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