Clicktoflash4/9/2023 ![]() I think this is great stuff, but I’m concerned that sites depending on Flash-based ad revenue (note to such sites: use static, non-CPU-hog banners and nobody gets hurt) will change something to defeat this. ZZZClickToFlash wouldn’t work) or is preference given to ist entries before STR# resources? Anyone know?ĬlickToFlash is loaded as WebKit prefers to load WebKit-style plug-ins over Netscape-style plug-ins if both claim a MIME type. When looking for a suitable plugin for a give MIME type, why does WebKit load ClickToFlash instead of Flash Player? Is the namespace collision resolved via “first to load”(e.g. ↶Ĭategories: Documentation Programming Safari/WebKit. Thanks to WebKit developer Mark Rowe for reminding me to look for a resource. * Flash Player doesn’t declare its MIME types in its ist it declares them in a resource file, in ‘STR#’ resource 128. So now that you know how ClickToFlash works, maybe you can help fix its bugs? The script finds itself talking to a wall, and breakage happens. I suspect one reason is that they try to interact with the movie via JavaScript ClickToFlash doesn’t export a script object and wouldn’t be able to communicate with the real Flash Player anyway. ![]() There are several reasons why a site may not work with ClickToFlash. This time, it comes up with only one handler: the real Flash Player plug-in. WebKit notices this change and looks again for a plug-in to handle the movie. When you click on the ClickToFlash view, it modifies the object or embed element that the view represents, changing its type attribute to the other type-the one ClickToFlash doesn’t declare the one no webpages actually use. You will notice that ClickToFlash only declares one of these.Īs it turns out, everybody only uses application/x-shockwave-flash. Adobe’s Flash Player plug-in actually declares * two MIME media types: application/x-shockwave-flash and application/futuresplash. So, in the case of ClickToFlash, it only loads ClickToFlash when it encounters something that is of type application/x-shockwave-flash. It uses these ist dictionaries to know which plug-in it needs to load. WebKit only loads a WebKit plug-in when it first encounters some content that it needs the plug-in for. It does this by way of a dictionary of dictionaries: WebPluginMIMETypes ![]() It does not use the Netscape plug-in API.Ī WebKit plug-in declares a list of MIME media types in its ist bundle. This should help you understand how it fails on some sites, and maybe aid you in contributing to its development.įirst off, it is a WebKit plug-in it’s written in Cocoa and uses WebKit’s own plug-in API. Speaking of everybody’s favorite WebKit plug-in, here’s how it works. ![]()
