The media software development kit from HiSilicon (Shanghai) can adapt to complex underlying layers of different chips. It also provides basic multimedia processing functions for the multimedia subsystem, including audio/video collection, audio/video encoding and decoding, audio/video output, video pre-processing, encapsulation, decapsulation, file management, storage management, and log system. The multimedia subsystem architecture is shown as Figure 1
