Piccap autstart does not work about piccap HOT 29 CLOSED

I investigated a workaround to autostart the capture service without rebooting the tv or disabling the quick start. I used home assistant to turn off and on the capture service once the tv turned on. If someone is interested in it .. Don't know if this is the right place for this.

yes i am interested in can you post it ?

1. Enable SSH access on your tv.
2. Place your public key on your tv for connecting via ssh without password
3. Create the following script in /home/root on your tv:

root@LGwebOSTV:~# cat my-piccap-service.sh
#!/bin/bash

set -e
luna-send -d -n 1 "luna://org.webosbrew.piccap.service/$1" "{ \"method\": \"$1\"}" &

4. Create a shell command in home assistant (configuration.yaml). You have to change the path to your private key (im using docker and had to mount my key in the home assistant container):

shell_command:
  piccap_capture_service: 'ssh -i "/config/.ssh/id_rsa" -o "StrictHostKeyChecking=no" root@<your-tv-ip> "bash my-piccap-service.sh {{ command }}"'

5. Create an automation which triggers when your tv turns on:

- service: shell_command.piccap_capture_service
  data:
    command: stop
- delay:
    hours: 0
    minutes: 0
    seconds: 5
    milliseconds: 0
- service: shell_command.piccap_capture_service
  data:
    command: start

I don't know if its necessary to stop the service first. But it works. And I dont know why the luna command has to be launched as a background service (&). But without the command gets not executed.

@TBSniller thank you. issues opened here ->
#webosbrew/hyperion-webos#95

for everyone who has the same issue. I know that there are at least 2 ppl with the same issue

from piccap.

I have exactly the same problem

from piccap.

I assume both of you are using libdile_vt?

Have you used some older piccap version? If so, then please try running rm /var/lib/webosbrew/init.d/piccapautostart, then go to piccap settings, disable autostart, save, reenable autostart, save... I think we still have a minor bug in autostart handling which fails when some old piccap version (before 0.2.x) was installed before and left some files on the filesystem.

yes i had 2 older versions of picap on my lg. I will test this and come backk

from piccap.

did that, but for me it seems not to fix the issue.
Autostart seems to working, but not connecting to the hyperion server. via manual start it works.
how can i deinstall completely and install again?

it looks like it does not load a config, only when manual restart then it does... at least this describes my issue

from piccap.

Do you guys have some more information for us?
Which settings are you using?

in which format is your ssh key ? i got following error:

That's a good summary.

okay its working thank you 👍

Hello,

i have also the problem that the autostart doesn't work. If i open piccap manuel, than it works.
Setting is new 2020+ tv / video capture / graphic capture.
I think it worked until there was a update from the tv. but root is still ok says webosbrew.
Can I just root the TV again to be sure that this is not the problem or will this cause other problems?
Thank you in advance!

from piccap.

Hi
Is there any other solution to this issue? Because the app doesn't start for me either. It only works if you send the TV to the reboot from the app itself.

Welcome. This looks like exactly what I need. but lack of knowledge to setup ssh connection(

from piccap.

Autostart is already fixed in newer development versions. If you aren't able to connect to your TV using SSH, just wait a bit more until release.

@TBSniller :

1. how to we start & stop the service.
2. As the autorun does not work, therefore I need to STOP and START manually, sometimes it happens that the service does not start anymore, then I need to reboot completely, any chance via SSH? What the exact command to start / stop the service
3. Are there any precompiled more recent development versions avaiable? I dont have any enviroment setup yet, therefore I am asking. When is the new release planned approx?

from piccap.

2. sometimes it happens that the service does not start anymore, then I need to reboot completely

try killall -9 hyperion-webos via ssh and start should work

thank you, and restarting (starting) ? hyperion-webos & ?

from piccap.

luna-send -n 1 'luna://org.webosbrew.piccap.service/start' '{}'

from piccap.

in my case, I created a script on the TV, and call it via SSH twice if the autostart does not work

#!/usr/bin/sh
pc_status=`luna-send -n 1 'luna://org.webosbrew.piccap.service/start' '{}'`
if echo $pc_status | grep -q '{"returnValue":false}'; then
	killall -9 hyperion-webos
	luna-send -n 1 'luna://org.webosbrew.piccap.service/stop' '{}'
fi

thanks @mksy, I will give it a try. Looks good.

from piccap.

With latest release we reworked almost anything. Please check it out, it should work now for webOS 3.4 and above.

from piccap.

Thanks for the new version. But its now even worse. Need to reboot to get it working. Before manul restarting worked at least with 0.23

from piccap.

@denimjeans Can you please create an issue here https://github.com/webosbrew/hyperion-webos/issues ?
We would also need some logs. You can get them in Log Tab in PicCap -> First set it up using buttons in log tab -> Then produce your problem -> then get last log -> Put the picture in your issue.

You can also get logs directly from CLI by manually running it: https://github.com/webosbrew/hyperion-webos#running
Make sure to kill proccess kill -9 $(pidof hyperion-webos) and PicCap before

@TBSniller one thing more: could you please let me know on how to downgrade from 0.41 to 0.23. I have managed to copy the 0.23 ipk file to /tmp. But not sure on how to install now? ipkg and opkg not working here. thanks

@denimjeans sure, you can use Install command mentioned here: https://github.com/TBSniller/piccap#manual-way
Just replace it with your filename. When its finished you can exit it with CTRL+C

Btw Just make sure to uninstall latest version before installing the old one
