    Status: Open => Answered

RaiMan proposed the following answer:
If you want to detect, wether the video stops at a time it should not do
that, then looking for changed pixels with the foreground observer is
not the right way, because your script will simply hang at the
observer(), when the video stops.

Hence you have to use the background observe() (see version 2 in comment
#3), to be able to check, that nothing changed within the last x
seconds.

But for your purpose, the following might be sufficient:

r = GetAppRegion(app_name) #some function that returns an app region

img = capture(r)
wait(1)
while not r.exists(Pattern(img).similar(0.99), 0):
    wait(1)
    img = capture(r)
    wait(1)
print "video seems to have stopped"

this takes an image of the region, waits 1 second and then checks,
wether the region content is still the same - if not, waits 1 second and
starts all over.
