|
||
<A NAME=2.2.1.1>2.2.1.1. MTRR
|
||
|
||
Nagyon ajánlott az MTRR helyes beállítása, mert minden esetben
|
||
sebességnövekedést eredményez. Először a báziscímet kell megkeresni.
|
||
Erre van 3 módszer :
|
||
|
||
- az X11 induló üzeneteiből, például :
|
||
|
||
(--) SVGA: PCI: Matrox MGA G400 AGP rev 4, Memory @ 0xd8000000, 0xd4000000
|
||
(--) SVGA: Linear framebuffer at 0xD8000000
|
||
|
||
- a /proc/pci-ből (használd az lspci -v parancsot):
|
||
|
||
01:00.0 VGA compatible controller: Matrox Graphics, Inc.: Unknown device 0525
|
||
Memory at d8000000 (32-bit, prefetchable)
|
||
|
||
- az mga_vid kernel meghajtó üzeneteiből (dmesg parancs):
|
||
|
||
mga_mem_base = d8000000
|
||
|
||
Ezután kell a memória mérete is. Csak át kell konvertálni a video ram
|
||
méretét hexadecimálisba, pl így :
|
||
|
||
|
||
1 MB 0x100000
|
||
2 MB 0x200000
|
||
4 MB 0x400000
|
||
8 MB 0x800000
|
||
16 MB 0x1000000
|
||
32 MB 0x2000000
|
||
|
||
|
||
Már tudjuk a címet és a méretet, már csak a beállítás hiányzik!
|
||
Például a fenti Matrox kártyához (base=0xd8000000), 32mega memóriával
|
||
(size=0x2000000) ezt kell beírni:
|
||
|
||
|
||
echo "base=0xd8000000 size=0x2000000 type=write-combining" >| /proc/mtrr
|
||
|
||
|
||
Nem minden CPU támogatja az MTRR-eket. Például régebbi K6/2-k (266Mhz
|
||
körül, stepping 0) nem, de stepping 12-esek igen (cat /proc/cpuinfo
|
||
megadja a stepping értékét).
|
||
|
||
|
||
<A NAME=2.2.1.2>2.2.1.2. Xv
|
||
|
||
XFree86 4.0.2 vagy újabb alatt használhatod a kártyád hardware-es YUV
|
||
rutinjait, az XVideo kiterjesztéssel. Ezt használja a '-vo xv' opció.
|
||
Hogy működjön, a következő feltételeknek kell teljesülniük :
|
||
- XFree86 4.0.2 vagy újabb kell (előző verziókban nincs XVideo)
|
||
- A kártyádnak tudnia kell hardware-es gyorsítást (a mai kártyák tudják)
|
||
- Az X-nek be kell töltenie az XVideo kiterjesztést, valahogy így néz ki:
|
||
|
||
|
||
(II) Loading extension XVideo
|
||
|
||
|
||
a /var/log/XFree86.0.log file-ban.
|
||
|
||
|
||
MEGJ : ez csak az XFree86 kiterjesztését tölti be. Egy rendes installban
|
||
ez az alap, és nem azt jelenti, hogy a _kártyád_ XVideo támogatása
|
||
töltődött be!
|
||
|
||
- A kártyád Linuxos drivere támogatja-e az Xv-t. Ezt az 'xvinfo'-val lehet
|
||
megnezni, ez pedig az XFree86 disztribúció része. Egy hosszú szöveget
|
||
kell hogy kiírjon, hasonlót ehhez:

<A NAME=2.2.1.2.1>2.2.1.2.1. 3dfx kártyák
|
||
|
||
Régebbi 3dfx meghajtóknak problémái vannak az XVideo gyorsítással,
|
||
nem támogatták a YUY2-t vagy YV12-t, ésígytovább. Ellenőrizd hogy az
|
||
XFree86-od verziója 4.1.0 vagy újabb-e, azok már jók.
|
||
Ha furcsa effekteket észlelsz -vo xv-vel, próbáld ki az SDL meghajtót
|
||
(annak is van XVideo támogatása), az segíthet. Nézd meg a <A HREF="#2.2.1.4">2.2.1.4-es</A>
|
||
fejezetet a részletekhez.
|

||
|
||
<A NAME=2.2.1.2.2>2.2.1.2.2. S3 kártyák
|
||
|
||
S3 Savage3D-knek működniük kell, de Savage4-hez 4.0.3-as de inkább újabb
|
||
XFree86 kell. S3 Virge-re vonatkozólag.. add el.
|
||
|
||
|
||
<A NAME=2.2.1.2.3>2.2.1.2.3. nVidia kártyák
|
||
|
||
nVidia nem túl jó választás Linux alá.. A bináris nVidia meghajtót kell
|
||
használnod, ami az nVidia honlapjáról tölthető le. A szabvány X
|
||
meghajtó nem tartalmaz XVideo támogatást ezekhez a kártyákhoz, mivel
|
||
az nVidia nem adja ki a specifikációikat.
|
||
|
||
- Riva128-as kártyáknak még az nVidia meghajtóval se lesz XVideo-juk :(
|
||
Panaszkodj az nVidiának.
|
||
|
||
|
||
<A NAME=2.2.1.2.4>2.2.1.2.4. ATI kártyák
|
||
|
||
A GATOS meghajtó alapállapotban bekapcsolt VSYNC-et tartalmaz. Ez azt
|
||
jelenti, hogy a dekódolási sebesség (!) hozzá van szinkronizálva a monitor
|
||
frissítési frekvenciájához. Ha a lejátszás lassúnak tűnik, próbáld meg
|
||
valahogy kikapcsolni a VSYNC-et, vagy állítsd a képfrissítést n*(a film
|
||
fps-e) Hz-re.

||
<A NAME=2.2.1.3>2.2.1.3. DGA
|
||
|
||
<A NAME=2.2.1.3.1>2.2.1.3.1. Előszó
|
||
|
||
Ez a dokumentum néhány szóban elmagyarázza, hogy általában véve mi is az a
|
||
DGA, és mit tud az MPlayerben (és mit nem).
|
||
|
||
|
||
<A NAME=2.2.1.3.2>2.2.1.3.2. Mi az a DGA ?
|
||
|
||
A DGA szó a Direct Graphics Access rövidítése, és egy olyan módszert takar,
|
||
amivel a program az X szerver kikerülésével közvetlenül írhat a framebuffer
|
||
memóriába. Szaknyelven szólva ez a framebuffer memóriának a processz
|
||
területére történő lapozásával történik. Ezt a kernel csak root jogosultsággal
|
||
engedi. Ez történhet root-ként történő bejelentkezéssel, vagy a suid bit
|
||
beállításával az mplayer programon (NEM ajánlott!).
|
||
|
||
A DGA-nak két verziója van: a DGA1-et az XFree 3.X.X használja, a DGA2
|
||
pedig az XFree 4.0.1 óta létezik.
|
||
|
||
A DGA1 csak a fent leírt közvetlen hozzáférést nyújtja. A felbontásváltáshoz
|
||
itt szükség van az XVidMode kiterjesztésre.
|
||
|
||
A DGA2 tartalmazza az XVidMode tudását, továbbá engedélyezi a színmélység
|
||
megváltoztatását. Így lehetséges, hogy egy 32 bites mélységű X szervert
|
||
átváltsunk 15 bitesbe, vagy fordítva.
|
||
|
||
A DGA-nak van néhány hátránya. Valamelyest függ a grafikus chiptől és ennek
|
||
X-es driverétől, ezért nem minden rendszeren működik ...
|
||
|
||
|
||
<A NAME=2.2.1.3.3>2.2.1.3.3. DGA támogatás telepítése <B>MPlayer</B>-be
|
||
|
||
Először bizonyosodj meg arról, hogy az X betölti-e a DGA kiterjesztést, lásd
|
||
/var/log/XFree86.0.log :
|
||
|
||
|
||
(II) Loading extension XFree86-DGA
|
||
|
||
|
||
Amint látod, XFree86 4.0.x vagy újabb, NAGYON AJÁNLOTT!
|
||
Az <B>MPlayer</B> DGA meghajtója ./configure közben automatikusan
|
||
detektálódik, de az --enable-dga opcióval megerősítheted.
|
||
|
||
Ha a meghajtó
|
||
If the driver couldn't switch to a smaller resolution, experiment with
|
||
switches -vm (only with X 3.3.x), -fs, -bpp, -zoom to find a video mode that
|
||
the movie fits in. There is no converter right now.. :(
|
||
|
||
Become ROOT. DGA needs root access to be able to write directly video memory.
|
||
If you want to run it as user, then install <B>MPlayer</B> SUID root:
|
||
|
||
|
||
chown root /usr/local/bin/mplayer
|
||
chmod 750 /usr/local/bin/mplayer
|
||
chmod +s /usr/local/bin/mplayer
|
||
|
||
|
||
Now it works as a simple user, too.
|
||
|
||
|
||
!!!! BUT STAY TUNED !!!!
|
||
This is a BIG security risk! Never do this on a server or on a computer
|
||
can be accessed by more people than only you because they can gain root
|
||
privilegies through suid root mplayer.
|
||
!!!! SO YOU HAVE BEEN WARNED ... !!!!
|
||
|
||
|
||
Now use '-vo dga' option, and there you go! (hope so:)
|
||
You should also try if the '-vo sdl:dga' option works for you! It's much
|
||
faster!!!
|
||
|
||
|
||
<A NAME=2.2.1.3.4>2.2.1.3.4. Resolution switching
|
||
|
||
The DGA driver allows for switching the resolution of the output signal.
|
||
This avoids the need for doing (slow) software scaling and at the same
|
||
time provides a fullscreen image. Ideally it would switch to the exact
|
||
resolution (except for honouring aspect ratio) of the video data, but the
|
||
XServer only allows switching to resolutions predefined in
|
||
/etc/X11/XF86Config (/etc/X11/XF86Config-4 for XFree 4.0.X respectively).
|
||
Those are defined by so-called modelines and depend on the capabilites
|
||
of your video hardware. The XServer scans this config file on startup and
|
||
disables the modelines not suitable for your hardware. You can find
|
||
out which modes survive with the X11 log file. It can be found at:
|
||
/var/log/XFree86.0.log
|
||
See appendix A for some sample modeline definitions.
|
||
|
||
|
||
<A NAME=2.2.1.3.5>2.2.1.3.5. DGA & <B>MPlayer</B>
|
||
|
||
DGA is used in two places with <B>MPlayer</B>: The SDL driver can be made to make
|
||
use of it (-vo sdl:dga) and within the DGA driver (-vo dga).
|
||
The above said is true for both; in the following sections I'll explain
|
||
how the DGA driver for <B>MPlayer</B> works.
|
||
|
||
|
||
<A NAME=2.2.1.3.6>2.2.1.3.6. Features of the DGA driver
|
||
|
||
The DGA driver is invoked by specifying -vo dga at the command line.
|
||
The default behaviour is to switch to a resolution matching the original
|
||
resolution of the video as close as possible. It deliberately ignores the
|
||
-vm and -fs switches (enabling of video mode switching and fullscreen) -
|
||
it always tries to cover as much area of your screen as possible by switching
|
||
the video mode, thus refraining to use a single additional cycle of your CPU
|
||
to scale the image.
|
||
If you don't like the mode it chooses you may force it to choose the mode
|
||
matching closest the resolution you specify by -x and -y.
|
||
By providing the -v option, the DGA driver will print, among a lot of other
|
||
things, a list of all resolutions supported by your current XF86-Config
|
||
file.
|
||
Having DGA2 you may also force it to use a certain depth by using the -bpp
|
||
option. Valid depths are 15, 16, 24 and 32. It depends on your hardware
|
||
whether these depths are natively supported or if a (possibly slow)
|
||
conversion has to be done.
|
||
|
||
If you should be lucky enough to have enough offscreen memory left to
|
||
put a whole image there, the DGA driver will use doublebuffering, which
|
||
results in much smoother movie replaying. It will tell you whether double-
|
||
buffering is enabled or not.
|
||
|
||
Doublebuffering means that the next frame of your video is being drawn in
|
||
some offscreen memory while the current frame is being displayed. When the
|
||
next frame is ready, the graphics chip is just told the location in memory
|
||
of the new frame and simply fetches the data to be displayed from there.
|
||
In the meantime the other buffer in memory will be filled again with new
|
||
video data.
|
||
|
||
Doublebuffering may be switched on by using the option -double and may be
|
||
disabled with -nodouble. Current default option is to disable
|
||
doublebuffering. When using the DGA driver, onscreen display (OSD) only
|
||
works with doublebuffering enabled. However, enabling doublebuffering may
|
||
result in a big speed penalty (on my K6-II+ 525 it used an additional 20% of
|
||
CPU time!) depending on the implementation of DGA for your hardware.
|
||
|
||
|
||
<A NAME=2.2.1.3.7>2.2.1.3.7. Speed issues
|
||
|
||
Generally spoken, DGA framebuffer access should be at least as fast as using
|
||
the X11 driver with the additional benefit of getting a fullscreen image.
|
||
The percentage speed values printed by mplayer have to be interpreted with
|
||
some care, as for example, with the X11 driver they do not include the time
|
||
used by the X-Server needed for the actual drawing. Hook a terminal to a
|
||
serial line of your box and start top to see what is really going on in your
|
||
box ...
|
||
|
||
Generally spoken, the speedup done by using DGA against 'normal' use of X11
|
||
highly depends on your graphics card and how well the X-Server module for it
|
||
is optimized.
|
||
|
||
If you have a slow system, better use 15 or 16bit depth since they require
|
||
only half the memory bandwidth of a 32 bit display.
|
||
|
||
Using a depth of 24bit is even a good idea if your card natively just supports
|
||
32 bit depth since it transfers 25% less data compared to the 32/32 mode.
|
||
|
||
I've seen some avi files already be replayed on a Pentium MMX 266. AMD K6-2
|
||
CPUs might work at 400 MHZ and above.
|
||
|
||
|
||
<A NAME=2.2.1.3.8>2.2.1.3.8. Known bugs
|
||
|
||
Well, according to some developpers of XFree, DGA is quite a beast. They
|
||
tell you better not to use it. Its implementation is not always flawless
|
||
with every chipset driver for XFree out there.
|
||
|
||
o with XFree 4.0.3 and nv.o there is a bug resulting in strange colors
|
||
o ATI driver requires to switch mode back more than once after finishing
|
||
using of DGA
|
||
o some drivers simply fail to switch back to normal resolution (use
|
||
Ctrl-Alt-Keypad +, - to switch back manually)
|
||
o some drivers simply display strange colors
|
||
o some drivers lie about the amount of memory they map into the process's
|
||
address space, thus vo_dga won't use doublebuffering (SIS?)
|
||
o some drivers seem to fail to report even a single valid mode. In this
|
||
case the DGA driver will crash telling you about a nonsense mode of
|
||
100000x100000 or the like ...
|
||
o OSD only works with doublebuffering enabled

<A NAME=2.2.1.4>2.2.1.4. SDL
|
||
|
||
Here are some notes about SDL out in <B>MPlayer</B>.
|
||
|
||
There are several commandline switches for SDL:
|
||
|
||
-vo sdl:name specifies sdl video driver to use (ie. aalib,
|
||
dga, x11)
|
||
-ao sdl:name specifies sdl audio driver to use (ie. dsp,
|
||
esd, arts)
|
||
-noxv disables Xvideo hardware acceleration
|
||
-forcexv tries to force Xvideo acceleration
|
||
|
||
SDL Keys:
|
||
|
||
F toggles fullscreen/windowed mode
|
||
C cycles available fullscreen modes
|
||
W/S mappings for * and / (mixer control)

KNOWN BUGS:
|
||
- Keys pressed under sdl:aalib console driver repeat forever. (use -vo aa !)
|
||
It's bug in SDL, I can't change it (tested with SDL 1.2.1).

||
<A NAME=2.2.1.5>2.2.1.5. SVGAlib
|
||
|
||
If you don't have X, you can use the SVGAlib target! Be sure not to use the
|
||
-fs switch, since it toggles the usage of the software scaler, and it's
|
||
SLOOOW now, unless you have a real fast CPU (and/or MTRR?). :(
|
||
|
||
Of course you'll have to install svgalib and its development package in
|
||
order for <B>MPlayer</B> build its SVGAlib driver (autodetected, but can be
|
||
forced), and don't forget to edit /etc/vga/libvga.config to suit your
|
||
card & monitor.
|
||
|
||
|
||
<A NAME=2.2.1.6>2.2.1.6. Framebuffer output (FBdev)
|
||
|
||
Whether to build the FBdev target is autodetected during ./configure .
|
||
Read the framebuffer documentation in the kernel sources
|
||
(Documentation/fb/*) for info on how to enable it, etc.. !
|
||
|
||
If your card doesn't support VBE 2.0 standard (older ISA/PCI
|
||
cards, such as S3 Trio64), only VBE 1.2 (or older?) :
|
||
Well, VESAfb is still available, but you'll have to load SciTech Display
|
||
Doctor (formerly UniVBE) before booting Linux. Use a DOS boot disk or
|
||
whatever. And don't forget to register your UniVBE ;))
|
||
|
||
The FBdev output takes some additional parameters above the others:
|
||
|
||
-fb specify the framebuffer device to use (/dev/fd0)
|
||
-fbmode mode name to use (according to /etc/fb.modes)
|
||
-fbmodeconfig config file of modes (default /etc/fb.modes)
|
||
monitor_hfreq
|
||
monitor_vfreq IMPORTANT values, see example.conf
|
||
monitor_dotclock
|
||
|
||
If you want to change to a specific mode, then use
|
||
|
||
mplayer -vm -fbmode (NameOfMode) filename
|
||
|
||
-vm alone will choose the most suitable mode from /etc/fb.modes . Can be
|
||
used together with -x and -y options too. The -flip option is supported only
|
||
if the movie's pixel format matches the video mode's pixel format.
|
||
Pay attention to the bpp value, fbdev driver tries to use the current,
|
||
or if you specify the -bpp option, then that.
|
||
-zoom option isn't supported (software scaling is slow). -fs option
|
||
isn't supported. You can't use 8bpp (or less) modes.
|
||
|
||
NOTE: FBdev video mode changing _does not work_ with the VESA framebuffer,
|
||
and don't ask for it, since it's not an <B>MPlayer</B> limitation.

<A NAME=2.2.1.7>2.2.1.7. Matrox framebuffer (mga_vid)
|
||
|
||
This section is about the Matrox G200/G400/G450 BES (Back-End Scaler)
|
||
support, the mga_vid kernel driver. It's active developed by me (A'rpi), and
|
||
it has hardware VSYNC support with triple buffering. It works on both
|
||
framebuffer console and under X.
|
||
|
||
To use it, you first have to compile mga_vid.o :
|
||
|
||
|
||
cd drivers
|
||
make
|
||
|
||
|
||
Then create /dev/mga_vid device :
|
||
|
||
|
||
mknod /dev/mga_vid c 178 0
|
||
|
||
|
||
and load the driver with
|
||
|
||
|
||
insmod mga_vid.o
|
||
|
||
|
||
You should verify the memory size detection using the 'dmesg' command. If
|
||
it's bad, use the mga_ram_size option (rmmod mga_vid first), specify card's
|
||
memory size in MB:
|
||
|
||
|
||
insmod mga_vid.o mga_ram_size=16
|
||
|
||
|
||
To make it load/unload automatically when needed, insert the following line
|
||
at the end of /etc/modules.conf :
|
||
|
||
|
||
alias char-major-178 mga_vid
|
||
|
||
|
||
Then run
|
||
|
||
|
||
depmod -a
|
||
|
||
|
||
Now you have to (re)compile <B>MPlayer</B>, ./configure will detect /dev/mga_vid
|
||
and build the 'mga' driver. Using it from <B>MPlayer</B> goes by '-vo mga' if
|
||
you have matroxfb console, or '-vo xmga' under XFree86 3.x.x or 4.x.x .
|
||
|
||
Note: '-vo xmga' works under XFree86 4.x.x, but it conflicts with the Xv
|
||
driver, so avoid using both. If you messed up Xv with mga, try running
|
||
<B>MPlayer</B> with '-vo mga' . It should fix Xv.
|
||
|
||
|
||
<A NAME=2.2.1.8>2.2.1.8. SiS 6326 framebuffer (sis_vid)
|
||
|
||
SiS 6326 YUV Framebuffer driver -> sis_vid kernel driver
|
||
|
||
Its interface should be compatible with the mga_vid, but the driver was not
|
||
updated after the mga_vid changes, so it's outdated now. Volunteers
|
||
needed to test it and bring the code up-to-date.
|
||
|
||
|
||
<A NAME=2.2.1.9>2.2.1.9. 3dfx YUV support
|
||
|
||
3dfx has native YUV+scaler support, using /dev/3dfx (tdfx.o driver?)
|
||
The /dev/3dfx kernel driver exists only for 2.2.x kernels, for use with
|
||
Glide 2.x Linux ports. It's not tested with <B>MPlayer</B>, and so no more
|
||
supported. Volunteers needed to test it and bring the code up-to-date.
|
||
|
||
|
||
<A NAME=2.2.1.10>2.2.1.10. OpenGL output
|
||
|
||
<B>MPlayer</B> support displaying movies using OpenGL. Unfortunately, not all
|
||
drivers support this ability. For example the Utah-GLX drivers
|
||
(for XFree86 3.3.6) have it, with all cards.
|
||
See <A HREF="http://utah-glx.sourceforge.net">http://utah-glx.sourceforge.net</A> for details about how to install it.
|
||
|
||
XFree86(DRI) >= 4.0.3 supports it only with Matrox, and Radeon cards.
|
||
See <A HREF="http://dri.sourceforge.net">http://dri.sourceforge.net</A> for download, and installation instructions.
|
||
|
||
|
||
<A NAME=2.2.1.11>2.2.1.11. AAlib - text mode displaying
|
||
|
||
<B>AAlib</B> is a library for displaying graphics in text mode, using powerful
|
||
ASCII renderer. There are LOTS of programs already supporting it, like Doom,
|
||
Quake, etc. MPlayer contains a very usable driver for it.
|
||
If ./configure detects aalib installed, the aalib libvo driver will be built.
|
||
|
||
You can use some keys in the AA Window to change rendering options:
|
||
1 : decrease contrast
|
||
2 : increase contrast
|
||
3 : decrease brightness
|
||
4 : increase brightness
|
||
5 : switch fast rendering on/off
|
||
6 : set dithering mode (none, error distribution, floyd steinberg)
|
||
7 : invert image
|
||
a : toggles between aa and mplayer control)
|
||
|
||
|
||
|
||
The following command line options can be used:
|
||
-aaosdcolor=V : change osd color
|
||
-aasubcolor=V : change subtitle color
|
||
where V can be: (0/normal, 1/dark, 2/bold, 3/boldfont, 4/reverse, 5/special)
|
||
|
||
AAlib itselves provides a large sum of options.
|
||
Here are some important:
|
||
-aadriver : set recommended aa driver (X11, curses, linux)
|
||
-aaextended : use all 256 characters
|
||
-aaeight : use eight bit ascii
|
||
-aahelp : prints out all aalib options
|
||
|
||
|
||
|
||
|
||
|
||
NOTE: the rendering is very CPU intensive, especially when using AA-on-X
|
||
(using aalib on X), and it's least CPU intensive on standard,
|
||
non-framebuffer console. Use SVGATextMode to set up a big textmode,
|
||
then enjoy! (secondary head Hercules cards rock :)) (anyone can enhance
|
||
fbdev to do conversion/dithering to hgafb? Would be neat :)
|
||
|
||
Use the -framedrop option if your comp isn't fast enough to render all frames!
|
||
|
||
Playing on terminal you'll get better speed and quality using the linux driver, not
|
||
curses (-aadriver linux). But therefore you need write access on /dev/vcsa<terminal>!
|
||
That isn't autodetected by aalib, bu vo_aa tries to find the best mode.
|
||
See http://aa-project.sourceforge.net/tune/ for further tuning issues.

<A NAME=2.2.1.A>2.2.1.A. TV-out support
|
||
|
||
|
||
<A NAME=2.2.1.A.1>2.2.1.A.1. Matrox cards
|
||
|
||
<I> What I'd love to see in mplayer is the the same feature that I see in my
|
||
windows box. When I start a movie in windows (in a window or in full screen)
|
||
the movie is also redirected to the tv-out and I can also see it full screen
|
||
on my tv. I love this feature and was wondering how hard it would be to add
|
||
such a feature to mplayer.</I>
|
||
|
||
It's a driver limitation. BES (Back-End Scaler, it's the overlay generator
|
||
and YUV scaling engine of G200/G400/G450 cards) works only with CRTC1.
|
||
Normally, CRTC1 (textmode, every bpp gfx and BES) is routed to HEAD1,
|
||
and CRTC2 (only 16/32bpp gfx) is routed to HEAD2 (TV-out).
|
||
|
||
Under linux, you have two choices to get TV-out working:
|
||
|
||
1. Using X 4.0.x + the HAL driver from matrox, so you'll get dual-head
|
||
support, and you'll be able to redirect second output to the TV.
|
||
Unfortunately it has Macrovision encryption enabled, so it will
|
||
only work on directly-connected TV, no through VCR.
|
||
Other problem is that Xv doesn't work on the second head.
|
||
(I don't know how Windows solve it, maybe it swaps the CRTCs between
|
||
the heads, or just uses YUV framebuffer of second DAC with some trick)
|
||
|
||
2. Using matroxfb with dual-head support enabled (2.4.x kernels).
|
||
You'll be able to get a framebuffer console (using CRTC2, so it's
|
||
slow), and TV-out (using CRTC1, with BES support).
|
||
You have to forget X while using this kind of TV-out! :(
|
||
|
||
- Compile all the matrox-related things to modules in the kernel.
|
||
(you MUST compile them to modules, at least I couldn't get them
|
||
working built-in yet)
|
||
[reboot to new kernel & install modules, but don't load them yet!]
|
||
|
||
cd TVout
|
||
./compile.sh
|
||
|
||
- Run the 'modules' script from the TV-out directory of mplayer.
|
||
It will switch your console to framebuffer.
|
||
Change to tty1 (ALT+F1)!
|
||
Now run the script 'independent', it will set up your tty's:
|
||
tty 1,2: fb console, CRTC2, head 1 (monitor)
|
||
tty 3,4,5...: framebuffer+BES, CRTC1, head 2 (TV-out)
|
||
You should run the scripts TV-* and Mon-* to set up resolutions:
|
||
change to tty1 (ALT+F1), and run Mon-* (one of them)
|
||
change to tty3 (ALT+F3) and then back to tty1 (ALT+F1)
|
||
(this change will select tty3 on /dev/fb1 - tricky)
|
||
run TV-* (one of them)
|
||
(now you'll get a console on your PAL TV - don't know about NTSC)
|
||
|
||
Now if you start mplayer (on tty1), the picture will show up on
|
||
the tty3, so you'll see it on your TV or second monitor.
|
||
|
||
Yes, it is a bit 'hack' now. But I'm waiting for the marvel
|
||
project to be finished, it will provide real TV-out drivers, I hope.
|
||
|
||
My current problem is that BES is working only with CRTC1. So picture
|
||
will always shown up on head routed to CRTC1 (normaly the monitor),
|
||
so i have to swap CRTC's, but this way your console will framebuffer
|
||
(CRTC2 can't do text-mode) and a bit slow (no acceleration). :(
|
||
|
||
|
||
<I> anyway i also just get monochrome output on the tv ...</I>
|
||
Maybe you have NTSC TV? Or just didn't run one of TV-* scripts.
