Platform bug using getstream on ARM
by Stuart Hopkins 26 Jan '10

26 Jan '10

Hi, I've used getstream on x86 platforms for a few years now and have found it reliable and fast, and to that end have just been trying to use it on my Sheevaplug (ARM v5 compatible). I ran into a problem however where no matter what arguments were passed it would error by just showing the options list... It seems that the command line parsing is broken on ARM, and im not sure if its with a library or the check, but if you change below to getstream.c (line 114): while((ch=getopt(argc, argv, "c:dt:")) != -1) { to while((ch=getopt(argc, argv, "c:dt:")) != 255) { it then works correctly and streams data fine. On my little plug PC it uses around 2% when processing all channels on a single DVB mux. Any chance the code can be adjusted/edited to compensate for the check condition, unless 255 doesn't work on x86? Regards Stuart

Problems with Danish MUX2
by Peter Løje 25 Jan '10

25 Jan '10

Hi, I have been using legacy getstream for over 3 years now to stream DVB-T and because of the incredible stability of getstream-20070419.tgz I have not looked much at getstream2. I have been streaming DK MUX1 and 4 MUX's from Sweden without any major playback issues using either VLC on a PC or an Amino-130 Set Top Box. A couple of months ago a second Danish must carry MUX was started (MUX2) and all 5 channels are MPEG-4. 4 channels are SD and one is HD ("DR-HD"). When streaming DK MUX2 with getstream-20070419 I get these results on the client side: VLC-1.0.3 on Win XP will display video but there are no sound. Amino-130 will show 2 secs of video then 3 sec of black screen complaining about changed PMT. No sound. When streaming DK MUX2 with getstream2-20081204 I get these results on the client side: VLC-1.0.3 on Win XP will display SD channels perfectly with sound. VLC-1.0.3 on Win XP will display DR-HD video and sound but sound is rather bad. Amino-130 will still show 2 secs of video then 3 sec of black screen complaining about changed PMT. No sound. Using VLC-1.0.3 to stream from same Linux server as above I get these results on the client side: VLC-1.0.3 on Win XP will display all channels (SD+HD) perfectly. Amino-130 will display all channels (SD+HD) perfectly. How do I best approach this problem? Is it a missing stream type in pmt_mapstreamtype()? What kind of debug information is reqired? Thanks for a great piece of software! Best regards Peter

[BUG] Pat table lost PMT-pid
by Sergei Gurjev 17 Jan '10

17 Jan '10

Hi, I have problem with getstream. After long time of working, getstream sending stream with all needed pids, but pat-table sends without pmt pid. Here is example of UDP-stream dump with PNR=1 and PMT=4110 Broken stream: http://magnus.wnet.ua/dump_notworking.ts After restarting of getstream: http://magnus.wnet.ua/dump_working.ts Here is VLC log of broken PAT: [00000427] ts demux debug: PATCallBack called [00000427] ts demux debug: new PAT ts_id=0 version=0 current_next=1 [00000427] ts demux debug: * number=1 pid=0 Here is VLC log of good PAT: [00000427] ts demux debug: PATCallBack called [00000427] ts demux debug: new PAT ts_id=0 version=0 current_next=1 [00000427] ts demux debug: * number=1 pid=4110

Re: Getstream starts to become unresponsive to HTTP requests after a few days

Hi, Seems I got the copy/paste wrong: wget localhost:8000/test --2009-11-09 18:25:13-- http://localhost:8000/test Resolving localhost... 127.0.0.1 Connecting to localhost|127.0.0.1|:8000... connected. HTTP request sent, awaiting response... lsof does show 900+ connections to port 8000, so it would seem getstream isn't able to detect when someone disconnects from a http stream? (There is at most, 5 concurrent viewers at a time).

How one could check if udp-stream is beeing received ?
by Y.Bosco 29 Nov '09

29 Nov '09

Hi, There are a server where getstream is running and a client computer where some client software is displaying a TV channel. The system was made according to Ivan Murashko's advice: Ivan Murashko <ivan.murashko(a)gmail.com> Y.Bosco <openboelru(a)pochta.ru> getstream(a)gt.owl.de Re: HTTP output 28.07.2009 14:36:02 Within some minutes (from 1 till 30) from the start the displaying process is interrupted. In other words the movie becomes a still picture. But getsream continue multicasting, udp-packets continue filling the net. If you try to disconnect from the stream (push button "Stop") and then connect to it (push button "Start") the movie will continue. It would be very useful to automate such process. But how one could understand that an udp-stream is interrupted without looking at the screen? Is there any detector(s) in the operation system? -- Mr. Yourij Bosco Bosco Electronics http://boel.ru +7-495-727-6038

Getstream starts to become unresponsive to HTTP requests after a few days
by James Creese 09 Nov '09

09 Nov '09

Hi, We run getstream on a mixture of DVB-T and DVB-S servers. We experience the weird problem where after a random amount of time (always more than a couple of days) you just are unable to connect to HTTP any more. Getstream is still running it's just you're unable to connect to the streams. Has anyone encountered this problem, or seen in the source code as to why this might happen? Thanks, James

Re: 2 multiplexes on the same frequency?

I misunderstood, as they listed the channels but not frequencies. Regards, Chris

2 multiplexes on the same frequency?
by Chris Hills 30 Sep '09

30 Sep '09

Hi I am using getstream for home use, and it is great! On 1st November a new multiplex will be transmitted in Denmark. According to the list at http://www.digi-tv.dk/Indhold_og_tilbud/frekvenser.asp it will use the same frequency as the first, but a different channel (29 vs 57 on Nibe-Tolne). How should getstream be configured to pick up either multiplex? My current configuration is as follows:- adapter 0 { dvb-t { frequency 538000000; bandwidth 8; transmission-mode auto; guard-interval auto; hierarchy none; modulation auto; }; [..] }; Regards, Chris Hills P.S. There is a stream report from dk-mux-1 at http://www.chaz6.com/files/dk-mux-1.html made with TSReader. A longer configuration is available from http://www.chaz6.com/files/config-dvbt-dk-9220.conf

Downscaling questions
by Ron van Herk 18 Sep '09

18 Sep '09

Hi, Is there a way to downscale the bitrate for individual http output channels (from dvb-S source) ? Or even downscale all the outgoing http stream bitrates? Best regards, Ron
