[MEncoder-users] mplayer/mencoder tv:// reboots my computer

[Pepe]

Very strange thing.

I'm trying to watch tv using mplayer. It seemed to be working ok, but then 
suddenly when I typed again the command to watch another channel (mplayer 
tv://8) and pressed enter, my computer reboots!

That was yesterday. Now I tried again, mplayer seemed to work with all 
channels so I tried mencoder. I typed the command and press enter. No output 
on the console... one second later my computer reboots again.

My TV card is a Best Buy BT878.

Config:
tv=driver=v4l2:input=0:width=768:height=576:device=/dev/video0:audiorate=48000:n
orm=PAL:chanlist=europe-west:channels=46-TVE_1,43-La_2 (and so on)

MPlayer 1.0pre8-3.3.4, SuSE 9.2 with kernel 2.6.8-24-default

mencoder command:

mencoder -o video.avi \
  -oac mp3lame -lameopts vol=0:mode=3:cbr:br=64 \
  -ffourcc DX50 \
  -ovc lavc \
  -lavcopts vcodec=mpeg4:vbitrate=1200:mbd=0:vstrict=1:vqmax=31 \
  -vf-add scale=576:432 -zoom \
  tv://2

Other TV applications like xawtv or kdetv work ok.

If I use "driver=v4l" instead of v4l2, mplayer segfauls:

Playing tv://1.

MPlayer interrupted by signal 11 in module: free_demuxer
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible 
bug.


Any ideas?
