Si v4l2rtspserver ne fonctionne pas avec vous non plus, voici une alternative old-school basée sur ‘Motion’

apt install motion

User=motion
#EnvironmentFile=-/etc/default/motion
# The the sleep on the following line is needed with systemd version
# 232, otherwise the error message that we echo doesn't hit 'systemctl
# status'.
ExecStart=/bin/sh -c 'exec /usr/bin/motion -n'
Type=simple
# Set StandardError=journal to use journald to log messages from motion.
# See also the "log_file" config file option in motion(1) and
# systemd.service(5).
StandardError=null
ExecReload=@KILL@ -HUP $MAINPID
Restart=on-failure
RestartSec=5
# Don't restart if unconfigured / misconfigured e.g. daemon disabled
# in defaults file. See also /usr/include/sysexits.h or sysexits(3)
RestartPreventExitStatus=78
# To tune restart behaviour, see systemd.unit(5) and use
# "systemctl edit motion" to change the following settings:
#StartLimitBurst=
#StartLimitIntervalSec=
#StartLimitAction=
#FailureAction=
# The following can be used to increase the security of the
# installation, by mitigating risk from attacks on motion and the
# binaries, libraries and scripts which it relies on. They are disabled
# by default in case they break existing installations, e.g. those which
# call site-local scripts which would inherit the same restrictions.
#
# See systemd.exec(5) and
# http://0pointer.net/public/systemd-nluug-2014.pdf for more details
# of these and other related options.
#
# Use "systemctl edit motion" to change these settings.
