unix command to record audio or movie with quicktime?

[pressure]

I saw this cool little feature and was wondering, what is the unix command to record a movie or audio file with quicktime?

http://www.apple.com/uk/pro/tips/cameratoquicktime.html

launch the QuickTime Pro Player, then from the File menu choose New Movie Recording. A QuickTime window will open showing you a preview of what your camera is seeing. Now just click the round red record button at the bottom of the QuickTime window and it starts recording. Click the stop button when you’ve finished and you’ve got an instant QuickTime movie.

I wasn't aware there was a command line interface for quicktime.

You could write an AppleScript to control QT Player and invoke that from a shell script.

Just tested this.

tell application "QuickTime Player"
	
	set nr to (new movie recording)
	set nr to start recording true
	delay 10
	set nr to stop recording true
end tell

Also look in the Applescript QT dictionary for more info.

Using Haynes Ash shell script

I can set up ash abbreviations to the commands which allows a quick and easy way to do this from the command line.

ash> -abbrev qtr tell application "QuickTime Player" to new movie recording
ash> -abbrev qtrst tell application "QuickTime Player" to start recording true
ash> -abbrev qtrsp tell application "QuickTime Player" to stop recording true
ash>

The -abbrev command does Not save once you exit ASH.
So I created the ~/.ashrc file and saved the commands into it so they would load when ASH starts.

Hayne this worked really well.

Note that you could of course have saved these commands into any text file of your choosing (e.g. "qtcmds.txt" or "qtcmds.ash" or whatever) and then used "-source" to bring those commands into the 'ash' environment when needed.

By the way (for other readers), the 'ash' scripting environment referred to is:
