Continuous zapping through channels

Re: Continuous zapping through channels

I understand but for some sats it's not available. Even many channels don't have websites.

I want this for FTA channels which don't have EPG. Most encrypted ones have EPG. So the ecm delay isn't an issue.

Even for encrypted ones, it won't be a very bad idea to take a look at each channel, giving allowance for a larger ecm delay.

Re: Continuous zapping through channels

Hi
Is there a way to make dreambox zap through channels automatically. So it zaps to a new channel every 5 sec for example.

It's not that hard to do that: just write a loop script where, inside the loop, you put commands to zap the channel list.

Example for enigma1:

#!/bin/sh

while [ 1 ]
do
  wget -q -O dev/null http://root:PWD@ IP_DREAMBOX /cgi-bin/zapTo?path=1:0:1:2144:3070:13e:820000:0:0:0:
  sleep 5
  wget -q -O dev/null http://root:PWD@ IP_DREAMBOX /cgi-bin/zapTo?path=1:0:1:213f:3070:13e:820000:0:0:0:
  sleep 5
  wget -q -O dev/null http://root:PWD@ IP_DREAMBOX /cgi-bin/zapTo?path=1:0:1:2140:3070:13e:820000:0:0:0:
  sleep 5
  wget -q -O dev/null http://root:PWD@ IP_DREAMBOX /cgi-bin/zapTo?path=1:0:1:2141:3070:13e:820000:0:0:0:
done

exit 0

This code loops through 4 channels but you can add all channels you want.
Remember this is an infinite loop, so you need another script to kill it when you have done.

@gianni253

nice,

the next step: how to start this script with the dm500 addon menu

otherwise, i can only start it by mean of a telnet session ...

i prefer from the remote control

For enigma2 I put all my scripts in a given directory (example /usr/scripts) and then use a plugin (Script Executer) to launch them with remote control.

For Enigma1 it's even simpler ... put all scripts in /var/tuxbox/plugins, create corresponding .cgf, and launch them with yellow button.

Re: Continuous zapping through channels

For Enigma1 it's even simpler ...

1.- put all scripts in /var/tuxbox/plugins,
ok

2.- create corresponding .cgf,
i did
cp CCcaminfo.cfg mycmd.cfg
vi mycmd.cfg
cat mycmd.cfg

name=mycmd
depend=
type=2
needfb=0
needrc=0
needlcd=0
needenigma=0

( ... ? what's that params ? ... )

3.- and launch them with yellow button
ok

answer:
/var/tuxbox/plugins/mycmd.so no such file

-> how to create this mycmd.so file

ps: mycmd is a bash script

[gianni253]

Re: Continuous zapping through channels

name=mycmd
depend=
type=2
needfb=0
needrc=0
needlcd=0
needenigma=0[/FONT]

Put type=3

Re: Continuous zapping through channels

Thanks Gianni. This looks great.

-Is it possible to simulate a key press (eg. channel+ or channel -) in a script?

-Will the same script work for enigma2? Do I have to replace ip ...?

-How to stop the script?

Thank you very much for your help

the interaction from the remote control to the system goes via the interface and enigma 1/2

so the question is how the remote control interact with enigma,
and how enigma interacts with the bash script

When I had enigma1 I could send the remote control commands through a c# app:
WebBrowser.Navigate(@"http://<Box IP>/cgi-bin/rc?106");
where 106 is the key code.

I didn't have much time to test this on enigma2, but it's obviously different.
I don't know if this will help here.

In E2 it's fundamentally the same .. only commands are a little bit different.
To zap to a given channel:

wget -q -O - http://root: PWD @ IP_DREAMBOX /web/zap?sRef=1:0:1:213F:3070:13E:820000:0:0:0:

Coming to remote control, here's the command syntax:

http://dreambox/web/remotecontrol?command={command}

and control codes ...

116 Key "Power"
2 Key "1"
3 Key "2"
4 Key "3"
5 Key "4"
6 Key "5"
7 Key "6"
8 Key "7"
9 Key "8"
10 Key "1"
11 Key "0"
412 Key "previous"
407 Key "next
115 Key "volume up"
113 Key "mute"
402 Key "bouquet up"
114 Key "volume down"
174 Key "lame"
403 Key "bouquet down"
358 Key "info"
103 Key "up"
139 Key "menu"
105 Key "left"
352 Key "OK"
106 Key "right"
392 Key "audio"
108 Key "down"
393 Key "video"
398 Key "red"
399 Key "green"
400 Key "yellow"
401 Key "blue"
377 Key "tv"
385 Key "radio"
388 Key "text"
138 Key "help"

Re: Continuous zapping through channels

so, the remote control send a msg to enigma when hitting a key, as

(e1): --http://ip/cgi-bin/rc?_code_
(e2): --http://dreambox/web/remotecontrol?command=_code_

where _code_ is a key code, like 407 as an example

this _code_ is switched by enigma to the adhoc subprocess (like next channel of the list, as an example)

all this show us how the script gains access to the tuner ressources (as next channel subprocess) via e1/2:
curl --http://127.0.0.1/web/remotecontrol?command=407 >/dev/null
curl --http://ip/cgi-bin/rc?_code >/dev/null

and make our friend sjamesamuel happy , to zap along a bouquet:

WebBrowser.Navigate(@"http://dreambox/web/remotecontrol?command=407"); # next


also, and further more,
how enigma1/2 can send this related message _code_ to the bash script ?

[gianni253]

Re: Continuous zapping through channels

how enigma1/2 can send this related message _code_ to the bash script ?

It's only a one-way communication: bash script sends command to enigma1/2 but there's no return code.
And if you want to know what's the channel you are currently tuned in, there's another command ...

[aplok]

Re: Continuous zapping through channels

... just an idea

if enigma1/2 traces the entries (from remote control) into a file,
like such an history,

if this enigma1/2 cmd-history-like file is readable and intelligible,

we can then imagine a deamonized bash script reading it,
to trap the some private key.combination
to trig process

Re: Continuous zapping through channels

Thank you very much Gianni.
You're always so helpful.

I used this for channel up:
wget -q -O dev/null http:// ip here /web/remotecontrol?comman
d=106 for channel up (right key) as command and it worked!

Channel down is 105.


-Would you please tell me how to make a script to stop the running one?

-Are there any documentations for this matter?

Thanks

i suggest this:
kill -9 $( ps |grep myscript |grep -v grep |awk '{print $1}' )
