- Description
- RealPlayer created RA for audio streaming. It makes use of various audio codecs from those that deliver high-fidelity sounds to those that record low bitrate audio data. Radio stations mainly used it for online streaming, but current formats have overthrown it.
- WebVTT (Web Video Text Tracks) is a text file format that is used to store subtitles and captions for online video content. It is supported by many web browsers and can be used to add captions and subtitles to HTML5 videos.
