Detailed Description
The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.
Fig. 1 is a flowchart of a method for obtaining a start-up URL according to a first embodiment of the present application, where the present embodiment is applicable to a case of starting up a media stream based on a media transport protocol, and the method may be performed by a start-up URL obtaining apparatus, which may be implemented in a software and/or hardware manner and may be integrated in a client of an electronic device (e.g., a mobile terminal, a tablet computer, etc.).
As shown in fig. 1, the method for obtaining the start-up URL specifically includes the following steps:
S101, after receiving information of successfully logging in the equipment, inquiring whether an adapted file exists locally.
The device is optionally an encoding device which acquires, stores and manages video of each channel of camera through internet connection, for example, the device is an NVR device. The client installed in the electronic device (such as a mobile terminal, a tablet computer, etc.) can log in the device through a preset account number and a preset password, so as to view live video of any channel camera or play back monitoring video of a certain period of time on the client. In order to view live video or play back video, the client needs to acquire a start stream URL (uniform resource locator) to start a media stream, wherein the media stream includes a live stream and a play back stream, so that the efficiency of acquiring the start stream URL directly affects the speed of the client to start the media stream.
In the embodiment of the present application, in order to avoid that when a client requests a start-up URL from a device, because the network delay causes too long time for acquiring the start-up URL, the inventor creatively proposes a method for automatically generating the start-up URL locally through a locally stored adapted file, where the adapted file is based on the start-up URL acquired from the device side in advance and performs data analysis on the start-up URL, if a URL format and a parameter filling manner required by the device are obtained according to an analysis result, an adapted file is generated, otherwise, the adapted file is not generated, and the start-up URL is acquired according to the existing method. The adapted file comprises URL format and start-up parameter filling mode required by the verified device, namely the adapted file comprises a method for assembling the start-up URL, and verification is effective, so that the obtained adapted file is the method for obtaining the verified assembled URL.
In the embodiment of the present application, if a live stream is to be started, the start stream parameter includes a channel number and a stream number; if the playback stream is to be started, the stream starting parameter comprises a channel number and a stream number, and also comprises a start time and an end time; the stream number is used for representing the type of the opened live stream or the playback stream, the type of the stream comprises a main stream, an auxiliary stream, a third stream and the like, and the fact that the resolution, the mode and the like of different types of streams are different is needed to be described; the channel number is used to characterize from which channel camera the live or playback stream was turned on.
Illustratively, taking the example of opening a live stream, the open stream URL format is as follows: rtsp/(IP >: port >/unicast/< channel number >/< stream number >/live, where unicast and live are fixed fields. The filling modes of the start-up parameters comprise the modes of channel numbers and stream numbers, for example, 1 channel is represented by a numeral '0', and 2 channel is represented by 1; the primary stream is denoted by Main and the secondary stream is denoted by second.
It should be noted that, the URL formats and the start-up parameters required by different devices are different in filling modes, so that the locally pre-stored adapted files of the client side communicating with the devices are different for different devices, so that the client side can generate the start-up URL meeting the requirements of the devices according to different adapted files, thereby avoiding the compatibility problem existing when a fixed URL format is used for generating the start-up URL, for example, when the URL format is changed, format errors are caused, and finally the start-up failure is caused.
S102, if the media stream exists, entering an adapted state, locally assembling a local URL at the client by using the adapted file and the identified streaming parameters, and taking the local URL as the streaming URL so as to start the media stream based on the streaming URL.
The identified start-up parameters refer to start-up parameters specified by the user on the client. If the adapted file exists, the local URL is assembled locally at the client by utilizing the adapted file and the user-specified start-up parameters. Illustratively, for opening a live stream, the specified start-stream parameter is 1 channel (denoted by "0"), the main stream, then the generated start-stream URL: rtsp/(192.168.1.64:554/unicast/0/Main/live, where IP and port numbers are known. Further, the client opens the live stream using the local URL as a start-stream URL.
It should be noted that if the playback stream is to be started, a start time and an end time are also specified, where the start time and the end time may be represented by NTP time or UTC time. Illustratively, the start-up URL for the start-up playback stream generated locally at the client through S101-S102 is as follows: rtsp/(192.168.1.64:554/0/b 1593241643/e1593245776/replay/type1981/or/Main/; where b1593241643/e1593245776 denotes the start time/end time.
In the embodiment of the application, after the client successfully logs in the device, if the adapted file exists locally, the client enters an adapted state, wherein the adapted state represents a method for acquiring the assembly URL passing verification, the local URL is assembled locally by using the adapted file and the appointed starting parameters, the local URL is used as the starting URL, the starting URL is prevented from being acquired from the device side, the efficiency of acquiring the starting URL is improved, and the speed of starting the media stream is improved after the media stream is started by using the starting URL.
Furthermore, after the client opens the media stream based on the start-up URL, in order to ensure the accuracy of the start-up, the local URL assembled needs to be verified. Optionally, based on the identified start-up parameter, a start-up URL is obtained from the device side. In specific implementation, an ONVIF (Open Network Video Interface Forum ) protocol or an SDK mode can be utilized to combine the identified start-up parameters to obtain the start-up URL from the device side. Illustratively, a request instruction of the getURL is sent to the device based on the ONVIF protocol, where the request instruction includes a start-up parameter to be requested, and the start-up URL is determined according to feedback of the device.
Further, the start-up URL acquired from the device side is compared with the URL assembled locally through S102; if the two are identical, the method indicates that the streaming URL locally generated at the client is accurate; if the two types of files are different, for example, the URL format of the start-up URL obtained from the device side is different from the URL format of the local URL and/or the filling mode of the start-up parameter, it is determined that the adapted file stored locally in the client is inaccurate, and the media stream needs to be restarted according to the start-up URL obtained from the device side, and the adapted file is deleted. Further verification of the adaptation file is thereby achieved.
Fig. 2 is a flowchart of a method for obtaining a start-up URL according to a second embodiment of the present application, where the method is optimized based on the foregoing embodiment, and referring to fig. 2, and the method includes:
s201, after receiving information of successfully logging in the equipment, inquiring whether an adapted file exists locally.
The adaptive file comprises URL formats and a start-up parameter filling mode required by the verified equipment. If there is an adapted file locally, S202 is performed, and if there is no adapted file locally, S203 is performed.
S202, local URL is assembled locally at the client by using the adapted file and the identified start-up parameters, and the local URL is used as the start-up URL so as to start up the media stream based on the start-up URL.
The specific description may be referred to the above embodiments, and will not be repeated here.
S203, if the adapted file does not exist locally, inquiring whether the file to be adapted exists locally.
The file to be adapted comprises a URL format and a start-up parameter filling mode required by unverified equipment; that is, although the file to be adapted includes the URL format and the start-up parameter filling mode required by the device, the accuracy of the start-up URL generated based on the file to be adapted cannot be guaranteed. Thus requiring verification of the file to be adapted.
S204, if the file to be adapted exists, judging whether a current streaming task to be processed exists.
If the file to be adapted exists, entering a state to be adapted, wherein the state to be adapted represents a method for obtaining an unverified assembled URL. When the file to be adapted is verified, whether the client is in a working state at present or not needs to be judged, namely whether a to-be-processed streaming task exists at present or not is judged. If so, S205-S207 are performed, and if not, S208-S209 are performed.
S205, if the to-be-processed start-up task exists, acquiring a start-up URL from the equipment side based on the identified start-up parameter, and starting the media stream by using the start-up URL.
Because the accuracy of the starting URL generated based on the file to be adapted cannot be guaranteed, when the starting task to be processed exists, the starting URL is obtained from the equipment side based on the identified starting parameter, for example, the starting URL can be obtained from the equipment side by utilizing an ONVIF protocol or an SDK mode and combining the identified starting parameter, and then the media stream is started by utilizing the starting URL, so that the starting accuracy is guaranteed.
S206, acquiring a local URL assembled based on the file to be adapted and the identified start-up parameters.
Based on the URL format and parameter filling mode required by the equipment obtained from the file to be adapted, the local URL is assembled locally according to the starting parameters appointed by the user, and the specific assembling process is to supplement the appointed starting parameters to the appointed position of the URL format according to the parameter filling mode.
S207, comparing the start-up URL with the local URL, and processing the file to be adapted according to the comparison result.
And comparing the start-up URL with the local URL, judging whether the start-up URL is the same as the local URL, if so, indicating that the local URL assembled based on the files to be matched is inaccurate, directly deleting the files to be matched, and switching from a state to be matched to an unadapted state, wherein the unadapted state indicates that the method for assembling the URL is not obtained. It should be noted that if the comparison result is the same, multiple judgments may be performed according to the hollow matching operation in S208, and if the comparison result is the same each time, the file to be adapted is rewritten, and the state is switched from the state to be adapted to the adapted state.
S208, if the to-be-processed start-up task does not exist, repeating the idle matching operation according to the preset repetition times.
In the embodiment of the present application, when there is no streaming task, that is, when the client is in an idle state, according to a preset repetition number, idle matching operations are repeatedly executed. The purpose of repeatedly executing the idle matching operation is to verify the file to be adapted. Optionally, the idle matching operation includes: randomly determining a group of start-up parameters, and acquiring a start-up URL from the equipment side based on the start-up parameters; local URL is assembled locally at the client by utilizing the file to be adapted and the streaming parameters; specific generation process can be referred to the description of the above embodiments, and will not be repeated here; and comparing the starting URL with the local URL, and processing the file to be adapted according to the comparison result. .
S209, if the comparison result is the same, the file to be adapted passes verification, is rewritten into an adapted file, and is switched from the state to be adapted to the adapted state.
If the comparison results are the same, the URL generated by the file to be adapted is accurate, namely the file to be adapted is verified, so that the file to be adapted is rewritten into the adapted file, and the state is switched from the state to be adapted to the state to be adapted, so that the current starting URL can be generated locally by the adapted file at the client side, the current starting URL acquisition efficiency is improved, and the current starting speed is improved. It should be noted that if the comparison results are different, deleting the file to be adapted, and switching from the state to be adapted to the state not adapted, wherein the state not adapted indicates that the method of assembling the URL is not obtained.
In the embodiment of the application, if the current starting task exists in the case that only the file to be adapted exists locally, the URL is obtained from the equipment end to finish the current starting, so that the current starting accuracy is ensured. And after the streaming is successful, comparing the local URL generated by the client based on the file to be adapted with the streaming URL acquired from the equipment side to verify the effect of the file to be adapted. If the streaming task does not exist, the idle matching operation is repeatedly executed to verify the effect of generating the local URL based on the file to be adapted.
Fig. 3 is a flowchart of a method for obtaining a start-up URL according to a third embodiment of the present application, where the method is optimized based on the foregoing embodiment, and referring to fig. 3, the method includes:
s301, after receiving information of successfully logging in the equipment, inquiring whether an adapted file exists locally.
The adaptive file comprises URL formats and a start-up parameter filling mode required by the verified equipment. If yes, S302 is executed, and if no, S303 is executed.
S302, the local URL is assembled locally at the client by utilizing the adapted file and the identified streaming parameters, and the local URL is used as the streaming URL so as to open the media stream based on the streaming URL.
S303, if the adapted file does not exist locally, inquiring whether the file to be adapted exists locally.
S304, if the file to be adapted does not exist locally, judging whether a current streaming task to be processed exists.
If the streaming task exists, the slave device acquires the streaming URL of the designated parameter, and starts the media stream through the streaming URL, and the streaming URL and the parameter are reserved after the streaming is successful, so that the data analysis can be performed based on the saved streaming URL and the parameter. If no start-up task exists, S305 is performed.
S305, if no to-be-processed start-up task exists, different start-up URLs are obtained from the equipment side according to the different recognized start-up parameters.
For example, in the case of starting a live stream, if the first identified user designates that the start-up parameters are "1 channel" and "main stream", then a start-up URL including "1 channel" and "main stream" is obtained from the device side; and the second time of identification of the user-specified start-up parameters is 2 channels and main stream, acquiring start-up URLs … … comprising 0 channels and main stream from the equipment side, and so on, and respectively acquiring different start-up URLs from the equipment side according to the identified different start-up parameters. In an alternative embodiment, the different start-up URLs are obtained from locally stored start-up URLs and parameters.
S306, carrying out data analysis on the obtained different start-up URLs, determining whether to find out a method for assembling the URLs according to analysis results, and if so, generating a file to be adapted according to the analysis results.
In an alternative embodiment, the data analysis of the obtained different start-up URLs includes: comparing any two different start-up URLs to determine a fixed field and a variable field; wherein, the fixed field refers to the same field in the two start-up URLs, and the variable field refers to different fields in the two start-up URLs; and determining the corresponding relation between the change field and the start-up parameter.
For example, for the case of opening a live stream, the four-channel and main stream start URL is obtained from the device side: rtsp/192.168.1.64:554/unicast/3/Main/live; the method for acquiring the five-channel and mainstream startup URL from the equipment side comprises the following steps: rtsp/192.168.1.64:554/unicast/4/Main/live; comparing the two start-up URLs, it is known that under the condition of ensuring that the stream number is unchanged, the fixed fields are found to be IP, port numbers (192.168.1.64:554), unicast and live, and the change field is 3,4. From this, four channels are denoted by the numeral "3", five channels are denoted by the numeral "4", and the correlation of the change field and the channel number is: the change field is equal to the channel number minus 1. After the channel number appointed by the user is identified, the value of the change field can be obtained by subtracting 1.
Similarly, keeping the channel number unchanged, obtaining the starting URL of the 4-channel auxiliary stream from the equipment side is as follows: rtsp/192.168.1.64:554/unified/3/Second/live; the method comprises the steps of obtaining a 4-channel and main stream starting URL from the equipment side, wherein the starting URL comprises the following steps: rtsp/(192.168.1.64:554/unicast/3/Main/live). Comparing the two start-up URLs, it can be seen that under the condition of ensuring that the channel number is unchanged, the fixed fields are found to be IP, port numbers (192.168.1.64:554), unicast and live, and the change fields are Second and Main. From this, the relationship between the change field and the stream number is: the Main stream is represented by english Main and the auxiliary stream is represented by english Second. After the stream number appointed by the user is recognized, the stream number is directly expressed by the corresponding English.
Further, for opening the playback stream, similar to the above, referring to the above comparison process, in the case that the channel number and the stream number are determined, the correspondence between the start time and the end time of the change field is determined, for example, expressed in UTC time; as expressed in terms of time of year, month, day, minute, and second; such as expressed in NTP time, etc.
Taking the example of starting a live stream, through the above data analysis, the URL format required by the device may be obtained as follows: rtsp// < IP >: port >/unicast/< channel number >/< stream number >/live; the filling mode of the start-up parameters is as follows: the number corresponding to the channel number is the channel number designated by the user minus 1, and for the stream number, if the designated Main stream is the stream number Main, if the designated auxiliary stream is the stream number Second. Therefore, the file to be adapted can be generated according to the analyzed URL format required by the equipment and the filling mode of the start-up parameters, the file to be adapted can be subsequently verified, the verification process is referred to above, and the file to be adapted is rewritten after the verification is passed, so that the accurate local URL for start-up can be directly generated locally at the client based on the adapted file.
It should be noted that, if the fixed field, the variable field, and the correspondence between the variable field and the start-up parameter are determined according to the analysis result, generating the file to be adapted according to the analysis result includes: and determining a URL format according to the analyzed fixed field and the variation field, and determining a start-up parameter filling mode according to the corresponding relation between the variation field and the start-up parameter, so that a file to be adapted can be generated, namely a method for assembling the local URL is found.
Further, if the method for assembling the URL is not found according to the analysis result, that is, the format of the URL and/or the filling mode of the start-up parameter are not determined, directly performing an unadapted state, where the unadapted state indicates that the method for assembling the URL cannot be found, and then the start-up URL is not acquired from the device side when the media stream needs to be started.
In the embodiment of the application, in the idle state, the data analysis is performed on the acquired open-flow URL, the format of the open-flow URL and the corresponding relation between the change field and the open-flow parameter are determined according to the analysis result, and then the adaptation file is generated, so that the accurate open-flow URL can be generated locally at the client side according to the adaptation file, and the open-flow URL acquisition efficiency is improved.
Fig. 4 is a logic flow diagram of a method for obtaining a start-up URL according to a fourth embodiment of the present application, in which optimization is performed on the basis of the above embodiment, referring to fig. 4, the logic flow of the method for obtaining a start-up URL is as follows:
four states are predefined in this embodiment: the state is adapted, the state is to be adapted, the state is not adapted, and the state cannot be adapted. The adapted state refers to a specific parameter method of self-assembled URL, and is verified to be valid, namely, an adapted file exists locally; the state to be adapted refers to that a specific parameter method for self-assembling the URL is found, and the effect to be verified, namely the file to be adapted exists locally; the unadapted state refers to a specific parameter method for self-assembled URL which is not found yet; the unadapted state refers to multiple attempts to find the assembly method, but cannot be found.
Step 1:
after the client program successfully logs in the equipment, wherein the equipment is optionally NVR equipment, searching for a corresponding adapted file in a local environment, entering an adapted state if the corresponding adapted file is found, and jumping to the step 6; if not, searching a file to be adapted locally, if so, entering a state to be adapted, and jumping to the step 5; if the file to be adapted is not found, the unadapted state is entered, and the step 2 is skipped.
Step 2:
after entering an unadapted state, two conditions exist, if the client has a to-be-processed start-up task, the client is determined to be in a working state, otherwise, the client is determined to be in an idle state. In a working state, acquiring a starting URL of a designated parameter from the equipment side, starting a media stream through the starting URL, and reserving the starting URL and the parameter after the starting is successful; when the client is in an idle state, the streaming URLs of different streaming parameters are acquired from the equipment side, and data analysis is carried out by combining the URL and parameters (if any) of the streaming success before streaming, so as to determine the corresponding relation between the change field in the streaming URL and the streaming parameters and the format of the URL.
Step 3:
if the analysis is successful, namely, the URL format and the corresponding relation between the change field in the URL and the start-up parameter are determined, a file to be adapted is further generated, the state to be analyzed is entered, and the step 5 is skipped. If the URL assembling method cannot be found through analysis, namely the corresponding relation between the change field in the URL and the start-up parameter cannot be determined, and the assembling method cannot be found through multiple times of analysis, entering an unadapted state, namely jumping to the step 4, otherwise returning to a state to be analyzed (namely jumping to the step 2) to continue analysis.
Step 4:
after entering an unadapted state, the client system only acquires the start-up URL from the equipment when the start-up is needed, and the start-up URL of the equipment is not analyzed before logging in the equipment next time.
Step 5:
