Hi @Adam792

Can you check if my abertis.py is correct?

import sys

pid = int(sys.argv[1])

packet = sys.stdin.buffer.read(188)

while packet !="":
tspid = ((packet[1] & 0x1f) << 8) | packet[2]
if tspid == pid :
afc = packet[3] & 0x30

if afc == 0x10 :
sys.stdout.flush()
sys.stdout.buffer.write(packet[4:])
elif afc == 0x30 :
sys.stdout.flush()
sys.stdout.buffer.write(packet[packet[4]+5:])

packet = sys.stdin.buffer.read(188)

i get this error

Looks correct, I guess the paste of the code here has just removed the indenting/tabs? (they are important!)

The 12548V mux looks correct too, is the URL for your "Abertis PID 702" IPTV mux set to :

Code: 
pipe:///home/hts/Abertis/tdt.sh 1a07a33b4b16c59ad969dfe24a463fcf 702

?

It looks like the Python script is failing because it's getting no data coming into it. You may have to install curl if it isn't already -

Code: 
sudo apt install curl

This is great! Thank you :)

I'm using a C version myself, but just that I made quickly from code used in another tool (the sat DAB ETI-tools). This here looks much nicer, dedicated for the purpose!

Edit: Replaced mine with yours from here, working perfectly. Thanks again

try this
1. in Menu - Setup Network WebInterface
"disable anti-hijacking and token-based security in web interface settings" (big thank you again @matt33 and @Rickk)
2. (all files with permission 755) create the abertis.service file in /etc/systemd/system and insert that
Code: 
[Unit]
Description = ABERTIS service

[Service]
ExecStart = /ect/init.d/astra-sm &

[Install]
WantedBy = multi-user.target
3. install astra-sm and libaio from ipk
4. with command activate service with:
Code: 
systemctl enable abertis.service
5. with command init 4 stop Enigma, replace with lamedb, init 3 and reboot

I guess that libriaries are already there !

root@dm920:/tmp$ ./astra -v
Astra SM 0.2
root@dm920:/tmp$ ./t2mi_decap -v
./t2mi_decap: invalid option -- 'v'
error: usage: ./t2mi_decap OPTIONS -i <infile> -o <outfile>

All bin are working with me but when I put a channel I don’t have anything in astra log.
As if it is not processed !

Done. Can use ciefp setting for lamedb ?

Within Ciefp setting I see the relevant keys in oscam logs !
So the http stream call the relevant abertis pid, but no picture !
any command to see astra log in syslog ?
