Question

Can CF read current time from a video playing on page?

I would like to be able to play a video on a webpage and synchronize content changes on the page as the video plays. One example would be having PowerPoint slides change on the page as a video presentation played. Is there anything built into CF that would assist in this? Thanks!

    Not built into ColdFusion, because ColdFusion runs on the server, and a playing video would be running on the client.  These computers could be thousands of miles apart.

    Now with Flash, Flex, AIR clients, there are probably plenty of ways to do something like you are desiring.  But those technologies are covered more thoroughly in forums dedicated to them.

    Now if you want to tie these events to new requests for more data from the ColdFusion server, the latest ColdFusion does offer several options that might very well tie into whatever is created for the Client side.

    Thanks for the quick reply. I've seen this done with javascript, but I'm js illiterate. I thought I had seen some .NET programming that automatically wrote the js for you, and thought there might be an CF equivilent. It seems like something like this should be pretty easy to accomplish, but CF alone may not be able to do it.

    I'll look into that tag more, to see if it's been implemented anywhere in the way that I would like to use it. I've done quite a bit of searching on this, but haven't found much. There are services that will do this for you and host the media on their site, but I really need to have full control and local hosting. Thanks very much for your help.


    Lol, running a Google search on that tag brought up this thread. Google must be quick today.

    I found a page with some sample code that seems to indicate that I can at least get the current time from the video. That might be enough to get me started, I might just have to learn enough js to accomplish this.
