New modules PyTurboJPEG and ha-av installed on first HA core start

Installation
1

Since one of the recent releases, the first start of the HA core process installs a lot more and “heavier” Python modules than before, notably PyTurboJPEG and ha-av, which pull in g++ and the whole set of FFmpeg A/V library headers as (new) dependencies and significantly increase the time until the web interface is finally reachable.

Does someone know why those are now installed even that no video/audio features/integrations are installed yet?

According to the requirements_all.txt:

# homeassistant.components.camera
# homeassistant.components.stream
PyTurboJPEG==1.6.7

# homeassistant.components.generic
# homeassistant.components.stream
ha-av==10.0.0

homeassistant.components.generic sounds like it was always used, but it switched to ha-av already with 2022.07 an I’m pretty sure that libavdevice-dev etc were not required yet last year.

Is there probably a chance to move some dependencies to be installed on demand when actual media-related integrations are installed and keep HA core itself slim and easier/faster to install?

ha-av==10.0.0 has pre-built wheels for many archs - see ha-av · PyPI

Not sure what you are running on?

3

No armv7l and armv6l wheels, like common on PyPI, and piwheels does not support Python 3.10 and Python 3.11 yet.

The beauty of the other 3 install methods I guess :slight_smile:

5

Sure, but they have their own limitations are are not always suitable (I do not want to discuss this here :wink:).

So my question is not so much whether there are pre-compiled wheels available in the one or the other way, but whether these modules are really needed already for the bare HA web interface now, without having any A/V related integration installed.

It is a long time since I used core, but it does seem silly to drag in requirements that you aren’t going to use.

Hence I thought it may be a mistake/bug. If not, then I guess only a tiny function of each library is now used by the core and it may be at least worth it to reconsider whether it makes sense to pull in a huge dependency for a tiny use.
