Software descrambling with oscam on adapter grather then 8 about mumudvb

[ostryck]

As I've already told You mumudvb is not getting any messages from oscam despite sending correct capmt for those adapters so it's oscam issue.

[mcwago]

no its not oscam issue,
ERRO: SCAM_DECSA: thread starved
there is some bug in the code of mumudvb, i have
1.7.1_20121001_scam working fine
1.7.2_20130915_master working only autoconf with error "thread starved"
libdvbcsa-1.1.0
i think there may be some problem with communication between mumu and libdvbcsa.
I can send you debug, but tell me what you need.

[ostryck]

are you sure that, you're reffering to the same bug as petarslavnic ??? For no autoconfigurated channels I've pushed to my repo temporal fix https://github.com/ostryck/MuMuDVB

[mcwago]

ok, patched 👍
but, the error persist:

Sep 30 20:58:30 streamer MUMUDVB[9618]: ERRO: SCAM_DECSA: thread starved, channel channelname6 0 0
do you know what does it mean?
i havent this error on older version.

[ostryck]

it's normal on startup due to recent change of when mumudvb threads connected with software cam get started. As long as they don't persist later you're good to go, I'll take care of that soon.

[petarslavnic]

So if I understand there is problem only with auto configuration, am I right?

[ostryck]

no, mcwago had different kind of problem, not in any way connected with more than 8 adapters. Due to recent change(2 weeks old) of how ca_indexes get mapped to mumudvb channel, software cam was not working with disabled autoconfiguration.

I have the same problem, 12 adapters with same configuration of mumudvb
1-8 are working fine
the 8th and above, does not decrypt

[mcwago]

post config, channel part here, like
autoconf_sid_list=711,...

#CHANNEL HD
new_channel
service_id=711
ip=239.255.0.30
oscam=1
ring_buffer_size=32768
decsa_delay=500000
send_delay=1500000

and version u r using
did u patch kernel for more the 8 cards?
also, MAX_DEMUX for oscam source?
post your os spec, kernel uname...

[byte123]

All cards are TBS6985, and are working fine on FTA channels

This is the config file, that I am using (only changing card numer)

When I change the cards order on the mainboard ( dvb8 become dvb0 ), the mumudvb is working.
I had tested it with Mumudvb 1.7.3 and 2.0.0 ( 20150614 )

My problem gone with older oscam change,

What cas system u have? Viacess, irdeto, seca....? Do u have local card, or remote share? What is your decoding time, look in live log in oscam.

[byte123]

I haven't pached my oscam.
Which version do you use ?

[mcwago]

no matter which version, use latest from repo
svn checkout http://www.streamboard.tv/svn/oscam/trunk oscam-svn
cd oscam-svn
manualy patch

Note from mumu doc:
When using oscam with more than 16 channels adjust macro definition MAX_DEMUX (line below) on oscam header module-dvbapi.h to number of your channels
#define MAX_DEMUX 16
finaly ->
make

[byte123]

OK, which patch ?
