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)[reply]

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

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)[reply]

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)[reply]

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)[reply]
