Where is the classic player (flash)

[Martijn de Jong]

We have a problem: For more then a year we used this project to show our Prezi presentations on our custom build chromium (Library to create browser in .NET based on Chrome's engine) application. We cannot use the WebGL function and need the Flash player. This all worked fine until a few days ago. We noticed that we could edit a Prezi (classic) bit not play it. When we want to play the Prezi it gives a message that Flash player 11.1 is requird, our application includes Flash version 23 (and we can edit Prezi's, so flash is working).

When we look at the HTML-code of the page that the Prezi player loads trough the Iframe, we can see this "Need flash" message, but we cannot find the code that loaded a Flash object. Could anyone tell me if the Flash Player code was removed, is it coming back, how can we load the Flash Player trough this project? Please help!

I cannot understand why the classic player was removed. Embedded devices that use flash can work great with Prezi classic but not with the new html5 (webgl) player. Why does this project does not give a lagacy version?

what kind of devices are you referring to? Can you help us with real use-cases? We are optimising for web browsers, and to support both core and next prezis.

We are using Intel Compute Sticks (Atom X5) to display presentations. But this issue can also be seen if you disable WebGL in a normal Chrome browser.

To reproduce:

1. Use latest Chrome browser (Windows), startup parameter: "--disable-webgl" to disable the WebGL feature in the browser.
2. Goto: https://prezi.com/_ueivw8ad8xx/prezi-demo/?webgl=0, notice that it correctly fallback to Flash player.
3. Goto: http://prezi.github.io/prezi-player/, notice that there is a "Prezi needs Flash Player 11.1" error, it does not fallback to flash player. It does not metter if we add the "?webgl=0" parameter to the iframe URL, also the code inside the iframe seems to miss code for the Flash object.

This issue is only for the Prezi Player API, the embed feature (code for the iframe to load the /embed/ page) is working, but we need the API functions.

Thank you, very useful info with the hardware!

Although I am afraid we won't support the flash player anymore for the Prezi Player API, we are thinking about some other fallback option for devices not supporting WebGL.

It would be wonderful to get the flash player back, perhaps via a "legacy" url? The previous version of the api worked great for us, now we cannot use the software that was created for us. Could you publish the original API version /files?
