In specific implementation, the startup video file can be acquired from the network through an operation means, and the video file can be prefabricated during the startup software package production. When the system is started, the boot video downloading program detects boot video information deployed at the cloud, if a boot video file needs to be downloaded or updated, the boot video file such as bootvideo. mp4 is downloaded to a certain appointed path of the local file system, and a boot video copy interface is called to copy the boot video file to the initialized video pts partition. When the equipment is started, uboot is started firstly, so that a starting video file stored in a starting video storage partition is read, the starting video file is analyzed and shunted, the analyzed and shunted video is output to a screen to be played, audio is output through an audio output interface, and the starting video is played.
In specific implementation, step S203 specifically includes:
s231, reading a startup video file stored in a startup video storage partition by a startup video program, and analyzing and shunting the startup video file into video and audio by a hardware decoder;
and S232, outputting the analyzed and shunted video to a screen for playing in a mode of fixing a graphic output protocol interface, and outputting audio through an audio output interface.
In specific implementation, the boot video program reads a video file bootvideo. mp4 stored in a video pts partition, and performs decode and stream distribution by using a hardware decoder. The analyzed and shunted video data is directly output to a screen for playing through a fixed GOP port (the phenomenon that the video data is initialized or reused when kernel or Android is started) and the audio data is output through an audio output interface. And starting the video to play. GOP is a short term for Graphic Output Protocol, and Chinese means graphics Output Protocol, which is used to extend graphics drivers to the interface of UEFI firmware, so as to replace the initialization behavior of conventional VBIOS (video BIOS) in terms of boot resource requirement.

step S50, decoding by Mpu hardware and branching by demux; after decoding and shunting, executing step S60, step S70 and step S80; wherein, the Mpu is a microprocessor of the system;
step S60, outputting the video code stream to a screen through a GOP port;
step S70, outputting the audio code stream to an audio output interface;
step S80, starting Android bootanimation;
step S90, setting bootanimation to be in a transparent state;
step S91, judging whether Android startup is completed, if so, executing step S92, and if not, executing step S50;
