Hi
I am calling a subvi that
contains 2 media player controls that are sync'd together, one playing
video and one playing audio as the audio is stored in a separate file.
The first time the main vi calls the subvi, the video plays with no
problem. The second time the main vi calls the subvi, the video plays
but with a black screen (still plays through the length of the file
just cant see anything).
After the main VI is closed
and re-run, it can then call the subvi once correctly, then once again
the next time the subvi is run, the screen is black .. and so on.
When
just running the subvi on its own (not called by another VI), this
problem does not occur. I am closing the references to the players and
using the request deallocation function in the subvi, but still no joy.
any ideas?
