on_xxxx Feature Discussion

Proposal

Motion has some config options to start external programs or scripts when a certain event has occurred. These options are following:

execute	at start of event
onsave	picture saved
onmpeg	movie started
onffmpegclose	movie ended
mail	send mail at start of event
sms	send sms at start of event

The naming is not consistent nor very clear to the user. Some are missing (end of event) and others are not flexible enough (mail: sender address not configurable).

This is how the script commands should look like:

Function	Old Option	New Option	Argument Appended
Start of event (first motion)	execute	on_event_start	None
End of event (no motion for gap seconds)	New!	on_event_end	None
Picture saved (jpg or ppm)	onsave	on_picture_save	Filename of picture
Movie starts (mpeg file opened)	onmpeg	on_movie_start	Filename of movie
Movie ends (mpeg file closed)	onffmpegclose	on_movie_end	Filename of movie
Motion detected (each single frame with Motion detected)	New!	on_motion_detected	None

Mail and sms can be removed. They are executed today, when an event starts. This funtionality can be built using the on_event_start script with even more flexibility than we have today.
