  2. In my Case this error is coming node index.js

    const image = cv.imencode('.jpg', frame).toString('base64');
    Io::Imencode – OpenCV Error: (Raw image encoder error: Empty JPEG image (DNL not supported)) in throwOnEror, in file /home/ashish/usb/node_modules/opencv-build/opencv/opencv/modules/imgcodecs/src/grfmt_base.cpp, line 145, status -10

  3. Im using same code but my image element is updating way to slow. Is anyone having a problem with there image element lagging? Why is yours real time and mine 5 seconds behind?

  4. Hey Cody, your videos are really good, why are not you doing more of them ? You diction and speaking manor is great for non english speakers as me for ex. You should definitely do some series, or may be some little projects.

  5. Ya dude, thanks for the video bro. I actually just checked out another one and I checked out yours with hopes that you would answer my question as to why my program was loading frames so slow. So I see that I'm probably having a processing problem. Thank you.
