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

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

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

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
