FBGrab Deamon 1.0
Created by Willems Davy / Gunnar Monell
 
What Is It ?
Fbgrab is a program that lets you take screenshots from games and emulators.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 Caanoo 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 the "joystick click button" to make a screenshot and it's being saved with the date & time in the filename:

I=0
II=0
Y=0
A=0
B=0
X=0
L=0
R=0
HOME=0
JOYSTICK=1
USEDATETIME=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 directories and ini files to the apps 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 when USEDATETIME is set to 0 otherwise it will generate filenames based on the date and time. This is done so it will never overwrite an existing screenshot ! The daemon saves the screenshots in in the /mnt/sd/photo/screenshotsXX directory the XX is for the color depth which depends on the version you run (24/16 bit).

Notes:
The program will kill (using killall) any previous running FBGrab daemon so you don't have to reboot the caanoo when you accidently ran it twice or choose to change to another bitdepth version. Only one instance of the daemon can be run at any time to prevent multiple screenshots being taken

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 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 !

If your screenshots look garbled try using a diffrent bitdepth daemon, i only included 24 bit (which the default menu uses) and 16 bit version (which most games use i guess).

Certain games produce black screenshots, i haven't figured out why yet (propis is such a game).
