Very cool - That's nearly exactly what I need for a research project.

FWIW, there's also the non-free JPEG-XS standard [1] which also claims very low latency [2] and might be a safer choice for commercial projects, given that there is a patent pool around it.

JPEG-XS is great for low latency, but it uses more bandwidth. We're using it for low-latency image streaming for film/TV post production:

We currently use the IntoPIX CUDA encoder/decoder implementation, and SRT for the low-level transport.

You can definitely achieve end-to-end latencies <16ms over decent networks.

We have customers deploying their machines in data centres and using them in their post-production facilities in the centre of town, usually over a 10GbE link. But I've had others using 1GbE links between countries, running at higher compression ratios.

A patent pool doesn't make you safer: it's just a patent troll charging you to cross the bridge. They are not offering insurance against more patent trolls blackmailing you after you cross the bridge.

While I am personally opposed to software patents, I'd argue that the JPEG XS patent holders [1] are not 'patent trolls' in any meaningful sense of the word.

While I have no personal experience on that topic, I'd assume that a codec with a patent pool is a safer bet for a commercial project. Key aspects being protected by patents makes it less likely that some random patent troll or competitor extorts you with some nonsense patent. Also, using e.g., JPEG XS instead of e.g., pyrowave also ensures that you won't be extorted by the JPEG XS patent holders.

One may call this a protection racket - but under the current system, it may make economical sense to pay for a license instead of risking expensive law suits.

		>Key aspects being protected by patents makes it less likely that some random patent troll or competitor extorts you with some nonsense patent Does it? how? Patents can overlap, for example. Unless there's some indemnity or insurance for fighting patent lawsuits as part of the pool, it's a protection only against those patent holders, not other trolls.
