Hi everyone!
I can’t connect to my TV, as well as with Nixos package than Flatpak one.
Here my output:

According to this, I should have some codecs but:
[eyome@nixos:~]$ gst-inspect-1.0 | grep -E "openh264enc|x264enc|vaapih264enc|openh264dec|avdec_h264|vaapih264dec"
It looks like I have none whereas I installed x264 and openh264.
Does someone have any idea?
