Hello Developers,
I receive kernel oops messages after including alsa sound api functions
in my program wich receives and displays videostreams from two ieee1394
videocameras with libdc1394.
videostreaming and alsa audio output work fine on their own, but together it
seems as if the dma-controlling becomes somehow confused on the kernel-level,
upgrading from kernel 2.6.5 to current 2.6.10 did not help.
my program runs for about 1 second before it crashes with
(dc1394_capture.c) VIDEO1394_IOC_LISTEN_WAIT/POLL_BUFFER ioctl failed!
(dc1394_capture.c) VIDEO1394_IOC_LISTEN_QUEUE_BUFFER failed in done with buffer!
segmentation fault
and the kernelmessages as shown in the attachment.
trying to start my prog again fails - only reboot enables the program to run
briefly again.
unfortunately i cannot send my two cameras with this mail to try out the
problem ..
greetings,
alex
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
