RealMedia (RM) is a multimedia container format that is proprietary to RealNetworks. RealNetworks designed RM to stream content over the Internet. RM compresses video with a RealVideo codec and audio with a RealAudio codec.
As a proprietary format, an RM file opens by default in RealPlayer, which RealNetworks developed. If RealPlayer is missing, then download it here.
Other programs that can open an RM file include VLC media player, MPlayer, and CrystalPlayer. For mobile, on Apple iOS, try OPlayer HD, and VLC media player for Android.

WebM (WEBM) is a freely-licensed file container designed for the Web. Specifically, it was designed to be compatible with HTML5, originally. It supports chapters, captions, subtitles, metadata tags, streaming, attachments, 3D codecs, 3D containers, and hardware players. WEBM compresses video streams with VP8 or VP9 codecs, and audio with Vorbis or Opus codecs.
VLC media player and MPlayer can open WEBM files on any operating system (OS). Other good choices for opening WEBM include Winamp for Microsoft Windows OS, and Elmedia for Mac OS X.
Microsoft browsers do not have built-in WebM codecs. Therefore, install the codecs separately. However, most browsers support WEBM files.
