OpenCV Out of memory error

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
