-

i have created web page (that has video embeded in it) using google app engine , html5. there python code detecing smile.what should invoke python code when play button clicked (i.e.)when video starts play automatically viewers face should detected... app engine code given below....

    import webapp2      class mainpage(webapp2.requesthandler):     def get(self):      self.response.out.write("""<!doctype html>             <html>                       <body>               <video width="320" height="240" controls>             <source src="/video/mov_bbb.mp4" type="video/mp4">             <source src="/video/mov_bbb.ogg" type="video/ogg">              browser not support video tag.             </video>             </body>             </html>""")      app = webapp2.wsgiapplication([('/', mainpage)])

the app.yaml file is....

    application: video     version: 1     runtime: python27     api_version: 1     threadsafe: true      handlers:     - url: /video      static_dir: video      - url: /.*     script: video.app      - url: /(.*\.mp4)     static_files: video/\1     mime_type: video/mp4     upload: video/(.*\.mp4)      - url: /(.*\.ogg)     static_files: video/\1     mime_type: video/ogg     upload: video/(.*\.ogv)

the python code smile detection is....

    import cv      haar_cascade_path = "haarcascade_smile.xml"      camera_index = 0      def detect_faces(image):              faces = []              detected = cv.haardetectobjects(image, cascade, storage, 1.1,99,0,(40,40))     if detected:            (x,y,w,h),n in detected:                     faces.append((x,y,w,h))            return faces      if __name__ == "__main__":             cv.namedwindow("video", cv.cv_window_autosize)              capture = cv.capturefromcam(camera_index)             storage = cv.creatememstorage()             cascade = cv.load(haar_cascade_path)              faces = []              = 0             c = -1             while (c == -1):                  image = cv.queryframe(capture)                   #only run detection algorithm every 5 frames improve performance                  if i%5==0:                        faces = detect_faces(image)                   (x,y,w,h) in faces:                        cv.rectangle(image, (x,y), (x+w,y+h), 255)                   cv.showimage("video", image)                     += 1                  c = cv.waitkey(10)

you can't.

the video streamed client browser , played on client browser. since it's running in browser, you'll need run smile detection code in browser. it'll have javascript instead of python.
