PVR IPTV Simple Client Comand Line start/stop

[dvv06]

I am ashamed, but I do not know where to write this script

I use supervisor to start and control the restart in case of acestream crash.
https://www.digitalocean.com/community/tutorials/how-to-install-and-manage-supervisor-on-ubuntu-and-debian-vps
1. apt-get install supervisor
2. Created myacestream.conf file with the following contents:
[program:myacestream]
command = /home/xbian/acestream.engine/acestream.start
stdout_logfile = /var/log/acestream.log
stderr_logfile = /var/log/acestream.log
startsecs = 10
autostart = true
autorestart = true
3. and put along the way /etc/supervisor/conf.d/
4. reboot RPi3B+
the work is very stable, but after the start of AceStream you have to go into the settings of the IPTV IPTV Simple client disabled and enabled, only then the channels appear in the playlist

my screensaver is disabled
----------------------------------
there is another nuance that is not convenient when using TVset
When I watch cable TV on the TVset, after about 10 minutes the TV screen switches to HDMI from RPi3B+ (XBian).
Therefore, I changed it in the settings (config.txt):
hdmi_force_hotplug=0
hdmi_ignore_hotplug=0
hdmi_ignore_cec_init=1
hdmi_ignore_cec=0
, but now if you watch TVset and turn on the raspberry, it is impossible to switch to HDMI (the Xbian screen appears with the message "connection ...") and there is no way to control, because the connection did not succeed
It is connected only then you turn on the raspberry with the HDMI source previously switched in the TV settings
