A customer of mine in Colombia has integrated their application with the MCA to embed camera functionality. THey have developed using the MCA SDK. Everything works great, except that the preview times out at random intervals. It is set ot 15 seconds in the MCA Config, but in practice, it is sometimes 15, sometimes 2, or 8. The timeout period experienced does not follow a pattern - that is, iot does not get progressively shorter, for example. It seems wholly random, but not more than 15 seconds.
Is the code below that is used to implement the function flawed?
