Unicast streaming
by Дмитрий 22 Sep '10

22 Sep '10

Hello. What about unicast streaming channels per ports? For example: stream {name "Dom Kino"; input { pnr 1; }; output-udp {remote-address 239.0.0.12; remote-port 1234; sap{scope global; ttl 5;};}; output-http {unicast-address 192.168.0.1; unicast-port 8012;}; }; And playing it with vlc http://192.168.0.1:8012 I hope it is very usefull. Thansk for all!

I am using PCIe cards from TBS: ib-technology.de Work fine, 3 cards in one PC, twin tuners so they give 6 tuners.

They can stream the whole transponder. Drivers I think are included in 2.6.34 and up but if you are running lower you'll have to compile the linuxtv module which is what I've done. Si.

Nice home application! ;-) But doesn't Multicast provide some kind of IGMP client registration? If you close the Linux DVB-API file-descriptor of a DVB-card it's powered off - saves about 20W with older cards. >> Is DLNA not the scope, too?

If the clients can handle the A/V-codecs, containers and multicast you just have to demux the bouquet in the TS (and maybe adjust PIDs). DLNA means providing a XML-file with service descriptions via HTTP. From the author of the VDR-DLNA-Plugin (http://projects.vdr-developer.org/projects/plg-upnp/wiki) I know there are already standardized service descriptons for DVB. It would allow to use cheap consumer Media-Players, DLNA-capable-TVs, XMBC and Windoze Mediaplayer. And nothing to configure on the client - just plug&view! > Its a unix tool - small swiss army knife - dont overload with feature.

Simple and efficient are the world which cause my interest in getstream. I don't like MythTV! Who needs a XServer + OpenGL GUI on a server? That's why I'm looking for a rock-solid multi-transponder DVB-Multicast-Gateway with DLNA-announcement for LiveTV and a additional PVR-Box using that gateway. ;-) Renne

Is DLNA not the scope, too? It allows continous streaming to TVs/Mediaplayers and is just a slim aggregation of Multicast/Unicast RTP and Announcements.

That's what I'm looking for! ;-) Headless low power DVB->DLNA-Multicast-Gateway feeding EIT/EPG into a database. A PVR-server would just use DLNA/HTML5 to provide EPG and recordings. But instead of netcat for recording I suggest a multithreaded recording process listening to "EIT running status" (with timer-fallback in case of unreliable TV-stations). Renne

Dynamic usage of DVB-cards/DLNA/EPG
by Rene Bartsch 16 Sep '10

16 Sep '10

Hi, I just found the Getstream Website! :-) Does Getstream support: - Dynamic usage of DVB-cards (waiting for the first Multicast-/HTTP-request of a bouquet and using the next available DVB-card/freeing DVB-card after all connections disconnected)? - DLNA-announcement (useful for DLNA-capable TVs/Media-players)? Which format does the EPG-data have in Pipe? Is it possible to use (x)inetd to get EPG-data of all tuned DVB-cards via TCP? Best regards, Renne

S2 PCIe card recommendation
by Maik Musall 08 Sep '10

08 Sep '10

Hello, I have a small server with already 4 PCI TT-budget cards, running getstream. I'd like to serve more streams, but there are no free PCI slots left. However, I have 3 PCIe slots free there. Secondly, I'd like to stream S2 as well. What cards can you recommend that I can use to stream a full transponder with getstream and which are PCIe and can do S2 (I could do without S2 if nothing else fits). What about TeVii S470, for example? Thanks -- Maik Musall <lists(a)musall.de>

Link with --as-needed option fails
by Vitaliy Tomin 16 Aug '10

16 Aug '10

Current getstream fails to link when compiling with --as-needed gcc option. This happens because libraries to link defined before objects, but --as-needed requires objects then libraries to link. I suggest small patch for Makefile: all: getstream tsdecode tsdecode: $(OBJ-tsdecode) - gcc $(LDFLAGS) -o $@ $+ + gcc -o $@ $+ $(LDFLAGS) getstream: $(OBJ-getstream) - gcc $(LDFLAGS) -o $@ $+ + gcc -o $@ $+ $(LDFLAGS) clean: Some reading about --as-needed : http://www.gentoo.org/proj/en/qa/asneeded.xml By the way, latest getstream packages for openSUSE 11.1, 11.2, 11.3 in my buildservice project: https://build.opensuse.org/package/show?package=getstream&project=home:High… and repository: http://download.opensuse.org/repositories/home:/HighwayStar:/sandbox/

Patch for logging to syslog + Autorebouncing if no stream
by Михаил Продан 20 Jun '10

20 Jun '10

1. Thanks Florian Lohoff <f(a)zz.de> for suggestion about syslog logging there is a patch for that (if you need one) 2. What is Autorebouncing? Very often my getstream produces this kind of output (for number of simultaneus channels > 6): 2010-06-19 19:54:40.399 fe: Adapter 7 Status: 0x1f (HAS_SIGNAL HAS_CARRIER HAS_VITERBI HAS_SYNC HAS_LOCK) 2010-06-19 19:54:45.279 dvr: inputstats: 31 pids 44876 pkt/s 8436763 byte/s total pkt 224382 total size 42183816 2010-06-19 19:54:50.282 dvr: inputstats: 31 pids 6055 pkt/s 1138490 byte/s total pkt 30279 total size 5692452 2010-06-19 19:54:55.291 dvr: inputstats: 0 pids 0 pkt/s 0 byte/s total pkt 0 total size 0 2010-06-19 19:55:00.335 dvr: inputstats: 0 pids 0 pkt/s 0 byte/s total pkt 0 total size 0 2010-06-19 19:55:05.355 dvr: inputstats: 0 pids 0 pkt/s 0 byte/s total pkt 0 total size 0 ...... As you can see inputstats are empty The only thing that helps me - restart of getstream. This patch invokes rebouncing when inputstats becomes 0
