snapshot_filename

• Type: String
• Range / Valid values: Max 4095 characters
• Default: %v-%Y%m%d%H%M%S-snapshot
• Option Topic

File path for snapshots (jpeg or ppm) relative to target_dir.

Default value is equivalent to legacy 'oldlayout' option. For Motion 3.0 compatible mode (directories based on date and time) choose: %Y/%m/%d/%H/%M/%S-snapshot

File extension .jpg or .ppm is automatically added so do not include this A symbolic link called lastsnap.jpg (or lastsnap.ppm) created in the target_dir will always point to the latest snapshot, unless snapshot_filename is exactly 'lastsnap'

This option uses conversion specifiers which are codes that start by % and then a letter. The conversion specifiers used has the same function as for the C function strftime (3). The most commonly used are:

• %Y = year
• %m = month as two digits
• %d = date
• %H = hour
• %M = minute
• %S = second
• %T = HH:MM:SS

These are unique to motion

• %v = event
• %q = frame number
• %t = thread (camera) number
• %D = changed pixels
• %N = noise level
• %i = width of motion area
• %J = height of motion area
• %K = X coordinate of motion center
• %L = Y coordinate of motion center
• %C = value defined by text_event

If you are happy with the directory structures the way they were in earlier versions of motion use %v-%Y%m%d%H%M%S-snapshot for 'oldlayout on' and %Y/%m/%d/%H/%M/%S-snapshot for 'oldlayout off'.

For the equivalent of the now obsolete option 'snap_overwrite' use the value 'lastsnap'.
