Tvheadend running but ports 9981 9982 closed
Hi, I was wondering if anyone has any idea how I could determine the cause of my problem with tvheadend. I installed the hts-tvheadend package on ubuntu minimal 10.10 from ppa:lars-opdenkamp/xbmc-pvr. After restarting the system I see that the tvheadend process is running but I cannot establish a connection to http://localhost:9981. BTW, I do all the tests on a single machine so there shouldn't be any problem with the firewall. Furthermore, when I run 'netstat -an' the ports (9981, 9982) used by tvheadend do not appear in the list of open ports (actually netstat does not report any tvheadend related ports).
Actually, initially I tested my system with VDR 1.7.16 + VNSI + XBMC 10.0 and everything was working fine (except the stability problem most probably caused by VNSI), but now I wanted to give tvheadend a try. But since the VDR + VNSI + XBMC configuration was working ok, I would assume that the necessary hardware drivers are loaded correctly.
Did any of you came across a similar problem, i.e. tvheadend process is running but neither the 9981 nor the 9982 port is open? Alternatively, if I post a tvheadend debug log, could it help to track down the problem?
Edit: OK, syslog says "comm: tvheadend Tainted" and the ps command shows tvheadend as [defunct]. I think I will have to debug tvheadend in order to figure out what goes wrong and why tvheadend dies :-(
Edit 2: To give some background info first: I installed the latest mercurial s2liplianin driver since my Tevii S464 PCI card wasn't initially supported by the kernel in Ubuntu 10.10.
After debugging a few minutes, I got a bit further with this but still don't have a clue what the problem is. Things go wrong in the "v4l_adapter_check" function, specifically when the statement "r = ioctl(fd, VIDIOC_QUERYCAP, &caps);" is executed. So, the V4L driver might cause the problem, or at least it seems to be related to it.
If you build the source yourself you can do

Thanks a lot. Using the --disable-v4l option and compiling afterward did the trick.
BTW, can you please tell me what the advantage/disadvantage is to have v4l enable or not.
