opengl``, which is the default. All
|
|
other drivers are for compatibility or special purposes. If the default
|
|
does not work, it will fallback to other drivers (in the same order as
|
|
listed by ``--vo=help``).
|
|
|
|
Available video output drivers are:
|
|
|
|
``xv`` (X11 only)
|
|
Uses the XVideo extension to enable hardware-accelerated display. This is
|
|
the most compatible VO on X, but may be low-quality, and has issues with
|
|
OSD and subtitle display.
|
|
|
|
.. note:: This driver is for compatibility with old systems.
|
|
|
|
The following global options are supported by this video output:
|
|
|
|
``--xv-adaptor=<number>``
|
|
Select a specific XVideo adapter (check xvinfo results).
|
|
``--xv-port=<number>``
|
|
Select a specific XVideo port.
|
|
``--xv-ck=<cur|use|set>``
|
|
Select the source from which the color key is taken (default: cur).
|
|
|
|
cur
|
|
The default takes the color key currently set in Xv.
|
|
use
|
|
Use but do not set the color key from mpv (use the ``--colorkey``
|
|
option to change it).
|
|
set
|
|
Same as use but also sets the supplied color key.
|
|
|
|
``--xv-ck-method=<none|man|bg|auto>``
|
|
Sets the color key drawing method (default: man).
|
|
|
|
none
|
|
Disables color-keying.
|
|
man
|
|
Draw the color key manually (reduces flicker in some cases).
|
|
bg
|
|
Set the color key as window background.
|
|
auto
|
|
Let Xv draw the color key.
|
|
|
|
``--xv-colorkey=<number>``
|
|
Changes the color key to an RGB value of your choice. ``0x000000`` is
|
|
black and ``0xffffff`` is white.
|
|
|
|
``--xv-buffers=<number>``
|
|
Number of image buffers to use for the internal ringbuffer (default: 2).
|
|
Increasing this will use more memory, but might help with the X server
|
|
not responding quickly enough if video FPS is close to or higher than
|
|
the display refresh rate.
|
|
|
|
``x11`` (X11 only)
|
|
Shared memory video output driver without hardware acceleration that works
|
|
whenever X11 is present.
|
|
|
|
.. note:: This is a fallback only, and should not be normally used.
|
|
|
|
``vdpau`` (X11 only)
|
|
Uses the VDPAU interface to display and optionally also decode video.
|
|
Hardware decoding is used with ``--hwdec=vdpau``.
|
|
|
|
.. note::
|
|
|
|
Earlier versions of mpv (and MPlayer, mplayer2) provided sub-options
|
|
to tune vdpau post-processing, like ``deint``, ``sharpen``, ``denoise``,
|
|
``chroma-deint``, ``pullup``, ``hqscaling``. These sub-options are
|
|
deprecated, and you should use the ``vdpaupp`` video filter instead.
|
|
|
|
The following global options are supported by this video output:
|
|
|
|
``--vo-vdpau-sharpen=<-1-1>``
|
|
(Deprecated. See note about ``vdpaupp``.)
|
|
|
|
For positive values, apply a sharpening algorithm to the video, for
|
|
negative values a blurring algorithm (default: 0).
|
|
``--vo-vdpau-denoise=<0-1>``
|
|
(Deprecated. See note about ``vdpaupp``.)
|
|
|
|
Apply a noise reduction algorithm to the video (default: 0; no noise
|
|
reduction).
|
|
``--vo-vdpau-deint=<-4-4>``
|
|
(Deprecated. See note about ``vdpaupp``.)
|
|
|
|
Select deinterlacing mode (default: 0). In older versions (as well as
|
|
MPlayer/mplayer2) you could use this option to enable deinterlacing.
|
|
This doesn't work anymore, and deinterlacing is enabled with either
|
|
the ``d`` key (by default mapped to the command ``cycle deinterlace``),
|
|
or the ``--deinterlace`` option. Also, to select the default deint mode,
|
|
you should use something like ``--vf-defaults=vdpaupp:deint-mode=temporal``
|
|
instead of this sub-option.
|
|
|
|
0
|
|
Pick the ``vdpaupp`` video filter default, which corresponds to 3.
|
|
1
|
|
Show only first field.
|
|
2
|
|
Bob deinterlacing.
|
|
3
|
|
Motion-adaptive temporal deinterlacing. May lead to A/V desync
|
|
with slow video hardware and/or high resolution.
|
|
4
|
|
Motion-adaptive temporal deinterlacing with edge-guided spatial
|
|
interpolation. Needs fast video hardware.
|
|
``--vo-vdpau-chroma-deint``
|
|
(Deprecated. See note about ``vdpaupp``.)
|
|
|
|
Makes temporal deinterlacers operate both on luma and chroma (default).
|
|
Use no-chroma-deint to solely use luma and speed up advanced
|
|
deinterlacing. Useful with slow video memory.
|
|
``--vo-vdpau-pullup``
|
|
(Deprecated. See note about ``vdpaupp``.)
|
|
|
|
Try to apply inverse telecine, needs motion adaptive temporal
|
|
deinterlacing.
|
|
``--vo-vdpau-hqscaling=<0-9>``
|
|
(Deprecated. See note about ``vdpaupp``.)
|
|
|
|
0
|
|
Use default VDPAU scaling (default).
|
|
1-9
|
|
Apply high quality VDPAU scaling (needs capable hardware).
|
|
``--vo-vdpau-fps=<number>``
|
|
Override autodetected display refresh rate value (the value is needed
|
|
for framedrop to allow video playback rates higher than display
|
|
refresh rate, and for vsync-aware frame timing adjustments). Default 0
|
|
means use autodetected value. A positive value is interpreted as a
|
|
refresh rate in Hz and overrides the autodetected value. A negative
|
|
value disables all timing adjustment and framedrop logic.
|
|
``--vo-vdpau-composite-detect``
|
|
NVIDIA's current VDPAU implementation behaves somewhat differently
|
|
under a compositing window manager and does not give accurate frame
|
|
timing information. With this option enabled, the player tries to
|
|
detect whether a compositing window manager is active. If one is
|
|
detected, the player disables timing adjustments as if the user had
|
|
specified ``fps=-1`` (as they would be based on incorrect input). This
|
|
means timing is somewhat less accurate than without compositing, but
|
|
with the composited mode behavior of the NVIDIA driver, there is no
|
|
hard playback speed limit even without the disabled logic. Enabled by
|
|
default, use ``no-composite-detect`` to disable.
|
|
``--vo-vdpau-queuetime-windowed=<number>`` and ``queuetime-fs=<number>``
|
|
Use VDPAU's presentation queue functionality to queue future video
|
|
frame changes at most this many milliseconds in advance (default: 50).
|
|
See below for additional information.
|
|
``--vo-vdpau-output-surfaces=<2-15>``
|
|
Allocate this many output surfaces to display video frames (default:
|
|
3). See below for additional information.
|
|
``--vo-vdpau-colorkey=<#RRGGBB|#AARRGGBB>``
|
|
Set the VDPAU presentation queue background color, which in practice
|
|
is the colorkey used if VDPAU operates in overlay mode (default:
|
|
``#020507``, some shade of black). If the alpha component of this value
|
|
is 0, the default VDPAU colorkey will be used instead (which is usually
|
|
green).
|
|
``--vo-vdpau-force-yuv``
|
|
Never accept RGBA input. This means mpv will insert a filter to convert
|
|
to a YUV format before the VO. Sometimes useful to force availability
|
|
of certain YUV-only features, like video equalizer or deinterlacing.
|
|
|
|
Using the VDPAU frame queuing functionality controlled by the queuetime
|
|
options makes mpv's frame flip timing less sensitive to system CPU load and
|
|
allows mpv to start decoding the next frame(s) slightly earlier, which can
|
|
reduce jitter caused by individual slow-to-decode frames. However, the
|
|
NVIDIA graphics drivers can make other window behavior such as window moves
|
|
choppy if VDPAU is using the blit queue (mainly happens if you have the
|
|
composite extension enabled) and this feature is active. If this happens on
|
|
your system and it bothers you then you can set the queuetime value to 0 to
|
|
disable this feature. The settings to use in windowed and fullscreen mode
|
|
are separate because there should be no reason to disable this for
|
|
fullscreen mode (as the driver issue should not affect the video itself).
|
|
|
|
You can queue more frames ahead by increasing the queuetime values and the
|
|
``output_surfaces`` count (to ensure enough surfaces to buffer video for a
|
|
certain time ahead you need at least as many surfaces as the video has
|
|
frames during that time, plus two). This could help make video smoother in
|
|
some cases. The main downsides are increased video RAM requirements for
|
|
the surfaces and laggier display response to user commands (display
|
|
changes only become visible some time after they're queued). The graphics
|
|
driver implementation may also have limits on the length of maximum
|
|
queuing time or number of queued surfaces that work well or at all.
|
|
|
|
``direct3d`` (Windows only)
|
|
Video output driver that uses the Direct3D interface.
|
|
|
|
.. note:: This driver is for compatibility with systems that don't provide
|
|
proper OpenGL drivers, and where ANGLE does not perform well.
|
|
|
|
.. note:: Before to 0.21.0, ``direct3d_shaders`` and ``direct3d`` were
|
|
different, with ``direct3d`` not using shader by default. Now
|
|
both use shaders by default, and ``direct3d_shaders`` is a
|
|
deprecated alias. Use the ``--vo-direct3d-prefer-stretchrect``
|
|
or the ``--vo-direct3d-disable-shaders`` options to get the old
|
|
behavior of ``direct3d``.
|
|
|
|
The following global options are supported by this video output:
|
|
|
|
``--vo-direct3d-prefer-stretchrect``
|
|
Use ``IDirect3DDevice9::StretchRect`` over other methods if possible.
|
|
|
|
``--vo-direct3d-disable-stretchrect``
|
|
Never render the video using ``IDirect3DDevice9::StretchRect``.
|
|
|
|
``--vo-direct3d-disable-textures``
|
|
Never render the video using D3D texture rendering. Rendering with
|
|
textures + shader will still be allowed. Add ``disable-shaders`` to
|
|
completely disable video rendering with textures.
|
|
|
|
``--vo-direct3d-disable-shaders``
|
|
Never use shaders when rendering video.
|
|
|
|
``--vo-direct3d-only-8bit``
|
|
Never render YUV video with more than 8 bits per component.
|
|
Using this flag will force software conversion to 8-bit.
|
|
|
|
``--vo-direct3d-disable-texture-align``
|
|
Normally texture sizes are always aligned to 16. With this option
|
|
enabled, the video texture will always have exactly the same size as
|
|
the video itself.
|
|
|
|
|
|
Debug options. These might be incorrect, might be removed in the future,
|
|
might crash, might cause slow downs, etc. Contact the developers if you
|
|
actually need any of these for performance or proper operation.
|
|
|
|
``--vo-direct3d-force-power-of-2``
|
|
Always force textures to power of 2, even if the device reports
|
|
non-power-of-2 texture sizes as supported.
|
|
|
|
``--vo-direct3d-texture-memory=<mode>``
|
|
Only affects operation with shaders/texturing enabled, and (E)OSD.
|
|
Possible values:
|
|
|
|
``default`` (default)
|
|
Use ``D3DPOOL_DEFAULT``, with a ``D3DPOOL_SYSTEMMEM`` texture for
|
|
locking. If the driver supports ``D3DDEVCAPS_TEXTURESYSTEMMEMORY``,
|
|
``D3DPOOL_SYSTEMMEM`` is used directly.
|
|
|
|
``default-pool``
|
|
Use ``D3DPOOL_DEFAULT``. (Like ``default``, but never use a
|
|
shadow-texture.)
|
|
|
|
``default-pool-shadow``
|
|
Use ``D3DPOOL_DEFAULT``, with a ``D3DPOOL_SYSTEMMEM`` texture for
|
|
locking. (Like ``default``, but always force the shadow-texture.)
|
|
|
|
``managed``
|
|
Use ``D3DPOOL_MANAGED``.
|
|
|
|
``scratch``
|
|
Use ``D3DPOOL_SCRATCH``, with a ``D3DPOOL_SYSTEMMEM`` texture for
|
|
locking.
|
|
|
|
``--vo-direct3d-swap-discard``
|
|
Use ``D3DSWAPEFFECT_DISCARD``, which might be faster.
|
|
Might be slower too, as it must(?) clear every frame.
|
|
|
|
``--vo-direct3d-exact-backbuffer``
|
|
Always resize the backbuffer to window size.
|
|
|
|
``opengl``
|
|
OpenGL video output driver. It supports extended scaling methods, dithering
|
|
and color management.
|
|
|
|
See `OpenGL renderer options`_ for options specific to this VO.
|
|
|
|
By default, it tries to use fast and fail-safe settings. Use the
|
|
``opengl-hq`` profile to use this driver with defaults set to high
|
|
quality rendering. (This profile is also the replacement for
|
|
``--vo=opengl-hq``.) The profile can be applied with ``--profile=opengl-hq``
|
|
and its contents can be viewed with ``--show-profile=opengl-hq``.
|
|
|
|
Requires at least OpenGL 2.1.
|
|
|
|
Some features are available with OpenGL 3 capable graphics drivers only
|
|
(or if the necessary extensions are available).
|
|
|
|
OpenGL ES 2.0 and 3.0 are supported as well.
|
|
|
|
Hardware decoding over OpenGL-interop is supported to some degree. Note
|
|
that in this mode, some corner case might not be gracefully handled, and
|
|
color space conversion and chroma upsampling is generally in the hand of
|
|
the hardware decoder APIs.
|
|
|
|
``opengl`` makes use of FBOs by default. Sometimes you can achieve better
|
|
quality or performance by changing the ``--opengl-fbo-format`` option to
|
|
``rgb16f``, ``rgb32f`` or ``rgb``. Known problems include Mesa/Intel not
|
|
accepting ``rgb16``, Mesa sometimes not being compiled with float texture
|
|
support, and some OS X setups being very slow with ``rgb16`` but fast
|
|
with ``rgb32f``. If you have problems, you can also try enabling the
|
|
``--opengl-dumb-mode=yes`` option.
|
|
|
|
``sdl``
|
|
SDL 2.0+ Render video output driver, depending on system with or without
|
|
hardware acceleration. Should work on all platforms supported by SDL 2.0.
|
|
For tuning, refer to your copy of the file ``SDL_hints.h``.
|
|
|
|
.. note:: This driver is for compatibility with systems that don't provide
|
|
proper graphics drivers, or which support GLES only.
|
|
|
|
The following global options are supported by this video output:
|
|
|
|
``--sdl-sw``
|
|
Continue even if a software renderer is detected.
|
|
|
|
``--sdl-switch-mode``
|
|
Instruct SDL to switch the monitor video mode when going fullscreen.
|
|
|
|
``vaapi``
|
|
Intel VA API video output driver with support for hardware decoding. Note
|
|
that there is absolutely no reason to use this, other than wanting to use
|
|
hardware decoding to save power on laptops, or possibly preventing video
|
|
tearing with some setups.
|
|
|
|
.. note:: This driver is for compatibility with crappy systems. You can
|
|
use vaapi hardware decoding with ``--vo=opengl`` too.
|
|
|
|
The following global options are supported by this video output:
|
|
|
|
``--vo-vaapi-scaling=<algorithm>``
|
|
default
|
|
Driver default (mpv default as well).
|
|
fast
|
|
Fast, but low quality.
|
|
hq
|
|
Unspecified driver dependent high-quality scaling, slow.
|
|
nla
|
|
``non-linear anamorphic scaling``
|
|
|
|
``--vo-vaapi-deint-mode=<mode>``
|
|
Select deinterlacing algorithm. Note that by default deinterlacing is
|
|
initially always off, and needs to be enabled with the ``d`` key
|
|
(default key binding for ``cycle deinterlace``).
|
|
|
|
This option doesn't apply if libva supports video post processing (vpp).
|
|
In this case, the default for ``deint-mode`` is ``no``, and enabling
|
|
deinterlacing via user interaction using the methods mentioned above
|
|
actually inserts the ``vavpp`` video filter. If vpp is not actually
|
|
supported with the libva backend in use, you can use this option to
|
|
forcibly enable VO based deinterlacing.
|
|
|
|
no
|
|
Don't allow deinterlacing (default for newer libva).
|
|
first-field
|
|
Show only first field (going by ``--field-dominance``).
|
|
bob
|
|
bob deinterlacing (default for older libva).
|
|
|
|
``--vo-vaapi-scaled-osd=<yes|no>``
|
|
If enabled, then the OSD is rendered at video resolution and scaled to
|
|
display resolution. By default, this is disabled, and the OSD is
|
|
rendered at display resolution if the driver supports it.
|
|
|
|
``null``
|
|
Produces no video output. Useful for benchmarking.
|
|
|
|
Usually, it's better to disable video with ``--no-video`` instead.
|
|
|
|
The following global options are supported by this video output:
|
|
|
|
``--vo-null-fps=<value>``
|
|
Simulate display FPS. This artificially limits how many frames the
|
|
VO accepts per second.
|
|
|
|
``caca``
|
|
Color ASCII art video output driver that works on a text console.
|
|
|
|
.. note:: This driver is a joke.
|
|
|
|
``image``
|
|
Output each frame into an image file in the current directory. Each file
|
|
takes the frame number padded with leading zeros as name.
|
|
|
|
The following global options are supported by this video output:
|
|
|
|
``--vo-image-format=<format>``
|
|
Select the image file format.
|
|
|
|
jpg
|
|
JPEG files, extension .jpg. (Default.)
|
|
jpeg
|
|
JPEG files, extension .jpeg.
|
|
png
|
|
PNG files.
|
|
ppm
|
|
Portable bitmap format.
|
|
pgm
|
|
Portable graymap format.
|
|
pgmyuv
|
|
Portable graymap format, using the YV12 pixel format.
|
|
tga
|
|
Truevision TGA.
|
|
|
|
``--vo-image-png-compression=<0-9>``
|
|
PNG compression factor (speed vs. file size tradeoff) (default: 7)
|
|
``--vo-image-png-filter=<0-5>``
|
|
Filter applied prior to PNG compression (0 = none; 1 = sub; 2 = up;
|
|
3 = average; 4 = Paeth; 5 = mixed) (default: 5)
|
|
``--vo-image-jpeg-quality=<0-100>``
|
|
JPEG quality factor (default: 90)
|
|
``--vo-image-jpeg-progressive=<yes|no>``
|
|
Specify standard or progressive JPEG (default: no).
|
|
``--vo-image-jpeg-baseline=<yes|no>``
|
|
Specify use of JPEG baseline or not (default: yes).
|
|
``--vo-image-jpeg-optimize=<0-100>``
|
|
JPEG optimization factor (default: 100)
|
|
``--vo-image-jpeg-smooth=<0-100>``
|
|
smooth factor (default: 0)
|
|
``--vo-image-jpeg-dpi=<1->``
|
|
JPEG DPI (default: 72)
|
|
``--vo-image-outdir=<dirname>``
|
|
Specify the directory to save the image files to (default: ``./``).
|
|
|
|
``wayland`` (Wayland only)
|
|
Wayland shared memory video output as fallback for ``opengl``.
|
|
|
|
.. note:: This driver is for compatibility with systems that don't provide
|
|
working OpenGL drivers.
|
|
|
|
The following global options are supported by this video output:
|
|
|
|
``--vo-wayland-alpha``
|
|
Use a buffer format that supports videos and images with alpha
|
|
information
|
|
``--vo-wayland-rgb565``
|
|
Use RGB565 as buffer format. This format is implemented on most
|
|
platforms, especially on embedded where it is far more efficient then
|
|
RGB8888.
|
|
``--vo-wayland-triple-buffering``
|
|
Use 3 buffers instead of 2. This can lead to more fluid playback, but
|
|
uses more memory.
|
|
|
|
``opengl-cb``
|
|
For use with libmpv direct OpenGL embedding; useless in any other contexts.
|
|
(See ``<mpv/opengl_cb.h>``.)
|
|
|
|
This also supports many of the options the ``opengl`` VO has.
|
|
|
|
``rpi`` (Raspberry Pi)
|
|
Native video output on the Raspberry Pi using the MMAL API.
|
|
|
|
This is deprecated. Use ``--vo=opengl`` instead, which is the default and
|
|
provides the same functionality. The ``rpi`` VO will be removed in
|
|
mpv 0.22.0. Its functionality was folded into --vo=opengl, which now uses
|
|
RPI hardware decoding by treating it as a hardware overlay (without applying
|
|
GL filtering). Also to be changed in 0.22.0: the --fs flag will be reset to
|
|
"no" by default (like on the other platforms).
|
|
|
|
The following deprecated global options are supported by this video output:
|
|
|
|
``--rpi-display=<number>``
|
|
Select the display number on which the video overlay should be shown
|
|
(default: 0).
|
|
|
|
``--rpi-layer=<number>``
|
|
Select the dispmanx layer on which the video overlay should be shown
|
|
(default: -10). Note that mpv will also use the 2 layers above the
|
|
selected layer, to handle the window background and OSD. Actual video
|
|
rendering will happen on the layer above the selected layer.
|
|
|
|
``--rpi-background=<yes|no>``

Whether to render a black background behind the video (default: no).
|
|
Normally it's better to kill the console framebuffer instead, which
|
|
gives better performance.
|
|
|
|
``--rpi-osd=<yes|no>``
|
|
Enabled by default. If disabled with ``no``, no OSD layer is created.
|
|
This also means there will be no subtitles rendered.
|
|
|
|
``drm`` (Direct Rendering Manager)
|
|
Video output driver using Kernel Mode Setting / Direct Rendering Manager.
|
|
Should be used when one doesn't want to install full-blown graphical
|
|
environment (e.g. no X). Does not support hardware acceleration (if you
|
|
need this, check the ``drm-egl`` backend for ``opengl`` VO).
|
|
|
|
The following global options are supported by this video output:
|
|
|
|
``--drm-connector=<number>``
|
|
Select the connector to use (usually this is a monitor.) If set to -1,
|
|
mpv renders the output on the first available connector. (default: -1)
|
|
|
|
``--drm-devpath=<filename>``
|
|
Path to graphic card device.
|
|
(default: /dev/dri/card0)
|
|
|
|
``--drm-mode=<number>``
|
|
Mode ID to use (resolution, bit depth and frame rate).
|
|
(default: 0)
