After struggling with Firefox, I managed to get GeoVids working in Chrome and recently had to re-install the GeoVids plugin. Now GeoVids finds the files but when you click on the Video button, chrome displays
<h4 style=”box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; border: 0px; font-style: normal; font-variant: normal; font-weight: 500; font-stretch: inherit; font-size: 18px; line-height: 1.1; font-family: oswaldbook, Arial, sans-serif; vertical-align: baseline; color: #a94442; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 1; word-spacing: 0px; -webkit-text-stroke-width: 0px;”>Google Chrome doesn’t support plugins anymore. Please consider using other browser.</h4>
Given the above and the problems with Firefox only supporting one video file and Explorer not working at all, I wonder if it’s time to consider re-working GeoVids as a server- based application using YouTube Videos instead of trying to get the client computer to do the work which would seem to have too many variables that you cannot control.
Here are some examples of dual players
OK this may not allow you to overlay the track display on the video as you can with GeoVids but it would allow easier syncing (via a jog-wheel style interface and/or by specifying the time offset).
It may require a minimum screen size or you could allow the viewer to position the video player where they want on the screen.
The other option is to allow users to upload their video files to your server for processing but that would require extensive storage capacity.
