media streams

Media streams enable the real-time capture and transmission of synchronized audio and video data across networks.

Media streams function as the backbone for modern real-time communication by managing synchronized tracks of audio and video data. Through the Media Capture and Streams API, developers access local hardware like cameras and microphones via the getUserMedia method to create a MediaStream object. This technology powers critical low-latency applications (including WebRTC for video conferencing and the Web Audio API for live processing). By breaking data into manageable packets for continuous delivery, media streams eliminate the need for full file downloads, allowing for immediate consumption and interactive experiences in the browser.
