Embodiment 1
[0060] Such as figure 2 As shown, the decoding process of the panoramic video, the mapping of the decoded video data to N viewing angles, and the encoding of the N channels of video data obtained after mapping are all performed by the GPU, and the encoded video streams are sliced and packaged. Processing is performed by the CPU.
Embodiment 2
[0062] Such as image 3 As shown, the decoding process of the panoramic video is performed by the CPU, the mapping of the decoded video data to N viewing angles, and the encoding of the N channels of video data obtained after mapping are all performed by the GPU, and the encoded video streams of each channel are The slicing and packing process is performed by the CPU.
Embodiment 3
[0064] Such as Figure 4 As shown, the decoding process of the panoramic video is performed by the GPU; the video data obtained by decoding is mapped to M viewing angles by the GPU, and the remaining N-M viewing angles are mapped to the remaining N-M viewing angles to be executed by the CPU; among the N road video data obtained after mapping The encoding processing of the P channels is performed by the GPU, and the encoding processing of the remaining N-P channels is performed by the CPU; the slicing and packaging of the encoded video streams are performed by the CPU.
