Free download and free virus program wmv to mp4, mp4 to wmv
Is there a program where I can download it without virus and convert the wmv files to mp4 files and mp4 files to wmv files and also convert flv files into mp3 files? Please and thanks.


 * Probably many, but FFmpeg is the authentic swiss army knife for such transcoding. --Tagishsimon (talk) 01:14, 25 April 2015 (UTC)


 * Downloadhelper (Firefox AddOn)? -- Hans Haase (有问题吗) 08:44, 25 April 2015 (UTC)

Thanks but those don't help. They are annoying. Anything else?


 * Your identification (signature) is required, as well as the software type (one using the internet or on using the desktop without using the internet) -- Mr. Prophet (talk) 18:40, 27 April 2015 (UTC)

Is there any difference between native support for a feature and a feature being built-in?
When someone says that PHP has no Unicode native support, or that Erlang has native support for concurrency, does it just mean whether it's integrated or built-in the language or not at all? What if a functionality can only be used after importing a library, is that native support or built-in? --Senteni (talk) 22:53, 25 April 2015 (UTC)


 * Yeah - generally if something is "native" then it works in the base language - if it's not native, then you probably need a library (or maybe you have to write it yourself, or maybe it's just impossible). SteveBaker (talk) 05:38, 29 April 2015 (UTC)
