You've been made heavy change in script and due to this service script at part


ExecStart=/home/pi/hls.sh 103 &

couldn't be started - 103 is the number of channel wich we want to record but in script there is no $1 variable (as the first parameter of script)

then why


-i http://10.0.0.11:9981/stream/channelnumber/2 \

maby you forget variabes $1

-i http://10.0.0.11:9981/stream/channelnumber/$1 \

see repo

The user heavly changed script, that's what I'm talking about.

That's whay I ask a question to user#25107 where "103" come in his logic.
Seting a hardlink will not use variables.

Brad T

Honestly, I had no idea what the 103 did in the script originally, but even when I remove it I still have the same issue. If I setup the script as intended where $1 represents the channel number, the result is the same too.

Saen Acro

$1 is variable with represent103 in this case

103 is number of channel in tvh in example.

But you can skip it by set url to channel taking it from playlist of tvh
(http://user:pass@host.or.ip:9981/playlist/auth/channels)

Dimitar Maznekov

Saentist reminds me - @Brad T did you have anonimouse local access setup in your TVH? Couse the script assume to have it.
Could you run


/home/pi/hls.sh 103

and put the result here

little corrections

user with pasword and access fron 127.0.0.1 or local network ex. 192.168.0.0/24

also is location where hls chunk is written are in web server folder
ex "
https://acme.com/software/thttpd/logos/thttpd_powered_1.gif
":https://acme.com/software/thttpd/

Dimitar Maznekov

Yes just test it. Without anonymous user script wont work.
You should have user setup like

user#11052 can you update first post to contain more concentrated information for this HOW-TO

P.S. do not delete content just add new on top with separation "new line, ---, new line"
link to github repo if you wish

Brad T

I added an anonymous user, but the service still won't start. Everything still works manually though.

you not fallow steps to make it work:
1. if there's public access to TVH limit ip access to IP range for "*" user
2. make choice if you will use channel number or channel url
3. see logs or test via FFPROBE

Brad T

Okay, I changed the range.

I am using the direct url

The service looks like:

This is what happens when I check the service on boot:

Something I noticed while watching the TVH log is that on boot I never see a connection attempt.

Are there any other logs I should provide, and if so, how do I provide them?

Saen Acro

Seems as ownership problem.

Dimitar Maznekov

@Brad T your service file should be corrected:

ExecStart=/opt/hls/hls.sh&

ExecStop =/bin/rm -rf /opt/hls/tmp

If you can start/status/stop it then enabled it at boot with
systemctl enable tv3
That's all

Brad T

It appears the problem was that Debian / Raspbian systemd doesn't properly support After=, I solved this by doing RestartSec=5s. Everything works now.

I'm not so sure that was the problem: https://www.raspberrypi.org/documentation/linux/usage/systemd.md
