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 application.
As shown in fig. 1, the present embodiment provides a video access gateway 10. The video access gateway 10 may be in communication connection with a video matrix device (or a video source device capable of outputting an analog signal) and a terminal device, respectively, and is configured to process a video stream output by the video matrix device and output the processed video stream to the terminal device, so that the terminal device plays the video stream.
In detail, the video access gateway 10 may include an analog-to-digital converter 12 and a processor 14. The analog-to-digital converter 12 may be communicatively connected to the video matrix device, and is configured to receive a video stream (the video stream is an analog signal) output by the video matrix device and perform an analog-to-digital conversion process on the video stream (the processed video stream is a digital signal). The processor 14 may also be communicatively coupled to the analog-to-digital converter 12 for obtaining an analog-to-digital converted processed video stream.
The analog-to-digital converter 12 is configured with a target access interface, so that the processor 14 can obtain a video stream obtained by analog-to-digital conversion through the target access interface for processing based on a transmission protocol matched with the target access interface.
It should be noted that the specific type of the video stream is not limited, and may be selected according to the actual application requirements.
For example, in an alternative example, the video stream may be surveillance video (e.g., obtained by capturing a surveillance object via an image capture device communicatively coupled to the video matrix device). Therefore, the video stream is played through the terminal equipment, so that a user can monitor the corresponding monitored object.
Optionally, the specific type of the analog-to-digital converter 12 is not limited, and may be selected according to the requirements of the actual application.
For example, in an alternative example, the analog-to-digital converter 12 may be a hardware encoder model DS-6701 HFH. For another example, in another alternative example, the analog-to-digital converter 12 may also be another device having an analog-to-digital conversion function, as long as the target access interface can be provided and the transmission protocol is supported.
Optionally, the specific type of the processor 14 is not limited, and may be selected according to the actual application requirements.
For example, in an alternative example, the processor 14 may be a Central Processing Unit (CPU). For another example, in another alternative example, the processor 14 may also be a Graphics Processing Unit (GPU).
The specific type of the target access interface is also not limited, and may be, for example, a real-time streaming access interface (RTSP interface) or a real-time message access interface (RTMP interface).
Correspondingly, the specific type of the transmission Protocol is not limited, and may be, for example, a Real Time Streaming Protocol (RTSP) Protocol or a Real Time Messaging Protocol (RTMP) Protocol.
It is understood that the video access gateway 10 may further include a memory 16 and a video processing device 100 stored on the memory 16.
In detail, the memory 16 and the processor 14 may be directly or indirectly electrically connected to realize data transmission or interaction. For example, they may be electrically connected to each other via one or more communication buses or signal lines. The video processing apparatus 100 includes at least one software functional module that can be stored in the memory 16 in the form of software or firmware (firmware). The processor 14 is configured to execute executable computer programs stored in the memory 16, such as software functional modules and computer programs included in the video processing apparatus 100, so as to implement the video processing method provided by the embodiment of the present application.
The Memory 16 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.
It should be noted that the structure shown in fig. 1 is only an illustration, and the video access gateway 10 may further include more or fewer components than those shown in fig. 1, or have a different configuration from that shown in fig. 1, for example, may further include a communication unit for information interaction with other devices.
With reference to fig. 2, an embodiment of the present application further provides a video processing method applicable to the processor 14 of the video access gateway 10. Wherein the video access gateway 10 further comprises an analog-to-digital converter 12 communicatively connected to the processor 14, the analog-to-digital converter 12 is configured with a target access interface, and the method steps defined by the flow related to the video processing method can be implemented by the processor 14. The specific process shown in fig. 2 will be described in detail below.
Step S110, obtaining the to-be-processed video stream converted by the analog-to-digital converter 12 from the target access interface based on a preset transmission protocol.
In this embodiment, the transmission protocol is matched with the target access interface, so that the processor 14 can obtain the video stream to be processed (i.e. the digital video stream converted by the analog-to-digital converter 12) from the target access interface based on the transmission protocol.
That is, the processor 14 may perform a stream fetching operation from the target access interface based on the transmission protocol to obtain the to-be-processed video stream.
Step S120, decoding the video stream to be processed, and performing rotation processing on the first video stream obtained by decoding based on the acquired angle information.
In this embodiment, after the to-be-processed video stream is obtained in step S110, the to-be-processed video stream may be decoded first. Then, the first video stream obtained by decoding is subjected to rotation processing based on the acquired angle information.
Step S130, performing encoding processing on the first video stream after the rotation processing, and outputting a second video stream obtained by encoding.
In this embodiment, after the rotated first video stream is obtained in step S120, the first video stream may be encoded to obtain a second video stream. Then, the second video stream is output.
Based on the above method, on one hand, since the angle conversion process (the rotation process based on the angle information) is performed at the video access gateway 10, it is not necessary to design different conversion schemes according to different player terminals (such as the above terminal devices). On the other hand, the acquired video stream to be processed has a uniform protocol (such as the preset transmission protocol), so that a plurality of transcoding or output schemes are not required to be configured in advance in the transcoding and outputting process. Therefore, the video processing method can solve the problem of poor universality in the existing video stream processing technology.
Optionally, the specific manner of obtaining the video to be processed based on step S110 is not limited, and may be selected according to the actual application requirement.
For example, in an alternative example, the target access interface may be a real-time stream access interface, and correspondingly, step S110 may include the following sub-steps: and acquiring the to-be-processed video stream converted by the analog-to-digital converter 12 from the real-time stream access interface based on a preset real-time stream transmission protocol.
That is, the processor 14 may perform a stream fetching operation from the real-time stream access interface based on the real-time streaming protocol, so as to obtain the to-be-processed video stream.
For another example, in another alternative example, the target access interface may be a real-time message access interface, and correspondingly, step S110 may include the following sub-steps: and acquiring the video stream to be processed converted by the analog-to-digital converter 12 from the real-time message access interface based on a preset real-time message transmission protocol.
That is, the processor 14 may perform a stream fetching operation from the real-time message access interface based on the real-time message transmission protocol, so as to obtain the to-be-processed video stream.
It should be noted that, when the processor 14 performs a flow fetching operation, the processor 14 may further determine, based on a preset configuration file, a number of ways to fetch a flow and an initial address, so as to perform the flow fetching operation based on the number of ways and the initial address.
Optionally, the way of performing the rotation processing on the first video stream based on step S120 is also not limited, and may be selected according to the actual application requirement.
For example, in an alternative example, the rotation process for the first video stream may be completed based on performing a rotation assignment operation on each video frame in the first video stream.
In detail, referring to fig. 3, a certain video frame of the first video stream includes 4 vertices A, B, C and D, and the corresponding coordinates may be (0, 0), (2, 1) and (0, 1). Thus, after the video frame is rotated 90 degrees clockwise, the coordinates corresponding to A, B, C and D are (1, 0), (1, 2), (0, 2), and (0, 0), respectively.
Optionally, the manner of encoding the rotation-processed first video stream based on step S130 is also not limited, and may be selected according to the actual application requirement.
For example, in an alternative example, the first video stream may be encoded in YUV420 data format to obtain the second video stream.
Moreover, the specific manner of outputting the second video stream based on step S130 is not limited, and may be selected according to the actual application requirements.
For example, in an alternative example, in order to enable the output second video stream to be played on more playing devices (such as the terminal device described above), so as to further improve the versatility of the video processing method described above, step S130 may include the following sub-steps: and outputting the second video stream obtained by encoding to a target position based on a real-time message transmission protocol.
That is to say, a protocol header conforming to the real-time messaging protocol may be added to the second video stream, and then, an address of the target location is obtained from a preset configuration file, and stream pushing processing is performed based on the address, so as to output the address to the target location.
The target position may refer to a streaming media soft switching controller, so that the streaming media soft switching controller may forward the second video stream to a playing device (or, the playing device may perform a streaming operation from the streaming media soft switching controller to obtain the second video stream).
The streaming media soft switching controller may refer to a software function module formed by a computer program stored in the video access gateway 10, or may refer to a software function module formed on a streaming media server communicatively connected to the video access gateway 10.
That is, the software functional module corresponding to the streaming media soft switching controller may be configured in the video access gateway 10, or may be configured in a streaming media server communicatively connected to the video access gateway 10.
In addition, in order to facilitate the playing device to perform an effective stream fetching operation on the streaming media soft switch controller, after the processor 14 outputs the second video stream to the streaming media soft switch controller, a push address may be generated based on an address of the streaming media soft switch controller and time information for performing encoding processing, so that after the playing device acquires the push address, the playing device may perform an effective stream fetching operation on the streaming media soft switch controller based on the push address.
Further, considering that in step S120, the decoded first video stream needs to be subjected to rotation processing based on the acquired angle information, the video processing method may further include the following steps: and acquiring the angle information based on a preset angle acquisition rule.
The specific content of the angle acquisition rule is not limited, and can be selected according to the actual application requirements.
For example, in an alternative example, the corresponding angle information may be set in a preset configuration file. Then, when the first video stream needs to be rotated, the configuration file is directly read to obtain the angle information.
For another example, in another alternative example, the corresponding angle information may be obtained based on an instruction generated by an operation of a user. In detail, the step of acquiring the angle information may include the sub-steps of:
firstly, whether an angle replacing instruction generated based on user operation is received in a preset time length can be judged; secondly, if the angle change instruction is received within the preset time, the angle information can be obtained based on the angle change instruction.
That is, as long as the angle change instruction is received within the preset time period, the corresponding angle information is determined based on the angle change instruction, and then the corresponding rotation processing is performed based on the angle information.
The receiving of the angle change instruction within the preset time period may be receiving the angle change instruction within a period of time before the rotation process needs to be started.
For example, if the preset time period is 30 minutes, the time required to start the rotation process is 16 o 'clock 23 o' clock 2019, and thus, if the angle change instruction is received between 15 o 'clock 40 o' clock 23 o 'clock 2019 and 23 o' clock 16 o 'clock 10 o' clock 2019, then the corresponding angle information is determined based on the angle change instruction, and the angle information includes, but is not limited to, 45 degrees, 90 degrees, 180 degrees, 270 degrees, and the like).
It should be noted that the specific value of the preset duration is not limited, and may be selected according to the actual application requirement. For example, it may be 30 minutes as described above, or it may be other time periods, such as 5 minutes, 1 minute, or 30 seconds.
Further, based on the foregoing determining step, if it is determined that the angle change instruction is not received within the preset duration, the manner of obtaining the angle information is not limited.
For example, in an alternative example, when it is determined that the angle change instruction is not received within the preset time period, the angle information determined to correspond to the most recently received angle change instruction may be acquired.
For another example, in another alternative example, when it is determined that the angle change instruction is not received within the preset time period, a preset configuration file may be obtained, and the angle information may be obtained based on the configuration file.
That is, in a specific application example, when receiving an instruction from a user, angle information may be determined based on the instruction from the user, and corresponding rotation processing may be performed based on the angle information. If the instruction of the user is not received, corresponding rotation processing can be carried out based on the preset angle information.
Therefore, on the basis of ensuring that the first video stream after decoding processing can be subjected to rotation processing at a certain angle, the first video stream after decoding processing can be subjected to rotation processing at a certain angle according to the requirements of users, the practical value of the video processing method is effectively improved, and the requirements of different users can be met.
The manner of receiving the angle change instruction is not limited, and for example, a TCP (Transmission Control Protocol) command generated and transmitted by another device in response to the operation of the user may be received through a configured TCP Control interface. That is, the angle change instruction may be a TCP command received.
With reference to fig. 4, the embodiment of the present application further provides a video processing apparatus 100 applicable to the processor 14 of the video access gateway 10. The video access gateway 10 further includes an analog-to-digital converter 12 communicatively connected to the processor 14, the analog-to-digital converter 12 is configured with a target access interface, and the video processing apparatus 100 may include a video acquisition module 110, a video rotation module 120, and a video output module 130.
The video obtaining module 110 is configured to obtain, from the target access interface, a to-be-processed video stream obtained by converting by the analog-to-digital converter 12 based on a preset transmission protocol, where the transmission protocol is matched with the target access interface. In this embodiment, the video obtaining module 110 may be configured to perform step S110 shown in fig. 2, and reference may be made to the foregoing description of step S110 regarding relevant contents of the video obtaining module 110.
The video rotation module 120 is configured to decode the video stream to be processed, and perform rotation processing on a first video stream obtained by decoding based on the obtained angle information. In this embodiment, the video rotation module 120 may be configured to perform step S120 shown in fig. 2, and reference may be made to the foregoing description of step S120 for relevant contents of the video rotation module 120.
The video output module 130 is configured to perform encoding processing on the first video stream after the rotation processing, and output a second video stream obtained by encoding. In this embodiment, the video output module 130 can be configured to perform step S130 shown in fig. 2, and reference may be made to the foregoing description of step S130 for relevant contents of the video output module 130.
It should be noted that the specific role of the video capture module 110 may also be different based on the specific type of the target access interface configured on the analog-to-digital converter 12.
For example, in an alternative example, the target access interface may be a real-time streaming access interface (RTSP interface), and the video obtaining module 110 may be specifically configured to obtain, based on a preset real-time streaming protocol, the to-be-processed video stream converted by the analog-to-digital converter 12 from the real-time streaming access interface.
For another example, in another alternative example, the target access interface may be a real-time messaging access interface (RTMP interface), and the video acquiring module 110 may be specifically configured to acquire the to-be-processed video stream converted by the analog-to-digital converter 12 from the real-time messaging access interface based on a preset real-time messaging protocol.
In an embodiment of the present application, there is also provided a computer-readable storage medium, in which a computer program is stored, and the computer program executes the steps of the video processing method when running.
Here, the steps executed when the computer program runs are not described in detail, and reference may be made to the foregoing explanation of the video processing method.
To sum up, the video processing method and apparatus, the video access gateway, and the storage medium provided by the present application set a transmission protocol and a target access interface that are matched with each other, and then obtain a video stream to be processed through the target access interface based on the transmission protocol and perform corresponding rotation processing (angle conversion processing) and output. Therefore, on one hand, since the angle conversion processing is completed in the video access gateway 10, different conversion schemes do not need to be designed according to different player terminals; on the other hand, the acquired video stream to be processed has a uniform protocol, so that a plurality of transcoding or output schemes are not required to be configured in advance in the transcoding and outputting process. Therefore, the technical scheme provided by the application can be used for solving the problem of poor universality existing in the existing video stream processing technology.
