Oh,
and I want to add that waiting for the child processes also seems to be
missing. At least that's what the amount of zombies seems to suggest:
thinkpad:/home/dd# ps ax |grep xdg-screensaver

If I look at #374644, I find
+ if(fork() == 0) {
+ execvp(args[0], args);
+ _exit(0);
}
which confirms my assumption of unproper forking.
If I manually kill all xdg-screensaver instances, I can successfully
reopen the XVDR plugin.
If I change the TV channel, playback again breaks, again with
xdg-screensaver instances running and blocking the audio file handles
(three of them actually.)
I hope this is sufficient information to fix this bug.
Regards,
Daniel
