[0050] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below with reference to the accompanying drawings.

[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0052] For ease of understanding, a video quality detection method, apparatus, device and medium provided in an embodiment of the present application are described in detail below with reference to the accompanying drawings.

[0053] refer to Figure 1 As shown, it is a flow chart of a video quality detection method provided in an embodiment of the present application. The method can be applied to terminal devices, and the terminal devices are not limited to mobile phones, computers, etc. The method may include the following steps.

[0054] S101, based on a triggering operation on a video acquisition task, obtaining a first script file corresponding to the video acquisition task.

[0055] A video capture card is installed on the terminal device, and the video capture card has the function of video capture. Specifically, the video capture card can be inserted into the corresponding interface of the terminal device, for example, it can be inserted into the memory stick interface. The type of the video capture card is not specifically limited, for example, it can be a high-definition multimedia interface (HDMI) video capture card. In addition, the relevant driver of the video capture card can be installed on the terminal device so that the video capture card can work normally. The screen display software attached to the video capture card can also be installed on the terminal device to watch the captured video.

[0056] The video capture card can also be connected to the TV box, and the two can be connected via a data cable. When the video capture card is an HDMI video capture card, the HDMI video capture card has an HDMI interface and can be connected to the TV box via an HDMI data cable.

[0057] The TV box can be used to play videos. When the TV box is connected to a monitor, the TV box can output a video stream to the monitor so that the monitor can display the picture. Video software is installed on the TV box. The video software is a program for playing videos. When the video software is installed on the TV box, the video software can be opened to play the video. Among them, one or more video software can be installed on a TV box.

[0058] The video acquisition task can be understood as a task that requires video acquisition. Based on a triggering operation on the video acquisition task, the terminal device can obtain a first script file corresponding to the video acquisition task.

[0059] The triggering operation of the video acquisition task can be a click operation on the video acquisition task control. By clicking the control, the task is triggered. In actual applications, the task can be triggered in the task management webpage. The task management webpage has a video acquisition task control. When the user clicks the control, it means that the video acquisition task is triggered. Of course, it can also be timed, that is, when the preset time is reached, the video acquisition task is automatically triggered. The webpage can be deployed on the terminal device or on another terminal device.

[0060] When the task management webpage is deployed on the terminal device, the terminal device can receive a trigger operation of the video acquisition task by the user, and based on the trigger operation, the first script file stored locally can be retrieved, that is, the first script file can be obtained. The correspondence between the video acquisition task and the first script file can be stored on the terminal device, so that the first script file can be found based on the correspondence.

[0061] When the task management webpage is deployed on another terminal device, the corresponding relationship between the video acquisition task and the first script file is also stored on the terminal device. When the terminal device receives the user's trigger operation on the video acquisition task, the corresponding first script file can be found based on the trigger operation and sent to the terminal device with the video acquisition card installed, so that the terminal device with the video acquisition card installed can obtain the first script file. In addition, when constructing the task management webpage, you can use springboot, tomcat, mysql and other technologies to implement it.

[0062] The first script file can be understood as a pre-designed script file that can realize video acquisition. As an example, the first script file can be a python executable script file. The first script file includes a first identifier of the target TV box. The target TV box can be understood as a specified TV box connected to the video capture card. The identifier of the target TV box can be recorded as the first identifier. The first identifier is used to identify the target TV box from multiple TV boxes. As an example, the first identifier can be the name, number, etc. of the target TV box.

[0063] S102: Generate a first control instruction through a first script file.

[0064] Specifically, the terminal device can run the first script file. During the running process, the first control instruction can be generated through the first script file, and the first control instruction is used to control the target TV box to perform a corresponding operation.

[0065] S103: Send a first control instruction to the target TV box based on the first identifier.

[0066] The terminal device is also directly connected to the TV box, for example, via a wired or wireless connection, so that the terminal device can communicate directly with the TV box and send control instructions directly to the TV box.

[0067] The terminal device can determine the target TV box according to the first identifier, and send the first control instruction to the target TV box based on the first identifier, wherein the first control instruction includes the second identifier of the target video software. The target video software can be a certain video software configured on the target TV box, and the identifier of the target video software can be recorded as the second identifier. The second identifier can uniquely identify the target video software. As an example, the second identifier can be the name of the target video software, etc.

[0068] The first control instruction is used to instruct the target TV box to play the video through the target video software. That is, the target TV box is directly connected to the terminal device, and when the target TV box receives the first control instruction including the second identifier sent by the terminal device, under the control of the first control instruction, the target video software corresponding to the second identifier can be determined according to the second identifier, and the target video software can be controlled to start playing the video.

[0069] In actual applications, the terminal device and the target TV box can communicate through an automation tool. An automation tool, such as the Airtest tool, is installed on the terminal device. The first script file can be run in the automation tool. During the operation, a first control instruction can be generated and sent to the target TV box through the automation tool, thereby controlling the target TV box to automatically play the video. For example, the target TV box can be controlled to automatically log in to an account, automatically select a video, fast forward, fast rewind, etc.

[0070] S104, obtaining the video stream of the video output by the target TV box through a video capture card.

[0071] Under the control of the first control instruction, the target TV box can open the target video software to play the video, and at this time, the target TV box can output the video stream of the video. In the related art, the target TV box can be connected to a display to send the video stream to the display so that the display can display the picture.

[0072] In the present application, the target TV box is no longer connected to the display, but is directly connected to the video capture card, so that the video capture card can capture the video stream output by the target TV box.

[0073] In a possible implementation, the first control instruction may also include a preset duration for the video, which may not be greater than the total duration of the video, for example, 5 minutes. The first control instruction may also be used to indicate the duration of the target TV box to play the video through the target video software, reaching the preset duration. In short, when the duration of the target video software playing the video meets the preset duration, the target TV box may be controlled to stop playing, and the video stream captured by the video capture card is the video stream of the video clip corresponding to the preset duration. For example, the video stream is a video stream of a 5-minute video clip. In addition, after the playback is completed, the target TV box may be restored and the target TV box may be turned off.

[0074] S105: Generate a video file based on the video stream.

[0075] The video capture card can convert the captured video stream into a video file, which can be in MP4 format, so that the terminal device can obtain the video file. The video file is used to detect the playback quality of the target video software when playing the video. In other words, the video file can represent the video played by the target TV box through the target video software. By detecting the quality of the video file, the playback quality of the target video software when playing the video can be known. The playback quality can be characterized by picture clarity, smoothness, etc.

[0076] Because the video playback software of each manufacturer may do some processing on the film sources it owns, for example, for the same film source, video playback software A may process it for clarity and obtain the processed film source video file, and the film source video file is usually encrypted and cannot be obtained. Video playback software B may process it for smoothness, and the processed film source video file is also encrypted and cannot be obtained.

[0077] When the target TV box plays a certain video, since the source video file is generally encrypted, the target video software installed on the target TV box can be used to decrypt the source video file to obtain the decrypted video stream, and then the target TV box can transfer the video stream to the video capture card. The present application directly captures the video stream through the video capture card to generate a video file. The video file is basically the same as the encrypted source video file, and the picture quality is not much different, that is, the captured video file can be closer to the source video file, and restore the picture quality effect closer to the source. When the video file is used to detect the playback quality of the target video software when playing the video, the detection effect is more accurate. In short, the video file captured in this way can represent the playback status of a certain video software when playing the video, such as picture clarity, smoothness, etc., which is convenient for subsequent optimization of the video, and there is no need to manually record the source, which improves the detection efficiency and detection accuracy.

[0078] The video file can be directly stored in the hard disk of the terminal device so that the detection efficiency can be improved in the subsequent video detection. The video file can also be stored in other servers, so that large video files can be prevented from occupying more storage space of the terminal device.

[0079] In a possible implementation, the first script file may further include a third identifier of the server, where the third identifier is used to uniquely identify the server so that the server and the terminal device can communicate with each other. The method may further include S201-S202.

[0080] S201, generating a storage request through a first script file.

[0081] During the process of running the first script file, the terminal device may also generate a storage request, in which the storage request carries the third identifier of the terminal device and the video file.

[0082] S202: Send a storage request to the server based on the third identifier.

[0083] The third identifier can be used to determine which server the terminal device can send a storage request to, that is, the terminal device can send a storage request to the server corresponding to the third identifier according to the third identifier. The storage request can be used to request the server to store the video file, that is, after receiving the storage request, the server can store the video file carried in the storage request. In actual applications, the server can be a cloud server, so that the video file is uploaded to the cloud for storage.

[0084] From this, we can see that by uploading video files to the server for storage, the storage pressure of the terminal device can be reduced, especially when the video files are large, it can avoid the situation where the video files cannot be stored due to insufficient storage space of the terminal device. In addition, when collecting video files of multiple videos at one time, it can ensure that all video files can be stored normally and no file damage will occur.

[0085] After the video file is stored in the server, if the video file needs to be detected, the video file can be obtained from the server. In a possible implementation, the method further includes S301-S304.

[0086] S301, based on the triggering operation of the video detection task, obtaining a second script file corresponding to the video detection task.

[0087] Specifically, the video detection task can be understood as a task of performing quality detection on a video file. Based on a triggering operation on the task, the terminal device can obtain a second script file corresponding to the task.

[0088] The triggering operation of the video detection task can be an operation such as clicking on the video detection task control. By clicking the control, the task is triggered. Similarly, the video detection task can also be triggered in the task management webpage. There is a video detection task control in the task management webpage. When the user clicks the control, it means that the video detection task is triggered. Of course, it can also be triggered at a scheduled time.

[0089] When the task management webpage is deployed on a terminal device with a video capture card installed, the terminal device can directly receive the user's trigger operation on the video detection task, and based on the trigger operation, the second script file stored locally can be retrieved, that is, the second script file can be obtained. The correspondence between the video detection task and the second script file can be stored on the terminal device, so that the second script file can be found based on the correspondence.

[0090] When the task management webpage is deployed on another terminal device, the correspondence between the video detection task and the second script file is also stored on this terminal device. When this terminal device receives a trigger operation on the video detection task by the user, it can find the corresponding second script file based on the trigger operation and send it to the terminal device with a video capture card installed, so that the terminal device with a video capture card installed can obtain the second script file.

[0091] The second script file may include a third identifier of the server so as to determine which server stores the video file.

[0092] S302: Generate a video acquisition request based on the second script file.

[0093] The terminal device can run the second script file, and during the running process, a video acquisition request can be generated, and the video acquisition request carries the third identifier and the storage address of the video file. The third identifier is used to determine which server to send the video acquisition request to, and the storage address of the video file is used to determine the specific storage location of the video file in the server.

[0094] S303: Send a video acquisition request to the server based on the third identifier.

[0095] The terminal device can determine the corresponding server based on the third identifier and send a video acquisition request to the server. The video acquisition request is used to request the server to return the video file based on the storage address. Therefore, after receiving the video acquisition request, the server can search for the corresponding video file according to the storage address carried in the request and return the video file to the terminal device.

[0096] S304, performing quality detection on the video file to obtain a detection result.

[0097] The terminal device can perform quality detection on the video file and obtain the detection result. The evaluation indicators of quality detection are not limited here, and can be clarity, smoothness, picture quality color, whether the picture texture details are rich, whether the edge details are sharp, etc. For example, 1080p video has better quality than 720p video.

[0098] In practical applications, an existing video detection tool may be used to perform video detection. During the running of the second script file, the video detection tool may be called to perform quality detection on the video file.

[0099] The detection result is used to indicate the playback quality of the target video software when playing the video. That is, the detection result of the video file can characterize the quality of the video when playing the video using the target video software, that is, it can indicate the quality of the source video file.

[0100] In this way, by obtaining the video from the server and detecting it, the need for detection at any time can be met, and during the running of the second script file, automatic detection can be achieved without manual uploading of video files and manual video detection, which greatly improves the efficiency of video detection.

[0101] In a possible implementation, the terminal device can be connected to multiple TV boxes, and the first script file can include multiple first identifiers, one first identifier is used to identify a target TV box, then S102 generates a first control instruction through the first script file, which can be specifically, generating multiple first control instructions through the first script file. S103 sends the first control instruction to the target TV box based on the first identifier, which can be specifically, based on the first corresponding relationship, sending the first control instruction to the target TV box corresponding to the first identifier.

[0102] Specifically, one or more video capture cards may be installed on the terminal device, and the terminal device may be connected to multiple TV boxes via the one or more video capture cards, that is, one terminal device may control multiple TV boxes for video playback.

[0103] The first script file may include a plurality of first identifiers corresponding to a plurality of target TV boxes, that is, during the execution of the first script file, a plurality of target TV boxes may be controlled to play videos at the same time.

[0104] When the terminal device runs the first script file, it can generate multiple first control instructions, and the multiple first control instructions have a first corresponding relationship with the multiple first identifiers, that is, one first control instruction is used to control a target TV box, and the first identifier is used to determine which target TV box is controlled. Specifically, it can be understood that there are multiple script parts in the first script file, different script parts are used to generate different first control instructions, and the first control instruction has a corresponding relationship with the first identifier.

[0105] Furthermore, when sending multiple first control instructions to multiple target TV boxes, they can be sent according to the first corresponding relationship between them, that is, the first identifier corresponding to each first control instruction is determined, and then the first control instruction is sent to the target TV box identified by the first identifier. This ensures that the first control instruction can correctly control the target TV box, especially when the types of multiple target TV boxes are different, because the control processes of the corresponding video playback may also be different. Sending the first control instruction in this way can ensure that each target TV box can receive the correct first control instruction, and the first control instruction matches the type of the target TV box. In addition, by controlling multiple target TV boxes at the same time, the video streams of multiple videos can be collected at the same time, and parallel collection can be achieved, which greatly improves the efficiency of video collection.

[0106] In one possible implementation, multiple video capture cards are installed on the terminal device, and one video capture card is connected to one TV box. That is, one capture card can capture the video stream of one TV box. Installing multiple video capture cards can capture multiple video streams at the same time. S105 generates a video file based on the video stream, which can specifically include S1051-S1053.

[0107] S1051, determine the receiving port corresponding to each video stream.

[0108] When multiple video capture cards are installed on a terminal device, the terminal device can determine the port to which each video capture card is connected to the terminal device. The port is used to receive the video stream captured by the video capture card, so the port can be recorded as a receiving port, which is used to receive the video stream from the video capture card.

[0109] S1052: Determine the first identifier corresponding to each video stream based on the second corresponding relationship between the receiving port and the first identifier.

[0110] Specifically, since a video capture card is connected to a target TV box, a receiving port corresponds to a first identifier, and the corresponding relationship between the receiving port and the first identifier can be recorded as a second corresponding relationship. When the terminal device obtains multiple video streams, based on the one-to-one correspondence between the video stream and the video capture card, the video capture card corresponding to each video stream, that is, the corresponding receiving port, can be obtained, and then based on the second corresponding relationship, the first identifier corresponding to each video stream can be determined.

[0111] S1053: For each video stream, based on the video stream and the first identifier corresponding to the video stream, generate a video file corresponding to the first identifier.

[0112] When a terminal device generates multiple video files. For each video stream, based on the first identifier corresponding to the video stream, it can be determined which first identifier the generated video file corresponds to, that is, the corresponding relationship between each video file and each target TV box is determined, and then it can be known which target video software plays each video file. It is possible to correspond multiple video files to multiple target video software, ensuring that the video files will not be mistakenly corresponded to other target video software, and improving the accuracy of the video files representing the playback quality of the target video software.

[0113] In a possible implementation, the first control instruction may further include a fourth identifier of the target video, where the fourth identifier is used to uniquely identify a video in the target video software, that is, it may be possible to specify the capture of a video stream of a certain video.

[0114] The first control instruction is also used to instruct the target TV box to play the target video through the target video software based on the fourth identifier. That is to say, when the target TV box receives the instruction, it can determine the target video from a large number of videos in the target video software for playback based on the fourth identifier carried in the instruction.

[0115] Then S104 obtains the video stream of the video output by the target TV box through the video capture card, which can be specifically, obtaining the video stream of the target video output by the target TV box through the video capture card. In this way, when the target TV box plays the target video, the video capture card can be used to obtain the video stream of the target video output by the target TV box. Thereby, the acquisition requirements for specific videos can be met, personalized acquisition can be achieved, and the image quality detection for a specific video can be achieved, and the image quality detection is more targeted.

[0116] refer to Figure 2 As shown, it is an interactive schematic diagram of a video quality detection method provided in an embodiment of the present application, including S401-S415.

[0117] When acquiring the video file, the terminal device equipped with the video capture card may execute S401-S403.
