[vlc-devel] [PATCH] Add:: Static Detect Video FIlter

From: basOS G <noxelia 4t gmail , com>

Static detect detects stationary images within a video and takes snapshots of them.
It is fully parametrized to account for videos with different amount of irrelevant motion
(e.g. noise). Main parameters are motion tolerance and stationary time. The module is
called static. Full parameter description with vlc -p static --advanced.

+   June 28, email from Peter Tirsek (peter at tirsek dot com):
+
+   This number represents the fixed frequency of the original PC XT's
+   timer chip (the 8254 AFAIR), which is approximately 1.193 MHz. This
+   number is divided with the desired frequency to obtain a counter value,
+   that is subsequently fed into the timer chip, tied to the PC speaker.
+   The chip decreases this counter at every tick (1.193 MHz) and when it
+   reaches zero, it toggles the state of the speaker (on/off, or in/out),
+   resets the counter to the original value, and starts over. The end
+   result of this is a tone at approximately the desired frequency. :)
