Perhaps this tells something to an expert. Each time when I run lavrec ($ lavrec -a 0 test.avi), the following lines are written to /var/log/messages:
DC30[0]: zoran_open(lavrec, pid=[4696]), users(-)=1 DC30[0]: enable_jpg(IDLE) DC30[0]: zoran_close(lavrec, pid=[4696]), users(+)=0 DC30[0]: enable_jpg(IDLE) DC30[0]: interrupts received: queue_state=0/0/0/0: no interrupts detected. What am I doing wrong?
