Joyrider’s FbGrabDaemon – Capture Dingoo screens in Dingux

FBGrab Deamon Version
What Is It ?
Fbgrab is a program that lets you take screenshots from games and emulators, however up until now it was only possible to use fbgrab from a commandline console (telnet).
I made the fbgrab program into a deamon so that it keeps running in the background and listens for a certain keypress (specified in the keyconfig file), if the key (combination)
has been pressed it will make a screenshot of whatever you are currently seeing on the dingoo screen.
How To use ?
first edit the keyconfig file to your liking, you can specify key combinations by just editing the current config file setting 1 if the key needs to be pressed or 0 if it doesn't.
for example this is the default keyconfig file where you'll have to press L+R+UP to make a screenshot:
SELECT=0
START=0
UP=1
LEFT=0
DOWN=0
RIGHT=0
Y=0
A=0
B=0
X=0
L=1
R=1
Do not delete any of the "not used keys" and also do not change the order of the file, after you have chosen your configiration, copy the fbgrab.dge and keyconfig file into a directory on your sd
and start the program. You won't see anything come up on the screen so when using a menu you will be returned directly back to it after running fbgrab.dge. The deamon should be running
now and whenever you press the key combination you have choosen a new screenshot will be generated in your local directy named Screenshot1.png, Screenshot2.png, Screenshot3.png... etc
It will never overwrite an existing screenshot !
Notes:
DO NOT RUN THE PROGRAM TWICE,
it doesn't make your dingoo explode but you will get double screenshots ! (obviously).
DO NOT FORGET TO COPY THE KEYCONFIG FILE AND DO NOT SET ALL KEYS TO 0
failing to do so will make the deamon keep taking screenshots
if you changed the keyconfig file while the deamon was already running you'll have to reboot the dingoo (or kill the previous running deamon process somehow) and restart the fbgrab deamon.
I couldn't figure out a way to let you (the user) know if they screenshot was succesfull or not (i tried audio and writing to the framebuffer but both were not a great option).
Anyway just test it out by using the default config and see if it creates your screenshots !
