RealMedia Variable Bitrate (RMVB) is a variable bitrate extension of the RealMedia multimedia container format developed by RealNetworks.
As opposed to the more common RealMedia container, which holds streaming media encoded at a constant bit rate, RMVB is typically used for multimedia content stored locally. Files using this format have the file extension “.rmvb”.
RealMedia uses compression similar to MPEG-4 Part 10 codecs, such as x264.
RMVB files are extremely popular for distributing Asian content, especially Chinese television episodes and movies.[2] For this reason, they have become noticeably present (though not entirely popular) on file sharing platforms such as BitTorrent, eDonkey and Gnutella.[citation needed]
On the Windows platform, the proprietary RealPlayer SP and the open-sourced Media Player Classic support RMVB, using an appropriate DirectShow filter or Real Alternative. On Linux/UNIX platforms, MPlayer, xine, and Totem are able to play RMVB files using the open-source, reverse-engineered RMVB implementation in FFmpeg. The format is also supported for playback by the cross-platform VLC media player.
