Recently, we used Intel's media SDK to play H264 videos. We found that the frames transcoded by intel's SDK are in the NV12 pixel format and must be converted to the RGB32 format by ourselves. Although this type of code looks for a lot on the Internet, you can do it yourself. Google's conversion formula: C = Y-16D = U-128E = V-128R = clip (round (1.164383 * C + 1.596027 * E ))G = clip (round (1.164383 * C-(0.391762 * D)-(0.812968 * E )))B = clip (round (1.164383 * C + 2.017232 * D )) I studied h

The command format is as follows: 　　 # Mdadm-Cv/dev/md0-l5-n3-x1-c128/dev/sd [B, c, d, e] 1 　　 The parameters in the Command indicate the following functions: "-C" indicates creating a new array, "/dev/md0" indicates the name of the array device, and "-l5" indicates setting the array mode, you can select 0, 1, 4, 5, and 6, which correspond to RAID0, RAID1, RAID4, RAID5, and RAID6, respectively. Here the mode is se

Run the fdisk command to create a partition. # fdisk /dev/sdb After entering the fdisk command line, Run Command n to create a partition, command t to change the partition type, command w to save the partition table and exit, and command m to help. 2.

The other four disks are divided into only one primary partition, /dev/sdb1,/dev/sdc1,/dev/sdd1,/dev/sde1, and specify the partition type as "FD ", this will enable the Linux kernel to recognize them as raid partitions and automatically detect and start each boot.

Pagedatasource is Microsoft to provide a class for paging use, the integration of some of the methods of binding controls, in use, we only need to read from the database we want the data, binding to Pagedatasource, Then allow Pagedatasource to page, specify the current page and the number of pages to display, so that you can get a good total number, combined with the control, viewstate can complete the custom paging view, as follows: PagedDataSource Pagedatasource = n

Whether it's windows or iOS, there are countless products that have tried to compete with Microsoft and Apple before they succeed, but they have certainly contributed to today's pattern, to see the 11 forgotten operating systems. 1.ms-dos Listing Time: 1981 Developer: Microsoft If you have an IBM PC in the 80 or early 90,

port, and an Ethernet cable into an Ethernet port. Optical discs are read using lasers to read data from a reflective surface of a laser that can be scattered or reflected, and a common disc is a DVD. Many systems say they are 32-bit or 64-bit, which refers to the number of bits in a register, address bus, or data bus. For example, on a 64-bit motherboard, the data bus (silver wire between components) has 64 lines that are side-by-end. Memory addresses are addressed in memory in the form of bit
