I am trying to make a daemon that checks if mplayer is running (it's for a projection room) and if it is not then to run mplayer with a file..
Not exactly what a daemon is for IMO, but that's not for here to discuss

What exactly isn't working. I found a few things that might cause problems, but that could or couldn't be what you're looking for.
As a guideline, a daemon usually has this workflow:
Your code, OTOH, never goes into background, and, in case mplayer keeps on crashing, will waste quite some time on process creation.
In your ChildProcess() function you could replace the execvp/exit combination with a simple exec, as this will replace the current process image (that of the child) with that of the program you're specifying.
