# Strobe Flash Player error "ArgumentError – Invalid parameter passed to method"

 * Strobe (flash) results in black videoframe with the following error: “ArgumentError–
   Invalid parameter passed to method.”
 * Tested on Mac Chrome, Mac Firefox, PC Chrome, PC Firefox, additionally on 3 more
   PCs. All systems running up to date browsers and flashplayer.
 * The plugin is incorrectly encoding/rendering the “flashvars” param ‘value’.
 * IE.
    ‘Value’ is encoded as: “<param name=”flashvars” value=”src=http%3A%2F%2Fdomainname.
   com%2Fwp-content%2Fuploads%2Fvw_video share%2F1%2F …etc” RATHER THAN: “<param
   name=”flashvars” value=”src=http://domainname.com/wp-content/uploads/vw_videoshare/
   1/ …etc”
 * Replacing line 2019 in the plugin’s php with $flashvars =’src=’ .urlencode($videoURL).‘&
   autoPlay=false’; (removed posterVar) and adding urldecode to line 2030 ( <param
   name=”flashvars” value=”‘ .urldecode($flashvars) . ‘” /> corrects the url encoding
   issue and the error resulting from the poster var.
 * However poster / static screenshot does not display of course (removed) as I’ve
   been unable to troubleshoot why strobe isn’t displaying it correctly and returning
   an error instead – note that the syntax does look correct to me when urldecoded.
 * VOD support has outright refused to assist me with debugging this problem, clearly
   evident on their online demo, and is instead asking me to pay them for hosting
   or to have a “technician” review my install – Please note however this is a widespread
   issue with v1.4.11 of the plugin and NOT my installation or configuration, something
   that VOD support seems to continue to ignore.
 * I love the plugin, I think the devs are doing great work, however the support
   agents are driving me away from this plugin very fast.
 * If any other users or devs can assist me with this issue, it would be greatly
   appreciated – currently the flashvars param value string “&poster=http://…..”
   is resulting in the error. Removing it (after completing the above outlined “
   urldecode” fix) results in a working video with no screenshot/poster of course.
 * Thanks to all!
