What Is RMVB File Extension?

RMVB file extension, short for RealMedia Variable Bitrate, is a variable bitrate extension of the RealMedia multimedia compression format developed by RealNetworks. As opposed to the more common RealMedia container, which holds streaming media encoded at a constant bit rate, RMVB file extension, compared with DVDRIP, is typically used for multimedia content stored locally.Files using this format have the file extension .RMVB.

RealMedia codec uses compression similar to MPEG-4 Part 10 codecs, such as X264. Limited support is available on some media players, generally on the Windows platform, including the proprietary RealPlayer 10 and the open-sourced Media Player Classic, using an appropriate DirectShow filter or Real Alternative. RealPlayer and some other programs such as totem are able to play real video or RMVB files in Linux/UNIX-based x86 machines through the use of WIN32 DLLs or native closed-source libraries. In late-2008, standalone players capable of decoding RMVB files have begun to be available on the market.
