Problem with external program launch
Hello,
in the application i'm writing i need to launch "recordmydesktop" to capture the screen,but i'm having a problem: when the recording stops,and the encoding of the saved file starts,the entire system hangs until the completion of the encoding.This happens if i launch recordmydesktop from my application (simply by clicking a button).
Now what is weird is:if i start recordmydesktop by opening a shell and starting it manually (with my app already running),the encoding doesn't generate any hang.....
The only difference i noticed is the different priority level that recordmydesktop gets when starting from the shell,which is lower than my app's one (i.e. a higher priority number),while when i start it from my app it gets the same of my application,which has a higher priority level.
I tried to start recordmydesktop using the fork and exec approach,giving a lower priority with the "nice" system call,but nothing seems to be better.....
Do you have any advice?
Thanks in advance!
