Stream component does not work

remo.78 · September 18, 2019, 3:44am

Hello.
I have problems with the stream component. I have never used it and want to configure it. I include this component in the configuration file. I do a configuration check.
I have such an error:

“Configuration invalid
Component error: stream - Requirements for stream not found: [‘av == 6.1.2’]”.

The ffmpeg component is installed. The cameras are work:

$ ffmpeg -i INPUT -an -f null -

In the log the following error:

Help me please, what else can I do to make the component work?

You seem to only have python 2.7 not python 3.6 or higher.

I executed the command

 $ python --version
Python 2.7.16

My configuration:
System Health
arch - armv7
dev - false
docker - false
hassio - false
os name - Linux
python version - 3.7.3
version - 0.98.5
virtualenv - true

list all available python versions:

~ $ ls /usr/bin/python*
/usr/bin/python            /usr/bin/python3.7          /usr/bin/python3m
/usr/bin/python2           /usr/bin/python3.7-config   /usr/bin/python3m-config
/usr/bin/python2.7         /usr/bin/python3.7m         /usr/bin/python3-pasteurize
/usr/bin/python2.7-config  /usr/bin/python3.7m-config  /usr/bin/python3-pbr
/usr/bin/python2-config    /usr/bin/python3-config     /usr/bin/python-config
/usr/bin/python3           /usr/bin/python3-futurize

I removed Python 2 from alternatives and switched preferred Python versions.

~ $ sudo update-alternatives --remove python /usr/bin/python2.7
pi@raspberrypi:~ $ sudo update-alternatives --config python
There is 1 choice for the alternative python (providing /usr/bin/python).

  Selection    Path                Priority   Status
------------------------------------------------------------
  0            /usr/bin/python3.7   1         auto mode
* 1            /usr/bin/python3.7   1         manual mode

Nothing changed. Same result.

Component error: stream - Requirements for stream not found: ['av==6.1.2'].

I executed the following command, and that’s what I got:

(homeassistant) homeassistant@raspberrypi:/home/pi $ pip3 install --upgrade av==6.1.2
