Example Embodiment

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to embodiments and drawings.

[0028] Existing methods for analyzing video code streams require analysts to parse and identify captured files manually, which has low efficiency and large workload. In order to solve this technical problem, the present invention obtains the packet capture file from the network card, and automatically restores the real-time video code stream based on the packet capture file. Based on the restored video code stream, it can be determined whether the data via the corresponding network card is normal. As a result, the efficiency of video stream analysis is improved, and human workload is greatly reduced.

[0029] See figure 1 , Is a schematic flowchart of a method for restoring a real-time video code stream of the present invention, which includes the following steps:

Abstract

The invention discloses a method and device for reproducing a real-time video code stream. The method comprises that data of a network interface card is grabbed, a grabbing packet file is obtained; a data packet is read from the grabbing packet file, a time stamp is obtained from the head of the data packet, and the length of code stream data in the content of the data packet is determined; code stream data is extracted from the content of the data packet according to the determined length; and the code stream data is sent to a player for play according to the time stamp. The method and device can be used to improve the analysis efficiency of the video code stream.

Description

technical field [0001] The invention relates to a video code stream processing technology, in particular to a method and device for restoring a real-time video code stream. Background technique [0002] After the data acquisition end collects data, it transmits to the client through the intermediate network. After the client receives the data, it plays to view the scene status of the collection end. Under normal circumstances, the video code stream played by the client is clear and smooth, which can accurately monitor the status of the camera scene. However, in some cases, the video code stream played by the client is abnormal, and there are phenomena such as frame skipping, freezing, blurring, etc., which cannot achieve the purpose of monitoring; in this case, it is necessary to analyze the video code stream to determine the occurrence of the fault location for maintenance. [0003] Existing solutions for analyzing video code streams include: whether it is the client or ...
