-DirectFB includes TV out support for Matrox G400 cards.
-If you've used the Windows drivers you most likely know about
-DVDMax... DirectFB provides the same functionality. Now you can get
-excellent quality video playback on your TV.
-
-DirectFB TV output features:
-- interlaced picture
-- 720x576 50Hz PAL and 720x486 60Hz NTSC
-- RGB15, RGB16, RGB32, ARGB, YUY2, UYVY, I420, YV12 pixel formats
-- hardware blended sub-picure in I420 and YV12 modes
-- brightness, contrast, hue, saturation adjustments
-- no more tweaking sessions with fbset to get the image centered :)

-I recommend you use DirectFB 0.9.15 or later since some vsync problems
-were fixed in that release.
-
-Linux kernel setup:
-
-1. Patch your kernel with matroxfb-vsync-c2vline-irq-patch-2.4.19.bz2
-It's distributed with DirectFB sources in the patches subdirectory.
-This patch enables IRQ based vblank waiting. Make sure your card has
-an IRQ assigned to it. You may have an option in the BIOS setup for
-this.
-
-2. Add "#define FBIO_WAITFORVSYNC _IOW('F', 0x20, int)" to
- /usr/include/linux/fb.h
-
-3. Build and install the kernel. Set the following options:
- CONFIG_I2C
- CONFIG_I2C_ALGOBIT
- CONFIG_I2C_CHARDEV
- CONFIG_I2C_PROC
- CONFIG_FB_MATROX
- CONFIG_FB_MATROX_G100
- CONFIG_FB_MATROX_I2C
-DirectFB doesn't require kernel support for the second head. In fact it may
-interfere with the TV out.
-
-4. Make sure you have the proper /dev/i2c-N device file in place.
- After loading i2c-matroxfb module you should see MAVEN in
- /proc/bus/i2c. You must have the corresponding device file. To
- create these files use:
- 'mknod /dev/i2c-N c 89 N' where N is 0,1,2...
- The number might change depending on the order you load i2c modules
- so you may want to create some extra files.
-
-DirectFB setup:
-
-1. Build and install DirectFB
-
-2. Use the following DirectFB options:
- matrox-crtc2
- matrox-tv-standard=pal or ntsc
-You can store them in /etc/directfbrc or ~/.directfbrc so that the will be
-used every time.
-
-That's pretty much it. Well you do need some applications. mplayer has
-a special video out plugin 'dfbmga' for this stuff. You need a recent
-version of mplayer to use it.
