I working on a video composition project using multiple user generated videos . Below is my code
df=pd.concat(user,axis=1)
print df
dfs= df.loc[:, (slice(None), ['Panning','sec'])]
video_index=0 cap=cv2.VideoCapture(videoList[0]) width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH)) height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT)) fps = cap.get(cv2.CAP_PROP_FPS) fra=[] fourcc = cv2.VideoWriter_fourcc(*'DIVX') out = cv2.VideoWriter("Output.avi", fourcc, fps, (width, height), True) while(cap.isOpened()): ret,frame=cap.read() fra.append(frame)
for index,row in dfs.iterrows():
if (row[:, 'Panning'] == 'Panning').any():
idx = row[:, 'Panning'][row[:, 'Panning'] == 'Panning'].index.tolist()
sec = int(row.loc[(idx, 'sec')].values.tolist()[0])
if cap.get(0)==1000*sec:
cap = cv2.VideoCapture(videoList[indices.index(random.choice(idx))])
cap.set(0, sec * 1000)
ret, frame = cap.read()
fra.append(frame)
else:
#cap = cv2.VideoCapture(videoList[indices.index(random.choice(idx))])
ret,frame=cap.read()
fra.append(frame)
if frame is None:
video_index += 1
if video_index == len(videoList):
break
cap = cv2.VideoCapture(videoList[indices.index(long_dur())])
cap.set(0,1000*sec)
ret, frame = cap.read()
fra.append(frame)
When I am trying to run I am get the following error
OpenCV Error: Unspecified error (The numpy array of typenum=2, ndims=3 can not be created) in NumpyAllocator::allocate, file ..\..\..\modules\python\src2\cv2.cpp, line 184

I am not able to solve it.need help on this error
