The hardware information of the so-called video encoding hardware refers to the basic attributes of the hardware name, hardware type, and data format of the image data to be processed of the video encoding hardware. According to the hardware information of the video encoding hardware, the data format of the image data to be processed required by the video encoding hardware when performing the video encoding process may be determined, and the data format may be used as the specified data format.

In a specific implementation process, the projected image data may be directly stored. To specify the data format, for example, RGB_565, where R represents the red component, the G green component, and the B blue component, and the RGB values are recorded with 5 bits, 6 bits, and 5 bits, respectively, ie, R=5, G=6, B= 5, then, a pixel points account for 5 + 6 + 5 = 16 bits.

For example, since the storage format of the image data of the interface displayed by the display device of the different terminal device is different, the image data of any interface displayed by the display device of the second terminal device may be acquired in advance, according to the image data. Determine its storage format. If the storage format is the specified data format, the subsequently obtained projection image data may be directly stored; if the storage format is not the specified data format, then the subsequent obtained The projected image data of the storage format is first converted into projected image data of the specified data format, and then stored. For the specific conversion rule, the conversion rule provided in the prior art may be used, or the conversion rule customized by the present invention may also be used, which is not specifically limited in this embodiment.

The ARGB value is recorded with 8 bits, that is, A=8, R=8, G=8, and B=8, then one pixel point occupies 8+8+8+8=32 bits.

For example, since the storage format of the image data of the interface displayed by the display device of the different terminal device is different, the image data of any interface displayed by the display device of the second terminal device may be acquired in advance, according to the image data. Determine its storage format. If the storage format is the preset data format, the subsequently obtained projected image data may be directly stored; if the storage format is not the preset data format, then the subsequent The obtained projected image data of the storage format is first converted into projected image data of the preset data format, and then stored. Among them, the specific conversion rules, The conversion rules provided in the prior art may be used, or the conversion rules customized by the present invention may also be used, which is not specifically limited in this embodiment.
