I was reading this thread: https://forums.openp...ecm-by-default/

and I noticed:

 

"On my ET9200 with Openpli 4.0,  when I start a recording with the option: "scrambled, record ecm" in Type of recording:

 - If during the recording I watch the recorded channel, the recording is descrambled which is not the expected result"

 

The answer:"Yes this is normal behaviour. The descrambling registers are loaded by the softcam for the pids you're watching, which makes them being descrambled for the recording as well. The recording is just a tee of the stream you're watching in this case."

 

My question is - when I record scambled with ECM and switch to the recorded channel during recording, it get descrambled and I get a partially descrambled recording?

If so, how can I fix (descramble the scrambled part) such a recording?

 

Can I offline decode the scrambled part?

Does it recognize which part of the recording is scrambled and which already descrambled?

When you watch the channel or also parts of the recording it will be decoded... As far I know nobody will notice.

 

Can I offline decode the scrambled part? -> See menu option in MoviePlayer... It is now on the 2do list to do this when the box is in standby.

Does it recognize which part of the recording is scrambled and which already descrambled? -> You need to decode the complete file to a .decoded file.... after this you can yourself delete the (partly) encrypted one...

I hope that offline decoding in 4/8 times real speed is also on that list?

Thank you.

So if I'm getting it right, when I have a partially descrambled recording and I let it offline decode, I get a fully descrambled recording?

And the same happens if I simply watch the (whole) recording?

Afaik it also depends on the hardware. Some boxes cannot do offline descrambling.

Using CI module or softcam? There is quite a difference there.

 

Basically partially descrambled recordings can be descrambled again and then only the still scrambled packets will be descrambled.

That's already possible, tweak the "offline decoding delay" parameter and be prepared to see black smoke out of your subscriber card :)

At this moment I’m experimenting with doing the descamble as soon the box is in standby... But there are some issue’s and stuff that still needs to be designed for the ui... I’m still at a phase where I try to collect all the cullpits...

Before trying that I would like to know what thw parameter "offline decoding delay" actually does and if the 'black smoke' would harm my CDS-card.

It does one ECM per time period you configure... e.g. m7 has per 10 sec an ECM.... when you set it on e.g. 5 sec the decoding speed is 2 times but the card Will be loaded as seeing two channels at once.when you put it on 1 sec the speed is 10 times, but you card will go in punishment mode guaranteed... please also note when you are also watching with the card at the same time the SID filters can not block the extra ECM’s.... so you can get multiple ECM (decoding recording + live) that could also put a card in punishment mode... then also think about fallback tuner server and the chaos is on!
In general this it sounds easy, but it isn’t... and mayby that is why it isn’t implemented yet... (and maybe I should firstly limit the scope of auto offline decoding of a recording)

Your subscriber card works on black smoke. If the smoke is out, it can't work anymore :)
