What is RM?
RM (RealMedia) is a multimedia container format developed by RealNetworks. It was initially designed to stream audio and video content over the internet, and it became popular for online video streaming, especially during the early days of web media. RM files often contain video encoded with RealVideo codecs and audio encoded with RealAudio codecs. Although RM provided relatively efficient streaming for its time, it has become outdated due to limited support on modern platforms and players. As a result, RM files are less commonly used today, especially as more universal formats like MP4 have taken over.
