Problems solved by technology
[0002] In the process of video decoding, code errors are prone to occur. Most of the existing technologies focus on how to eliminate the impact of code errors on the encoding end. Therefore, corresponding measures are designed in the encoder to prevent errors.
[0003] However, for practical application scenarios, the error probability of the encoder is very small, and for the sake of universality and cost considerations, the economic value of processing the code stream at the encoding sending end is low and the receiving end cannot be guaranteed to be completely error-free
[0004] Therefore, the fault tolerance mode of the prior art is not simple and practical enough, so that the stability of video decoding is not high

Embodiment Construction
[0029] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0030] In order to more clearly introduce the code stream fault-tolerant method provided by the embodiment of the present application, before introducing the code stream fault-tolerant method, the application scenarios and related technologies involved in the code stream fault-tolerant method are introduced first.
[0031] The code stream error-tolerant method is applied to video decoding, and specifically can be applied to various video decoders.
[0032] Regarding video decoding, the amount of source data of popular high-definition and ultra-high-definition videos is quite huge. Therefore, in the case of limited bandwidth, it is necessary to encode the video source to remove redundant information. The final binary file becomes an ES (Elementary Stream, elementary stream) ) stream, the ES stream ar...

The invention provides a code stream fault tolerance method and device and a readable storage medium. The method comprises the following steps: acquiring a to-be-processed code stream, wherein the to-be-processed code stream comprises header information of a target image frame; reading the header information in the to-be-processed code stream; if the header information in the to-be-processed codestream is incomplete, storing the header information stored in advance or preset header information in the to-be-processed code stream to obtain a processed code stream; if the wrong header information is read, replacing the wrong header information with pre-stored header information or preset header information to obtain a processed code stream. The method can improve the decoding stability.
Description
technical field [0001] The present application relates to the technical field of video decoding, in particular, to a code stream error-tolerant method and device, and a readable storage medium. Background technique [0002] In the process of video decoding, code errors are prone to occur. Most of the existing technologies focus on how to eliminate the impact of code errors on the encoding end, so corresponding measures are designed in the encoder to prevent errors from occurring. [0003] However, for practical application scenarios, the error probability of the encoder is very small, and for the sake of universality and cost, the economic value of processing the code stream at the encoding sending end is low and the receiving end cannot be guaranteed to be completely error-free. [0004] Therefore, the fault-tolerant method in the prior art is not simple and practical enough, so that the stability of video decoding is not high. Contents of the invention [0005] The purp...
