Unlocking the Future of Audio‑Video: Key Takeaways from Tencent’s Cloud+ Tech Salon

Event Overview

On April 21, Tencent Cloud+ Community held a hands‑on salon in Beijing titled “Audio‑Video Technology Development Practice”. Over 200 developers attended, and the agenda covered industry trends, product panoramas, QoE optimization, material legality, and mini‑program audio‑video use cases.

Video Cloud Product Panorama

Senior product manager Wang Qi presented the five‑core offerings of Tencent Video Cloud: Video on Demand (supporting UGC, copyrighted, self‑media, and live‑recorded content), Live Streaming, Real‑time Audio‑Video, Short Video, and Video + AI. The platform provides transcoding, accelerated distribution, multi‑screen adaptation, and a super player. More than 80 % of the top‑100 live platforms already use Tencent’s services, and “Live +” (including Live + VR) is identified as a major trend.

H5 Two‑Way Audio‑Video (T‑H5) and QoE Optimization

Based on a decade of QQ audio‑video experience, Tencent Cloud combined TBS WebRTC capabilities with its real‑time audio‑video SDK to deliver high‑quality video calls across multiple platforms via an H5 page. The QoE optimization framework addresses bandwidth estimation, congestion control, packet‑loss resilience, delay reduction, and jitter mitigation. Tools for traceability and rapid issue identification were also demonstrated.

Material Legality on the Video Cloud Platform

OnVideo CTO Liu Qi described the challenges of UGC material legality and outlined a workflow that includes cloud‑based material aggregation, clipping, multi‑platform publishing, ultra‑HD generation, and global node deployment. AI‑driven content recognition is used to verify compliance, while Tencent’s “Ming‑Mou” ultra‑clear processing enhances image quality.

Mini‑Program Audio‑Video Scenarios and Implementation

Product manager Dong Yi highlighted the growing demand for real‑time audio‑video in WeChat mini‑programs, noting difficulties such as noise cancellation, echo suppression, QoS flow control, and packet‑loss recovery. Tencent provides a packaged SDK and cloud services that abstract these complexities, enabling rapid development. Specific industry applications in finance, public security, and education were presented.

Technical Deep‑Dive and Future Outlook

Technical director Chang Qing explained the evolution from basic live streaming to multi‑party video, the principles of upstream and downstream transmission, and the interoperability between mini‑programs and WebRTC. He emphasized the market potential and outlined a quick‑start solution for developers.
