HTTPS Request Optimization Strategies for Mobile Video Streaming

To achieve sub‑second start‑up for mobile video streaming, the iQIYI overseas project applies layered HTTPS optimizations—including DNS and certificate caching, ECDHE/X25519 key exchange, false start, lightweight cipher suites, ECDSA certificates, OCSP stapling, and session‑ID/ticket reuse—while transitioning toward TLS 1.3 0‑RTT and HTTP/3 QUIC for further latency reduction.

CPU Share Syncer: Enabling High‑Priority Task CPU Preemption in iQIYI Video Production Kubernetes Clusters

iQIYI’s cpu‑share‑syncer daemon runs on every node, reads a pod’s iqiyi.com/cpu‑share annotation, updates the pod’s cpu.shares after disabling the Kubernetes CPU CFS quota, and lets high‑priority video‑production pods pre‑empt CPU from lower‑priority pods, significantly speeding task execution.

GAN-based Cold-Start Solution for New Video Recommendation in Short Video Systems

iQIYI’s short‑video team solves the new‑video cold‑start problem by using a GAN that generates latent user features from video attributes and a discriminator to validate them, then matches these vectors to real users via cosine similarity, achieving double‑digit gains in exposure, CTR, and watch time.
