The function of PreviewWindow. This article is a summary of the source of their own reading, transfer, please indicate dm6446 source of thank you.

In buffer prior to the completion of the application has the MMAP related operations after executes system calls to the command line, in the command line, mainly completes is DM video vpfe related hardware initialization, Tvp initialization. Complete code download link http: Enter the waiting queue congestion, until the completion of the frame of a data write Oh, the application of the buffer to achieve the column operation.
