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 accompanying drawings in the embodiments of the present application.
[0030] In order to more clearly introduce the code stream error tolerance method provided by the embodiments of the present application, before introducing the code stream error tolerance method, the application scenarios and related technologies involved in the code stream error tolerance method are introduced.
[0031] The code stream error tolerance 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 HD and ultra-high-definition videos is quite large. Therefore, in the case of limited bandwidth, it is necessary to encode the video source to remove redundant information. The final binary file becomes ES (Elementary Stream, Elementary Stream). ) stream, the ES stream arri...

The present application provides a code stream error tolerance method and device, and a readable storage medium. The method includes: acquiring a code stream to be processed; the code stream to be processed includes header information of a target image frame; reading the header information in the code stream to be processed; If the header information is incomplete, store the previously stored header information or the preset header information in the code stream to be processed to obtain the processed code stream; if the wrong header information is read, use the previously stored header information The wrong header information is replaced with the original header information or the preset header information, and the processed code stream is obtained. This method can improve the stability of decoding.
Description
technical field [0001] The present application relates to the technical field of video decoding, and in particular, to a code stream error tolerance 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 influence of the encoding end on the error codes. Therefore, 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 consideration of universality and cost, the economic value of processing the code stream at the encoding transmitting 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. SUMMARY O...
