How And When ONVIF Will Support H.265

Author: Ethan Ace, Published on Oct 07, 2016

ONVIF Profile S does not support H.265.

And Profile S is what literally every ONVIF device supports today for video.

So what happens to H.265 cameras?

In this note, we explain ONVIF Media2 service and ONVIF Profile T, how they impact H.265, the tradeoffs of them, and the timetable for support.

Is the Media2 service a sufficient specification for h.265 implementation by two unrelated parties?

Or will Profile T reference other h.265 implementation details, yet to be defined?

Two parties, today, can implement H.265 via Media2. There is just no conformance test for it til Profile T comes. There's nothing else in that profile that enables H.265, aside from Media2.

There are some added features not related to H.265 in Profile T which ONVIF hasn't made public yet, but I expect we'll hear about them in detail maybe around ISC. That would seem far enough down their timeline to actually discuss it.

Implementing H265 is not problem at all. But implementing MediaService2 will be so big headache. I expect a lot of confusion and incompatibilities regarding this new service. It aims to replace old, battle tested MediaService that actually works well. And this means that the whole industry should basically throw away years invested in development and testing, and re-implement very basic functionalities from scratch. MediaService most complicated and most demanded part of Onvif. It's the core of Onvif, almost all functionality depends on it.

I strongly believe that this move was a big mistake. They had an option to extend MediaService without building new, incompatible one.

Mistake for whom exactly? Axis, Sony and Bosch (the founding members of ONVIF) have collectively announced 0 cameras with h.265, (as far as I'm aware).

Can Axis Be Kicked Out Of ONVIF?

Was Creating ONVIF a Wise Decision For Axis?

ONVIF is not about Axis, Sony and Bosch. Full Members and Contributing Members can participate to standard development. Please checkout members list http://www.onvif.org/About/MemberList.aspx. There are 19 Contributing Members and 39 Full Members.

Members can participate, but who decides the very decision you decry?

2, thanks for the feedback. Can you elaborate on that? Will VMSes then have to support both the 'original' MediaService and MediaService2 or does MediaService2 replace / eliminate the 'original' one?

And does MediaService2 only require changes on the VMS side or will cameras have to change to?

Cameras and VMS's are forced to support both MediaService'es. You can't drop original MediaService because that breaks compatibility with legacy products.

Because of implementation of MediaService2 on camera side will be buggy next 3-4 years.VMS manufactures will have hard time guessing which MediaService they better to use to receive mjpeg/h264 or do over stuff with audio or metadata: MediaService2 is likely to be buggy, using original MediaService is risky because it deprecated by standard, and camera manufactures will treat that service accordingly.

#2, if a camera does not support H.265, why would they want or need to support MediaSerivce2? Can't they just continue with the original one? Am I missing something? Thanks.

Update: In Xprotect Device Pack 9.1, Milestone is claiming ONVIF H.265 support. Currently, they say:

So far numerous cameras from Dahua have been tested and verified in this release, with more to come.

We'll be looking into this support to see if other manufacturers work via ONVIF without specific integration, as well.
