Yes. But if you want to save the video file on your computer ?

I think examining the media files will cause too much problems : - Making an algorithm to parse the media header to retrieve the metadata (depending on the codec used the header can have a variable size — just presuming) - For the media provider it will consume some brandwith which is the most expensive charge (at this moment) - I think parsing a media file cost more computer resources than parsing an HTML document - Need a soft to edit the data (OK, you definetly need a soft to encode... But if you made a mistake editing some HTML attributes/ elements is lighter than opening the media in a soft, editing it and uploading it again) > What if I actually have a single video (no audio) and multiple audio > files, each in a different language. > Could I somehow sync the video and selected audio file by having > them start playing simultaneously? I think this is possible using the JS API. And this touch the behavior, so couldn't be HTML attributes. -- Nicolas LE GALL http://blog.neovov.com FOAF : http://blog.neovov.com/foaf.rdf
