You're definitely in a wrong way if you're trying to do it using ffmpeg. 
There are many flash tools which can create such simple SWF files like 
yours. See for example www.flashdig.com Converting your JPEG into a video 
(your SWF now contains a one-frame video stream) you lose a lot of its 
quality (look at the file size!). There is also free SWF SDK, which lets 
create a small software utilities, which can perform such simple operations 
like JPEG=>SWF conversion.

Your "white screen" effect is a sort of bug either in ffmpeg or in the flash 
plugin, which occures when the video stream contains only one frame.

HTH!
