Hello,

Running the below instructions as preparation for writing a sequence of images to a video file with OpenCV as framework:

```julia
using OpenCV; const cv = OpenCV
fourcc = cv.VideoWriter_fourcc(*'XVID') 

```

The instruction “fourcc” when compiled gives the following error:

```julia
julia> fourcc = cv.VideoWriter_fourcc(*'XVID') 
ERROR: syntax: "*" is not a unary operator
Stacktrace:
 [1] top-level scope
   @ none:1

```

Any help/direction is appreciated. Thanks.
