Web Widget - Image WebCam |
||||
|
========================= |
||||
|
|
||||
|
This module extends the functionality of the image widget and allows to take snapshots with WebCam. |
||||
|
|
||||
|
Configuration |
||||
|
============= |
||||
|
|
||||
|
By default, the module works with all `major browsers |
||||
|
<https://github.com/jhuckaby/webcamjs#browser-support>`_. |
||||
|
|
||||
|
An important note for **Chrome 47+** users - this module only works with websites delivered over SSL / HTTPS. |
||||
|
Visit this for `more info |
||||
|
<https://github.com/jhuckaby/webcamjs#important-note-for-chrome-47>`_. |
||||
|
|
||||
|
But, If you still want this module to work with websites without SSL / HTTPS. |
||||
|
Here is the steps to do it easily (Always run in Adobe Flash fallback mode, but it is not desirable). |
||||
|
|
||||
|
Set the configuration parameter ``web_widget_image_webcam.flash_fallback_mode`` to ``1`` |
||||
|
|
||||
|
Its done! Now this module also work with websites without SSL / HTTPS. |
||||
|
|
||||
|
