I’m using this webpage webcam recorder script, that works successfully.
I’d like some help with how the screen appears upon seeing the webpage.
Currently, upon seeing the web page it looks like the 1st image attached, titled: ‘BeforeStart’.
And after Start Recording button is selected, the screen appears like the 2nd image attached, titled: ‘Start’
I’d like, upon initially seeing the web page, I’d like the visitor to first see how the image ‘Start’ appears", which would be having the webcam activated, but no recording yet (until the Start Recording button is selected.
I hope that makes sense. Any help will be appreciated. Here’s the current code:
