If you use video in your InDesign SWF, even one from URL, InDesign exports resources folder to the same place with actual SWF. Inside that resources folder there´s a skin of the video player you chose for you video. When you upload main SWF to your server, you need to upload that resources folder as well. Because if you don´t, flash player never finds that skin and therefore can´t show any controls...
Here´s a screenshot of my main SWF (videotest.swf) I exported from InDesign. Because I placed a video from URL there, InDesign created videotest_Resources folder and inside of it there is SkinOverAll.swf... If I want everything to work smoothly, I need to upload them all.
That makes sense, however even when uploading that file to the server, the flash file isn't recognizing/using it. Is there somewhere in the embedded source code of the original file that I can add the url of the video skin so it'll work?
A solution I have seen posted elsewhere: make sure the skin file is in the same directory as your index.html page, and not in the directory with the other flash components.
I´m quite sure that skin-SWF suppose to be inside resources folder, just like it is in your local system...
Make sure you empty your browser´s cache, otherwise the old version may be loaded from there instead of new one.
