Python script runtime error: frame_resize = cv2.resize(frame, None, fx=1 / DOWNSAMPLE_RATIO, fy=1 / DOWNSAMPLE_RATIO)

When I run "generate_train_data.py", it would failed with error:

OpenCV Error: Assertion failed (ssize.area() > 0) in resize, file /Users/jenkins/miniconda/1/x64/conda-bld/conda_1486587097465/work/opencv-3.1.0/modules/imgproc/src/imgwarp.cpp, line 3229

It seems that the error only occurred when I use my video file recorded by myself, the https://dl.dropboxusercontent.com/s/2g04onlkmkq9c69/angela_merkel_speech.mp4 would not cause it.

Is there anyone who solve this issue? I had this problem when I import the video I made.
