13
workarounds this, probably by using the 3D engine to zoom, and the YUV

21
Using the <span class="bold"><strong>matroxfb modules</strong></span> in the 2.4
22
kernels. 2.2 kernels don't have the TVout feature in them, thus unusable
23
for this. You have to enable ALL matroxfb-specific feature during
24
compilation (except MultiHead), and compile them into
25
<span class="bold"><strong>modules</strong></span>!
26
You'll also need I2C enabled.
27
</p><div class="procedure"><ol type="1"><li><p>
28
Enter <tt class="filename">TVout</tt> and type
29
<span><strong class="command">./compile.sh</strong></span>. Install
30
<tt class="filename">TVout/matroxset/matroxset</tt>
31
somewhere into your <code class="envar">PATH</code>.
33
If you don't have <span><strong class="command">fbset</strong></span> installed, put
34
<tt class="filename">TVout/fbset/fbset</tt>
35
somewhere into your <code class="envar">PATH</code>.
37
If you don't have <span><strong class="command">con2fb</strong></span> installed, put
38
<tt class="filename">TVout/con2fb/con2fb</tt>
39
somewhere into your <code class="envar">PATH</code>.
41
Then enter into the <tt class="filename">TVout/</tt>
42
directory in the <span class="application">MPlayer</span> source, and execute
43
<tt class="filename">./modules</tt> as root. Your text-mode console will
44
enter into framebuffer mode (no way back!).
46
Next, EDIT and run the <tt class="filename">./matroxtv</tt> script. This will
47
present you to a very simple menu. Press <span class="keycap"><b>2</b></span> and
48
<span class="keycap"><b>Enter</b></span>. Now you should have the same picture on your
49
monitor, and TV. If the TV (PAL by default)
50
picture has some weird stripes on it, the script wasn't able to set the
51
resolution correctly (to 640x512 by default). Try other resolutions
52
from the menu and/or experiment with fbset.
54
Yoh. Next task is to make the cursor on tty1 (or whatever) to
55
disappear, and turn off screen blanking. Execute the following
58
</p><pre class="screen">
60
setterm -blank 0</pre><p>
62
</p><pre class="screen">
64
setterm -blank 0</pre><p>
66
You possibly want to put the above into a script, and also clear the
67
screen. To turn the cursor back:
68
</p><pre class="screen">echo -e '\033[?25h'</pre><p> or
69
</p><pre class="screen">setterm -cursor on</pre><p>
71
Yeah kewl. Start movie playing with
72
</p><pre class="screen">
73
mplayer -vo mga -fs -screenw 640 -screenh 512 <em class="replaceable"><code>filename</code></em></pre><p>
75
(If you use X, now change to matroxfb with for example
76
<span class="keycap"><b>Ctrl</b></span>-<span class="keycap"><b>Alt</b></span>-<span class="keycap"><b>F1</b></span>.)
77
Change <code class="literal">640</code> and <code class="literal">512</code> if you set
78
the resolution to other...

94
TV output support for these cards has only been recently introduced, and is
95
not yet in the mainstream kernel.
96
Currently the <span class="bold"><strong>mga_vid</strong></span> module can't be used
97
AFAIK, because the G450/G550 driver works only in one configuration: the first
98
CRTC chip (with much more features) on the first display (on monitor),
99
and the second CRTC (no <span class="bold"><strong>BES</strong></span> - for
100
explanation on BES, please see the G400 section above) on TV. So you can only
101
use <span class="application">MPlayer</span>'s <span class="emphasis"><em>fbdev</em></span> output
102
driver at the present.
104
The first CRTC can't be routed to the second head currently. The author of the
105
kernel matroxfb driver - Petr Vandrovec - will maybe make support for this, by
106
displaying the first CRTC's output onto both of the heads at once, as currently
107
recommended for G400, see the section above.
109

Currently ATI doesn't want to support any of its TV-out chips under Linux,
113
because of their licensed Macrovision technology.

On other cards, just use the <a href="vesa.html" title="8.13. VESA - output to VESA BIOS">VESA</a> driver,

133

I will not describe the installation and configuration process because it does
140
not cover the scope of this documentation.
142
After XFree86, XVideo, and 3D acceleration is properly working, edit your
143
card's Device section in the <tt class="filename">XF86Config</tt> file, according
144
to the following example (adapt for your card/TV):
146
</p><pre class="programlisting">
150
BoardName "nVidia GeForce2/MX 400"
154
Option "CursorShadow" "on"
157
Option "TwinViewOrientation" "Clone"

159
Option "ConnectedMonitor" "CRT, TV"
160
Option "TVStandard" "PAL-B"
161
Option "TVOutFormat" "Composite"

The NeoMagic chip is found in a variety of laptops, some of them are equipped
168
with a simple analog TV encoder, some have a more advanced one.

</p><div class="itemizedlist"><ul type="disc"><li><p>
170
<span class="bold"><strong>Analog encoder chip</strong></span>:
171
It has been reported that reliable TV out can be obtained by using
172
<tt class="option">-vo fbdev</tt> or <tt class="option">-vo fbdev2</tt>.
173
You need to have vesafb compiled in your kernel and pass
174
the following parameters on the kernel command line:
175
<tt class="option">append="video=vesafb:ywrap,mtrr" vga=791</tt>.
176
You should start <span class="application">X</span>, then switch to console mode
178
<span class="keycap"><b>Ctrl</b></span>-<span class="keycap"><b>Alt</b></span>-<span class="keycap"><b>F1</b></span>.
179
If you fail to start <span class="application">X</span> before running
180
<span class="application">MPlayer</span> from the console, the video
181
becomes slow and choppy (explanations are welcome).
182
Login to your console, then initiate the following command:
184
</p><pre class="screen">clear; mplayer -vo fbdev -zoom -cache 8192 dvd://</pre><p>
186
Now you should see the movie running in console mode filling up about
187
half your laptop's LCD screen. To switch to TV hit
188
<span class="keycap"><b>Fn</b></span>-<span class="keycap"><b>F5</b></span> three times.
189
Tested on a Tecra 8000, 2.6.15 kernel with vesafb, ALSA v1.0.10.
191
<span class="bold"><strong>Chrontel 70xx encoder chip</strong></span>:
192
Found in IBM Thinkpad 390E and possibly other Thinkpads or notebooks.
194
You must use <tt class="option">-vo vesa:neotv_pal</tt> for PAL or
195
<tt class="option">-vo vesa:neotv_ntsc</tt> for NTSC.
196
It will provide TV output function in the following 16 bpp and 8 bpp modes:
197
</p><div class="itemizedlist"><ul type="circle"><li><p>NTSC 320x240, 640x480 and maybe 800x600 too.</p></li><li><p>PAL 320x240, 400x300, 640x480, 800x600.</p></li></ul></div><p>Mode 512x384 is not supported in BIOS. You must scale the image
198
to a different resolution to activate TV out. If you can see an image on the
199
screen in 640x480 or in 800x600 but not in 320x240 or other smaller
200
resolution you need to replace two tables in <tt class="filename">vbelib.c</tt>.
201
See the vbeSetTV function for details. Please contact the author in this case.
203
Known issues: VESA-only, no other controls such as brightness, contrast,
204
blacklevel, flickfilter are implemented.
