when I use Videocapture of opencv2.x to save a video like video = VideoWriter("camera.avi", CV_FOURCC('X', 'V', 'I', 'D'), 32, cvSize(int(capture.get(CV_CAP_PROP_FRAME_WIDTH)), int(capture.get(CV_CAP_PROP_FRAME_HEIGHT))));
it is ok to open xvid encoder ,but when i use opencv3.0 xvid encoder is not open at all, I don't kown how to sovle this problem ,please help !!!!!
You cannot used this: cvSize(int(capture.get(CV_CAP_PROP_FRAME_WIDTH)), int(capture.get(CV_CAP_PROP_FRAME_HEIGHT))));
frame_width = int(cap.get(3))
frame_height = int(cap.get(4))
# Define the codec and create VideoWriter object.The output is stored in 'outpy.avi' file.
out = cv2.VideoWriter('outpy.avi',cv2.VideoWriter_fourcc('M','J','P','G'), 10, (frame_width,frame_height))
Or if you prefer this:
# Define the codec and create VideoWriter object
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('output.avi',fourcc, 20.0, (640,480))

run in windows 10
all functionality for that is inside the opencv_ffmpeg.dll . make sure it's on the PATH or next to your app
YES,I find problem is in opencv_ffmpeg.dll,when I delete it ,encoder opens.But another problem happened,because I use webcam, deleting opencv_ffmpeg.dll will make it broken down,what should I do,thanks
