save detected result and video file as a input about face_classification

[mirceaciu]

You can alter the script to do what you want. This are basic python jobs

To save result:

if emotion_text == 'angry':
    color = emotion_probability * np.asarray((255, 0, 0))
    file_to_write = open('myfile.csv', 'a')
    file_to_write.write('angry,')
    file_to_write.close()

To read from video file just replace 0(that represents video camera) with the path to the video file:
video_capture = cv2.VideoCapture("path/video/file.mp4")

This isn't a issue per se.

@mirceaciu @oarriaga What i mean here is to save the result as video file like .mp4 or .avi as i know cv2.VideoWriter_fourcc with different codec can be used but it is producing me an error like:

cv2.error: /home/rohit/opencv-3.3.0/modules/imgcodecs/src/loadsave.cpp:604: error: (-2) could not find a writer for the specified extension in function imwrite_

Can you advice me what can be done to save the result as video file ?
