Hi,
I have had this problem several times. I have systems with 5 capture cards
in them that need to pull cc data 24hours a day. Everything works fine for
about 48hours until the ccdecoder processes start to die. When I try to
restart them by running:
[root@lga1 bin]# /usr/local/bin/ntsc-cc -c -p -d /dev/vbi3
/dev/vbi3: Cannot allocate memory
Unloading and reloading the modules does NOT fix this. The only solution I
have been able to find it to reboot the PC. Also I find when it happens to
one capture card in the pc, it also happens to several others within a short
period of time, but not always all of them. Has anyone else seen this
problem?
systems have 5 ATI-TV Wonder cards
bttv-0.8.31
CCDecoder 0.9.1 (encluded with xawtv)
Thanks,
Jon
