Description

I use tvheadend latest from the git.

And it work ubnormal with this card:

First bug:
If I want to scan S2 transporder, i must first scan any dvb-s transporder on card. Otherwise i will have too much "Continuity counter error" And TV stream is brocken.
After scan dvb-s, scan any transporder dvb-s2 work fine - stream work stable.

Second bug:

After some time transporder stop working, in syslog i have:

Apr 30 04:16:04 localhost kernel: [104293.085628] TurboSight TBS 6984 Frontend:
Apr 30 04:16:04 localhost kernel: [104293.085630] tbs6984fe - Current Delivery System and Mode are unknown

when i try to watch TV stream from tvheadend.
But in tvheadend in "multiplexes" menu shows "Frontend Status" - "Ok"

Dvblast work fine. (I take UDP and send it for tvheadend, and testit - all fine )

I found this problem in getstream.a84 https://cesbo.com/boards/1/topics/231 ( but sorry - on russian )
They make patch for getstream.a84, and all work fine :

diff r f78fe4ebc1a6 fe.c
-- a/fe.c Thu Feb 09 10:40:08 2012 0600
++ b/fe.c Thu Feb 09 11:08:23 2012 0600

p7.cmd = DTV_TONE; p7.u.data = tone;
}
p8.cmd = DTV_TUNE; p8.u.data = 0;
- p9.cmd = DTV_MODULATION; p9.u.data = QAM_AUTO;
// p9.cmd = DTV_MODULATION; p9.u.data = QAM_AUTO;

- cmds.num=10;

cmds.props=p;

if (ioctl(adapter->fe.fd, FE_SET_PROPERTY, &cmds) < 0) {

I have the same card, and do not have this problem. use the latest git source and try to change the irq setting in the BIOS.

It is imposible to change IRQ.

What is motherboard and chipset did you have?

And what kernel did you use ?

#3

Updated by none none over 12 years ago

And after I restart tvheadend - all again work fine.

Updated by Hein Rigolo over 12 years ago

so? close this ticket?

Hein Rigolo - tvheadend on TBS lost transporder and in syslog I see

Apr 30 04:16:04 localhost kernel: [104293.085628] TurboSight TBS 6984 Frontend:
Apr 30 04:16:04 localhost kernel: [104293.085630] tbs6984fe - Current Delivery System and Mode are unknown

after two, three days. So - too fast.

I use for test - dvblast - and with dvblast all work stable.

Maybe, after some time, tvheadend make not correct reinit frontend? And driver write it in syslog.
After I restart tvheadend all work again a couple of days.

hi, do you still have this issue? I am getting the same errors using the card with tvheadend. I only noticed it on the BBC HD channels on 28.2E (10847V 23000 8/9 DVB-S2).

I see this in dmesg when the error occurs

[93355.176275] TurboSight TBS 6984 Frontend:
[93355.176278] tbs6984fe - Current Delivery System and Mode are unknown

And some times even though pc hasnt restarted I see:

[91618.514220] TurboSight TBS 6984 Frontend:
[91618.514222] tbs6984fe - software version is 1.95.2.3
[91618.514225] TurboSight TBS 6984 Frontend:
[91618.514226] tbs6984fe - Successfully Initialized

Would like to know if its just a tvheadend issue before i return card

still have this issue :(
Latest kernel 3.4.4 64bit (fc16)
Latest driver from tbs.

I solve this problem with dvblast.
Dvblast -> udp with -W -Y opt to multicast.
And tvheadend decode multicast on demand.

But old cards skystar2 works fine :(

This card is known to work by several TVH users, however it needed a patch I supplied some months back.

I'm having problems with this card also.
Can you please point me to that patch you supplied ??
And if possible... a little help on how to apply it...

Thanks

The patch was applied months ago and related to S2 configuration. However other users are experiencing other issues with this card that are being discussed on the forums (might even be an issue in for it).
