I am runnning the latest openPLI on a VU+ Duo2 and want to stream an encrypted channel.

The problem is, the stream I get has the "even"/"odd"  key TS stream bits already removed, like it is already decrypted. But this is not the case, the STB cannot decrypt this channel.

I already disabled/enabled the "Descramble http streams" setting and restarted the whole system, but no change, the stream never has the "even"/"odd" bits set.

 

Is this a known limitaiton of the Duo2, or am I doing something wrong?

Are you running an actual or up to date image?
This problem should be solved in the latest drivers.

I am using

OpenPLi-4.0-beta-vuduo2-20150703_usb.zip ( 2015 / 07 / 03 ).

I did some more testing on a channel that can be decrypted by the duo2:

 

"Descramble http streams" on: stream gets decrypted OK.

"Descramble http streams" off: odd/even key bits are missing, but the stream is not decrypted correctly.

 

So the setting works, but the tuner always seems to decrypt even when it should not.

I have found some drivers which could maybe solve this problem:

 

update proxy drivers
20150623
- Fix tuning problem(AVL6211, duo2, solose)
- Improve vtuner(satip support)
- Fix scrambling bit in recording
- Improve transcoding

vuplus-dvb-modules-vuduo2-3.13.5-20150623.tar.gz (http://archive.vuplu...20150623.tar.gz)

 

the drivers which are used by openPLI at the moment

But the question is: Will openPLI work with these drivers?

[ClipMaster]

I did a binary compare of the files, and noticed that only dvb-bcm7424.ko is different than the current drivers the latest openPLI is using.

After replacing it, everything works now!

 

So this driver should be updated in the openPLI image I think.

 

Thanks for your help

As I recall right this driver has been implemented with the last update of the BSP layer, or at least should have been.

[Rob van der Does]

The last driver date is 23/6 and this has not yet been implemented in PLi (and neither has the new HbbTV version if I'm not mistaken).

[Erik Slagter]

Watch the date...

[ClipMaster]

So why the "OpenPLi-4.0-beta-vuduo2-20150703_usb.zip" does not include this driver?

Fixed.
