I am trying to run two functions at the same time. One function is supposed to detect scenes from local video and the other should detect scenes from my webcam. Then I make some processing with these scenes. Here is the code snippet:
scenes_1 = []
scenes_2 = []
scene_manager1 = SceneManager()
scene_manager1.add_detector(ContentDetector(threshold=30.0))
scene_manager2 = SceneManager()
scene_manager2.add_detector(ContentDetector(threshold=30.0))
def callback_1(image, frame_num):
global scenes_1
print("callback_1: Found a scene on video 1.")
scenes_1 += [(image, frame_num)]
def callback_2(image, frame_num):
global scenes_2
print("callback_2: Found a scene on video 2.")
scenes_2 += [(image, frame_num)]
def function_1():
video_capture_0 = BrowserVideoCapture(src=0)
while True:
ret0,frame0=video_capture_0.read()
if(ret0):
scene_manager1.detect_scenes(frame0, callback=callback_1)
else:
break
video_capture_0.release()
def function_2():
video_capture_1 = cv2.VideoCapture("Our Story.mp4")
while True:
ret1,frame1=video_capture_1.read()
if(ret1):
scene_manager2.detect_scenes(frame1, callback=callback_2)
if cv2.waitKey(34) & 0xFF == ord('q'):
break
else:
break
video_capture_1.release()
cv2.destroyAllWindows()
t1=threading.Thread(target=function_1)
t2=threading.Thread(target=function_2)
t1.start()
t2.start()
t1.join()
t2.join()
while True:
for im, frame_num in scenes_2:
tar_image_example = cv2.cvtColor(im, cv2.COLOR_BGR2RGB)
tar_image_example = tar_image_example.astype(np.uint8)
print("Found scene at frame %d in video 2." % frame_num)
for im, frame_num in scenes_1:
src_image_example = cv2.cvtColor(im, cv2.COLOR_BGR2RGB)
src_image_example = src_image_example.astype(np.uint8)
print("Found scene at frame %d in video 1." % frame_num)
But I get the following error:
Exception in thread Thread-29:

What am I doing wrong, please?
