Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a video composition testing method according to an embodiment of the present invention, the method including the following steps:
s101, video code streams fed back to a target terminal by the multipoint conference controller are obtained.
The video code stream is obtained by synthesizing and encoding preset video sources input by each current participating terminal by the multipoint conference controller.
As shown in fig. 2, in practical applications, a stream detection server may be configured to obtain a video stream. In fig. 2, MTn is a participant terminal.
In this embodiment, a preset video source may be preset for each participant terminal, and the preset video source of each participant terminal is different and can be identified and distinguished. For example, the preset video source may be a human face video, or may be different object videos.
When testing is carried out, each participating terminal sends the corresponding preset video source to the multipoint conference controller, and the multipoint conference controller synthesizes and codes the preset video source of each participating terminal based on the current conference information to obtain a video code stream. It should be noted that the multipoint conference controller may synthesize the preset video sources of all the participating terminals based on the conference information, and the multipoint conference controller may also synthesize the preset video sources of some of the participating terminals based on the conference information.
After the multipoint conference controller obtains the video code stream, the video code stream can be sent to each participating terminal. If there are participant terminals MT1, mt2.. MTn, the video stream transmitting ports in the MCU are: p1, P2.. Pn; selecting the picture synthesis image condition received at the current spot inspection MTn terminal, wherein the port is Pn; i.e. the video stream is obtained from the Pn port.
The target terminal is any one of the participant terminals in the received video code stream.
Specifically, the network firewall can be used to obtain the video code stream. Namely, the video code stream is acquired through an IPtable (network firewall). Specifically, the IPtable may forward the video code stream sent to the target terminal to the detection device.
S102, decoding the video code stream to obtain a composite video.
After the video code stream is obtained, the video code stream can be decoded, and the decoding result is the synthesized video. In particular, the composite video may be embodied as data in a yuv format (a color coding format).
S103, identifying the synthesized video, and determining an actual terminal set of the synthesized video by using the identification result.
After the composite video is obtained, the composite video can be identified, namely, which preset video sources are used for synthesizing the composite video are identified, and then, according to the corresponding relation between the preset video sources and the participant terminals, which videos sent by the participant terminals are used for video synthesis can be determined. Each participant terminal determined based on composite video recognition is considered as an element in the set of actual terminals in the present application. That is, each element in the actual terminal set refers to one terminal participating in the video composition.
Preferably, a human face can be used as a video source, and the video content is identified and perceived by the human face in the video source, so that the requirements of an actual meeting scene can be better met. Specifically, each preset video source is a single face video source, and each preset video source corresponds to one participant terminal; a real terminal set determination process comprising:
step one, carrying out face recognition on the synthesized video to obtain a face recognition result;
and step two, determining an actual terminal set corresponding to the face recognition result according to the corresponding relation among the face, the preset video source and the participant terminal.
For convenience of description, the above two steps will be described in combination.
After the synthetic video is obtained, face recognition can be performed on the synthetic video to obtain a face recognition result. And then, according to the corresponding relation among the three types of faces, a single face video source and the participant terminals, determining an actual terminal set corresponding to the face recognition result.
And S104, judging whether the actual terminal set is consistent with the expected terminal set.
Each element in the expected terminal set refers to a participant terminal, and a preset video source of the participant terminal needs to participate in video synthesis.
The process of obtaining the set of expected terminals may include:
acquiring current conference information by using a remote login service protocol;
and step two, determining an expected terminal set for generating the picture by using the conference information.
For convenience of description, the above two steps will be described in combination.
The current conference information obtained from the multipoint conference controller may be obtained using a telnet protocol. The current conference information may specifically include a port number of the current participant terminal, conference moderator information, and a port number, an ID, and a terminal name of the participant terminal that needs to participate in the picture composition. For example, the conference information includes a desired terminal set corresponding to a terminal name in screen composition, such as set M, including MT1 and mt2.. MTn.
And judging whether the actual terminal set is consistent with the expected terminal set or not, namely judging whether the video synthesis is performed according to the expectation at present or not. For example, the following steps are carried out: if the desired terminal set M includes: MT1, mt2.. MTn; the actual terminal set N includes: MT1, mt2.. MTm; and M corresponds to each element in N one to one, the actual terminal set is determined to be consistent with the expected terminal set, otherwise, the actual terminal set is not consistent with the expected terminal set.
Preferably, in order to improve the determination efficiency, the following steps may be performed to determine whether the actual terminal set is consistent with the expected terminal set, and may specifically include:
step one, judging whether the element quantity of an actual terminal set is the same as that of an expected terminal set;
step two, if not, determining that the actual terminal set is inconsistent with the expected terminal set;
if yes, judging whether each element of the actual terminal set is the same as each element of the expected terminal set;
step four, if all elements are the same, determining that the actual terminal set is consistent with the expected terminal set;
and step five, if different elements exist, determining that the actual terminal set is inconsistent with the expected terminal set.
That is, it may be determined whether the number of elements in the actual terminal set is consistent with that in the expected terminal set, and if the number of elements is not consistent, it may be directly determined that the actual terminal set is not consistent with that in the expected terminal set; and when the number of the elements of the actual terminal set is consistent with that of the expected terminal set, whether the elements in the two sets are in one-to-one correspondence can be further compared. If the terminal sets correspond to each other, determining that the actual terminal set is consistent with the expected terminal set; and if the terminal sets are not in one-to-one correspondence, determining that the actual terminal set is inconsistent with the expected terminal set.
For example, the following steps are carried out: if the desired terminal set M includes MT1, mt2.. MTn; the actual terminal set N includes: MT1, mt2.. MTm; if M and N are not consistent, directly determining that M is not equal to N; if M is equal to N, further judging whether M corresponds to N one by one; if so, determining that the actual terminal set is consistent with the expected terminal set; if not, the actual terminal set is inconsistent with the expected terminal set.
And after a judgment result of whether the actual terminal set is consistent with the expected terminal set is obtained, whether the video synthesis at the target terminal is normal can be determined. Specifically, if the determination result is yes, the operation of step S105 is executed; if the determination result is negative, the operation of step S106 is executed.
And S105, determining that the video synthesis detection result at the target terminal is normal.
When the actual terminal set is consistent with the expected terminal set, i.e. the current video composition is performed as expected, it can be determined that the video composition at the target terminal is normal. The video composition at the target terminal is normal, that is, the composite video obtained by the target terminal is in accordance with the expectation.
S106, determining that the video synthesis detection result at the target terminal is abnormal.
And when the actual terminal set is inconsistent with the expected terminal set, namely the current video synthesis is not performed according to the expectation, determining that the video synthesis at the target terminal is abnormal. The video composition anomaly at the target terminal means that the composite video obtained by the target terminal is not expected. The reason for the non-expectation may be that the target terminal has a problem communicating with the multipoint conference controller, that the multipoint conference controller is synthesized, or that the other participating terminals have a problem communicating with the multipoint conference controller.
Preferably, after determining the video synthesis abnormality at the target terminal, the factor causing the video synthesis abnormality may be further estimated. The specific implementation process comprises the following steps:
acquiring difference information of an actual terminal set and an expected terminal set;
and step two, determining factors causing video synthesis abnormity by using the difference information.
The difference information between the actual terminal set and the expected terminal set can be stored when judging whether the actual terminal set is consistent with the expected terminal set, and the difference information can be directly obtained by reading when tracing the factors causing the abnormal video synthesis. Of course, when the factor causing the video synthesis abnormality can be traced, the difference information can be obtained by comparing the difference between the actual terminal set and the expected terminal set.
The difference information may specifically be a difference in the number of elements and/or a difference in the elements themselves, that is, the difference in the number of elements may be used alone, for example, the number of the participating terminals in the actual terminal set is 2 less than that in the expected terminal set; differences of elements themselves can also be used, such as the name of the terminal participating in the synthesis is wrong when the actual terminal set is compared with the expected terminal set; the number of differences and the names of the terminals of the differences can also be found.
After the difference information is obtained, factors of video synthesis abnormity (such as communication problems and problems of the multipoint conference controller) can be estimated.
For example, when the expected terminal set includes four elements a1, a2, a3 and a4, and the actual terminal set includes three elements a1, a2 and a4, the comparison result is that the element difference is 1, and the element itself is different, that is, the actual terminal set lacks a 3; at this time, the source of the video synthesis exception can be traced based on a3, such as the communication exception between a3 and the multipoint conference controller, and the multipoint conference controller exception can also be performed.
Preferably, in order to improve the detection accuracy, and the precise positioning is a video synthesis abnormal factor. In this embodiment, video composition detection may also be performed for a plurality of participant terminals, respectively. Specifically, after the video synthesis detection result of the target terminal is obtained, the following steps may be further performed:
step one, judging whether a participant terminal to be detected exists or not;
step two, if yes, re-determining a target terminal from the participant terminals to be tested, and executing the step of obtaining the video code stream fed back to the target terminal by the multipoint conference controller;
and step three, if not, counting video synthesis detection results corresponding to all the participant terminals to be detected.
In practical application, each current participant terminal can be used as a participant terminal to be tested. When the video synthesis detection at one participating terminal is finished, the appointed port number can be recorded, and whether the participating terminal to be detected exists can be determined by searching the port number. Or sequentially taking each participating terminal as a target terminal, sequentially executing the steps S101-S105 or S106 to perform video synthesis detection, and then counting the video synthesis detection results at each participating terminal to obtain a statistical result, wherein the statistical result is based on the overall quality of the current picture synthesis of the conference system.
Preferably, in case of a large number of participating terminals, a spot check may be performed to avoid consuming a large amount of resources and time. Specifically, when the target terminal is determined, the participant terminal to be tested is screened out from each current participant terminal. Specifically, according to the actual detection requirement, part of the parameter terminals in the current participating terminals, for example, 60% of the total number of participating terminals, or a specified number, for example, 20, may be randomly sampled and detected.
By applying the method provided by the embodiment of the invention, the video code stream fed back to the target terminal by the multipoint conference controller is obtained; the video code stream is obtained by synthesizing and encoding preset video sources input by each current participating terminal by the multipoint conference controller; decoding the video code stream to obtain a synthesized video; identifying the synthesized video, and determining an actual terminal set of the synthesized video by using an identification result; judging whether the actual terminal set is consistent with the expected terminal set; if so, determining that the video synthesis detection result at the target terminal is normal; if not, determining that the video synthesis detection result is abnormal.
Each participant terminal corresponds to a preset video source, each participant terminal sends the preset video source to the multipoint conference controller in the testing process, and then the multipoint conference controller carries out picture synthesis based on each preset video source, namely video synthesis and coding feedback to each participant terminal. And acquiring a video code stream in the target terminal, and then decoding to obtain a composite video. Then, the composite video is identified, and the preset video sources sent by the participant terminals can be determined to be used by the composite video. The actual set of terminals for the composite video can be determined. And then judging whether the actual terminal set is consistent with the expected terminal set, if so, indicating that the video synthesis at the target terminal is normal, otherwise, judging that the video synthesis is abnormal. Therefore, in the method, manual interference is not needed, the video synthesis effect can be automatically detected, the detection efficiency can be improved compared with manual detection, and the copying test and the high-capacity test can be realized.
