  1. Hi Bram,

    thanks for this very useful example. Since I am just getting up to speed with developing using javascript etc., this example helped a lot. I am trying the example on a low cost Android phone with a bad camera. The image is not sharp enough if the distance between the camera and the barcode is small. Question: The getUserMedia does not seem to have the option to enable autofocus, correct? I am experimenting with some sharpening filters etc., but I am not exactly there where I want to be.
    Thanks a lot!

  2. Cant get this to work out of the box.
    What do i miss?
    Are there any requirements need?

  3. Can’t get any code? Did you delete your repository? Really sad, there’s no good working barcode recognition library like ZBar for JavaScript. The only one is … but it doesn’t work very well.

    1. Hi Andre,

      The code was created by @dieterprovoost. Looks like he deleted it. Unfortunately I don’t have a fork nor clone.
