Abstract
The present subject matter provides a media file packing and unpacking method, apparatus and device, and a storage medium. Code streams after N items are coded. The items comprise point clouds or static panoramic images. N is a positive integer greater than 1. The code streams of the N items are packed into at least one entity group. A first indication information is added to the entity group with regard to each entity group in at least one entity group to obtain media files of the N items. The first indication information indicates the types of all items having an association relation in the entity group. The media files of the N items are transmitted to the file unpacking device.
Claims20
A media file packing method applied to a file packing device, comprising:
- acquiring code streams after N items are coded, wherein
- the items comprise point clouds or static panoramic images, and
- N is a positive integer greater than 1;
- packing the code streams of the N items in at least one entity group;
- adding, with regard to each entity group in the at least one entity group, first indication information to the entity group to obtain media files of the N items, wherein
- the first indication information is used for indicating media types of all items having an association relation in the entity group and the first indication information is configured to enable a file unpacking device to determine a target item to be decoded in the entity group;
- and
- transmitting the media files of the N items to the file unpacking device.
A media file unpacking method, applied to a file unpacking device, comprising:
- receiving media files of N items transmitted by a file packing device, wherein the items comprise at least one of point clouds or static panoramic images, N is a positive integer greater than 1, the media files comprise an entity group, a code stream of at least one item is packed into the entity group, the media files further comprise first indication information corresponding to each entity group, and the first indication information is used for indicating media types of all items having an association relation in the entity group;
- determining, with regard to each entity group in the at least one entity group, a target item to be decoded in the entity group according to the first indication information corresponding to the entity group;
- unpacking the target item to obtain the code stream of the target item;
- and
- decoding the code stream of the target item to obtain the target item.
A media file unpacking device, comprising:
- a processor;
- and
- a memory coupled to the processor and storing a computer program executable by the processor to configure the processor to:
- receive media files of N items transmitted by a file packing device, wherein the N items comprise at least one of point clouds or static panoramic images, N is a positive integer greater than 1, the media files comprise an entity group, a code stream of at least one item is packed into the entity group, the media files further comprise first indication information corresponding to each entity group, and-the first indication information is used for indicating media types of all items having an association relation in the entity group;
- determine, with regard to each entity group in the at least one entity group, a target item to be decoded in the entity group according to the first indication information corresponding to the entity group;
- unpack the target item to obtain the code stream of the target item;
- and
- decode the code stream of the target item to obtain the target item.
