swfobject.embedSWF not working?

Question

The following code embedding a Flash animation into an HTML document using SWFObject displays only the alternative content. Why?

Answer 1

Chrome's since version 55 does not initialize the variables that swfobject needs to detect if Flash is installed. You can apply primitive patch to swfobject js to skip hasPlayerVersion check:

-       if (hasPlayerVersion(swfVersionStr)) { // create SWF
+       try {  // create SWF
            var obj = createSWF(att, par, replaceElemIdStr);
            if (att.id == replaceElemIdStr) {
                setVisibility(replaceElemIdStr, true);
            }
            callbackObj.success = true;
            callbackObj.ref = obj;
-       }
-       else if (xiSwfUrlStr && canExpressInstall()) { // show Adobe Express Install
-           att.data = xiSwfUrlStr;
-           showExpressInstall(att, par, replaceElemIdStr, callbackFn);
-           return;
-       }
-       else { // show alternative content
+       } catch (e) {  // show alternative content
            setVisibility(replaceElemIdStr, true);
        }
