Why is it necessary to configure a trustable Prezi specific directory?
Prezis are indeed nothing more than swf flash files which are files in a format for multimedia, vector graphics and ActionScript in the Adobe Flash environment. So you should not need more than a flash player and the data which the player shall reload while he plays the initial swf file.
The "problem" is that that flash player may only reload files from trustable locations. And therefore you must generate such a directory. And you must configure your flash player such that he recognizes this trustable directory.
Use Prezi Presentations On GUN/Linux In Offline Mode
A Wonderful Packed Solution
The Elder Do-It-Yourself-Method
Normally you can present Prezi-Presentations using two methods:
- You can use the online presentation mode offered by the Prezi site itself (http://www.prezi.com/).
- Or you can download a presentation-zip file which includes a Prezi-Presentation Application (prezi.exe) for executing an offline presentation.
Unfortunately this app is a windows app. But luckily the kernel off a Prezi-Presentation is a flash file. So we "only" have to "extract" the pure flash file data if we want to present a Prezi-Presentation on an Ubuntu Linux System. On the internet this idea was already described in a more general way. For all the sticklers of detail I list all single steps here:
- Install a modern Ubuntu System like Lucid Lynx and its firefox package.
- Install adobe-flashplugin using synaptic
- Generate a new top-directory for all your Prezi-Presentations.
- Call the Adobe-Flash-Configurator being offered as Adobe Web-Flash-Application.
- Using the buttons "Edit locations" (offered in the tab "Global Security Settings") and the button "Add location" (being embedded into the called dialog) add your generated prezi-top-directory as a location from which the flash player always trusts new reloadable files.
- Goto http://www.prezi.com/ and load down your Prezi-presentation as zip file ("export to Portable prezi to present offline").
- Unzip the zip file inside of your prezi-top-directory (by which your generate the prezi-specific-top-directory)
- Change into the generated prezi-specific-top-directory.
- Call a shell and insert "mv prezi.app/Contents/Resources/movie.swf ."
- Open the Firefox and open the file "prezi-top-directory/prezi-specific-top-directory/movie.swf"
