User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_6; en-us) AppleWebKit/525.27.1 (KHTML, like Gecko) Version/3.2.1 Safari/525.27.1 Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1b2) Gecko/20081201 Firefox/3.1b2 I tried creating a HTML5 page with an embedded video using a "mms://" type URL: <video src="mms://somestreamingserver"></video> Unfortunately, Firefox claims that it needs an external application to open this, even though the QuickTime (or Windows Media player on Windows) browser plug-in can handle this properly using Flip4Mac (Safari does it without a problem). I cannot select the QuickTime plug-in from the list of suggestions that Firefox offers. I also cannot browse to the plug-in on disk and select it (grayed out). I know of no manual way either that I can tell Firefox that it should just use the standard plug-in for this. Is there any workaround for this? Reproducible: Always Steps to Reproduce: 1. Create HTML5 page with <video> tag pointing to an MMS stream 2. Watch as Firefox prompts you for something that you cannot fix Actual Results: It is only possible to play video in an external player. Expected Results: Video should play in the browser. The nightlies of Webkit do this properly.
Plugins can only play mime-types that they report to Firefox. You can see the supported mime-types that each plugin registers to Firefox if you type about:plugins in Firefox. A Plugin can not handle protocols that are not supported by the browser and Firefox only supports file:// , http://, https://, ftp:// . For protocols like mms:// an external application smut be be used. On windows this application can itself register as handler for external protocols in the registry and Firefox opens this application if it encounters such a protocol link. Does the flip4mac plugin contain an external Video Player application ? I know that you can use VLC to play MMS:// Urls on mac.
