 ====Project goals====
   * Make a computer look like a media player.
@@ Line 5: / Line 7: @@
   * Make it usable only by remote control.
   * Make it able to play anything!
+TODO
+  * Figure out how to use cvidix (nVidia console output).
+  * Figure out how to use ''splashy'' or equals to remove text boot screen.
+  * Look at ''setterm'' command (-blank 0) for disabling the blanking of the screen during playback.
+  * Use Qingy for login (autologin)
+  * Parse and play on-demand tv.
+  * Use mplayer menu for program browsing.
+  * Create image viewer
+  * Make DVD menus work. (http://wonkabar.org/archives/405)
+  * Make 'save checkpoint' function (http://www.mplayerhq.hu/DOCS/HTML/en/edl.html)

+===Framebuffer===
+First of all we must make sure we have framebuffer support. My box is running with an nVidia GF4 MX card, so I'll be using the nVidia framebuffer driver alongside the VESA one.
+<code>
+Device Drivers  --->
+   Graphics support  --->
+      <*> Support for frame buffer devices
+      ---   Frame buffer hardware drivers
+      <*>   Userspace VESA VGA graphics support
+      [*]   VESA VGA graphics support
+      <*>   nVidia Framebuffer Support
+      [*]     Enable DDC Support
+      [*]     Lots of debug output
+      [*]     Support for backlight control
+      < >   nVidia Riva support
+      Console display driver support  --->
+         --- VGA text console
+        [*]   Enable Scrollback Buffer in System RAM
+        (1024)  Scrollback Buffer Size (in KB)
+        ---   Video mode selection support
+        <*> Framebuffer Console support
+</code>
+More info on the Framebuffer subject can be found at http://gentoo-wiki.com/HOWTO_Framebuffer_Support.
+===RAM disk===
+Furthermore I'll be using a graphical boot splash screen, so I'll need RAM disk support (initrd) for gensplash to work properly.
+<code>
+General setup  --->
+   [*] Initial RAM filesystem and RAM disk (initramfs/initrd) support
+   (4096) Initramfs source file(s)
+   (0)     User ID to map to 0 (user root) (NEW)
+   (0)     Group ID to map to 0 (group root) (NEW)
+Device Drivers  --->
+   [*] Block devices  --->
+      --- Block devices
+      <*>   RAM disk support
+      (16)    Default number of RAM disks
+      (4096)  Default RAM disk size (kbytes)
+      (1024)  Default RAM disk block size (bytes)
+</code>
+The rest of the system will be using ALSA for the sound card (with oss simulation), and the proper CPU, IDE, etc drivers.

 </code>
+Connect mplayer and irc with commands like this:
+<code>
+begin
+     button = VolUp
+     prog = mplayer
+     config = volume 1
+     repeat = 1
+end
+</code>
+See lirc capable events in [[http://www.mplayerhq.hu/DOCS/tech/slave.txt]].
+====Autologin====
+Autologin with mingetty.
+<code>
+emerge -va mingetty
+</code>
+Change the ''/etc/inittab'' to
+<code>
+# TERMINALS
+#c1:12345:respawn:/sbin/agetty 38400 tty1 linux
+c1:12345:respawn:/sbin/mingetty --noclear --autologin root tty1
+c2:2345:respawn:/sbin/agetty 38400 tty2 linux
+c3:2345:respawn:/sbin/agetty 38400 tty3 linux
+c4:2345:respawn:/sbin/agetty 38400 tty4 linux
+c5:2345:respawn:/sbin/agetty 38400 tty5 linux
+c6:2345:respawn:/sbin/agetty 38400 tty6 linux
+</code>
+====irexec====
+To be able to use the ir when not in mplayer, use and start the irexec service (comes with the lirc package). This is a dummy host that can be use to trigger events just like any other app.\\
+This example cathes the key ''One'' and runs the script ''dr1''.
+<code>
+begin
+   prog = irexec
+   button = One
+   repeat = 0
+   config = dr1
+end
+</code>
+====Speed down cdrom/dvd drive====
+When playing a movie or some music a high speed cdrom/dvd drive ca be pretty annoying.\\
+A simple ''eject -x 4 /dev/cdrom'' will try to set the speed of the drive after a mount has occurred. If no medium is present, the command will fail.
