The most recent project used the big Huan DHQP300 video capture card for video surveillance applications, using Java development, no way, and have to re-encapsulate vendors to provide the SDK, just at the beginning of the use of the image is directly displayed on the computer screen, so there will be a problem, Moving the window when the image will not move, obviously this is not possible, and then re-read the vendor documentation, there is a snap related to the demo, directly to the image to the memory, and then from the memory of the image display to the window, of course, it is very simple, code implementation is encountered a lot of problems, Sometimes all the way to show normal, but four road together when the display garbled, after the help of the technical support staff to find that the multi-channel video at the same time need to be collected image information to be assigned to a different memory address address, so that the four-way video will be normal display, after such a debugging indeed.

Here to highlight, the technical support of the image of the big constant is really too much force.
