Abstract
Panoramic video transcoding methods, devices, and apparatuses are provided. The method involves a central processing unit (CPU) and a graphics processing unit (GPU) and includes decoding a panoramic video; mapping, at least partly using the GPU, the decoded video data to N visual angles, to obtain N channels of video data, in which N is more than 1; encoding the N channels of video data respectively to obtain N channels of video streams; and slicing and packing the N channels of video streams respectively.
