  • Merge individual frame to video file using Opencv and FFmpeg

    16 août 2022, par Rohit

    I am trying to stack a individual frame to a video file using Opencv. I want to combine two different code together to make the individual frame.
Following code help me extract the individual frame

    


    while True:
ret, frame=cap.read()
mask = object_detector.apply(frame)
_, mask  = cv2.threshold(mask,254,255,cv2.THRESH_BINARY)       
contours,_ = cv2.findContours(mask, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
res = cv2.bitwise_and(frame,frame,mask=mask)
for cnt in contours:
    area = cv2.contourArea(cnt)
    if area>1000:   
        #print("Area of contour:", area)
        cv2.drawContours(frame, [cnt], -1, (0,255,0),2)
        cv2.imwrite("file%d.jpg"%count, frame)


    


    And I attach the frame together separately using following code using ffmpeg command

    


    ffmpeg -r 3 -i frame%03d.jpg -c:v libx264 -vf fps=25 -pix_fmt yuv420p video.mp4


    


    I tried storing the individual frame in array, but it didn't work. It doesn't show any error, but pc crash.
