[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the drawings in the present invention. Obviously, the described embodiments are some, but not all, embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0033] The following will be combined with Figures 1-3 Describe the video processing method, device, electronic device and storage medium provided by the present invention.

[0034] Figure 1 The flowchart of a video processing method provided by the present invention is shown. Refer to Figure 1 , the method includes the following steps:

[0035] 11. Receive a playback request sent by a video recording device, where the playback request includes encoding format information and video data;

[0036] 12. Call a decoder corresponding to the encoding format information to decode the video data and play the decoded video data.

[0037] Regarding steps 11 to 12, it should be noted that in the present invention, this method is applicable to video monitoring of multiple warehouse environments. Due to different warehouse management, the video recording devices (i.e., cameras) purchased in the warehouse are different, which leads to different encoding formats of the video streams recorded by the cameras. If the monitoring videos of different warehouses are played on the platform, the platform needs to be able to decode video streams with different encoding formats to achieve playback.

[0038] In the present invention, multiple decoders are stored on the platform, and the decoding function of each decoder corresponds to a unique encoding format. Therefore, when a video recording device as the target needs to play a video, the video recording device will send a play request to the platform, and the play request includes encoding format information and video data. The encoding format information is the encoding format of the encoder in the video recording device. The video data is the picture data recorded by the video recording device for the warehouse environment. Correspondingly, the device identifier will also be marked in the video data.

[0039] After receiving the play request, the platform matches the encoding format information in the play request with the corresponding relationship between the pre-stored encoding format information and the decoder, determines the decoder corresponding to the encoding format information in the play request, calls the decoder to decode the video data, and then plays the decoded video data on the platform to achieve the monitoring of the warehouse environment.

[0040] The video processing method provided by the present invention matches the corresponding decoder through the encoding format information in the play request, and enables the matched decoder to decode the video data, so as to realize the playback of different video streams by the platform and achieve the purpose of monitoring each warehouse environment.

[0041] In a further method of the above method, when the platform plays the video data sent by the video recording device for the first time, the play request received by the platform includes encoding format information and video data, and the encoding format information is used to match a suitable decoder. However, the sending of these two types of information (encoding format information and video data) is likely to cause certain failure situations, such as a synthetic error resulting in an overall error in the play request, or separate sending being out of sync. Therefore, when the platform plays the video data sent by the video recording device for the first time, a corresponding relationship between the decoder and the device identifier of the video recording device can be established. The existence of this corresponding relationship enables the video recording device to apply for playing the video again without sending the encoding format information, but only needs to send the video data. Correspondingly, the platform will determine the device identifier from the video data, match the device identifier in the corresponding relationship to obtain the decoder corresponding to the device identifier, and then play the decoded video data on the platform to achieve the monitoring of the warehouse environment.

[0042] In a further method of the above method, after establishing the correspondence between the decoder and the device identifier, in order to enable the video recording device to only send video data subsequently, the platform needs to send a notification message to the video recording device corresponding to the device identifier based on the device identifier. After receiving the notification message, the video recording device will only send video data when requesting to play the video for the non-first time.

[0043] In a further method of the above method, after the decoder fails to decode the video data, it may be that the codec versions are not unified. For this reason, the platform needs to analyze the video data to determine the encoding version of the video data. After determining that the encoding version is lower than the decoding version of the decoder, a version upgrade file is sent to the video recording device so that the video recording device can upgrade its own encoding version.

[0044] In addition, when it is determined that the encoding version is the same as the decoding version, the platform will inform the video recording device that there may be a transmission error in the video data, so that the video recording device can resend the video data.

[0045] Next, the video processing device provided by the present invention will be described. The video processing device described below can be correspondingly referred to the video processing method described above.

[0047] The receiving module 21 is used to receive a play request sent by a video recording device. The play request includes encoding format information and video data.

[0048] The processing module 22 is used to call a decoder corresponding to the encoding format information to decode the video data and play the decoded video data.

[0049] In a further device of the above device, after playing the video data sent by the video recording device for the first time, the device further includes an establishing module for establishing the correspondence between the decoder and the device identifier of the video recording device.

[0050] Correspondingly, the processing module is further used to call a decoder corresponding to the device identifier to decode the video data and play the decoded video data.

[0051] In a further device of the above device, after establishing the correspondence between the decoder and the device identifier, the device further includes a notification module for:

[0052] Sending a notification message to the video recording device corresponding to the device identifier based on the device identifier, so that the video recording device only sends video data when requesting to play the video for the non-first time.
