Embodiment Construction

[0020] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all implementations. Exhaustive list of examples. And in the case of no conflict, the embodiments in this description and the features in the embodiments can be combined with each other.

[0021] The inventor noticed during the course of the invention that:

[0022] Due to the fact that the capture of abnormal flow or abnormal phenomenon of small probability events in the existing technology needs to occupy a large host storage space, and there are certain limitations in reproducing abnormal phenomena offline, that is, it is impossible to guarantee the consistency and consistency of abnormal phenomena. The root cause of the anomaly cannot be loc...

Abstract

The invention provides a method and device for processing abnormal data, belonging to the technical field of network video stream processing. The method includes: by performing offline decoding monitoring on the segmented video stream of the session, judging whether there is a decoding abnormality in the current segmented video stream; if there is a decoding abnormality in the current segmented video stream, obtaining the online Containing abnormal context information of the location of the abnormal decoding phenomenon in the current segmented video stream; reproducing the abnormal video stream in the current segmented video stream on the line according to the obtained abnormal context information. By adopting the technical scheme of the invention, the accuracy of reappearance and analysis of abnormal data can be improved, thereby realizing the improvement of the fault tolerance of the video processing system itself.

Description

technical field [0001] The invention relates to the technical field of network video stream processing, in particular to a method and device for processing abnormal data based on segmented video streams. Background technique [0002] With the rapid development of the Internet, the video transmission traffic based on the network is also increasing. In the actual application of the field of network video stream processing, due to the characteristics of segmented download and UDP protocol, packet loss and data mutation during data transmission, disordered and incomplete video streams exist. When dealing with these segmented abnormal video streams, such as decoding, the common method is to directly discard the abnormal streams that cannot be decoded normally. This abnormal stream refers to the video stream that cannot be decoded normally by the video decoding system, including Decoding pseudo-abnormal streams that cannot be decoded by the system itself. [0003] When dealing w...
