any file format to swf

Is there any opensource/co开发者_开发知识库mmercial software that converts ppt, doc, pdf, video, audio into swf format?

Yes: http://www.swftools.org/ (Open Source)

Makes SWF from PDF, images, video, sound.

To convert from office formats, you will probably need to first convert office files to PDF, and then PDF to SWF. There are many tools to do this, one of the best is OpenOffice in server mode.

An example implementation is Alfresco Share (also Open Source), which uses swftools and OpenOffice to convert all sorts of files to SWF.
