osx - OpenCV (3.1.0) video saving in Python (3.5.1) on Mac -


i following opencv documentation on video saving using following code. 

import numpy np import cv2  cap = cv2.videocapture(0) height = int(cap.get(4)) width = int(cap.get(3)) fourcc = cv2.videowriter_fourcc(*'xvid') out = cv2.videowriter('output.avi', fourcc, 20.0, (width, height))  while(cap.isopened()):     ret, frame = cap.read()     if ret==true:         frame = cv2.flip(frame,0)           out.write(frame)          cv2.imshow('frame',frame)         if cv2.waitkey(1) & 0xff == ord('q'):             break     else:         break cap.release() out.release() cv2.destroyallwindows()

when run it, works fine video file saved can't opened vlc/quick time etc.

from opencv video saving in python i've noticed can change fourcc -1 allowing pick codec if on windows machine. can't on mac (osx 10.11.12).

i have tried bunch of other fourcc options, none seem work on mac.

any suggestions?

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
