A data processing method for immersive media, applicable to a computer device, the method comprising: obtaining a media file format data box of immersive media, the media file format data box comprising a zoom policy of the i th zoom region of the immersive media in a target zoom mode, i being a positive integer, wherein the target zoom mode refers to performing zoom processing on the i th zoom region according to the zoom policy when the i th zoom region in the immersive media satisfies a zoom condition, the zoom policy is generated according to zoom information specified by an immersive media content producer and the zoom policy corresponding to the zoom information carries position information of the i th zoom region, the zoom condition, size information and a zoom ratio, and the zoom processing comprises m zoom steps, the zoom policy of the media file format data box is further extended to include m zoom ratio fields, m being a positive integer; wherein the j th zoom step in the m zoom steps corresponds to the j th zoom ratio field in the m zoom ratio fields, j being a positive integer, and j being less than or equal to m; the j th zoom ratio field is used for indicating a zoom ratio adopted when the j th zoom step in the zoom processing is performed on the i th zoom region of the immersive media; when a value of the j th zoom ratio field is an ineffective value, the j th zoom ratio field is used for indicating that a size of the i th zoom region of the immersive media after the j th zoom step of the zoom processing is performed in the target zoom mode thereon is the same as a size thereof before the zoom processing is performed thereon; and when the value of the j th zoom ratio field is an effective value, the j th zoom ratio field is used for indicating that a ratio between the size of the i th zoom region of the immersive media after the j th zoom step of the zoom processing is performed in the target zoom mode thereon and the size thereof before the zoom processing is performed thereon is the value of the j th zoom ratio field; obtaining a zoom description signaling file of the immersive media, the zoom description signaling file comprising description information of the zoom policy; and performing zoom processing on the i th zoom region of the immersive media according to the media file format data box, wherein the performing zoom processing on the i th zoom region of the immersive media in an encapsulated file according to the media file format data box comprises: performing zoom processing on the i th zoom region of the immersive media in the encapsulated file according to the zoom policy comprised in the media file format data box and the description information of the zoom policy comprised in the zoom description signaling file. obtaining a media file format data box of immersive media, the media file format data box comprising a zoom policy of the i th zoom region of the immersive media in a target zoom mode, i being a positive integer, wherein the target zoom mode refers to performing zoom processing on the i th zoom region according to the zoom policy when the i th zoom region in the immersive media satisfies a zoom condition, the zoom policy is generated according to zoom information specified by an immersive media content producer and the zoom policy corresponding to the zoom information carries position information of the i th zoom region, the zoom condition, size information and a zoom ratio, and the zoom processing comprises m zoom steps, the zoom policy of the media file format data box is further extended to include m zoom ratio fields, m being a positive integer; wherein the j th zoom step in the m zoom steps corresponds to the j th zoom ratio field in the m zoom ratio fields, j being a positive integer, and j being less than or equal to m; the j th zoom ratio field is used for indicating a zoom ratio adopted when the j th zoom step in the zoom processing is performed on the i th zoom region of the immersive media; when a value of the j th zoom ratio field is an ineffective value, the j th zoom ratio field is used for indicating that a size of the i th zoom region of the immersive media after the j th zoom step of the zoom processing is performed in the target zoom mode thereon is the same as a size thereof before the zoom processing is performed thereon; and when the value of the j th zoom ratio field is an effective value, the j th zoom ratio field is used for indicating that a ratio between the size of the i th zoom region of the immersive media after the j th zoom step of the zoom processing is performed in the target zoom mode thereon and the size thereof before the zoom processing is performed thereon is the value of the j th zoom ratio field; obtaining a zoom description signaling file of the immersive media, the zoom description signaling file comprising description information of the zoom policy; and performing zoom processing on the i th zoom region of the immersive media according to the media file format data box, wherein the performing zoom processing on the i th zoom region of the immersive media in an encapsulated file according to the media file format data box comprises: performing zoom processing on the i th zoom region of the immersive media in the encapsulated file according to the zoom policy comprised in the media file format data box and the description information of the zoom policy comprised in the zoom description signaling file.
