According to an embodiment of the present invention, there is provided a recording method of a multimedia device, applied to the computer terminal, and fig. 2 is a flowchart of the recording method of the multimedia device according to the embodiment of the present invention, as shown in fig. 2, including:
step S202, receiving a burning instruction issued by a target platform and used for burning a target event, and establishing a target burning task corresponding to the target event according to the burning instruction;
step S204, determining a burning mode matched with the target burning task in the process of executing the target burning task, wherein the burning mode at least comprises one of the following modes: acquiring the content to be recorded from a memory, and acquiring the content to be recorded from a predetermined video file;
step S206, instructing the multimedia device to burn the content to be burned according to the burning mode matched with the target burning task.
Receiving a burning instruction which is issued by a target platform and used for burning a target event, and establishing a target burning task corresponding to the target event according to the burning instruction; determining a burning mode matched with the target burning task in the process of executing the target burning task, wherein the burning mode at least comprises one of the following modes: acquiring the content to be recorded from a memory, and acquiring the content to be recorded from a predetermined video file; the multimedia device is instructed to burn the content to be burned according to the burning mode matched with the target burning task, namely the content to be burned of the target event is burned according to the target event matching burning mode by establishing the target burning task of the target event.
It should be noted that the size of the code stream is determined according to the number of files of audio and video data generated by the multimedia device; the recording speed is the processing speed of the multimedia equipment for the data to be recorded; the target platform is a task platform that can be used to distribute one or more multimedia devices, which is not limited by the invention.
The foregoing step S204 determines that there are multiple recording modes matching the target recording task, and in an optional embodiment, the following scheme may be implemented: acquiring the recording speed of the multimedia equipment and the current code stream size of the target event; comparing the recording speed with the current code stream to obtain a comparison result; and determining a burning mode matched with the target burning task according to the comparison result.
That is to say, when the multimedia device executes a corresponding target recording task established according to a recording instruction issued by the target platform, the recording of the target event corresponding to the target recording task is executed by selecting a corresponding recording mode according to a comparison result by obtaining the recording speed of the multimedia device and the current code stream size of the data to be recorded generated by the target event and comparing the size relationship between the two.
In an exemplary embodiment, determining the recording mode matching the target recording task according to the comparison result includes: under the condition that the comparison result indicates that the burning speed is larger than the size of the generated current code stream, determining that a burning mode matched with the target burning task is an internal memory burning mode, wherein the internal memory burning mode is used for indicating to obtain the content to be burned from an internal memory; and under the condition that the comparison result indicates that the burning speed is less than or equal to the size of the generated current code stream, determining that the burning mode matched with the target burning task is a video file burning mode, wherein the video file burning mode is used for indicating to acquire the content to be burned from a predetermined video file.
For example, when the recording speed is greater than the size of the generated code stream, a memory recording mode is executed, that is, the content to be recorded is obtained from the memory for recording; when the recording speed is less than or equal to the size of the generated code stream, the recording mode of the video file is selected, namely the content to be recorded is obtained from the predetermined video file for recording, and the two recording modes can be flexibly converted according to the comparison result of the recording speed and the size of the code stream.
Optionally, after the target recording task is executed and a recording mode matched with the target recording task is selected, the method further includes: under the condition that the burning process of the target burning task is abnormal, acquiring the task content of the target burning task with the abnormal burning process; and executing the target burning task with abnormal burning process again according to the task content to recover.
That is to say, an abnormality occurs in the process of recording the target event corresponding to the target recording task, the target event cannot be recorded, at this time, the abnormality can be recorded by the target recording task, meanwhile, some operation instructions for the multimedia device in the process of recording the target event can be recorded by the target recording task and executed, and further, the target event with the abnormality can be recovered by the target recording task.
Optionally, after determining a burning mode matched with the target burning task in the process of executing the target burning task, the method further includes: under the condition that the recording mode is determined to be that the content to be recorded is obtained from the memory, obtaining a recording time period corresponding to the target recording task; under the condition that the content to be recorded corresponding to the recording time period is located in the memory, directly obtaining the content to be recorded from the memory for recording; and under the condition that the content to be recorded corresponding to the recording time period is not located in the memory, acquiring a video file corresponding to the recording time period, and recording according to the video file.
That is, after matching the recording mode for the target event according to the target recording task, when it is determined that the target event needs to execute the recording mode for obtaining the content to be recorded from the memory, the recording time period of the target event is determined according to the target recording task, and then the start-stop time for recording the target event can be obtained.
Optionally, after determining a burning mode matched with the target burning task in the process of executing the target burning task, the method further includes: reading a first video file from a plurality of video files for recording under the condition that the recording mode is determined to be the condition of acquiring the content to be recorded from the predetermined video file; and determining whether the time of the last frame of data of the first video file is in the plurality of video files, and selecting a second video file corresponding to the time of the last frame of data to continue burning under the condition that the time of the last frame of data is in the plurality of video files.
That is, when the recording mode of the target event is determined according to the target recording task, the content to be recorded is obtained from the predetermined video file for recording, the first video file which is used as the initial recording is obtained from the plurality of video files existing in the video file for recording, and in order to ensure that the video files can be well continuous after recording, after the recording of the first video file is completed, the position information of the time of the last frame data of the first video file at the position of the plurality of video files is judged, the second video file corresponding to the time is selected for recording, and the continuity of the recorded files is further ensured.
Optionally, after the target recording task of the target event is established according to the recording command, the method further includes: judging whether a target recording instruction of the optical disc exists in the received recording instruction, wherein the target recording instruction is used for indicating that the identification information corresponding to the target recording task is recorded at the target position of the optical disc; and recording the identification information at the target position of the optical disc in response to the target recording instruction.
In short, in order to make the optical disc recording the target event easier to be identified, the recording instruction issued by the target platform may further include information for recording the identification information corresponding to the target recording task at the target position of the optical disc, and further, when the target event is recorded by the multimedia device, the identification information related to the target event is recorded at the target position on the optical disc which is convenient to be identified.
The following explains the flow of the recording method of the multimedia device with reference to several alternative embodiments, but is not intended to limit the technical solution of the embodiments of the present invention.
An alternative embodiment of the present invention provides a recording fault-tolerant system for an interrogation device, and fig. 3 is a schematic diagram of a recording fault-tolerant system for an interrogation device according to an alternative embodiment of the present invention, including: a video storage module 32, a memory cache module 34, a recording module 36, and a management platform 38.
The video storage module 32: the system is used for storing audio and video data generated by an audition hard disk video recorder device or a front-end monitoring camera (which is equivalent to the multimedia device in the embodiment of the invention); for each recording task (corresponding to the target recording task in the embodiment of the present invention), other commands related to the operation related to the current recording of the optical disc are also recorded in the record.
Optionally, the recording of the recording task may include command information of recording case-related information content on the cover of the optical disc.
The memory cache module 34: the method is used for caching audio and video data generated by the trial video recorder equipment or the front-end monitoring camera for a certain time (such as 30s) in the memory. The memory cache only caches the audio and video data at a certain time recently.
It should be noted that the buffering time may be set according to the actual needs of the user, which is not limited in this embodiment of the present invention.
The recording module 36: the method is used for recording the audio and video data generated by the trial video recorder equipment or the front-end monitoring camera on the optical disk.
Management platform 38 (equivalent to the target platform in the present embodiment): and the platform is used for carrying out unified scheduling management on the trial video recorder equipment or the front-end monitoring camera.
In an optional embodiment of the present invention, when the centralized recording is not adopted, the video storage module 32, the memory cache module 34, and the recording module 36 may be inside the same interrogation hard disk recorder device; when the centralized recording is adopted, the recording storage module 32 may be inside the trial hard disk recorder device, and the memory cache module 34 and the recording module 36 may be inside the centralized recording cabinet. The recording module 36 and the video storage module 32 can communicate (e.g., network communication), so as to realize information interaction between the recording module 36 and the video storage module 32, so as to report recording abnormality occurring in the recording task, query recording conditions of the video file, acquire information generated by transmitting video data and sending a signal to prompt the video file to be packaged as soon as possible, and the like.
An alternative embodiment of the present invention further provides a recording fault-tolerant method for an interrogation device, as shown in fig. 4, the specific steps are as follows:
firstly, a platform issues a burning command to an interrogation hard disk video recorder device;
step two, trial video recorder equipment establishes records including the start and stop time of recording for the recording task;
when the platform issues other commands related to the recording operation, the commands related to the recording operation are also recorded into the recording task, such as a command for recording the related information content of the record on the cover of the optical disc.
Thirdly, judging the size of the generated code stream and the recording speed by the trial video recorder equipment, and determining a default recording mode;
when the recording speed is larger than the generated code stream size, a memory recording mode is adopted by default, and code stream data is acquired from a memory cache module by default for recording; when the recording speed is less than or equal to the size of the generated code stream, a video file recording mode is adopted by default, and then code stream data is continuously acquired from the video file generated by packaging for recording, so that the stability of data recording is ensured; that is, under the condition of using the video file recording mode, when the size of the code stream is lower than the recording speed, since the data of the code stream is generated too fast, if the video file recording mode is switched to the internal memory recording mode, the situation that the recording is not in time may occur, and then the video file recording mode is switched back, therefore, in order to ensure the stability of the data recording and facilitate the management, the video file recording mode is continuously maintained.
It should be noted that, considering the security of the trial video file, the video file generated by the trial hard disk recorder device is often generated after a certain delay, which is not limited by the optional embodiment of the present invention.
And step four, judging that the recording mode is the internal memory recording mode by the trial video recorder equipment, and directly starting to fetch the audio and video data for recording from the corresponding initial time in the internal memory buffer module within the data of the internal memory buffer module at the recording time. If the recording time is not in the data of the memory buffer module, the recording file with the corresponding time needs to be inquired or waited for being generated by packaging, and the audio and video data is read from the packaged file for recording. And after reading a file, comparing the time of the last frame of video data, judging whether the time is in the data of the memory buffer module, and if so, switching to obtain the audio and video data from the memory buffer module for recording.
