SOLVED: Codec issues on Sony Bravia using hardware acceleration

[Mehdi_FR]

I see. But, the getent command does not work on my terminal (I use MacOS Terminal).
So I asked ChatGPT for an alternative.

Please see the history of commands :

-------

XXXXX@Serveur_Mehdi$ getent group render
-sh: getent: command not found
XXXXX@Serveur_Mehdi$ cat /etc/group | grep render
XXXXX@Serveur_Mehdi$ cat /etc/group | grep render
XXXXX@Serveur_Mehdi$ cat /etc/group

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

you can see there was no render group initially before I create one.

Why do you recommend ?
thank you for your time and reactivity. I really appreciate
