Testing ... (interrupt to exit)
When
evtest
prompts you to select the device, choose the
uimapper
device and then
touch away (and hold touch and double-touch). You will see the different signals that
uinput_mapper
is generating as a result of your touches. If you do not see a
uimapper
device at this screen, it means that the
uinput_mapper
service is either stopped or not
running properly.
Adding Videos
If you have not already done so, put your videos on your SSD. The SSD can be for-
matted for any filesystem that RaspBMC understands (NTFS, FAT, ext2/3/4, etc.),
and your video files can be in any directory or folder hierarchy that you want. Just be
aware that XBMC will force you to navigate through those folders to play your videos,
so we recommend keeping it as shallow as possible. You can also add music or pictures
in this same way.
Supported Encodings
By default, the Raspberry Pi hardware supports hardware decoding of only H264/
MPEG-4 video encoding. RaspBMC will try to play files that are encoded with other
video codecs, but it might have to fall back to software decoding to do so, and the
performance of that will be poor. For more details on how to add additional hard-
ware video codecs, see
Hack #47
.
When you plug the SSD into the USB hub, if RaspBMC is running, it will automatically
detect the additional drive, and you will be able to select that source for your videos
(or music/pictures). You should test it out now to make sure you can successfully
playback videos. The touchscreen has small speakers that will play the HDMI audio
being output by the Raspberry Pi.
Putting It All Together
Now that everything works properly, you just need to put it in your car. Plugging in the
power should be straightforward: you plug the touchscreen into one 12 V receptacle,
your power inverter (to household AC power plug) into another, and then plug the
