In another scenario, in order to verify whether the format switching process is successful and ensure the reliability of the format switching process, on the basis of fig. 3, as shown in fig. 4, the method may further include the following steps:

Optionally, the preset duration may be any value as long as the duration of one format switching process can be satisfied, that is, the preset duration may be greater than or equal to the duration of one format switching process. Optionally, the current switching information query instruction may be used to query current switching information of the video signal obtained after the format switching processing by the test end 106. Optionally, after the tested terminal 106 responds to the current switching information query instruction, the current switching information of the video signal obtained after the format switching processing may be fed back to the control terminal 104. Optionally, the video signal obtained after the format switching process may be a target video signal or may not be the target video signal.
The current handover information and the target handover information may correspond to each other. If the target switching information is the target resolution, the current switching information can be the current resolution; the target switching information is the target video volume size, the current switching information may be the current video volume size, and so on.
And S230, matching the current switching information with the target switching information, and determining a matching result, wherein the matching result is used for indicating whether the format switching of the initial video signal is successful.
Specifically, the control end 104 may match the obtained current handover information with the target handover information to determine a matching result. The matching process may be understood as comparing whether the two switching information are consistent.
The step of matching the current handover information with the target handover information in S230 to obtain a matching result may specifically include: if the current switching information is the same as the target switching information, the matching result indicates that the format switching is successful; and if the current switching information is different from the target switching information, the matching result indicates that the format switching fails.
In this embodiment, if the control end 104 determines that the current switching information is consistent with the target switching information, it may represent that the format switching of the initial video signal is successful, and at this time, the tested end 106 may determine the video signal obtained after the format switching as the target video signal; if the control end 104 determines that the current switching information is inconsistent with the target switching information, it may characterize that the format switching of the initial video signal fails, and at this time, the video signal obtained after the format switching by the tested end 106 cannot be determined as the target video signal.
In addition, in some scenarios, in order to output a video signal obtained after format switching on the basis of ensuring that format switching is successful, the video processing method may further include: and if the matching result indicates that the format switching is successful, sending a video output instruction to the tested end, wherein the video output instruction is used for indicating the tested end to output the target video signal.
It can be understood that, when the matching result obtained by the control end 104 indicates that the format switching is successful, at this time, the control end 104 may send a video output instruction to the tested end 106 to instruct the tested end 106 to output the target video signal. Optionally, the target video signal may be a video signal obtained after format switching.
In the video processing method, the controlled terminal can send a current switching information query instruction to the tested terminal when a preset time length after sending the video format switching instruction is reached, receive current switching information corresponding to the video signal obtained after the tested terminal feeds back format switching according to the current switching information query instruction, match the current switching information with the target switching information to determine a matching result, and further indicate whether the target video signal can be output currently according to the matching result; the method can realize a set of automatic video format switching processing process to meet the requirements of users on video format switching, reduces manual processing process, shortens the period of video format switching, saves labor cost and further improves the switching speed of video format switching.
In one scenario, in order to implement an automatic processing video format switching process, a video format switching instruction carrying target switching information needs to be automatically generated first, so as shown in fig. 5, the step of sequentially generating video format switching instructions according to different target switching information in S200 according to a target switching time interval may specifically include the following steps:
s201, sequentially acquiring each target switching information from a target switching information list according to the target switching time interval and the target switching cycle number, wherein the target switching information list comprises a plurality of switching resolutions.
Specifically, the control end 104 may sequentially obtain each target handover information from the target handover information list according to the target handover time interval and the target handover cycle number. If the target switching information is the target resolution, the target switching information list may include a plurality of target resolutions, target switching time intervals, and target switching cycle numbers.
Wherein, the following table 1 is an example of a target switching information list, where in table 1, there are 3 target resolution data, a first target resolution is 320 × 180ppi, and a corresponding target switching time interval is 4s, that is, the control terminal 104 instructs the controlled terminal 102 to switch the initial resolution of the initial video signal to 320 × 180ppi, and executes the next resolution switching process after waiting for 4s, that is, the control terminal 104 instructs the controlled terminal 102 to switch the initial resolution of the initial video signal to 350 × 200ppi (i.e., a second target resolution), and then continues to wait for 5s and execute the next resolution switching process, that is, the control terminal 104 instructs the controlled terminal 102 to switch the initial resolution of the initial video signal to 400 × 260ppi (i.e., a third target resolution); the above resolution switching processing is performed 3 times in total (i.e., the target switching cycle number), and the target switching time interval corresponding to the third target resolution in table 1 is empty, which represents the target resolution corresponding to the last resolution switching processing.
