MPlayer-mingw32-1.0rc2.zip 经典播放器源码

kernel matroxfb driver - Petr Vandrovec - will maybe make support for this, by
displaying the first CRTC's output onto both of the heads at once, as currently
recommended for G400, see the section above.
</p><p>
The necessary kernel patch and the detailed HOWTO is downloadable from

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

On other cards, just use the <a class="link" href="vesa.html" title="8.13.聽VESA - output to VESA BIOS">VESA</a> driver,
without VIDIX. Powerful CPU is needed, though.
</p><p>
Only thing you need to do - <span class="bold"><strong>Have the TV connector
plugged in before booting your PC</strong></span> since video BIOS initializes
itself only once during POST procedure.

First, you MUST download the closed-source drivers from
<a class="ulink" href="http://nvidia.com" target="_top">http://nvidia.com</a>.
I will not describe the installation and configuration process because it does
not cover the scope of this documentation.
</p><p>
After XFree86, XVideo, and 3D acceleration is properly working, edit your
card's Device section in the <tt class="filename">XF86Config</tt> file, according
to the following example (adapt for your card/TV):

</p><pre class="programlisting">
Section "Device"
        Identifier      "GeForce"
        VendorName      "ASUS"
        BoardName       "nVidia GeForce2/MX 400"
        Driver          "nvidia"
        #Option         "NvAGP" "1"
        Option          "NoLogo"
        Option          "CursorShadow"  "on"

        Option          "TwinView"
        Option          "TwinViewOrientation" "Clone"
        Option          "MetaModes" "1024x768,640x480"
        Option          "ConnectedMonitor" "CRT, TV"
        Option          "TVStandard" "PAL-B"
        Option          "TVOutFormat" "Composite"
EndSection
</pre><p>
</p><p>
Of course the important thing is the TwinView part.

The NeoMagic chip is found in a variety of laptops, some of them are equipped
with a simple analog TV encoder, some have a more advanced one.
</p><div class="itemizedlist"><ul type="disc"><li><p>
  <span class="bold"><strong>Analog encoder chip</strong></span>:
  It has been reported that reliable TV out can be obtained by using
  <tt class="option">-vo fbdev</tt> or <tt class="option">-vo fbdev2</tt>.
  You need to have vesafb compiled in your kernel and pass
  the following parameters on the kernel command line:
  <tt class="option">append="video=vesafb:ywrap,mtrr" vga=791</tt>.
  You should start <span class="application">X</span>, then switch to console mode
  with e.g.
  <span class="keycap"><b>Ctrl</b></span>+<span class="keycap"><b>Alt</b></span>+<span class="keycap"><b>F1</b></span>.
  If you fail to start <span class="application">X</span> before running
  <span class="application">MPlayer</span> from the console, the video
  becomes slow and choppy (explanations are welcome).
  Login to your console, then initiate the following command:

  </p><pre class="screen">clear; mplayer -vo fbdev -zoom -cache 8192 dvd://</pre><p>

  Now you should see the movie running in console mode filling up about
  half your laptop's LCD screen. To switch to TV hit
  <span class="keycap"><b>Fn</b></span>+<span class="keycap"><b>F5</b></span> three times.
  Tested on a Tecra 8000, 2.6.15 kernel with vesafb, ALSA v1.0.10.

  <span class="bold"><strong>Chrontel 70xx encoder chip</strong></span>:
  Found in IBM Thinkpad 390E and possibly other Thinkpads or notebooks.
  </p><p>
  You must use <tt class="option">-vo vesa:neotv_pal</tt> for PAL or
  <tt class="option">-vo vesa:neotv_ntsc</tt> for NTSC.
  It will provide TV output function in the following 16 bpp and 8 bpp modes:
  </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
  to a different resolution to activate TV out. If you can see an image on the
  screen in 640x480 or in 800x600 but not in 320x240 or other smaller
  resolution you need to replace two tables in <tt class="filename">vbelib.c</tt>.
  See the vbeSetTV function for details. Please contact the author in this case.
  </p><p>
  Known issues: VESA-only, no other controls such as brightness, contrast,
  blacklevel, flickfilter are implemented.
