hello, In Inventory/video ads- player info there is a download button for "Download the appropriate plugin for your video player": flowplayer, jwplayer, custom. What these plugins are for, because if I create a in line video banner, I can get the vast xml without these plugins. For instance, the custom plugin is called: openvideoads.vast.as3.tar What I do with this file? It is not a plugin for revive server, or it is? If yes how can I install it? thank you!
