Script to get PID list for the selected channel

sentaro · Nov 21st 2024

Hi,

I would need to find a way to get namespace and PID list for the currently tuned channel, in order to pass TID, NID, SID and hopefully the namespace to another script for further eleborations.

Such values are available on the Info screen on the receiver itself and can be read by dreambox of course, but I need a way to get them programmatically by a bash script (so to pass the values to another python script).

Are you aware of any easy way to get those data from the shell?

Thank you!

After looking around, I will take advantage of the API from the REST API of OpenATV web interface, then I will parse the returned json that includes the service reference for the current station.

in PLi there is a console output for Menu -> Information -> Service, not just on screen

Using chatgpt - maybe something like this. Not checked it though. XML version

And don't forget to convert any .sh files to unix ending.

Bash

#!/bin/bash

# Fetch the XML data (replace with your Enigma2 box details)
DEVICE_IP="192.168.1.100"
PORT="80"
XML_DATA=$(curl -s "http://$DEVICE_IP:$PORT/web/getcurrent")

# Check if XML data was retrieved
if [[ -z "$XML_DATA" ]]; then
  echo "Error: Unable to retrieve XML data."
  exit 1
fi

# Function to extract XML values using xmlstarlet
extract_value() {
  echo "$XML_DATA" | xmlstarlet sel -t -v "$1"
}

# Extract Service Information
SERVICE_REFERENCE=$(extract_value "//e2servicereference")

# Extract Current Event Information
CURRENT_EVENT_NAME=$(extract_value "//e2event[1]/e2eventname")
CURRENT_EVENT_DESCRIPTION=$(extract_value "//e2event[1]/e2eventdescription")

CURRENT_EVENT_REMAINING=$(extract_value "//e2event[1]/e2eventremaining")
CURRENT_EVENT_CURRENT_TIME=$(extract_value "//e2event[1]/e2eventcurrenttime")

# Extract Next Event Information
NEXT_EVENT_NAME=$(extract_value "//e2event[2]/e2eventname")
NEXT_EVENT_DESCRIPTION=$(extract_value "//e2event[2]/e2eventdescription")
NEXT_EVENT_START=$(extract_value "//e2event[2]/e2eventstart")
NEXT_EVENT_DURATION=$(extract_value "//e2event[2]/e2eventduration")

# Convert UNIX timestamps to human-readable format (if `date` command is supported)
if command -v date &>/dev/null; then

yeah, thank you.

I'm done. at the end I made the rest request into a python script rather than in the bash script.

This because I need to make calculations on the PIDs and namespace in order to compute the softcam hash of the tuned channel, you know...

It's working now, basically this is what it does (not that elegant I know...):

1) a bash script passes a "value" ( ) as a parameter to a python script

2) the python script gets the servicereference by the rest API, then PID parsification occurs, getting SID, TID, oNID, E2 namespace; then after elaboration the softcam hash is produced and softcam k*y file is updated with a new entry.

3) the bash script forces a softcam restart in order to read the just updated k*y file

btw, are you aware of any API reporting the color sampling format, basically the "4:2:2" or "4:2:0" information?
