Problems solved by technology

[0003] With the development of chip technology, in traditional technology, mainstream cameras support independent encoding of H264 and H265 video encoding types, and are open to users for free configuration. Users can freely change the video encoding type of cameras through management platform software or private configuration channels. ;After the video encoding format of the camera changes, the video recording format stored in the SD card will also change, which will cause the SD card to store mixed data in multiple video formats; the decoding of different video formats corresponds to different decoding In this way, using the H264 decoding library to parse the H265 video data will result in decoding failure, and the video cannot be decoded and displayed normally; if the user requests to play the time period that contains data in multiple video formats, only the first video data can be played normally , when encountering data in different video formats, the decoding will be abnormal, resulting in failure of the subsequent playback process

Embodiment Construction

[0067] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0068] The video data playback processing method provided by the embodiment of the present invention can be applied to such as figure 1 The front camera is shown in the playback system. The front-end camera playback system includes: a video acquisition module, an SD card storage module, a transmission module, a data receiving module, a playback management module and a decoding display module. This method mainly solves the problem of abnormal decoding caused by mixed encoding type data in the video. Front-end camera playback system such as figure 1 As shown, the method p...

Abstract

The invention relates to a video data playback processing method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a video data playback processing request, the video data playback processing request comprising playback time information; Sending an RTSP playback request to receive the returned decoding information according to the playback time information, and initializing a decoder according to the returned decoding information; Sending an RTSP playing request to receive the returned RTP data stream, and analyzing an expansion field in the RTPdata stream to obtain an analysis result of the expansion field; Judging whether the coding mode of the RTP data stream is changed or not according to the analysis result of the extended field; And if the coding mode of the RTP data stream is changed, taking time information in the analysis result of the extended field as new request playing time to initiate a new RTSP playback request. Accordingto the method, the problem of data playback of mixing of various video formats is solved, so that the coherence of the whole playback process is ensured, and the use convenience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of video data processing, in particular to a video data playback processing method, device, computer equipment and storage medium. Background technique [0002] At present, video surveillance is an important technical means of modern city management. Video surveillance cameras are key equipment in video surveillance applications. Surveillance cameras generally have SD card storage functions for local storage of front-end video data. In a complete monitoring application system, the camera will be connected to a dedicated storage server to store high-definition video data. The significance of SD card local storage is that when the storage server fails, the power is cut off, the transmission channel network is abnormal, etc., it will serve as Backup channel for video data storage; or in some small application systems, due to cost considerations, there is no dedicated storage server, and the SD card loca...
