The first application and the second application are respectively corresponding to memory spaces for storing the first multimedia data, and the memory space for storing the first multimedia data by the first application or the memory space for storing the first multimedia data by the second application is set as a shared memory space, so that one or more third applications can access the shared memory space to acquire the first multimedia data. Therefore, the existing memory space for storing the first multimedia data is set as the shared storage space, the need of additionally opening up a storage space as the shared storage space is avoided, and the space resources occupied by the multimedia data can be saved.
As an embodiment of the present invention, each invocation request carries a corresponding acquisition parameter, as shown in fig. 4, after S103, the method may further include:
in S401, after it is monitored that the first application calls the multimedia data acquisition device, the multimedia data acquisition device is called according to the acquisition parameter carried in the second call request to acquire multimedia data, and the acquired second multimedia data is sent to the second application.
In the present embodiment, the acquisition parameters may include, but are not limited to, one or more of acquisition frequency, data format, and data capacity of the multimedia data. The calling mode of the application to the multimedia data acquisition device can comprise a main mode and a secondary mode. The multimedia data acquisition device acquires data according to acquisition parameters corresponding to the application called in the primary mode, the application called in the secondary mode can only receive the multimedia data acquired by the multimedia data acquisition device, and the corresponding acquisition parameters cannot be used for indicating the acquisition of the multimedia data.
In S103, the first application calls the multimedia data acquisition device in the active mode, so that the multimedia data acquisition device acquires the first multimedia data according to the acquisition parameters carried in the first call request, and the first application may control the acquisition of the multimedia data by changing the acquisition parameters, such as changing the acquisition frequency and changing the data format. The second application calls the multimedia data acquisition device in a secondary mode, only the first multimedia data acquired by the multimedia data acquisition device can be acquired, and the second application cannot control the acquisition of the multimedia data in a mode of changing acquisition parameters.
The end of the calling of the multimedia data acquisition device by the first application can be monitored by acquiring a calling end message sent by the first application. If the calling of the multimedia data acquisition device by the first application is monitored to be finished, the calling of the multimedia data acquisition device by the first application is indicated to be finished, at the moment, the auxiliary mode of the second application can be switched to the main mode, and the multimedia data acquisition device acquires the second multimedia data according to the acquisition parameters carried by the second calling request.
In this embodiment, after the first application finishes the call of the multimedia data acquisition device, the second application calls the multimedia data acquisition device in the active mode, so that the second application can control the acquisition of the multimedia data by changing the acquisition parameters according to the own requirements.
As an embodiment of the present invention, as shown in fig. 5, after S401, the method may further include:
in S501, when the second application calls the multimedia data acquisition device, if a fourth call request sent by the first application is received, the multimedia data acquisition device is called according to an acquisition parameter carried in the fourth call request to acquire multimedia data, and the acquired third multimedia data is sent to the first application and the second application, respectively.
In this embodiment, during the period when the second application calls the multimedia data acquisition device in the active mode to perform data acquisition, if a call request sent by the first application is received, it indicates that the first application needs to call the multimedia data acquisition device again, the active mode of the second application may be switched back to the secondary mode, so that the first application calls the multimedia data acquisition device in the active mode again, the multimedia data acquisition device performs data acquisition according to the acquisition parameters carried by the fourth call request, and the acquired third multimedia data is sent to the first application and the second application respectively. Therefore, the first application can still control the collection of the multimedia data by changing the collection parameters according to the self requirement when the multimedia data collection is carried out again.
As an embodiment of the present invention, as shown in fig. 6, the "sending the first multimedia data to the first application and the second application, respectively" in S103 may include:
in S601, a first call priority of the first application to the multimedia data acquisition device and a second call priority of the second application to the multimedia data acquisition device are obtained.
In this embodiment, for one multimedia data acquisition apparatus, each application has a corresponding call priority. When a plurality of applications call the multimedia data acquisition device at the same time, the multimedia data acquisition device acquires data according to the acquisition parameters of the application with the highest calling priority, and other applications can only acquire the acquired multimedia data and cannot control the acquisition of the multimedia data.
In S602, the first call priority and the second call priority are compared.
In S603, if the first call priority is higher than the second call priority, the first multimedia data is respectively sent to the first application and the second application.
In this embodiment, when the first call priority is higher than the second call priority, the multimedia data acquisition device needs to perform data acquisition according to the acquisition parameter corresponding to the first application, and since the multimedia data acquisition device performs data acquisition according to the acquisition parameter carried in the first call request in S102, the multimedia data acquisition device does not need to be changed, and the first multimedia data can be directly and respectively sent to the first application and the second application.
In S604, if the first call priority is lower than the second call priority, the multimedia data acquisition device is called according to the second call request to acquire multimedia data, and the acquired fourth multimedia data is respectively sent to the first application and the second application.
In this embodiment, when the first call priority is lower than the second call priority, the multimedia data acquisition device needs to perform data acquisition according to the acquisition parameters corresponding to the second application, so that the multimedia data acquisition device can perform data acquisition according to the acquisition parameters carried in the second call request, and send the acquired fourth multimedia data to the first application and the second application respectively.
In this embodiment, each application is provided with a corresponding call priority, and when a plurality of applications call the multimedia data acquisition device at the same time, the multimedia data acquisition device performs data acquisition according to acquisition parameters corresponding to the application with the highest call priority by comparing the call priorities of the applications, so that the acquired multimedia data can meet the requirements of the application with the highest call priority.
As an embodiment of the present invention, as shown in fig. 7, the sending the collected fourth multimedia data to the first application in S604 may include:
in S701, it is determined whether the fourth multimedia data conforms to a data format required to be acquired by the first application.
In S702, if the fourth multimedia data does not conform to the data format required to be acquired by the first application, the fourth multimedia data is resampled.
In S703, the resampled fourth multimedia data is sent to the first application.
In this embodiment, the fourth multimedia data is data acquired by the multimedia data acquisition device according to the acquisition parameters carried by the second invocation request, so that the fourth multimedia data conforms to the data format required to be acquired by the second application, but the data format required to be acquired by the second application and the first application may be different, and therefore, whether the first multimedia data conforms to the data format required to be acquired by the first application or not can be determined.
If the fourth multimedia data conforms to the data format required to be acquired by the first application, the fourth multimedia data can be used by the first application, and therefore the fourth multimedia data is directly sent to the first application; if the fourth multimedia data does not conform to the data format required to be acquired by the first application, it is indicated that the first application cannot directly use the fourth multimedia data, so that the fourth multimedia data is resampled, the data format of the resampled fourth multimedia data conforms to the data format required to be acquired by the first application, and the resampled fourth multimedia data can be used by the first application.
According to the method and the device, the fourth multimedia data which do not conform to the data format required to be acquired by the first application are resampled, so that the resampled fourth multimedia data can conform to the requirement of the first application, the situation that the fourth multimedia data cannot be used by the first application due to the data format problem is avoided, and the multimedia data can be used by the first application and the second application at the same time.
Fig. 8 shows an implementation example provided by the embodiment of the present invention. The X application program and the Y application program call the cameras to acquire images, the X application program calls the cameras in a primary mode, and the Y application program calls the cameras in a secondary mode. And the camera acquires images according to acquisition parameters corresponding to the X application program and respectively sends the acquired images to a buffer register corresponding to the X application program and a buffer register corresponding to the Y application program. The image data acquired by the X application and the Y application are identical. When the X application program quits using the camera, the Y application program can synchronously receive the message, quit the secondary mode and change to using the camera in the primary mode. When the X application program reuses the camera, the Y application program can also synchronously receive the message and exit the main mode, at the moment, the X application program can continue to use the camera in the main mode, and the B application program is converted into the auxiliary mode. The above embodiment is only used for explaining the multimedia data sharing method, and is not limited, for example, the X application and the Y application may also call the multimedia data acquisition device to acquire multimedia data such as audio and video.
Fig. 9 shows another implementation example provided by the embodiment of the present invention. The memory space for storing the images by the Y application is set as the shared memory space, and the Y1 application, the Y2 application, the Y3 application and the like can access the shared memory space to acquire the images acquired by the camera.
