Always run the update, before any install!!

apt-get update

And then install the package.

apt-get install software-properties-common

It worked!

exec() not executing – command in two diferent lines

f*ck!

i’v been struggling with avconv, exec, chown and all that sh*ts this last two days!
’cause i was trying to preform a  exec to avconv to create some screencaps and the command was  in two lines…

echo $avconScreenScroll = 'avconv -i '.$destFolder.'/' . $dataVideos['videos'][$key]['videoFilename'] . '
 -vsync 1 -s 150x100 -qscale 1 -r 1 -an -y ' . $screencapsDir . '/scroll/img%03d.jpg';
 exec($avconScreenScroll);

 

Minimize the CPU usage of a process?

To limit CPU usage of the process called avconv to 70%, enter:

cpulimit -e avconv -l 30

To limit CPU usage of the process to 70% by using its PID, enter:

cpulimit -p 6969 -l 70

If the process isn’t running cpulimit will wait for it.
