Youtube flash detection

"canPlayV9Swf" is defined in base_all_with_bidi-vfl87002.js, but it's scrambled. The browser knows the pretty-print version:

Code:

canPlayV9Swf = function () {
    var a = j.deconcept, b = a.SWFObjectUtil.getPlayerVersion();
    if (b.major < 9) {
        return g;
    }
    if (navigator.userAgent[v]("Sony/COM2") > -1) {
        var c = new (a.PlayerVersion)([9, 1, 58]);
        if (!b.versionIsValid(c)) {
            return g;
        }
    }
    return i;
};

I didn't see the assignments for "i" and "g", but former is "success" and latter "fail". "Success" if Flash is installed *and* v9 or better.
