LiveVideoStreaming

LiveVideoStreaming is the delivery of live video content over a network as it is produced, allowing viewers to watch in near real time. It combines capture, processing, and distribution to enable immediate viewing experiences across devices and locations.

A typical pipeline includes capture, encoding/compression, ingest to an encoder or streaming server, transcoding to multiple bitrates, packaging into adaptive bitrate streams, distribution through a content delivery network, and client playback. This flow is designed to adapt to varying network conditions and device capabilities.

Common transport protocols and formats include RTMP for ingest, and HTTP-based protocols such as HLS and MPEG-DASH for delivery, with WebRTC used for ultra-low latency interactions. Video codecs such as H.264/AVC, H.265/HEVC, and AV1, and audio codecs like AAC and Opus, are used.

Latency varies by method: traditional HLS/DASH tends to tens of seconds; WebRTC can achieve sub-second delays; practical latency depends on encoding, network conditions, and CDN configuration.

Applications include live sports, news, entertainment events, gaming streams, conferences, education, and corporate communications. The technology supports broad audiences and various production scales, from small events to large broadcasts.

The ecosystem often includes encoders (software or hardware), streaming servers or cloud-based ingest, ABR packagers, CDNs, and players on various devices. Management tasks cover ingest reliability, real-time monitoring, and compatibility across platforms.

Common challenges are network reliability and bandwidth, scaling to large audiences, video quality adaptation, copyright and DRM, and privacy concerns. Ongoing development seeks lower latency, higher efficiency codecs, and more robust delivery architectures.
