Track: WebRTC and Real-Time Applications |
Real-Time Av1: the dawn of High-Quality, secure, self-adaptive Video in WebRTC. |
For a very long time, WebRTC has mainly been used in the Video conferencing industry and for p2p applications. It was missing some of the features the streaming industry had become accustomed to: ABR, high-resolution (4k@60fps, HDR, 4:4:4 chroma sampling, 12bits colors, no bandwidth limit. In comparison, the implementation of the webrtc protocol in browsers, which was used as a base for comparison was limited to 2 Mbps per stream, leading to compromises on quality: 1080p@30, 4:2:0, 8bits colors. ABR was not available, DRM or content protection was not available, and so on and so for. This talk will show how real-time AV1 is bridging the gap with usual streaming while keeping the real-time latency profile. ABR 2.0, E2EE for finer granularity DRM, 4k 4:4:4 HDR 10bits streams encodable in real-time on commodity consumer-grade PCs and laptop, everything will be presented, and comparison with other codecs all run in the same condition (i.e.) real-time mode over RTP media transport, will be provided, answering the usual questions: how much bandwidth can I save for same-resolution/same-quality? How much more taxing is the encoding compared to VP9, H264 software, and H264 Hardware? Finally an update on the status of HW support for AV1 will be presented. |
