Visionular compares its Aurora1 AV1 encoder against x264 (H.264) for real-time communications (RTC) and WebRTC-oriented use cases, emphasizing screen content coding (SCC) and temporal scalability. The article reports internal test results claiming large BD-rate bitrate reductions versus x264 for 1080p screen content at real-time speeds on CPU, and additional comparisons for camera content on a PC CPU and for low-resolution mobile encoding on a Snapdragon 845 versus x264 and libvpx-VP9.
RTC has been the last major holdout where “AV1 is great, but too slow” kept H.264 and VP8 entrenched—especially for CPU-bound endpoints and strict latency budgets. If Visionular’s numbers translate outside a vendor test harness, AV1 becomes a cost lever for conferencing and collaboration: lower bitrates mean less network pain, fewer resolution drops, and more predictable QoE at scale. The strategic meme: AV1’s real wedge may not be OTT VOD—it’s screen sharing and WebRTC, where SCC plus temporal scalability can turn bandwidth savings directly into meeting quality and platform differentiation.
