[Partly Solved] Oscam SAT-IP Descrambling only works if start the channel via VLC first

g gebruikerh · 2019-06-13T20:17:41+00:00

Hi All, After a few day testing trying etc, I got the SAT-IP connection to my Panasonic client working:). But now I have an issue with my descrambling. I h...

g gebruikerh

Ok, I installed minisatip and let it connect via a DVBapi client and the descrambling works... But I only could get it working with the internal tuner of the wetek play. And the HD channels use a load of the processors so it's not the solution and I would like to get it working with TvH.

I thing I think that I know it for sure. There is something missing in my TvH config als all the parts seems to work.

Strange that it HD channels overload CPU
start minisatip with


minisatip -E

Map it in TVH and restream with TVH SAT>IP server
In this case TVH will descramble

There are some know issue's about it.

About minisatip -E, if we use TvH SAT>IP will not descramble because that my whole problem if use TvH it won't decramble. Or I'm in correct here?
I will see if I can get an stream for minisatip with RTSP so we can do some testing in TvH

Let's make experiment.

Play with TV some channel with TV cannot.
Post Frequency QAM and SR of mux,

from status or from service information pids of this service.

From upper info will make rtsp link to test with.

Simbol rate?

Symbol rate? sorry ofcourse you need that one. 6900000 Sym/s (6900 Khz/s if I'm correct).

This one placed in oscam as I would like to check Tvh first only put listen_port 9001.

Try both in VLC

g gebruikerh

got an error on both. But are we not missing some pids? 5001,*18*,5012,5011,*17,16,*5101,*0,*5000,*1*,5102,5103,8187.

The other problem is that the internal Wetek player tuner is not stable on minisatip... sometimes it works it tunes, sometimes it don't tunes...So it not the correct testing i think... I will try to google to find out to connect my homerun tuner as that one is more stable.

Saen Acro

This are for service use, but add them in tvh you can see used pids audio/video/subtitles
on frequency by mistake I add one more zero

Next is debugging deep in url sniffing ;)

Hi,

See config attached. Should be correct. But all the same error message.

For the debugging Wireshark?

Try with TV requests, they are important.
