autostart tv

gbi · December 22, 2017 at 7:51 AM

Hi folks,

I'd like to autostart a specific tv program automatically when libreelec starts. By chance I stumbled over the autoexec.py scripting facility, which seems to be well suited for doing this.

But as I'm not a real programmer I'm not able to write such a script. Maybe one of you folks already has such a script or can help me to write it ?

Or is there another way to autostart a specific tv program ?

Thanks in advance

You can retrieve the channel list with command

Code

curl -H 'Content-Type: application/json' -d '{"jsonrpc": "2.0", "method": "PVR.GetChannels", "params": {"channelgroupid": "alltv", "properties" :["uniqueid"]},"id": 1}' http://127.0.0.1:8080/jsonrpc

look for channel id and then use autoexec.py something like

Code

import xbmc
import xbmcgui
import xbmcaddon
import json
import time
# sleep few seconds
time.sleep(5)
# play a channel 149
jsonCmd = '{"jsonrpc":"2.0","id":1,"method":"Player.Open","params":{"item":{"channelid":149}}}'
jsonRv = xbmc.executeJSONRPC(jsonCmd)

I think last channel can be played automatically (set somewhere in pvr settings).

thanks a lot

The first one works when I change the port to 80, there is nothing listening on port 8080:

Code

I have seen that the channelid I want to use is 1088.

The python script throws an error:

Code

11:31:58.090 T:1612706720   ERROR: EXCEPTION Thrown (PythonToCppException) : -->

-->End of Python script error report<--

I see that it is a syntax error, but I can't identify it

Or can it be caused that tvheadend is not running at the time the autoexec.py is executed ?

Code

**vpeter** · December 22, 2017 at 11:55 AM

I made mistake on line 6 with jsonCmd. Now it is ok.

gbi · December 22, 2017 at 12:27 PM

can you tell me the correct syntax, please

**vpeter** · December 22, 2017 at 12:49 PM

Quote from gbi

can you tell me the correct syntax

I fixed my code above.

But first you need to get channel list to get correct id of a program.

gbi · December 22, 2017 at 2:54 PM

ok, understand regarding the fixed code. My bad.

Now nothing at all happens. It does not switch to the channel I like it to switch, and there are no messages in the kodi.log, at least no messages that seem to be related to the autoexec.py.

How can I make a debug NOTICE in the autoexec.py ? Can this be done with printf ?

**vpeter** · December 22, 2017 at 5:44 PM

Did you even get channel id with curl? If not autoexec will not help you.

Enable kodi debug log and you will see what is happening with autoexec.

gbi · December 22, 2017 at 6:46 PM

yeah, I've got the channelid, it was the first step I did.

Code

40818},{"channelid":1265,"label":"arte HD","uniqueid":1963091052},{"channelid":1088,"label":"3sat HD","uniqueid":1026189214},{"channelid":1004,"label":"tagesschau24 HD","uniqueid":640869133},{"channelid":1141,"label":"ZDFinfo HD","uniqueid"

It is the {"channelid":1088,"label":"3sat HD","uniqueid":1026189214}, so channelid -> 1088

Have activated the kodi debug log, a lot of info is generated. The last occurence of 'autoexec' in the log is as follows:

Code

19:24:36.149 T:139715384309504    INFO: CPythonInvoker(3, /home/gb/.kodi/userdata/autoexec.py): script successfully run
19:24:36.149 T:139715384309504    INFO: Python script stopped
19:24:36.149 T:139715384309504   DEBUG: Thread LanguageInvoker 139715384309504 terminating

The other occurences of 'autoexec' also do not indicate errors, but it does not work.

**vpeter** · December 22, 2017 at 6:55 PM

The problem is that script is executed BEFORE pvr client is even active. I changed my script above and add short delay with sleep. Try it - it works here.

gbi · December 22, 2017 at 7:34 PM

well, I also have noticed/suspected this, that tvheadend starts later than autoexec.py is exec'd. I have even increased the time.sleep() to 30 or even 90 seconds, but no success, nothing happens

gbi · December 22, 2017 at 8:10 PM

ok, I have injected an error at the end of the autoexec.py script, with a time.sleep(xx). Simply to get an error popup onscreen when the error occurs. Guess what, this popup comes immidiately, before the startup of tvheadend has happend, it does not matter if the time.sleep is 30 or 90 or whatsoever.

Sigh

gbi · December 25, 2017 at 5:36 PM

Hi all,

just for the records: this solution does not work ! I'm sorry.

The time.sleep() at line 7 has no effect, it does not delay further execution of autoexec.py.

I'm too less a python specialist to track down why it does not work.

Suggestions for doing an 'autostart tv' or to get the above script to work are welcome

Thanks in advance.

**vpeter** · December 25, 2017 at 5:59 PM

Well, I'm not sure what you are doing but works perfectly fine for me. It is probably wrong approach but it works. Also sleep works as you can see:

Hi,

now it works.

I had 2 problems:

1. the sleep time had to be at least around 30 seconds. Libreelec and tvheadend are running on a raspiv2

2. strange enough it does not work with channelid 1088 (I have rechecked the output of curl, 1088 is listed), but it does work with another channelid I found in the list :

Code

{"channelid":1265,"label":"arte HD","uniqueid":1963091052}

It also does not work when I run tvheadend on the raspi and stream it's output to my PC which also runs kodi.

So this solution is may be the wrong approch (as you said) but at least it works

Thanks a lot for your kind support

**vpeter** · December 26, 2017 at 10:58 AM

Script could be smarter to check if pvr is ready and nit hardcoded time.

Maybe it is something wrong with required channel id? Does it switch to it with curl command?

gbi · December 26, 2017 at 12:11 PM

the hardcoded time doesn't matter in my case. To check if pvr is ready would be smarter, agree.

what is the curl cmd to do a channelswitch ?
