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.
