hi,

i need your help to solve this problem 

i am writing  an oscam emu reader that needs  service freq and sat position for discrambling, 

i want to get this information directly from oscam c++ code.

 

[littlesat]

Why?

[steavebba]

the oscam code is writen in pure C and any moudule shoud be writen on c/c++.

[Erik Slagter]

I suggest streamboard, where the Oscam developers are?

[steavebba]

I dont think thy had the right answer,

in the oscam code thy use files to get information about the sevice

for exmple, thy use oscam.servi to feed the chanal name to  thier web interface

and oscam.twin to get sat an freq from caid and provider id in some serial protocoles. so i want to get this information directly from enigma insted of files.

this is an enigma level problem not related directly to oscam.

i am wondering why enigma designers have decided to force developers to use python to write plug-ins .?

Linux is all about c/c++  and providing a c/c++  api to the enigma layer is can be helpful also.

 

the problem  can  be solved by using python helper plug-in that will feed information to  the c++ code via Linux sockets. But this have no sense for me to write plug-in with socket and thread logic ....etc. to just get the freq and the sat position of the current channel

[Erik Slagter]

Yeah beats me too... Probably because more people (think that they) can program in Python.

[littlesat]

E.g. the hotplug stuff in OpenPLi uses sockets via python.... maybe an example,,,,?

Nobody was ever forced, E2 supports Python and also C(++) code for plugins.

i was not able to find any code in c++ that can use the E2 layer stuff like screens (UI) service information ..etc.  

[littlesat]

Again.... why do you need this..... ? And probably as oscam is dowing cw it might already be in....

Exactly. It's impossible to create a plugin in C++.

[littlesat]

You have to create a plugin in python.... this will not 'say' the plugin might include a binary (blob) compiled from C or C++ or something in between C and C++... e.g. Bitrate viewer is an example of such plugin with python hookup user interface part and added C code.

Did you see the the interface between Python and C++? Ugly at best...

[steavebba]

Again.... why do you need this..... ? And probably as oscam is dowing cw it might already be in....

 this information it is nedded by some sharing protocoles that i need to implement in oscam.

oscam is dowing cw by its dvb api interacting with the /dev/dvb/adapter0/ dvmux...directly it so low level... and the information that i need is in the enigma level, i cant figure out how to get it.

[littlesat]

Yep... The interface between python and c++ is grrrrmlllrrkd^]^{^^}}*

And still no idea what you exactly want to do....

in this scenario the python code will be a warper of the c code there is no problem i can make code in c/c++ and use SWIG to generate python interface and use it to write the final plugin that wil be used by enigma. the python is a top layer of the c++ code

 

but what to do if the c++ code needs stuff from the enigma layer that is available via python, for example the oscam is running as a linux process not as an enigma plugin, what to do in this scenario ? we have no choice ! use a python helper plugin or the web interface api !

@littlesat,

 

Some people sold closed source boxes with integrated CS, and to retrieve the DCW they use the service freq and sat position for the sharing.

So steavebba simply tries to hijack this system and make it compatible with OScam which doesn't have this kind of information by default for the descrambling.

 

Pr2

[steavebba]

@littlesat to be honest with you that is exactly what i am doing (a hard work of reverse engineering of  closed box).

 

 

 

By the way, i used unix domain sockets to pass information from enigma layer to oscam emu, and it works but from a developer point of view it is not the proper way to solve this problem.

 

Thank you all.

@steavebba If I correctly understand what you want, you can use the Python API in C or C++.

Examples can be seen for example in my plugin blurayplayer: https://github.com/T...er/tree/openpli
