What Tencent Cloud Live Video Streaming is
Tencent Cloud Live Video Streaming (CSS) is a cloud service for live video broadcasts, with options for large-scale playback and ultra-low-latency events. It supports push through RTMP, SRT, WebRTC, and RTMP over SRT, and playback through RTMP, FLV, HLS, and WebRTC. Cloud processing options include transcoding, adaptive bitrate, recording, time shifting, real-time subtitles, screenshots, watermarks, and standby streams. AI features include live translation and subtitles, automatic highlight clips, stream summaries, removal of identified illegal audio and private images, and recognition of highlight areas. CSS can work with Tencent IM products for chat and audience-host co-anchoring. It offers console controls and APIs for live-stream operations, plus integrations including Tencent’s MLVB and Tencent Effect SDKs, OBS, XSplit, and FMLE. Security controls include authentication, IP allowlists and blocklists, and DRM; DRM playback is limited to HLS, with licenses from fee-charging third parties.
