To set JW Player buffer length is easy. It can be configured through Flash variable in JW Player using the bufferlength property.

Variable number is the number of seconds of the file that has to be loaded before starting. Set this to a low value to enable instant-start and to a high value to get less mid-stream buffering. By default, the value is 1.

You can add more than one plugin to a JW player, to install multiple plugins, use comma to separate the plugin names, for instance:

so.addParam(‘flashvars’,'plugins=accessibility,yourlytics-1′)

In the example above, both accessibility and yourlytics-1 plugin will be loaded to the JW Player.

If you have http://www.example1.com/a.swf and the following lines in

Security.allowDomain("*");
Security.loadPolicyFile("http://example2.com/subfolder/crossdomain.xml");

When you try to compile, you will receive the following error:

Error opening URL 'http://example2.com/crossdomain.xml'

This happens due to the fact that there is a security change in Flash player 10. crossdomain.xml can no longer work in sub folder without a crossdomain.xml in root directory.

A root directory must have a crossdomain.xml with the following meta policy for crossdomain.xml in sub folder’s to work.

<cross-domain-policy>
   <site-control permitted-cross-domain-policies="by-content-type"/>
</cross-domain-policy>
