Since we can configure which modes are available (and remove the download option) it would be nice if there could be a way to have an event be called when there are no supported players/formats based on the parameters we have passed in. That way we can give a message to the user telling them to download flash, upgrade their browser, etc.
I mentioned it in this thread:
I like the idea you suggested even better, that makes it applicable to more use cases.
I don't mean to grave dig this thread, but I see that there is a ticket open for this feature request ( http://developer.longtailvideo.com/trac/ticket/1450 ) and I would like to add my voice of support.
I currently use the method mentioned above by Jeroen, that results in the alternate content being visible on page loading before the player initialises; it works but it is much less than ideal.
This will very, very likely be part of the next update: player 6.0.
We're now wrapping the 5.9 player.
That's a good idea, we'll add that as a ticket. Perhaps we should just fire the onReady() event at all times, and then add the rendering mode (flash/html5/download/none) as a parameter.
For now, you could place this "install Flash" message inside the <div> you use for writing the player. If the player cannot find a rendering mode, it will leave the original div contents untouched.
