dashjs

Dash.js is an open-source JavaScript library developed by Bitmovin for adaptive streaming of video and audio over the internet. It is designed to work with the MPEG-DASH (Dynamic Adaptive Streaming over HTTP) standard, which allows for the delivery of media content in a way that adapts to the viewer's network conditions and device capabilities. Dash.js is widely used in web browsers and supports various video and audio codecs, including H.264, H.265, and AAC.

The library is known for its flexibility and extensibility, allowing developers to customize its behavior to suit specific needs. It supports both live and on-demand streaming, and can be integrated into web applications using standard HTML5 video elements. Dash.js also includes features such as adaptive bitrate switching, which automatically adjusts the quality of the stream based on the viewer's network speed, ensuring a smooth viewing experience.

Dash.js is maintained by Bitmovin and has a large community of contributors and users. It is regularly updated with new features and improvements, and is compatible with a wide range of browsers and devices. The library is licensed under the Apache License 2.0, making it freely available for use in both open-source and commercial projects.
