Is it too bad if I did not understand any of this: "Also you might need
"mm-accel" versions of gstreamer components, which are used when "mmip"
flag in MACHINE_FEATURES is set..."?

I included the meta-arago-extras layer, ran "bitbake-layers show-recipes"
and got this error:

Parsing recipes..ERROR: ExpansionError during parsing

bb.BBHandledException

I do not know how to address this error. I tried rolling back to a previous
Yocto version, from Daisy to Dora, but got the same error.

I will write to the meta-arago mailing list too. Thanks for the pointer.
