Evaluation of dash.js Version 5: Performance, Features, and Improvements

dash.js is an open-source JavaScript library that enables adaptive bitrate (ABR) streaming over HTTP based on the MPEG-DASH (Dynamic Adaptive Streaming over HTTP) standard. Its wide adoption in modern web applications, video services, and media players is driven by its ability to provide seamless video playback, even
under fluctuating network conditions. With the work on version 5, dash.js continues to evolve, incorporating new throughput calculation methods, performance enhancements, and bug fixes aimed at improving the overall user experience.
