If the webpage is served over HTTP and the SWF is served over HTTPS, then jPlayer does not function. We need to call flash.system.Security.allowInsecureDomain("*") in order to fix it.
Use allowInsecureDomain in order to support serving the SWF over HTTPS.
I will add this rule to the SWF. Thanks.
Merged insecure domain rule #130 by @prekageo
