hevc & nvenc

[Petro O. Bochan]

Hello, in Oct 2022 Chrome browser has enabled hevc natively across all platforms hence this codec is now becoming ubiquitous. It is also supported natively on iOS/Android. Does WCS have any plans on enabling hevc as well as nvenc natively?
Thanks,
P

Good day.
There is the ticket WCS-3106 to support H265, but Chrome still does not support publishing, but playback only. So we plan to implement H265 support for RTSP streams capture first.
Also, seems like Chrome 108 on Windows only plays the test videos from this page https://test-videos.co.uk/bigbuckbunny/mp4-h265. Chrome on Ubuntu 22.04 still can't play them. So the feature seems to be not a high priority yet.

I was thinking about hls/ll-hls on the first place as a playback codec. Also, any roadmap on incorporating nvenc natively?

We already working on NVIDIA GPU transcoding, it is on beta testing stage. There is the ticket WCS-3652 to prepare it for production, but we can't provide ETA yet.

Awaiting nvenc like nothing else, esp for mixer. Mixer is very cool but as soon as you add 4K video to it - the CPU becomes unusable.

Good day.
Since build 5.2.1579 it is possible to capture RTSP stream published by camera as H265: Capturing H265 RTSP stream
Also, H265 MPEG-TS stream may be published: H265 publishing
Note that H265 requires transcoding to play it as WebRTC. Chrome does not play H265 via WebRTC, only from media files and only if client operating system supports this codec.
