An HTTP Live Streaming (HLS) developer designs and implements streaming services for real-time media over the internet. They utilize the HLS protocol, developed by Apple, to break down streams into a sequence of small HTTP-based file downloads. Each download carries a short chunk of the overall stream. They ensure seamless media playbacks, creating adaptive bitrate streaming for optimal performance, regardless of network conditions. Moreover, they ensure the stream’s compatibility with various devices and browsers. They also handle aspects like encryption for secure streaming and work on troubleshooting any streaming issues, offering a smooth user experience.
