Hi Andrew,
Currently there isn’t a way to open multiple hands of a
file, but there are several ways of getting around it. One way
to avoid this error is to place the IMAQ AVI Open before your while loop. That way you can read or write multiple times
but you will only open the file once. If
you are doing parallel loops you can take the reference from your IMAQ AVI Open
and wire into both of your loops and do your reading inside of the loops. If it
is necessary to Open your file multiple times then you will need to make sure
that you close the AVI file before you open it again. Including an Open and Close inside of your
while loop will cause the program to run much slower, so if possible only do
reading or writing inside of your while loop. I hope this helps. Keep me posted if you have any more
questions.
Have a great day,
GG
