You can create a simple script, say, /usr/local/bin/capture and give
permissions to lauch it as root via sudo.
Script might be one-liner like
#!/bin/sh
exec nice -n -10 ionice -c 1 capture-command
and sudo line might look like this:
user ALL=(root) NOPASSWD: /usr/local/bin/capture
NOPASSWD here means that you just have to type
'sudo /usr/local/bin/capture' to run the script as root, no questions
asked.
