KMS 7 kurento-client problem

[Neil Young]

As known with KMS 7 there are some changes in very old JS events https://doc-kurento.readthedocs.io/en/latest/project/relnotes/v6_18_0.html#deprecated-opencv-extra-modules

Installed KMS 7 now into a focal docker. Wondering what "kurento-client" to use.

npm i kurento-client 

installs  "kurento-client": "^6.16.0"

but this client isn't aware of the changes like "IceComponentStateChanged" (and others)

How to address this?

I would also be fine with a 6.18, but this can't be installed on focal, right?

[Neil Young]

Anybody?

[Juan Navarro]

The way to address this, given that 6.18 is in pre-release stage (aka in development) is to use the development version of the client:

https://doc-kurento.readthedocs.io/en/latest/user/installation_dev.html#kurento-javascript-client

this way you'll get a client version that is able to communicate with both Kurento <= 6.18 and 7.0 at the same time.

Kurento 6.18, i.e. the nightly dev packages, cannot be installed in Focal, because Kurento 6.x is only built and tested for Ubuntu 16.04 and 18.04. Although you can always use the Docker images, which are handy because they can run anywhere Docker runs, regardless of needs of Kurento, as you did.

Note there is already a 7.0 Docker image for use:

kurento/kurento-media-server:dev-7.0.0

Which is essentially the same thing as yours (Ubuntu 20.04 with apt-get install kurento-media-server)

Thanks. That’s what I was looking for.

But it doesn't work for me. Getting strange error, which might be on my side, but couldn't find a fix for it. npm clean cache --force didn't work

Sorry, my bad. Was using the wrong entry (bower!)

"kurento-client": "git+https://github.com/Kurento/kurento-client-js.git#master"

works
