In this way, by performing the divisional segmented detection on the target video stream data according to the detection time interval obtained by division, not only can the efficiency and reliability of the security detection be improved, but also the terminal device can be ensured to receive at least part of the video stream data passing the security detection in time. Therefore, the safety detection of the video stream data issued by the live broadcasting platform side can be realized, and meanwhile, the fluency of the terminal equipment side in the live video playing process is ensured.
In practical application, the inventor finds that the problem of confusion of the types of the thread parameters often occurs when the current thread parameters are extracted. The reason is that the thread identifiers between the multiple processing threads of the terminal device are not distinguished, and the transfer matching between the thread parameters and the thread identifiers is not considered. To improve this technical problem, the extracting, from the device running log of the terminal device, the current thread parameter of the video output thread corresponding to the terminal device described in step S21 may specifically include what is described in the following step S211 to step S214.

Step S213, selecting a target thread identifier whose identifier update frequency does not change with the change of the time slice resource occupancy rate of the terminal device from the first identifier cluster set, determining a target processing thread corresponding to the target thread identifier according to a preset mapping list, and determining the target processing thread as the video output thread.
Step S214, extracting multiple sets of thread parameters corresponding to the video output threads from the device running log, calculating a transfer matching rate between the parameter directing weight corresponding to each set of thread parameters and the identifier directing weight of the target thread identifier, and determining the thread parameter corresponding to the maximum transfer matching rate as the current thread parameter.
It can be understood that when the contents described in steps S211 to S214 are applied, the thread identifiers between multiple processing threads of the terminal device can be distinguished, and the delivery matching between the thread parameter and the thread identifier is considered, so that the category of the current thread parameter can be prevented from being confused, and the accuracy of the current thread parameter can be ensured.
In the process of the foregoing embodiment, the inventor further finds that there is a technical problem that the pre-delay duration value is too large when determining the pre-delay duration value, which may cause a long delay or pause when playing a live video, and to improve this technical problem, in step S22, the pre-delay duration value of the terminal device when playing a video is determined by using the current thread parameter, and further may include the contents described in the following steps S221 to S223.
Step S221, determining path delay information corresponding to a parameter execution path of the current thread parameter and a path stability index of the parameter execution path; the path stability index represents the running stability of a parameter execution path of the current thread parameter; the path stability indicator includes at least: and the first stability coefficient and the second stability coefficient represent the running stability of the parameter execution path of the current thread parameter.
Step S222, generating a delay curve corresponding to the path delay information; the delay curve comprises a pre-configured curve node label, and the curve node label represents delay adjustment information of a parameter execution path which is positioned on the delay curve and corresponds to the path delay information.
Step S223, obtaining operation node data of the terminal device during video playing according to each curve node label in the delay curve, and obtaining target node data by extracting node connection information in the operation node data to realize error correction of the operation node data; and extracting numerical value information in each group of target node data and weighting the target numerical values in the numerical value information according to the node connection information to obtain a pre-delay time length value.
In specific implementation, when the contents described in the above steps S221 to S223 are applied, the pre-delay duration value can be accurately calculated, and the pre-delay duration value obtained through calculation is prevented from being too large, so that it is ensured that the terminal device does not have a long delay or pause when playing the live video.
On the basis, the step S223 may further include the following steps S2231 to S2234, which are described below, of extracting the numerical information in each set of target node data and weighting the target numerical value in the numerical information according to the node connection information to obtain the pre-delay duration value.
Step S2231, counting the dynamic data corresponding to each group of target node data, generating a dynamic graph data form corresponding to the dynamic data, and generating a data structure form corresponding to data structure difference information between different target node data; the dynamic graph data form and the data structure form respectively comprise a plurality of form elements with different information dimensions, and the form elements are used for recording corresponding form information.
Step S2232, obtaining a form information code of a form element with the highest calling frequency of the dynamic data in the dynamic graph data form, and determining the form element with the smallest information dimension in the data structure form as a reference form element when a decoder state corresponding to the form information code is an idle state.
Step S2233, loading the form information code into a code field corresponding to the reference form element based on the curve characteristic of the delay curve to obtain a transform code corresponding to the form information code in the code field corresponding to the reference form element; and generating an associated logic list between the dynamic data and the data structure difference information according to a bit-by-bit comparison result between the form information code and the conversion code.
Step S2234, extracting numerical value information in each group of target node data according to the association logic list and determining a numerical value distribution queue corresponding to the numerical value information; and extracting the value distribution queue according to the node connection information to obtain at least one target value in the value distribution queue, and weighting the target value by adopting a vector characteristic value corresponding to the node connection information to obtain a pre-delay time value.
