Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flow chart illustrating a video communication method, which may be applied to a processor of a terminal, according to an example embodiment. As shown in FIG. 1, the method includes S101-S104.
In S101, when the terminal performs video communication, whether a video stream transmitted by the target image capturing device via the communication bus is interrupted is detected in real time.
In the present disclosure, the video communication may be a video conference, a video call, a live video, and the like. The terminal includes a processor and at least one image acquisition device (e.g., a camera). During video communication, at least one image acquisition device on the terminal acquires a video picture of the current video communication, and equipment used for acquiring the video picture of the video communication in the terminal is target image acquisition equipment. The target image acquisition device continuously transmits the video pictures to a processor of the terminal through a communication bus after acquiring the video pictures to form a video stream, the processor of the terminal receives the video stream, encodes the video stream, transmits the encoded video stream to a communication opposite terminal, and simultaneously can display the video stream on a display module of the current terminal.
In S102, it is determined whether the video stream is abnormal according to the detection result of whether the video stream is interrupted.
In S103, if it is determined that the video stream is abnormal, whether the communication bus is normal is detected in real time.
In S104, if it is detected that the communication bus is normal, the target image capturing device is controlled to be reset.
In the present disclosure, if it is determined that the video stream is normal according to the detection result of whether the video stream is interrupted, continuing to detect whether the video stream is interrupted, that is, continuing to execute S101; and if the video stream is determined to be abnormal according to the detection result of whether the video stream is interrupted, detecting whether the communication bus is normal in real time, and controlling the target image acquisition device to reset when the communication bus is normal, namely initializing the configuration parameters of the target image acquisition device so as to automatically acquire the video image of the current video communication again after the target image acquisition device is reset.
Specifically, during video communication, if a video stream is abnormal, the video stream may be caused by an abnormal operation of the target image acquisition device or an abnormal operation of the communication bus, and therefore, when the video stream is determined to be abnormal, it is necessary to exclude whether the abnormal operation is caused by the abnormal operation of the communication bus. If the communication bus is normal, the video stream abnormity is not caused by the communication bus abnormity, but caused by the target image acquisition device working abnormity, and at the moment, the target image acquisition device can be controlled to reset.
In the above technical solution, when a terminal performs video communication (for example, a video conference), whether a video stream transmitted by a target image acquisition device for acquiring a video picture of the video communication via a communication bus in the terminal is interrupted or not is detected in real time; if the video stream is determined to be abnormal according to the detection result of whether the video stream is interrupted, detecting whether the communication bus is normal in real time; and if the communication bus is detected to be normal, controlling the target image acquisition device to reset. Therefore, after the target image acquisition device for acquiring the video image of the current video communication is reset, the video image can be automatically acquired again, the abnormal self-recovery of the video stream is realized, the user does not need to manually restart the video communication application, even the video communication terminal is restarted in power failure, the time cost for restarting the video communication application or restarting the terminal in power failure is saved, the actions of video communication reconnection, communication configuration and the like do not need to be carried out after the restart, the device is simple and efficient, great convenience and practicability are brought to the remote video communication of the user, and the flexibility and the intelligence of the video communication are improved. In addition, the target image acquisition device transmits the video stream to the processor of the terminal through a communication bus, wherein the video stream abnormality may be caused by the communication bus abnormality. When the video stream abnormity is caused by the communication bus abnormity, the problem of the video stream abnormity cannot be solved by resetting the target image acquisition device, therefore, when the communication bus abnormity is detected, the target image acquisition device is controlled to reset, the condition that the video stream abnormity is caused by the communication bus abnormity can be eliminated, and the situation that the target image acquisition device cannot acquire video pictures again after being reset is avoided.
The following describes in detail a specific embodiment of detecting in real time whether the video stream transmitted by the target image capturing device via the communication bus is interrupted in S101.
In one embodiment, it may be detected in real time whether the latest two video frames in the video stream are the same, and if the latest two video frames are detected to be the same for a plurality of consecutive times (e.g., three times), it is determined that the video stream is interrupted; otherwise, it is determined that the video stream is not interrupted.
In another embodiment, a flag bit is stored in a predetermined register in the terminal, wherein the flag bit changes with a change of a video frame in a video stream transmitted by the target image capturing device via the communication bus. In this way, whether the video stream is interrupted or not can be determined by detecting whether the flag bit changes within a preset time period before the current time. Specifically, if the flag bit is not changed within a preset time before the current time, determining that the video stream is interrupted; and if the flag bit is changed within a preset time before the current moment, determining that the video stream is not interrupted. Therefore, whether the video stream is interrupted or not can be determined in a hardware detection mode, and convenience and rapidness are achieved.
The following describes in detail a specific embodiment of determining whether the video stream is abnormal according to the detection result of whether the video stream is interrupted in S102.
In one embodiment, a video stream anomaly is determined upon detection of a video stream interruption.
However, when the video stream is interrupted due to the occasional working abnormality of the target image acquisition device or the communication bus, the subsequent video stream interruption can be automatically recovered, and at this time, the video stream is not considered to be abnormal and the video stream abnormality does not need to be processed. Therefore, in order to eliminate the problem of video stream interruption caused by occasional abnormality of the target image acquisition device or the communication bus, the video stream abnormality may be determined only when the number of times of continuously detecting the video stream interruption reaches a certain number of times, and at this time, the video stream abnormality needs to be processed. Specifically, in another embodiment, if the number of times of continuously detecting the interruption of the video stream reaches a first preset number threshold, it is determined that the video stream is abnormal; otherwise, determining that the video stream is normal. Wherein the first preset number threshold is greater than 1, exemplarily equal to 3.
In addition, if the communication bus is abnormal, it indicates that the video stream abnormality may be caused by the communication bus abnormality, or may be caused by the reset image acquisition device, and at this time, the problem of the video stream abnormality cannot be solved by resetting the target image acquisition device, and a video communication application (for example, a video conference application program) for realizing the video communication is required to be restarted to solve the problem. Specifically, as shown in fig. 2, the method further includes S105.
In S105, if the detection result of whether the communication bus is normal satisfies the preset condition, the video communication application in the control terminal for implementing video communication is restarted.
In one embodiment, the preset condition is a communication bus abnormality, that is, once the communication bus abnormality is detected, the video communication application in the control terminal for implementing video communication is restarted.
In addition, when the video stream is interrupted due to the occasional work abnormality of the communication bus, the subsequent video stream interruption can be automatically recovered, and at the moment, the video communication application does not need to be restarted. Therefore, in order to eliminate the problem of video stream interruption caused by the occasional abnormality of the communication bus, the video communication application can be controlled to restart when the number of times of continuously detecting the abnormality of the communication bus reaches a certain number. Specifically, in another embodiment, the preset condition is that the number of times of continuously detecting the communication bus abnormality reaches a second preset number threshold. Namely, when the number of times of continuously detecting the communication bus abnormality reaches a second preset number threshold, the video communication application in the terminal for realizing the video communication is controlled to restart. Wherein the second preset number threshold is greater than 1, exemplarily equal to 3.
In addition, in the video communication process, besides the video stream interruption caused by the abnormal operation of the corresponding target image acquisition device and the abnormal communication bus, the video stream interruption may be caused by the static electricity of the terminal. Therefore, the HDMI of the display module of the terminal can be subjected to anti-static processing. Specifically, as shown in fig. 3, a conductive reinforcement 13 may be disposed between the metal shell 11 of the terminal and the HDMI interface 12 of the display module of the terminal, and the conductive reinforcement 13 is in contact with the metal shell 11 and the HDMI interface 12, respectively. The conductive reinforcing member 13 may be, for example, a conductive cloth, a conductive foam, or the like.

As shown in fig. 4, the apparatus 400 includes: a first detection module 401, configured to detect whether a video stream transmitted by a target image acquisition device via a communication bus is interrupted in real time when the terminal performs video communication, where the target image acquisition device is a device in the terminal and configured to acquire a video image of the video communication; a determining module 402, configured to determine whether the video stream is abnormal according to a detection result of whether the video stream is interrupted detected by the first detecting module 401; a second detecting module 403, configured to detect whether the communication bus is normal in real time if the determining module 402 determines that the video stream is abnormal; a control module 404, configured to control the target image capturing device to reset if the second detecting module 403 detects that the communication bus is normal.
In the above technical solution, when a terminal performs video communication (for example, a video conference), whether a video stream transmitted by a target image acquisition device for acquiring a video picture of the video communication via a communication bus in the terminal is interrupted or not is detected in real time; if the video stream is determined to be abnormal according to the detection result of whether the video stream is interrupted, detecting whether the communication bus is normal in real time; and if the communication bus is detected to be normal, controlling the target image acquisition device to reset. Therefore, after the target image acquisition device for acquiring the video image of the current video communication is reset, the video image can be automatically acquired again, the abnormal self-recovery of the video stream is realized, the user does not need to manually restart the video communication application, even the video communication terminal is restarted in power failure, the time cost for restarting the video communication application or restarting the terminal in power failure is saved, the actions of video communication reconnection, communication configuration and the like do not need to be carried out after the restart, the device is simple and efficient, great convenience and practicability are brought to the remote video communication of the user, and the flexibility and the intelligence of the video communication are improved. In addition, the target image acquisition device transmits the video stream to the processor of the terminal through a communication bus, wherein the video stream abnormality may be caused by the communication bus abnormality.
