Frontends cannot be opened in RW mode

[marian34]

Otherwise on SH4 enigma is quite a problem. Drivers work, but it is not foolproof. E.g. logic tuner is there some inoperable.Frontend1 tune is really a problem.
It can in fact spend a lot of time without a successful outcome.


Otherwise, this technology really like. But for others it may be dangerous, e.g. manufacturers of DVB cards.

How is it with minisatip for clear channels?

Does it work or there are issues?

Btw use --dmx-source 0:0 --dmx-source 1:1

[marian34]

Hi cata,

fta channels they are alright, It may not be used -o switch.

Thanks

btw, see this discussion about dvbcsa speed

https://github.com/perexg/satip-axe/issues/17

I hope to get enigma on my receiver too and then I can test more...

Try the last minisatip and the oscam from: http://shivanet.ro/tmp/oscam-1.20-unsta ... -gnu-stapi

Might work just a encrypted channel from one adapter...

Hi cata,

thanks.

Support stapi(oscam) not necessary. It's reader support. But I use those for which the link.

Last minisatip work, but not reliably. Especially when switch to another transponder (only in terms of coded channels).
A DVB-S(23,5-12070H) transponder can not open at all. Neither uncoded channel on this transponder.

I see the same issue in minisatip as I see in the oscam logs: Too many open files.

You might want to try before starting minisatip:
ulimit -n 1024

Also check this link:
https://easyengine.io/tutorials/linux/i ... les-limit/

Just for the reference I have disabled enigma from /usr/bin/enigma2.sh by adding the following lines after datarootdir=....

Code: Select all

if [ -f /home/root/no_enigma ]; then
if [ `ps ax|grep minisatip|grep -v grep|wc -l |awk '{print $1;}'` -gt 0 ]; then
exit
fi
if [ `ps ax|grep oscam|grep -v grep|wc -l |awk '{print $1;}'` -eq 0 ]; then
oscam -c /usr/keys/oscam_emu_modern/
fi

killall enigma2
killall minisatip;sleep 2
>/tmp/minisatip.log
cd /home/root
./minisatip -l -l -l --dmx-source 0:0 -o /tmp/camd.socket
exit
fi

and then
touch /home/root/no_enigma

My dvbapi configuration:

Code: Select all

[dvbapi]
enabled                       = 1
au                            = 1

The problem persists.If minisat started with the -o, DVB-S(23,5-12070H) transponder can not open at all. Neither uncoded channel on this transponder:

minisatip.zip

minisatip_not_open

(9.51 KiB) Downloaded 410 times

If minisat started without the -o, uncoded channels opens immediately.

Other transponders quite ok. The program always opens up for the second time(when switching to a different transponder):

Hi,

the problem with 12070 is that you have alot of PMT pids, and after 27 pids opened it fails.
This makes me think there is a limitation of 32 pids somewhere.

By trying a clear transponder where there are alot of radio channels (12363) I can see the same issue.

I saw that I could add multiple filters without opening the file multiple times, but I need to test if this works on non-enigma DVB cards.

Thanks

Check the latest commit, it limits the number of open pids on SH4 platform to 20.

For me, once I was getting the error, I could not use minisatip fully until restart (I was not receiving data on some filters).
