[mythtv-users] HELP: System crash when trying to watch live or
cctsurf at hotmail.com
Wed Oct 19 23:05:55 EDT 2005
Having lurked for a while and searched threads for help with my situation, I
could not find any threads that would help me... Perhaps I have overlooked
something, in that case, forgive me and please point me in the correct
direction. I am somewhat of a Newb, especially in matters of v4l/mythtv. I
am running Gentoo unstable tree. (~x86)
Notably it seems that I can record because I can see the show previewed in a
small window (in my theme, below the listing of recorded shows) before
attempting to watch it (I haven't been able to play recordings using Myth or
mplayer, either with transcoding (mpeg4) or without - straight .nuv file)
When I attempt to play back the recording with Myth, I get a lockup, with
Mplayer, I get some attempt to load codecs, but it exits very quickly.
After a mythtv lockup, I cannot do anything but
reset the system, SSHing in doesn't work (in fact, I often have to reset
twice to get a boot).
I assume that I could have a problem with my sound (sblive), but I have at
times disabled it (mythtv asks if I want to proceed without sound (I had
difficulty initially getting the sound devices to be rw for users on
reboot), and when I proceed, it crashes the computer in the same way that it
did with the sound enabled (perhaps this is just the fact that myth crashes
without sound working).
I captured this through a ssh connection:

2005-10-19 02:58:27.514 Realtime priority would require SUID as root.
What is going on at the time of the last line? I assume that that would
point to what is crashing the system. Also I note that I don't think XV
works for playback in Mplayer, could this be causing the crash.
Once again, I know it doesn't mean anything, but I can watch tv through all
of the normal tv viewers and listen to music from the radio on the card, I
can even listen to mp3s on Myth,
I am running on older, somewhat thrown together hardware, so the problem
could arise from something there Below is a list of the Hardware in the
Mboard: Tyan Tiger 133 (Dual P3, VIA Apollo Pro 133A (VT82C694X) chipset)
Memory: random manufacturer(cheap), 512mb
Video: ATI Rage 128pro AGP
TV Card: Sabrent SBT-TVFM (using Philips SAA7130 (7134) chipset)
USB Card: Sabrent SBT-ALI5Y --needed faster access to my usb hard-drive,
haven't had time to
really get this working.
Network Cards (this system acts as wireless router/dns for my wired
Dlink DWL-G510, using ndiswrapper
SCSI - Ancient Advansys ultra-scsi-2 - Don't remember the exact number.
I have only one shared interrupt, of pretty much unrelated hardware.
Is there a better way to debug my problem using gdb? I have tried, but I
don't quite understand how to use gdb. Also, the whole idea of segfault is
confusing to me, am I correct in thinking I don't have that problem? For
gdb, I would appreciate exact commands. Thanks
My guess is that I have some sort of heavy processor load (possibly
searching for sound or something like that) causing this lockup, but I'm not
running from a root/su environment.
Thanks in advance!
