With the popularity of B/S architecture video playback, more and more IoT projects have adopted B/S architecture, and recent versions of Chrome also support H265 decoding technology. The H5S video platform also supports H265 decoding technology. Refer to the "Real-time Video -> RTC WS Playback Mode Switching" section of the H5S video platform manual.

However, the H265 decoding technology is not yet available in WebRTC. If you want to achieve a delay of 300ms on the client side, you can only use WebRTC technology at present. In recent years, the video surveillance industry has made extensive use of H265 video streams. The current practice is to convert H265 to H264,But this will lose image quality.

  With the popularization of AV1 technology, most PCs and mobile phones support AV1 hardware decoding, and Web protocol stacks also support AV1 hardware transcoding. Therefore, Zero Vision Technology has launched a TAV1 hardware transcoding card to support H265 to AV1 transcoding. The delay (8ms) caused by the hardware transcoding card can be basically ignored. This technology can achieve low-latency browser native video playback while preserving the quality of H265 video on the B-side.
