Description

First let me say that I find it a wonderfull program.

Has any one had problems with tvheadend and some port numbers.

I have Ubuntu 10.04 with Tvheadend running. If I add a list of UDP addresses then only the addresses with port number 1234(udp::1234) are working. Addresses with port numbers of 5 digits do not work udp::10294

Strange thing is that when I watch these streams straight with VLC it is fine(same PC), but if I click on play in the tvheadend webpage and then select VLC to play it doesn't.

I made some traces with Wireshark to see what is happening, the request for the stream is being sent, the stream is also being sent but tvheadend is not picking up this stream.

Dear Andomal,

See below the output when I try to start 5 port digit.
[email protected]:~$ sudo netstat -anp | grep tvheadend
tcp 0 0 0.0.0.0:9981 0.0.0.0:* LISTEN 1131/tvheadend
tcp 0 0 0.0.0.0:9982 0.0.0.0:* LISTEN 1131/tvheadend

unix 2 [ ] DGRAM 5845 1131/tvheadend

Thanks,

Dear Andoma,

Just installed ClearOS 5.2 had the same issue the udp's with 5 digit port do not work.
ClearOS I saw which port were opened on a request. See findings below:

udp::1234 working

source dest port
82.139.121.42 239.193.128.110 1234->1234
10.252.164.177 239.193.128.110 38->1216

udp::10294

source dest port
80.79.34.85 233.81.233.161 60000->10294
10.252.164.177 233.81.233.161 18->576

Hope this helps, if I need to try something then please let me know.

Thanks

Hi,

I've noticed this also with the latest version from git. Recording both SD and HD into .mkv from a channel on port 1234 works fine. It seems that registering a channel with a 5-digit portnumber fails, because the contents of ~/.hts/tvheadend/iptvservices/iptv_... for the 5-digit config does not contain stream sections.

Some debugging showed that the socket is opened correctly though, and multicast membership is added.

Could the cause be because some IPv6-sanitizing function is called on the IPv4 address with the portnumber? I.e. where only four digits are allowed after a colon?

  • Status changed from New to Fixed
  • Target version changed from 3.0 to 2.13

The problem was a bug in the IPTV PAT parser. The parser only parsed one entry in the table (we only support one service per IPTV multicast group anyway). Problem was that some providers sends a dummy first entry with service_id == 0, if we skip that it seems to work OK
