Using the "fe" query attribute does not follow the frontend numbering in WebIF, for using frontends connected to different LNBs

[patacalas]

Hi again. I can't find the way to configure my Sat>IP server on a Gigablue UHD Quad receiver with an extra PnP tuner. FBC tuners (frontends 0-7) are using Unicable LNBs: Astra - Position A Hotbird - Position B Hispasat - Position C

I've just added an extra twin tuner (frontends 8-9), using a twin legacy LNB for Eutelsat 7B/C, and getting signal from that satellite via Sat>IP is impossible for me.

Frontends 8 and 9 are set as LNB (no diseqc), but when I try to get an Eutelsat 7B/C channel Sat>IP serves the first frontend available and not the correct one, even using the "fe" query attribute. The only way I can get Eutelsat 7B/C is disabling frontends 0 to 7.

How can I get it working?

Thanks in advance for your response.

Hi @patacalas

So fe=8 does not select frontend 8? Could you make an example request with VLC (with fe=8)and give the log of SatPI?

Thanks for testing.

Hi @Barracuda09 I think that I've found the solution. The issue is about the frontend numbering. If I request fe=8 SatPI serves frontend 7. I just thought that I should use the same frontend numbering showed in SatPI web interface.

For example: TRT WORLD (Eutelsat 7B/C) http://192.168.194.39:8875/?freq=10886&sr=30000&msys=dvbs2&mtype=qpsk&fec=56&pol=v&src=1&fe=8&pids=0,1,16,17,18,37,2337,3335

Tue May 10 15:08:46.3182 2022  6  Frontend: 3, New session but this stream is not enabled, skipping...

If I request fe=10 SatPI serves frontend 9 and everything works fine.

Thanks for helping.

Hi @patacalas

Yes you are correct, this is not intuitive. I have to maybe number the Frontends in the WebIF accordingly. (I always keep confusing this as well) according to the specs fe=x should be between 1 and 255

Thanks for testing
