I have a PVR-500 in a machine here where one of the /dev/video* devices
can successfully be opened and return data while the other can be
opened but returns to data to a read(2). i.e.:
open("/dev/video3", O_RDONLY|O_LARGEFILE) = 3
dup3(3, 0, 0) = 0
close(3) = 0
fstat64(0, {st_mode=S_IFCHR|0660, st_rdev=makedev(81, 11), ...}) = 0
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfc7f568) = -1 EINVAL (Invalid argument)
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7423000
read(0,
and the process blocks there.
Any idea why this might be happening? Kernel is 3.2.0-33-generic which
I believe is 3.2.1 based.
