About a year ago, ubitux converted most of the old manpage from the
hard to maintain nroff format to reStructuredText. This was not merged
back into the master repository immediately. The argument was that the
new manpage still required work to be done. However, progress was very
slow. Even worse: the old manpage wasn't updated, because it was
scheduled for deletion, and updating it would have meant useless work.
Now the situation is that the new manpage still isn't finished, and the
old manpage is grossly out of sync with the player. This is not helpful
for users. Additionally, keeping the new manpage in a separate branch,
while the normal development repository for code had the old manpage,
was very inconvenient, because you couldn't just update the
documentation in the same commit as the code.
Even though the new manpage isn't finished yet, merging it now seems to
be the best course of action. Squash-merge the manpage development
branch [1], revision e89f5dd3f2, which branches from the mplayer2
master branch after revision 159102e0cb.
Committers:
* Clément Bœsch <ubitux@gmail.com> (Initial conversion to RST.)
* Uoti Urpala <uau@mplayer2.org> (Many updates.)
* Myself (Minor edits.)
Most text of the manpage has been directly taken from the old manpage,
because this is a conversion, not a complete rewrite.

VIDEO OUTPUT DRIVERS
|
|
====================
|
|
|
|
Video output drivers are interfaces to different video output facilities. The
|
|
syntax is:
|
|
|
|
--vo=<driver1[:suboption1[=value]:...],driver2,...[,]>
|
|
Specify a priority list of video output drivers to be used.
|
|
|
|
If the list has a trailing ',' MPlayer will fall back on drivers not contained
|
|
in the list. Suboptions are optional and can mostly be omitted.
|
|
|
|
*NOTE*: See ``--vo=help`` for a list of compiled-in video output drivers.
|
|
|
|
*EXAMPLE*:
|
|
|
|
``--vo=xmga,xv,``
|
|
Try the Matrox X11 driver, then the Xv driver, then others.
|
|
``--vo=directx:noaccel``
|
|
Uses the DirectX driver with acceleration features turned off.
|
|
|
|
Available video output drivers are:
|
|
|
|
xv (X11 only)
|
|
Uses the XVideo extension to enable hardware accelerated playback. If you
|
|
cannot use a hardware specific driver, this is probably the best option.
|
|
For information about what colorkey is used and how it is drawn run
|
|
MPlayer with ``-v`` option and look out for the lines tagged with ``[xv
|
|
common]`` at the beginning.
|
|
|
|
adaptor=<number>
|
|
Select a specific XVideo adaptor (check xvinfo results).
|
|
port=<number>
|
|
Select a specific XVideo port.
|
|
ck=<cur|use|set>
|
|
Select the source from which the colorkey is taken (default: cur).
|
|
|
|
cur
|
|
The default takes the colorkey currently set in Xv.
|
|
use
|
|
Use but do not set the colorkey from MPlayer (use the ``--colorkey``
|
|
option to change it).
|
|
set
|
|
Same as use but also sets the supplied colorkey.
|
|
|
|
ck-method=<man|bg|auto>
|
|
Sets the colorkey drawing method (default: man).
|
|
|
|
man
|
|
Draw the colorkey manually (reduces flicker in some cases).
|
|
bg
|
|
Set the colorkey as window background.
|
|
auto
|
|
Let Xv draw the colorkey.
|
|
|
|
x11 (X11 only)
|
|
Shared memory video output driver without hardware acceleration that works
|
|
whenever X11 is present.
|
|
|
|
xover (X11 only)
|
|
Adds X11 support to all overlay based video output drivers. Currently only
|
|
supported by tdfx_vid.
|
|
|
|
<vo_driver>
|
|
Select the driver to use as source to overlay on top of X11.
|
|
|
|
vdpau (X11 only)
|
|
Uses the VDPAU interface to display and optionally also decode video.
|
|
Hardware decoding is used with ``--vc=ffmpeg12vdpau``,
|
|
``--vc=ffwmv3vdpau``, ``--vc=ffvc1vdpau``, ``--vc=ffh264vdpau`` or
|
|
``--vc=ffodivxvdpau``.
|
|
|
|
sharpen=<-1-1>
|
|
For positive values, apply a sharpening algorithm to the video, for
|
|
negative values a blurring algorithm (default: 0).
|
|
denoise=<0-1>
|
|
Apply a noise reduction algorithm to the video (default: 0, no noise
|
|
reduction).
|
|
deint=<-4-4>
|
|
Select deinterlacing mode (default: -3). Positive values choose mode
|
|
and enable deinterlacing. Corresponding negative values select the
|
|
same deinterlacing mode, but do not enable deinterlacing on startup
|
|
(useful in configuration files to specify what mode will be enabled by
|
|
the "D" key). All modes respect ``--field-dominance``.
|
|
|
|
0
|
|
same as -3
|
|
1
|
|
Show only first field, similar to ``--vf=field``.
|
|
2
|
|
Bob deinterlacing, similar to ``--vf=tfields=1``.
|
|
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.
|
|
chroma-deint
|
|
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.
|
|
pullup
|
|
Try to apply inverse telecine, needs motion adaptive temporal
|
|
deinterlacing.
|
|
hqscaling=<0-9>
|
|
0
|
|
Use default VDPAU scaling (default).
|
|
1-9
|
|
Apply high quality VDPAU scaling (needs capable hardware).
|
|
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.
|
|
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.
|
|
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.
|
|
output_surfaces=<2-15>
|
|
Allocate this many output surfaces to display video frames (default:
|
|
3). See below for additional information.
|
|
|
|
Using the VDPAU frame queueing functionality controlled by the queuetime
|
|
options makes MPlayer's frame flip timing less sensitive to system CPU
|
|
load and allows MPlayer 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 less
|
|
reason to disable this for fullscreen mode (as the driver issue shouldn't
|
|
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.
|
|
|
|
dga (X11 only)
|
|
Play video through the XFree86 Direct Graphics Access extension.
|
|
Considered obsolete.
|
|
|
|
sdl (SDL only, buggy/outdated)
|
|
Highly platform independent SDL (Simple Directmedia Layer) library video
|
|
output driver. Since SDL uses its own X11 layer, MPlayer X11 options do
|
|
not have any effect on SDL. Note that it has several minor bugs
|
|
(``--vm``/``--no-vm`` is mostly ignored, ``--fs`` behaves like ``--no-vm``
|
|
should, window is in top-left corner when returning from fullscreen,
|
|
panscan is not supported, ...).
|
|
|
|
driver=<driver>
|
|
Explicitly choose the SDL driver to use.
|
|
(no-)forcexv
|
|
Use XVideo through the sdl video output driver (default: forcexv).
|
|
(no-)hwaccel
|
|
Use hardware accelerated scaler (default: hwaccel).
|
|
|
|
direct3d (Windows only) (BETA CODE!)
|
|
Video output driver that uses the Direct3D interface (useful for Vista).
|
|
|
|
directx (Windows only)
|
|
Video output driver that uses the DirectX interface.
|
|
|
|
noaccel
|
|
Turns off hardware acceleration. Try this option if you have display
|
|
problems.
|
|
|
|
corevideo (Mac OS X 10.4 or 10.3.9 with QuickTime 7)
|
|
Mac OS X CoreVideo video output driver
|
|
|
|
device_id=<number>
|
|
Choose the display device to use for fullscreen or set it to -1 to
|
|
always use the same screen the video window is on (default: -1 -
|
|
auto).
|
|
shared_buffer
|
|
Write output to a shared memory buffer instead of displaying it and
|
|
try to open an existing NSConnection for communication with a GUI.
|
|
buffer_name=<name>
|
|
Name of the shared buffer created with shm_open as well as the name of
|
|
the NSConnection MPlayer will try to open (default: "mplayerosx").
|
|
Setting buffer_name implicitly enables shared_buffer.
|
|
|
|
fbdev (Linux only)
|
|
Uses the kernel framebuffer to play video.
|
|
|
|
<device>
|
|
Explicitly choose the fbdev device name to use (e.g. ``/dev/fb0``).
|
|
|
|
fbdev2 (Linux only)
|
|
Uses the kernel framebuffer to play video, alternative implementation.
|
|
|
|
<device>
|
|
Explicitly choose the fbdev device name to use (default: ``/dev/fb0``).
|
|
|
|
vesa
|
|
Very general video output driver that should work on any VESA VBE 2.0
|
|
compatible card.
|
|
|
|
(no-)dga
|
|
Turns DGA mode on or off (default: on).
|
|
neotv_pal
|
|
Activate the NeoMagic TV out and set it to PAL norm.
|
|
neotv_ntsc
|
|
Activate the NeoMagic TV out and set it to NTSC norm.
|
|
lvo
|
|
Activate the Linux Video Overlay on top of VESA mode.
|
|
|
|
svga
|
|
Play video using the SVGA library.
|
|
|
|
<video mode>
|
|
Specify video mode to use. The mode can be given in a
|
|
<width>x<height>x<colors> format, e.g. 640x480x16M or be a graphics
|
|
mode number, e.g. 84.
|
|
bbosd
|
|
Draw OSD into black bands below the movie (slower).
|
|
native
|
|
Use only native drawing functions. This avoids direct rendering, OSD
|
|
and hardware acceleration.
|
|
retrace
|
|
Force frame switch on vertical retrace. Usable only with ``--double``.
|
|
It has the same effect as the ``--vsync`` option.
|
|
sq
|
|
Try to select a video mode with square pixels.
|
|
|
|
gl
|
|
OpenGL video output driver, simple version. Video size must be smaller
|
|
than the maximum texture size of your OpenGL implementation. Intended to
|
|
work even with the most basic OpenGL implementations, but also makes use
|
|
of newer extensions, which allow support for more colorspaces and direct
|
|
rendering. For optimal speed try adding the options ``--dr=-noslices``
|
|
|
|
The code performs very few checks, so if a feature does not work, this
|
|
might be because it is not supported by your card/OpenGL implementation
|
|
even if you do not get any error message. Use ``glxinfo`` or a similar
|
|
tool to display the supported OpenGL extensions.
|
|
|
|
(no-)ati-hack
|
|
ATI drivers may give a corrupted image when PBOs are used (when using
|
|
``--dr`` or `force-pbo`). This option fixes this, at the expense of
|
|
using a bit more memory.
|
|
(no-)force-pbo
|
|
Always uses PBOs to transfer textures even if this involves an extra
|
|
copy. Currently this gives a little extra speed with NVidia drivers
|
|
and a lot more speed with ATI drivers. May need ``--no-slices`` and
|
|
the ati-hack suboption to work correctly.
|
|
(no-)scaled-osd
|
|
Changes the way the OSD behaves when the size of the window changes
|
|
(default: disabled). When enabled behaves more like the other video
|
|
output drivers, which is better for fixed-size fonts. Disabled looks
|
|
much better with FreeType fonts and uses the borders in fullscreen
|
|
mode. Does not work correctly with ass subtitles (see ``--ass``), you
|
|
can instead render them without OpenGL support via ``--vf=ass``.
|
|
osdcolor=<0xAARRGGBB>
|
|
Color for OSD (default: 0x00ffffff, corresponds to non-transparent
|
|
white).
|
|
rectangle=<0,1,2>
|
|
Select usage of rectangular textures which saves video RAM, but often
|
|
is slower (default: 0).
|
|
|
|
0
|
|
Use power-of-two textures (default).
|
|
1
|
|
Use the ``GL_ARB_texture_rectangle`` extension.
|
|
2
|
|
Use the ``GL_ARB_texture_non_power_of_two`` extension. In some
|
|
cases only supported in software and thus very slow.
|
|
|
|
swapinterval=<n>
|
|
Minimum interval between two buffer swaps, counted in displayed frames
|
|
(default: 1). 1 is equivalent to enabling VSYNC, 0 to disabling VSYNC.
|
|
Values below 0 will leave it at the system default. This limits the
|
|
framerate to (horizontal refresh rate / n). Requires
|
|
``GLX_SGI_swap_control`` support to work. With some (most/all?)
|
|
implementations this only works in fullscreen mode.
|
|
ycbcr
|
|
Use the ``GL_MESA_ycbcr_texture`` extension to convert YUV to RGB. In
|
|
most cases this is probably slower than doing software conversion to
|
|
RGB.
|
|
yuv=<n>
|
|
Select the type of YUV to RGB conversion. The default is
|
|
auto-detection deciding between values 0 and 2.
|
|
|
|
0
|
|
Use software conversion. Compatible with all OpenGL versions.
|
|
Provides brightness, contrast and saturation control.
|
|
1
|
|
Same as 2. This used to use nVidia-specific extensions, which
|
|
didn't provide any advantages over using fragment programs, except
|
|
possibly on very ancient graphic cards. It produced a gray-ish
|
|
output, which is why it has been removed.
|
|
2
|
|
Use a fragment program. Needs the ``GL_ARB_fragment_program``
|
|
extension and at least three texture units. Provides brightness,
|
|
contrast, saturation and hue control.
|
|
3
|
|
Use a fragment program using the POW instruction. Needs the
|
|
``GL_ARB_fragment_program`` extension and at least three texture
|
|
units. Provides brightness, contrast, saturation, hue and gamma
|
|
control. Gamma can also be set independently for red, green and
|
|
blue. Method 4 is usually faster.
|
|
4
|
|
Use a fragment program with additional lookup. Needs the
|
|
``GL_ARB_fragment_program`` extension and at least four texture
|
|
units. Provides brightness, contrast, saturation, hue and gamma
|
|
control. Gamma can also be set independently for red, green and
|
|
blue.
|
|
5
|
|
Use ATI-specific method (for older cards). This uses an
|
|
ATI-specific extension (``GL_ATI_fragment_shader`` - not
|
|
``GL_ARB_fragment_shader``!). At least three texture units are
|
|
needed. Provides saturation and hue control. This method is fast
|
|
but inexact.
|
|
6
|
|
Use a 3D texture to do conversion via lookup. Needs the
|
|
``GL_ARB_fragment_program extension`` and at least four texture
|
|
units. Extremely slow (software emulation) on some (all?) ATI
|
|
cards since it uses a texture with border pixels. Provides
|
|
brightness, contrast, saturation, hue and gamma control. Gamma can
|
|
also be set independently for red, green and blue. Speed depends
|
|
more on GPU memory bandwidth than other methods.
|
|
|
|
lscale=<n>
|
|
Select the scaling function to use for luminance scaling. Only valid
|
|
for yuv modes 2, 3, 4 and 6.
|
|
|
|
0
|
|
Use simple linear filtering (default).
|
|
1
|
|
Use bicubic B-spline filtering (better quality). Needs one
|
|
additional texture unit. Older cards will not be able to handle
|
|
this for chroma at least in fullscreen mode.
|
|
2
|
|
Use cubic filtering in horizontal, linear filtering in vertical
|
|
direction. Works on a few more cards than method 1.
|
|
3
|
|
Same as 1 but does not use a lookup texture. Might be faster on
|
|
some cards.
|
|
4
|
|
Use experimental unsharp masking with 3x3 support and a default
|
|
strength of 0.5 (see `filter-strength`).
|
|
5
|
|
Use experimental unsharp masking with 5x5 support and a default
|
|
strength of 0.5 (see `filter-strength`).
|
|
|
|
cscale=<n>
|
|
Select the scaling function to use for chrominance scaling. For
|
|
details see `lscale`.
|
|
filter-strength=<value>
|
|
Set the effect strength for the `lscale`/`cscale` filters that support
|
|
it.
|
|
stereo=<value>
|
|
Select a method for stereo display. You may have to use ``--aspect`` to
|
|
fix the aspect value. Experimental, do not expect too much from it.
|
|
|
|
0
|
|
Normal 2D display
|
|
1
|
|
Convert side by side input to full-color red-cyan stereo.
|
|
2
|
|
Convert side by side input to full-color green-magenta stereo.
|
|
3
|
|
Convert side by side input to quadbuffered stereo. Only supported
|
|
by very few OpenGL cards.
|
|
|
|
The following options are only useful if writing your own fragment
|
|
programs.
|
|
|
|
customprog=<filename>
|
|
Load a custom fragment program from <filename>. See
|
|
``TOOLS/edgedect.fp`` for an example.
|
|
customtex=<filename>
|
|
Load a custom "gamma ramp" texture from <filename>. This can be used
|
|
in combination with yuv=4 or with the customprog option.
|
|
(no-)customtlin
|
|
If enabled (default) use ``GL_LINEAR`` interpolation, otherwise use
|
|
``GL_NEAREST`` for customtex texture.
|
|
(no-)customtrect
|
|
If enabled, use texture_rectangle for customtex texture. Default is
|
|
disabled.
|
|
(no-)mipmapgen
|
|
If enabled, mipmaps for the video are automatically generated. This
|
|
should be useful together with the customprog and the TXB instruction
|
|
to implement blur filters with a large radius. For most OpenGL
|
|
implementations this is very slow for any non-RGB formats. Default is
|
|
disabled.
|
|
|
|
Normally there is no reason to use the following options, they mostly
|
|
exist for testing purposes.
|
|
|
|
(no-)glfinish
|
|
Call ``glFinish()`` before swapping buffers. Slower but in some cases
|
|
more correct output (default: disabled).
|
|
(no-)manyfmts
|
|
Enables support for more (RGB and BGR) color formats (default:
|
|
enabled). Needs OpenGL version >= 1.2.
|
|
slice-height=<0-...>
|
|
Number of lines copied to texture in one piece (default: 0). 0 for
|
|
whole image.
|
|
|
|
*NOTE*: If YUV colorspace is used (see `yuv` suboption), special rules
|
|
apply: If the decoder uses slice rendering (see ``--no-slices``), this
|
|
setting has no effect, the size of the slices as provided by the
|
|
decoder is used. If the decoder does not use slice rendering, the
|
|
default is 16.
|
|
(no-)osd
|
|
Enable or disable support for OSD rendering via OpenGL (default:
|
|
enabled). This option is for testing; to disable the OSD use
|
|
``--osdlevel=0`` instead.
|
|
|
|
null
|
|
Produces no video output. Useful for benchmarking.
|
|
|
|
aa
|
|
ASCII art video output driver that works on a text console. You can get a
|
|
list and an explanation of available suboptions by executing ``mplayer
|
|
--vo=aa:help``.
|
|
|
|
*NOTE*: The driver does not handle ``--aspect`` correctly.
|
|
|
|
*HINT*: You probably have to specify ``--monitorpixelaspect``. Try
|
|
``mplayer --vo=aa --monitorpixelaspect=0.5``.
|
|
|
|
caca
|
|
Color ASCII art video output driver that works on a text console.
|
|
|
|
bl
|
|
Video playback using the Blinkenlights UDP protocol. This driver is highly
|
|
hardware specific.
|
|
|
|
<subdevice>
|
|
Explicitly choose the Blinkenlights subdevice driver to use. It is
|
|
something like ``arcade:host=localhost:2323`` or
|
|
``hdl:file=name1,file=name2``. You must specify a subdevice.
|
|
|
|
ggi
|
|
GGI graphics system video output driver
|
|
|
|
<driver>
|
|
Explicitly choose the GGI driver to use. Replace any ',' that would
|
|
appear in the driver string by a '.'.
|
|
|
|
directfb
|
|
Play video using the DirectFB library.
|
|
|
|
(no-)input
|
|
Use the DirectFB instead of the MPlayer keyboard code (default:
|
|
enabled).
|
|
buffermode=single|double|triple
|
|
Double and triple buffering give best results if you want to avoid
|
|
tearing issues. Triple buffering is more efficient than double
|
|
buffering as it does not block MPlayer while waiting for the vertical
|
|
retrace. Single buffering should be avoided (default: single).
|
|
fieldparity=top|bottom
|
|
Control the output order for interlaced frames (default: disabled).
|
|
Valid values are top = top fields first, bottom = bottom fields first.
|
|
This option does not have any effect on progressive film material like
|
|
most MPEG movies are. You need to enable this option if you have
|
|
tearing issues or unsmooth motions watching interlaced film material.
|
|
layer=N
|
|
Will force layer with ID N for playback (default: -1 - auto).
|
|
dfbopts=<list>
|
|
Specify a parameter list for DirectFB.
|
|
|
|
dfbmga
|
|
Matrox G400/G450/G550 specific video output driver that uses the DirectFB
|
|
library to make use of special hardware features. Enables CRTC2 (second
|
|
head), displaying video independently of the first head.
|
|
|
|
(no-)input
|
|
same as directfb (default: disabled)
|
|
buffermode=single|double|triple
|
|
same as directfb (default: triple)
|
|
fieldparity=top|bottom
|
|
same as directfb
|
|
(no-)bes
|
|
Enable the use of the Matrox BES (backend scaler) (default: disabled).
|
|
Gives very good results concerning speed and output quality as
|
|
interpolated picture processing is done in hardware. Works only on the
|
|
primary head.
|
|
(no-)spic
|
|
Make use of the Matrox sub picture layer to display the OSD (default:
|
|
enabled).
|
|
(no-)crtc2
|
|
Turn on TV-out on the second head (default: enabled). The output
|
|
quality is amazing as it is a full interlaced picture with proper sync
|
|
to every odd/even field.
|
|
tvnorm=pal|ntsc|auto
|
|
Will set the TV norm of the Matrox card without the need for modifying
|
|
``/etc/directfbrc`` (default: disabled). Valid norms are pal = PAL,
|
|
ntsc = NTSC. Special norm is auto (auto-adjust using PAL/NTSC) because
|
|
it decides which norm to use by looking at the framerate of the movie.
|
|
|
|

|
|
images and stores it in a file (default: ``./stream.yuv``). The format is
|
|
the same as the one employed by mjpegtools, so this is useful if you want
|
|
to process the video with the mjpegtools suite. It supports the YV12
|
|
format. If your source file has a different format and is interlaced, make
|
|
sure to use ``--vf=scale=::1`` to ensure the conversion uses interlaced
|
|
mode. You can combine it with the ``--fixed-vo`` option to concatenate
|
|
files with the same dimensions and fps value.
|
|
