Aiming at the problem of virtual reality and data processing algorithm of online video packaging, one transmission scheme uses TILES in HEVC to block the video and then applies MP4Box to pack the video and generate a DASH video stream. A method is proposed to process the same panoramic video with different quality. By designing a new index to measure the complexity of the coding tree unit, this method predicts the depth of the coding tree unit by using the complexity index and spatial correlation of the video, skipping unnecessary traversal range, and realizing fast division of coding units. Experimental results show that compared with the latest HM16.20 reference model, the proposed algorithm can reduce the coding time by 37.25%, the BD-rate only increases by 0.74%, and the video image quality is almost not lost.
