Exception when passing ByteBuffer to texture #1

Open ayberkozgur opened 10 years ago

In the desktop application, when passing the ByteBuffer that contains the camera image to the Texture, the following exception occurs:

Exception in thread "LWJGL Application" java.lang.IllegalArgumentException: Number of remaining buffer elements is 921600, must be at least 921600. Because at most 921600 elements can be returned, a buffer with at least 921600 elements is required, regardless of actual returned element count

It may be an out of memory issue or a lock issue with the ByteBuffer. Will see if mutexing the ByteBuffer solves the issue.
