Hi guys,

 

May be you noticed, new and blazing fast Vu+ Solo2 devices suffer a bug that causes CI modules cannot initiate high bitrate support properly after boot, reboot or GUI (Enigma) restart.

 

I wrote "VU+ Solo2 CI High Bitrate Fix" plugin to fix this problem. This plugin supports both OE 1.6 and OE 2.0 and hopefully covers all CI modules. As always, I wrote and test the plugin on the latest PLi image!

 

You can always visit my blog for the original download link, future updates and my other E2 plugins:
http://buyukbang.blogspot.com

I also attached current version of the plugin to this post.

 

Wish you enjoy it !

@Mods, could you please put this file to PLi Solo2 feeds? Thanks !!!

Just install the file and restart Enigma2. There is no GUI for this plugin, so don't try hard to find an entry on the Plugins menu. This plugin does its job on the background silently while Enigma2 is starting. After CI initiates properly, the plugin terminates to free system resources it uses.

Instead of putting weird postinst scripts in order to have python 2.6 and 2.7 binaries inside your ipk, just put the source .py file in it. I guess the 2K python file doesn't have some intellectual property that deserves to stay binary only.

do we need just

import enigma
from enigma import eTimer, eDVBCI_UI, eDVBCIInterfaces, iServiceInformation
from Plugins.Plugin import PluginDescriptor
autoStartTimer = None

def Plugins(**kwargs):
    return [
        PluginDescriptor(name = 'VUSolo2CIHighBitrateFix', description = 'VUSolo2CIHighBitrateFix', where = PluginDescriptor.WHERE_SESSIONSTART, fnc = autostart)]


def autostart(reason, session = None):
    global autoStartTimer
    print '[VUSolo2CIHighBitrateFix] autostart'
    if reason == 0:
        if autoStartTimer is None:
            autoStartTimer = AutoStartTimer(session)
        
    


class AutoStartTimer:
    ciCaids = []
    
    def __init__(self, session):
        self.session = session
        self.timer = enigma.eTimer()
        self.timer.callback.append(self.onTimer)
        self.timer.startLongTimer(2)

    
    def onTimer(self):
        
        try:
            state = eDVBCI_UI.getInstance().getState(0)
            if state == 0:
                self.timer.stop()
            elif state == 1:
                self.timer.startLongTimer(2)
            elif state == 2:
                self.ciCaids = eDVBCIInterfaces.getInstance().readCICaIds(0)
                if not self.ciCaids:
                    self.timer.startLongTimer(2)
                    return None
                service = self.session.nav.getCurrentService()
                if service:
                    pass
                info = service.info()
                if service is None:
                    self.timer.startLongTimer(2)
                    return None
                if service:
                    pass
                info = service.info()
                if not info:
                    self.timer.startLongTimer(2)
                    return None
                serviceCaids = info.getInfoObject(iServiceInformation.sCAIDs)
                for serviceCaid in serviceCaids:
                    for ciCaid in self.ciCaids:
                        if ciCaid == serviceCaid:
                            eDVBCI_UI.getInstance().setClockRate(0, eDVBCI_UI.rateHigh)
                            self.timer.stop()
                            return None
                self.timer.startLongTimer(2)
            else:
                self.timer.startLongTimer(2)
        except:
            self.timer.startLongTimer(2)


    
    def debugLog(self, log):
        
        try:
            f = open('/tmp/VUSolo2CIHighBitrateFix.log', 'a')
            f.write(log + '\n')
            f.close()
        except:
            pass

 

or something more ?

[malakudi]

uncompyle2 ?

[buyukbang]

Nice findings. I wasn't aware of uncompyle2 and it really opens all pyo files I tried. This leads lots of new code to play with.

It is not difficult to make python code it fails to decompile :-)

[Persian Prince]

i'm working on a feature for our enigma2 image (Persian Empire) and our andorid 4 app (Persian Grandeur) so you can easily decomile any pyc/pyo file

 

specially when you can do it with touch on your phone/tablet

 

[Lost in Space]

Wow, I'm really scared now

[buyukbang]

So,how ? I couldn't find an example that cannot be decrypted?

[Lost in Space]

Why should I tell you ?

 

And the trick is easy if you look at the right places ... and understand how python compiler works

[Persian Prince]

Wow, I'm really scared now

 

you should not as all your python files are open source

 

but it would be nice if you share C codes too

[Lost in Space]

Why should I, as there are plenty of disassemblers available

[Persian Prince]

any good example that can do it easily ?

[buyukbang]

Well, after all I read about the decompilers, I believe no trick will be safe for python. Using C (may be partly) seems as the best solution.

[Lost in Space]

Why should I tell you where the key of my house is ?

 

And you could steal the code but not the understanding ...

[hemertje]

enough now with the personal fist fights

 

back on topic!

[Persian Prince]

btw i tried REC , boomerang and some other things i think

the point is you can't decompile an one-way code

[Lost in Space]

We are not fighting as my fists are on the keyboard :-)

 

And yes, using code that runs only once is one of the possible solutions that are commercially available like one time encryption keys.

 

Back to topic - Just delaying detection to give more time is not an elegant but working solution

[Persian Prince]

i think it's what Gemini do , spliting python codes to binary files with TPM check

 

but which one is faster ? python compiled or binary files ?
