.SH "VIDEO OUTPUT DRIVERS (MPLAYER ONLY)"
Video output drivers are interfaces to different output facilities.
The syntax is:
.TP
.B \-vo <driver1[:suboption1[=value]:...],driver2,...[,]>
Specify a priority list of video output drivers to be used.
.PP
If the list has a trailing ',' it will fall back to drivers not listed on the
command line.
Suboptions are optional and can mostly be omitted.

Very simple version, no OSD support and video size must be smaller than
the maximum texture size of your OpenGL implementation.
Intended to work even with the most simple OpenGL implementations.
.PD 0
.RSs
.IPs manyfmts
Enables support for more (RGB and BGR) color formats.
Needs OpenGL version >= 1.2, NOT yet WORKING correctly.
.IPs slice-height=<0\-...>
Number of lines copied to texture in one piece (default: 4).
0 for whole image.

.B ggi\ \ \ \
Output driver for the GGI graphics system.
.TP
.B directfb
Play video using the DirectFB library.
.PD 0
.RSs
.IPs (no)input
Use the DirectFB instead of the MPlayer keyboard code (default: enabled).
.IPs buffermode=single|double|triple
Double and triple buffering give best results if you want to avoid tearing issues.
Triple buffering is more efficent than double buffering as it doesn't block MPlayer
while waiting for the vertical retrace.
Single buffering should be avoided (default: single).
.IPs 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 doesn't have any effect on progressive film material
like most MPEG movies are.
You need to enable this option if you have tearing issues/unsmooth
motions watching interlaced film material.
.IPs layer=N
Will force layer with id N for playback (default: -1 - auto).
.RE
.PD 1
.TP
.B dfbmga\
Matrox G400/G450/G550 specific output driver that uses the DirectFB library.
Enables CRTC2 (second head), displaying video independently of the first head.
.PD 0
.RSs
.IPs (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.
.IPs (no)spic
Make use of the Matrox sub picture layer to display the OSD (default: enabled).
.IPs (no)crtc2
Turn on TV-out on the second head (default: enabled).
The output quality is amazing as it's a full interlaced picture
with proper sync to every odd/even field.
.IPs (no)input
Use the DirectFB instead of the MPlayer keyboard code (default: disabled).
.IPs buffermode=single|double|triple
Double and triple buffering give best results if you want to avoid tearing issues.
Triple buffering is more efficent than double buffering as it doesn't block MPlayer
while waiting for the vertical retrace.
Single buffering should be avoided (default: triple).
.IPs fieldparity=top|bottom

This option doesn't have any effect on progressive film material
like most MPEG movies are.
You need to enable this option if you have tearing issues/unsmooth
motions watching interlaced film material.
.IPs 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 frame rate of the movie.
.RE
