The .flv filename extension and the FLV file format are associated with Adobe System's flash player. It is a container format primarily used for content delivery over the internet and other computer networks. It is an open file format and supports delivery of audio and video streams through players that are compatible with the specification. Flash video, or FLV, has been popularized on the internet by video streaming websites that encode their video in this format. Most web browsers have support for the format through web browser plugins with the exception of Google chrome which has native support for the format.
RealNetworks, an internet streaming Media Company, is credited as the developers and owners of the proprietary RealMedia multimedia container format. The filename extension .rm refers to this format which is used as an audio and video wrapper to distribute digital media content over the internet. The first version of this container was released in 1997 and has been popularized for its ability to unpack the digital stream while it is being downloaded over computer networks such as the internet. The format is platform agnostic and works equally well on Microsoft Windows as it does on Linux or Mac OS.

Upload FLV files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized RM results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent RM audio with dependable progress tracking.
The FLV format is similar to the SWF file format (also owned by Adobe Systems) in the technique used to encode audio and video streams but differs slightly with multi byte storage in big endian byte order. FLV supports a number of codecs including but not limited to On2 VP6 and Sorensen Spark. FLV files can only have a single and synchronized audio and video stream. The format has a header tag followed by alternating blocks of back pointers and tags.
Unlike RealMedia variable bitrate format, the RealMedia container format encodes streaming media at a constant bitrate. .rm files use proprietary video and audio compression encoding formats from the RealVideo and RealAudio suite of compression formats. Video stream encoding was upon its initial release based upon the H.263 compression format.
