Problems solved by technology

[0003] On the one hand, in order to obtain the time-domain layer information indicated in the coded stream, network devices need to decode the coded stream to obtain it. Considering the computational complexity of video decoding, it takes a lot of computing resources; on the other hand, in actual situations , many network devices do not support the implementation of the decoding algorithm, which will cause these network devices to be unable to obtain the time-domain level information in the encoded code stream

Abstract

The invention provides a file encapsulation method, a file transmission method, a file decoding method and related equipment. The file encapsulation method comprises the following steps: obtaining anencoded target video and time domain level information of a sample determined by the target video in an encoding process; encapsulating the encoded target video to generate a first encapsulation file,the first encapsulation file including time domain level information of the sample; and sending the first encapsulation file to a first device. According to the scheme provided by the embodiment of the invention, the corresponding time domain level information can be indicated in the file encapsulation.

Description

technical field [0001] The present disclosure relates to the technical field of video packaging, in particular, to a file packaging method, a file transmission method, a file decoding method, a file packaging device, a file transmission device, a file decoding device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In the video coding technology in the related art, although the time-domain hierarchical division technology is supported, only information such as the layer number of the image frame and the maximum number of layers are indicated in the coded code stream. [0003] On the one hand, in order to obtain the time-domain layer information indicated in the coded stream, network devices need to decode the coded stream to obtain it. Considering the computational complexity of video decoding, it takes a lot of computing resources; on the other hand, in actual situations , many network devices do not support the implementation of ...
