I would suggest that both are true.
ONVIF can easily 'support' H.265, but whether VMS companies are able to support that video encapsualtion is at 'best' speculation at this point.
It's likely to listed and advertised by a compliant camera as an optional video CODEC and if the VMS can support it, it will grab that stream. Whether any of them initially do or not...
Not an official envoy of ONVIF but an active contributing member nonetheless.
Like Ian mentioned it's already possible to extend ONVIF to support additional codec types (I personally know of a least one company implementing JPEG2000 through ONVIF.)
ONVIF is also working on making H.265 an official part of its specification as an extension is currently in-preparation for support of H.265 and open approach for future/custom codecs. I do not have the publication timeline for the extension but expect it sooner than later.
Also ONVIF just recently started discussion for a new Profile to cover H.265 and frequently requested missing features like Motion Detection. The work on the new Profile should start in the next ONVIF F2F Meeting happening in early June.
Official ONVIF Response:
As one of our valued contributing members mentions above, The Technical Committees are actively researching methods to add the newer technologies to the core specification. This includes H265 and a look at other market leading trends in technology.
Once added to the core specification a member can propose a new profile that includes this functionality.
Standards work tend to lag a little bit behind the technology curve, but in ONVIF's case it is encouraging that the members are already actively working to create a sepcification and standard that allows manufacturers on the leading edge of technology to continue to leverage the ease of interoperability conformance to an ONVIF profile brings.
Does anyone have any update, or are we headed towards a new dark period of incompatibility?
It's already begun.
"Let's see, its got the latest compression technology and ONVIF version. Check."
"Now let me find a good NVR to go with."
Just summarizing my thoughts for brevity:
On the CODEC side
- Many H.265 cameras are now starting to ship.
- The cameras in question include 4MP models from major manufacturers selling at < $100
- Therefore there is likely to be significant numbers of h.265 units sold in the next year.
- H.265, irrespective of its actual performance is getting a lot of buzz, and people will buy on promises.
- People who buy h.265 with the latest ONVIF may think that their equipment will work with other similar equipment. Sometimes they will be right, sometimes wrong depending on the true manufacturer, which is often hard to determine.
- People WILL be somewhat mollified by the fact the the ONVIF cameras should work under h.264 with other equipment.
- But having been sold on h.265, they are unlikely just to give up without some effort on integrating cameras. Or at least discovering which can work with what.
On the standards process
- 10 months ago ONVIF started 'discussions' on h.265
- ONVIF said it would most likely be a completely new profile
- ONVIF website still brings back no result searching for h.265
- Even a draft spec would help align people in the design stage or v2 stage.
- New Profiles take months to complete and months to implement
- Therefore it is likely > 1 year before ONVIF would help.
I predict it will be the most common technical question that people will ask in a year.
Expecting formal wager from BK...;)
