The specific steps of logging in the target video platform are as follows:
first, a first login is performed, that is, a login request sent by a user through a front-end device is received, and the login request is sent to a target video platform based on the login request. After receiving the login request, the target video platform returns a secret key, service domain information and an encryption type if the login request is legal, namely, the user sending the login request is a legal user.
Then, the key, the service domain information and the encryption type returned by the target video platform are received. The encryption type here refers to the encryption type of the key, and may specifically be an MD5 encryption type or an SA encryption type.

And finally, pulling a plurality of video streams from the video stream address, and storing the pulled video streams, wherein each video stream is transcoded based on the characteristics of front-end equipment in the storage process so as to adapt to subsequent playing.
S3, receiving input event information according to a query request of a user.
The event information refers to related information of the current time, such as the place, time and vehicle information of the accident, etc., when the user needs to inquire and play back the video, the user can input a corresponding inquiry request through the front-end equipment, and input the event information while sending the inquiry request.
And S4, sending one or more video streams to the user.
The video stream corresponding to the event information input by the user is sent to the user, specifically to the front-end equipment for the user to input the query request, so that the user plays the video stream through the front-end equipment. The video stream may be one or a plurality of video streams.

Through the scheme, the user can acquire the corresponding video at any time based on the corresponding front-end equipment, namely, the direct playing of the real-time bare data stream is realized, and accordingly, the accident scene can be processed in time.
In addition, in a specific implementation manner of this embodiment, the method further includes the following steps, as shown in fig. 2:
s5, realizing direct control of the ball machine according to the ball machine control request of the user.
When the ball machine control request sent by the user is received, a corresponding ball machine control instruction is sent to the target video platform based on the token, and the ball machine control instruction is used for controlling the steering of the controlled ball machine connected with the target video platform, so that the controlled ball machine obtains the current video required by the user. The method is realized by the following steps:
first, after receiving a user's dome camera control request, the device number of the target dome camera and the target video channel number corresponding to the device number are acquired from the database.
And then, the token and the rotation coefficient are sent to the target video platform, so that the target video platform controls the controlled ball machine to rotate according to the rotation coefficient so as to control the controlled ball machine to turn to the target direction required by a user, and the characteristics of focal length, aperture and the like of the controlled ball machine are controlled in the rotation process, before rotation or after rotation is completed.
Through the step, the user can acquire the current video, and the real-time tracking and evidence obtaining of pedestrians and vehicles are realized.

Such a propagated data signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination of the foregoing. A computer readable signal medium may also be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to: electrical wires, fiber optic cables, RF (radio frequency), and the like, or any suitable combination of the foregoing.
In this specification, each embodiment is described in a progressive manner, and each embodiment is mainly described by differences from other embodiments, and identical and similar parts between the embodiments are all enough to be referred to each other.
While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiment and all such alterations and modifications as fall within the scope of the embodiments of the invention.
Finally, it is further noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or terminal that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or terminal. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article or terminal device comprising the element.
The foregoing has outlined rather broadly the more detailed description of the invention in order that the detailed description of the invention that follows may be better understood, and in order that the present principles and embodiments may be better understood; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present invention, the present description should not be construed as limiting the present invention in view of the above.
