Multistream support

[perexg]

Appearently STV0900 demodulators with chip id 0x30+ supports multistream.

The axe hardware has chip id 0x30:

~ # axehelper i2c_reg_read 0xd0 0xf100
0x30

Linux kernel code:

https://github.com/torvalds/linux/blob/64c5e530ac2cab7e710c3bd08ef8594a016e4f9a/drivers/media/dvb-frontends/stv090x.c#L3433-L3474

https://linux-media.vger.kernel.narkive.com/RyQdvAhf/patch-stv0900-multistream-support

Goals:

• inject the current closed source DVBAPI driver from Inverto to support it
  • old DVBAPI (use another way to control PLS/MIS filter - sysfs or proc)
• extend minisatip to support PLS/MIS settings

It's really working! Tested on 5.0W transponder 12648V. The kernel hack is done - a0060a0. It seems that hardware is capable to decode only GOLD PLS scheme.

Ok, build 15-rc5 is out with the multistream support, tvh supports the newly added SAT>IP extension, too.

[perexg]

Build 15-rc6 supports both GOLD and ROOT PLS schemes (with latest tvh).

[perexg]

It seems that there's just one PLS scrambling algorithm and ROOT/GOLD just specifies a different way to get the starting value for the descrambler:

The COMBO seems like a bug..

BTW: oe-alliance/satip-client#10 , even enigma2 on my openpli/vuplus2 can do multistream through SAT>IP protocol now !!!!

Is it possible, that you provide a satipclient package for the vu solo 2?

Note that if you like to activate the TCP data transport add tcpdata=1 option like:

0=desc:minisatip,ipaddr:192.168.100.237,tuner_type:DVB-S,uuid:11223344-9999-0000-b7ae-0022b7f0056e,vtuner_type:satip_client,tcpdata:1

Thanks, I will test it tonight

Build15 final is out with the multistream support.
