Hello, I am currently working with a bunch of SWFs generated by Sothink’s Flash Movie Encoder software (I am not the one that encodes them, another company does). I currently have a PHP page that cycles through a series of these SWF movies on 30 second intervals. These SWFs do not have any playback controls. I have a small HTML button that essentially refreshes the page and toggles a SESSION variable declared for sound on or sound off (so that it doesn’t annoy the surfer). However, I do not know how to actually make the Flash SWF mute initially based on this variable. Is there a flash param that allows me to control the SWF volume? I know how to do this if I were to do it in flash, but because the files I’m working with are already pre-encoded by the software, I cannot tamper with these files and must find this alternative to muting the movies. Is there any way? Thanks.:toad:
