Problems solved by technology

[0002] At present, the playback of panoramic video based on the Android platform adopts a soft decoding method, that is, the decoding algorithm is directly called to allow the central processing unit (Central Processing Unit, CPU) to decode the panoramic video. Such decoding efficiency is low, and it increases the burden on the CPU and consumes Electricity also increases a lot
