Add "stream" to default_config

[tsbernar]

Proposed change

This last PR (#89969) got locked, and I'm not sure my last comment was seen about the av 8.0.0 release before that happened. Re-opening, and adding the context again here:

We do not try to install the av package on startup when resolving the dependencies of the default config. It seems like this is an artifact from before av used binary wheels and had a more difficult manual installation process. I see that line in default_config/__init__.py was written in 2019, and av was updated in 2020 to use binary wheels so can now be easily installed with pip

Due to the complexity of the dependencies, PyAV is not always the easiest Python package to install from source. Since release 8.0.0 binary wheels are provided on PyPI for Linux, Mac and Windows linked against a modern FFmpeg. You can install these wheels by running:

pip install av

(https://pypi.org/project/av/#description)

It took some digging to figure this out for me when adding a generic camera did not work.

The UI showed "unknown error"; the logs showed that it was because stream was not set up, which was ultimately because av was not installed, and it did not get auto-installed on startup when reading the config.

I think it is safe now to make this change since av 8.0.0 release and stream should get set up correctly including the install of av.

If you would like to keep it this way for a manual install, I could instead update the documentation here:
https://www.home-assistant.io/integrations/stream/

Maybe with a troubleshooting section or a note about installing av manually?

Let me know your thoughts.

I discussed it with some other devs and this change is ok to move on 👍

[allenporter]

Looks like this requires some hassfest updates / update of package_constraints.txt? Otherwise really happy to see stream setup get simpler!

Thanks, everyone!

@MartinHjelmare, which documentation should I be updating for this? The home-assistant.io docs for stream already say

The stream integration is automatically loaded by default_config and enabled by the camera platforms that support it
(https://www.home-assistant.io/integrations/stream/)

which now matches this change

[MartinHjelmare]

@balloob do you want further documentation changes?

[balloob]

oh, looks good indeed.
