Ogg
Ogg is a free, open container format designed for efficient streaming and manipulation of digital multimedia, primarily audio and video. It is maintained by the Xiph.Org Foundation and serves as a wrapper for codecs like Vorbis (audio) and Theora (video), providing features such as multiplexing, metadata, and error resilience. Ogg is widely used for internet streaming, gaming, and open-source media applications due to its patent-free nature.
Developers should learn and use Ogg when building applications that require open, royalty-free multimedia streaming or storage, such as web-based audio/video players, game engines, or open-source software projects. It is particularly valuable for avoiding licensing fees and ensuring compatibility with free software ecosystems, making it ideal for platforms like Linux distributions, streaming services like Icecast, and tools like VLC media player.
