Stream component problem

Installation

Hello,
I’ve got a problem with the stream component. I didn’t notice when exactly it happened to me but now I have a problem with it.
The log file says:

I was trying to cheat and make lower version symlinks to existing libs but at the end it still wants to have exactly required version. Does anyone have an idea how to fix it ? Thank you.

P.S. Version of Home Assistant is 0.101.3

Hey anatolyk, i have the same issue. Did you fix it? Thanks Thomas

You’ll have to have pip compile the av component for you.
Command goes something like this: pip install --no-binary --no-cache-dir --upgrade av

Hi, I experienced the same issue on my Odroid N2+. I needed to first uninstall the av and then install it again.
pip uninstall av
and then run:
pip install av --no-cache-dir --upgrade --no-binary av
Hope that helps someone…
