Bug #2468
IPTV issue
100%
Description
Hi,
IPTV channels are working all OK. I'm able to view them on different devices by using VLC, XBMC, Plex, etc.
But there's an issue. If I'm watching IPTV channels on several devices at the same time and one of the devices stops watching a channel, IPTV streaming is stopped on all other devices as well...
If I start watching any channel on any device again then streaming resumes on all other devices.
It looks like stopping one channel stops all streams and unsubscribes from all multicast packets.
Any ideas? 'Status' page is showing 0 for 'Input' and 'Output' columns.
TvHeadend version - 3.9.1977~gd347c3d~trusty on Ubuntu Server 14.10.

Updated by I thought that it's an issue with router but udpxy is working without any issues. I can watch IPTV channels on several devices at the same time and closing stream on one device does not stop other streams.

No, all IPTV channels have different IP addresses - udp://@239.2.3.11:1234, udp://@239.2.3.12:1234, udp://@239.2.3.13:1234, etc.
I tried to change udp://@239.2.3.11:1234 to udpxy address http://192.168.0.xxx/udp/239.2.3.11:1234, but result is the same. If I stop one stream, then all streams stop as well..

The UDP is one-directional without any "close" notifications to the server.. Could you check, if subscribed multicast groups persist for "not closed" streams ?
netstat -g
With all streams and with one stream unsubscribed...

- File netstat.txt netstat.txt added
See attached for log. It looks like it's unsubscribing from all streams..
Lines 4 and 5 are IPs for channels.

No idea - the UDP multicast socket should be closed using the close syscall and kernel should remove only IGMP membership related to the IP address assigned to fd.

Updated by This happens with HTTP sources too. If you open two channel URLs in VLC, then stop one of them, the other one will die a few seconds later and "Stop streaming <channel>, timeout waiting for packets" will show up in the log. This seems to be a fairly recent regression since I can't remember seeing it before.

To add to my last post, the HTTP sources I noticed this issue with came from a custom software that restreams video as MPEG-TS so that tvheadend can read them. No multicast is involved at any point.
@perexg is there some additional information you'd like me to provide?
