Starting an external, independent process from a script

[rishi pathak]

You can do something like this:
pid = os.fork()
if pid != 0:
    os.execl("mencoder variables here and its arguments")
else:
    continue
exec will replace the current child process with the given command and as we
are doing fork the command will get executed in a child process.You can also
use os.system there
