Backed by Tencent's well-established audiovisual platforms, globally-deployed cache nodes and leading AI technologies in audio and video, Tencent Cloud Streaming Services (CSS) provides developers with an end-to-end one-stop live audio and video broadcasting solution, including services such as professional and stable live push, transcoding, distribution and playback that fully meet your requirements for ultra-low latency, ultra-high image quality and ultra-high performance to sustain massive volumes of concurrent requests.

Comprehensive Functionality

CSS has a complete set of features such as beauty filters, audio processing, instant broadcasting on the splash screen, low lag, live screencap broadcasting and seamless video definition changing. It is adaptive to various types of terminals and features self-adaptive uplink bit rate, meeting the needs of different application scenarios. It supports playback on any platform, making it easy for customized development.

Global Acceleration

Tencent Cloud boasts 1,100+ CDN cache nodes deployed with China Telecom, China Unicom and China Mobile and over a dozen small and medium ISPs across China such as Great Wall Broadband Network. It has 200+ global cache nodes in more than 50 countries across North America, Europe and Southeast Asia, supporting the global acceleration of live broadcasting businesses.

Professional Video Processing

CSS provides cloud-based transcoding and audio and video processing services for massive amounts of multimedia data. It can transcode audio and video files into formats suitable for playback through OTT and on PCs or mobile devices, and can perform various operations such as cover screenshotting, editing, porn detection and encryption.

Security Protection

Leveraging a variety of live broadcasting encryption technologies such as referer-based blocklist/allowlist, HTTPS-based secure acceleration and URL encryption, CSS can achieve comprehensive detection and protection to eliminate piracy. Plus, it features a more specialized digital rights management (DRM) solution to fully protect the security of your video assets.

Intelligent Learning

Empowered by AI-based smart recognition technology, CSS can intelligently learn and analyze the content, color and scene of images or videos, allowing machines to recognize and audit them in place of humans and thereby implementing features such as speech recognition, advertisement recognition, intelligent porn detection, intelligent subtitling and meaningless scene recognition.

Statistical Analysis

Based on big data analysis and meeting the needs of different scenarios of various industries, CSS enables the real-time control of push quality and the identification of playback issues. It monitors metrics such as bandwidth, traffic, requests and concurrent connections in real time and provides detailed statistical results to help with business expansion.

On-cloud Recording

CSS can record a user's entire live streaming session as an on-demand video for playback.

Screencapture & Porn Detection

CSS uses screencapture and image recognition enabled by machine learning to detect pornographic content in live streaming sessions.

Auto-Spliced Recording

If a push is interrupted due to exceptions and resumed within a specified amount of time, the recording task will resume rather than restart. After the push is completed (not resumed within the specified amount of time), the system will generate a complete recording file instead of multiple segments.

Live Streaming Time Shifting

During a live stream, users can play back content generated in the past for a combination of live streaming and on-demand contents.
