Bug in output_http.c on HTTP_MAX_QUEUED check
by Konstantin Shpinev 10 Nov '11

10 Nov '11

Hi! I found the bug in file output_http.c at line 109: Code was: if (http_get_queue(hr->hc) > HTTP_MAX_QUEUED) { hr->overflow++; if (hr->overflow > HTTP_MAX_OVERFLOW) output_remove_receiver(hr); return; } hr->overflow=0; Need change to (add "elso" statement after "if"): if (http_get_queue(hr->hc) > HTTP_MAX_QUEUED) { hr->overflow++; if (hr->overflow > HTTP_MAX_OVERFLOW) output_remove_receiver(hr); return; } else { hr->overflow=0; } Otherwise hr->overflow counter is resetting anytime, and condition: if (hr->overflow > HTTP_MAX_OVERFLOW) never happens.

getstream & sasc-ng
by Petr Stehlik 16 Aug '11

16 Aug '11

Hi there, I read through the mailing list archive and noticed several questions regarding the sasc-ng. I was curious myself so I played with it for a while until I realized that in order to decode the channels transparently with the sasc-ng you must use the following switch in the getstream configuration: adapter X { budget-mode 0; } Apologize to those that find it obvious - other guys including myself couldn't read it in the docs so for the record and google I am posting it here. Obviously it would be better if sasc-ng decoded all channels in the transport with the 8192 pid but until someone enhances sasc-ng this workaround helps. Thanks Petr P.S. I am curious what are the differences between mumudvb and getstream - the CPU consumption in the budget-mode 0 is similar between those apps. Getstream has better configuration and can handle more adapters at once. Not sure about long-term stability and scalability yet...

Re: Getstream strange problem.

Dear Peter, 1: We have Televes 17x17x16 Ref. 7345 multiswitch. (you could find its specifications in http://www0.televes.com/inting/producto/catalogos/Multiswitches_Multimat2.p… 5). 2: I could not find any A/B mode on this switch. It has just 17 input (1 terrestrial, 16 for 4 satellites), 16 outputs for receivers and 17 cascade outputs. 3: The strange thing is that my computer works with some multiswitches, and does not work with some others, and I could not find why. 4: I tested with multiswitches from Hirschmann and Finetronics, but both does not work. But it seems some old multiswitches from Triax works very well. 5: You are right. when I use diseqc 0 the diseqc is disabled, but its fine because hotbird is in my input A (or zero) so when I use this multiswitch give position A by default. 6: I've attached my config file. 7: As I said before, progDVB in windows and satellite receivers both work fine with this multiswitch. Even linux scan commands works well, but getstream does not work correctly. I suspect you are right about multiswitch setting, but I could not find anything to adjust. Any suggestions? Also any suggestion about my config file? Any thing I could add to do diseqc manually works with this multiswitch? Best regards. Ali.

Getstream strange problem.
by Ali H.M. Hoseini 22 Jun '11

22 Jun '11

Hi, I used getstream for more than 3 years, and it is a wonderful software, fast and reliable. But now I faced a very strange problem. We moved to a satellite multiswitch for reception. When I scan with option for diseq, everything is OK. But in getstream I Should reverse diseq number to work, and : 1: Everything in port 0 of multiswitch, when diseqc option of config is 0 is works perfectly. (when actually multiswitch is bypassed). 2: Everything in other ports (1-3) works for frequencies in Vertical/High (over 11.7 Ghz, vertical) and Horizontal/Low (under 11.7 GHz, Horizontal) works, and others does not work. 3: When I connect Vertical/Low of LNC to Horizental/High of multiswitch those frequencies start to work in getstream, but I could not scan them anymore. 4: All frequencies work perfectly with satellite receivers and ProgDVB in windows. I concluded that problem is in getstream, but I could not trace its root. Any suggestion? J. Jikman.

Getstream not streaming scrambled channels
by Nima Mohammadi 10 Mar '11

10 Mar '11

Hi there, I use sasc-ng (and dvbloopback) on my computer. I can watch the scrambled channels on Kaffeine and unicast/multicast them using MuMuDVB. Yet when I try to stream the same transponders with Getstream, It seems that the streaming packets aren't descrambled. Also when I set the full pids (instead of a specific pnr) only the FTA channels can be received. The following is my configuration file: http { port 8001; }; adapter 1 { dvb-s { lnb { lof1 9750000; lof2 10600000; slof 11700000; }; transponder { frequency 10949000; polarisation v; symbol-rate 27500000; }; }; stream { name "CH"; input { pnr 7466; }; output-http { url "/ch"; }; }; }; nima@nima-pc:~$ ./getstream -dc ch.conf 2011-03-05 16:29:54.733 fe: Adapter 1 Setting up frontend tuner 2011-03-05 16:29:54.749 fe: DVB-S tone = 1 2011-03-05 16:29:54.749 fe: DVB-S voltage = 0 2011-03-05 16:29:54.749 fe: DVB-S diseqc = 0 2011-03-05 16:29:54.749 fe: DVB-S freq = 10949000 2011-03-05 16:29:54.749 fe: DVB-S lof1 = 9750000 2011-03-05 16:29:54.749 fe: DVB-S lof2 = 10600000 2011-03-05 16:29:54.749 fe: DVB-S slof = 11700000 2011-03-05 16:29:54.749 fe: DVB-S feparams.frequency = 1199000 2011-03-05 16:29:54.749 fe: DVB-S feparams.inversion = 2 2011-03-05 16:29:54.749 fe: DVB-S feparams.u.qpsk.symbol_rate = 27500000 2011-03-05 16:29:54.749 dmx: Setting filter for pid 8192 pestype 20 2011-03-05 16:29:54.782 fe: Adapter 1 Status: 0x01 (HAS_SIGNAL) 2011-03-05 16:29:54.883 fe: Adapter 1 Status: 0x1f (HAS_SIGNAL HAS_CARRIER HAS_VITERBI HAS_SYNC HAS_LOCK) *-- Nima Mohammadi*

FE_CAN_2G_MODULATION
by Igor M. Liplianin 08 Feb '11

08 Feb '11

Hi, It isn't formal patch, just conception how to detect DVB-S2 card. For now it's FE_CAN_2G_MODULATION flag from frontend info capabilities. Current situation leads to delivery system value is taken from frontend cache, where it was from previous tuning. Let's say, create two configs for one DVB-S2 capable adapter, first config for DVB, second for DVB-S2, then start getstream with first, interrupt it, start with second ... Voila! Getstream complains about non-DVB-S2 adapter.

Some crashes with Getstream
by jose＠netlab.tkk.fi 30 Jan '11

Hello, We are using getstream to access the channels of two multiplexes received with two separate DVB cards (Hauppage WinTV 1700) and then publish those with HTTP so then we can use VLC to transcode those channels. The system runs in Ubuntu 10.04 It seems getstream crashes and we got following errors....could you help us indicating where might be the problem?

Lockup of DVB (Technisat Sky Star 2) after multiswitch
by Daniel Gultsch 24 Nov '10

24 Nov '10

Hi, i’m trying to configure my Technisat Sky Star with getstream. I already had this working when i conectet my card directly to one sat layer and turned lnb control off. (We have this LNB which outputs all four layers in different cables). Now we got this multiswitch (With two sat inputs A and B) and everything stoped working. No matter what i configure I always get „dvr: lockup of DVB card detected - trying to reanimate via bouncing filter“. What do i use as the value for diseqc when I want to use the "B" Satelite? 1, 2 or 4??? Do the LNB cut off frequencies have something to do with these error msg? Because I’m not 100% sure I got them right. Does it matter that the multiswitch has diseqc 2.0? Please help - Daniel

FEC for getstream
by Florian Lohoff 30 Sep '10

Hi, i was thinking about FEC (Forward Error Correction) as thats what i heard people use in WAN IPTV Products to protect against low probability ip packet loss. Does anyone of you use something like this today? Does anyone have a client which supports something like this (would need testing) and at which level do you add FEC?
