Raspberry Pi as minisatip server

Post by zorrua »

Hello,

I am new in this forum, I want to try minisatip to share my satellite channels to my LAN. I have a dish pointing to Astra19.2E and I have a OSCam server in the LAN.

I have a Raspberry Pi Model B (Rev 2.0, 512Mb) with one USB DVB-S2 device. I installed "2016-09-23-raspbian-jessie-lite.img" on it and install minisatip this way:

Code: Select all

apt-get update
apt-get upgrade
reboot
apt-get install git libdvbcsa-dev libssl-dev
git clone git://github.com/catalinii/minisatip.git
cd minisatip/
./configure -> https://paste.debian.net/896749/
make -> https://paste.debian.net/896750/
Then execute it this way:

Code: Select all

# ./minisatip -f
[19/11 13:35:37.741 main]: minisatip version 0.5.67, compiled with s2api version: 050A
[19/11 13:35:37.743 main]: Built with dvbcsa
[19/11 13:35:37.745 main]: Built without CI
[19/11 13:35:37.747 main]: Built with dvbapi
[19/11 13:35:37.749 main]: Built with AES (OpenSSL)
[19/11 13:35:37.750 main]: Built with tables processing
[19/11 13:35:37.752 main]: Built with satip client
[19/11 13:35:37.752 main]: Built with linux dvb client
[19/11 13:35:37.752 main]: Built with backtrace
[19/11 13:35:37.753 main]: Built without netceiver
[19/11 13:35:38.298 main]: Initializing with 1 devices
Go to http://rpi:8080 I get this:

After a minute it say "OFFLINE":

I am missing something?

How could I search my channels? I want to connect to OSCam too. I search for a configuration examples but I have not found nothing.

I will really appreciate your help.

Kind regards.

Hi,

-o host:ip

is the parameter for oscam.

In order to use minisatip you need a satip client (like tvheadend, vdr or dvbviewer, or some mobile app). They will discover the server and be able to use it. When it requests to tune to frequency, the adapter will be online again.

Thanks

Thanks cata!

I will try it for OSCam, need I install OSCam in localhost? Or I could point to my LAN server?

I have a tvheadend server in LAN but different network. Minisatip is in 192.168.1.0/24 and tvheadend is in 192.168.2.9/24, could this work?

About channels/transponders, is it possible to select some channels or transponders to share? I don't want to share all the channela in satellite.

Thank for your great help.

Best regards.

I think you can define in tvh the satip servers via command line if they are not in the same network.

Also when u define the network in tvh disable network discovery. IN this way only defined TP will be scanned.

Yes remote oscam can be used

Thanks!

It doesn't work with remote OSCam, so I installed in the localhost and point to the remote one, this way it works:

Code: Select all

minisatip -f -o localhost:9000
I notice that I get 100% CPU in the Raspberry Pi:

It happens with encrypted HD channels, with FTA HD channels it takes 50% of CPU, is this normal?

Thanks for your great work and help.

Regards.

HI,

RPI processor is not very fast, that's why you see the high load.

My tests with Cortex A7 (like RPI) shows a high load on the core where the channel is decrypted. A9, A15 or A17 are much faster.

ARMv8 is also much better at decoding (like RPI 3 or RPI v1.2) as the dvbapi library is much faster on a 64 bit processor.

Also you might want to try https://github.com/glenvt18/libdvbcsa/ which might be faster than the default dvbcsa from ubuntu/debian/...

Thanks

Thanks cata,

I will try it in a RPI 2 with libdvbcsa that you pointed.

Regards.
