Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments based on the embodiments in the present invention, which can be made by those skilled in the art in light of the present disclosure, are within the scope of the present invention.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
With the development of science and technology, more and more functions can be realized by terminal equipment such as smart phones, tablets and the like, from call receiving and making, internet surfing to photographing, video recording, video call and the like; more and more cameras or microphones can be used, and users can select applications to record audio and video, take pictures or carry out video calls and the like according to own requirements.
For a terminal device with a camera and a microphone, the camera and the microphone are exclusive resources, and when an application wants to use the camera or the microphone, the application needs to use the camera or the microphone through an interface of the terminal device. When other applications want to use the camera or the microphone at the same time, only the application with the highest priority or the application calling the interface of the camera or the microphone last can use the camera or the microphone. Therefore, the existing method using a camera or a microphone only supports one application for using data collected by the camera or the microphone, and there is no scheme for simultaneously using data collected by the camera or the microphone for two or more applications in one terminal device.
For example, fig. 1a is a schematic diagram of using a camera or a microphone by an existing Application according to the present invention, as shown in fig. 1a, when an Application a uses the camera or the microphone, an Application Programming Interface (API) of the camera or the microphone is called, and if an Application B also wants to use the camera or the microphone at this time, only an Application with a higher priority or calling the API at last can acquire the usage right of the camera or the microphone.
In view of the problems in the prior art, the inventor finds that, in the process of researching a method for sharing media data by multiple applications, data acquired by two or more applications simultaneously using a camera or a microphone in one terminal device can be realized in a media data sharing manner among the multiple applications. The method comprises the steps that a main control application and a sharing application are configured, the sharing application sends query information to the main control application, the parameter range of media data which can be provided by the main control application is obtained through the query information, and if the recording parameters of the media data required by the sharing application are met, a media data acquisition request is further sent to the main control application. After receiving the media data acquisition request, the master control application calls an interface of the media equipment of the terminal equipment to record the media data, encodes the obtained original media data according to the recording parameters in the media data acquisition request, and sends the encoded original media data to the shared application through a local port corresponding to the port identifier in the media data acquisition request. Based on the inventive concept, the scheme of sharing media data by multiple applications in the invention is designed.
Fig. 1b is a schematic view of a scenario of a method for sharing media data by multiple applications according to the present invention, and as shown in fig. 1b, the scenario of the application may include: a terminal device 11, a master application 12, and at least one shared application (fig. 1b shows two shared applications, namely a shared application 13 and a shared application 14).
The terminal equipment adopted by the scheme is equipment which is provided with a camera and/or a microphone, can run corresponding applications and can perform data processing and data transmission between the applications, and the terminal equipment comprises but is not limited to a smart phone, a tablet personal computer and a computer.
For example, in the application scenario shown in fig. 1b, the terminal device 11 is a smartphone of an android system, and when a user wants to perform multiple applications and use a camera or a microphone at the same time, the shared application 13 is opened, the shared application 13 sends query information to the master control application 12, and then the master control application 12 returns a parameter range of media data that can be provided by the master control application to the shared application 13. When the recording parameter of the media data required by the sharing application 13 is within the parameter range of the media data that can be provided by the main control application, the sharing application 13 sends a media data acquisition request to the main control application 12, and then the main control application 12 sends the target media data to the sharing application 13 according to the media data acquisition request, and the sharing application 13 receives the target media data.
Correspondingly, after receiving the query information sent by the sharing application 13, the main control application 12 obtains the parameter range of the media data supported by the terminal device 11, and after obtaining the parameter range of the media data that can be provided by the main control application, sends the parameter range of the media data to the sharing application 13. After receiving the media data acquisition request sent by the sharing application 13, the main control application 12 calls an interface of the media device of the terminal device 11 to record media data, acquires original media data, codes the original data according to recording parameters in the media data acquisition request, and finally sends the original data to the sharing application 13.
It should be noted that fig. 1b is only a schematic diagram of an application scenario provided in the embodiment of the present invention, and the embodiment of the present invention does not limit the actual form of the terminal device included in fig. 1b, nor limit the forms of the master control application and the shared application, where the master control application and the shared application are in the form of an application program in a smart phone or a tablet, and are in the form of software in a computer, and in the specific application of the scheme, the setting may be performed according to actual requirements.
The technical solution of the present invention will be described in detail below with reference to specific examples. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Before the method for sharing media data by multiple applications provided by the present invention is performed, a master application and a sharing application need to be configured in a terminal device, the master application is configured as an application for operating an interface of a media device, and the sharing application is configured as an application that needs to share media data. The main control application can directly operate the media device through the interface of the media device to obtain the media data. The shared application needs to send a media data acquisition request to the shared application when acquiring the media data, and the media data is acquired by the master control application and then sent to the shared application.
It should be noted that the media data includes audio data, video data, and audio-video data.
Fig. 2 is a flowchart illustrating a first embodiment of a method for sharing media data among multiple applications, as shown in fig. 2, the method for sharing media data among multiple applications specifically includes the following steps:
s201: and responding to the media data recording operation of the user on any sharing application, and sending a media data acquisition request to the master control application by the sharing application.
When a user wants to use a sharing application to realize services such as video shooting, audio recording or video call, the user clicks a button on a graphical user interface of a terminal device, and the sharing application needs to judge whether recording parameters of media data required by the sharing application are within a parameter range of the media data provided by a main control application. And if the required recording parameters of the media data are in the range of the parameters of the media data available by the master control application, the sharing application sends a media data acquisition request to the master control application. And if the required recording parameters of the media data are not in the parameter range of the media data provided by the master control application, displaying prompt information on a graphical user interface of the terminal equipment for prompting a user that the media data of the current camera or microphone do not meet the service requirements.
In this step, when the sharing application determines that the recording parameter of the required media data is within the parameter range of the media data that can be provided by the master control application, the sharing application sends a media data acquisition request to the master control application, where the media data acquisition request includes the port identifier and the recording parameter. The subsequent main control application can perform coding processing on the original media data according to the recording parameters, and then send the processed target media data to the shared application through the local port corresponding to the port identifier.
For example, the recording parameter in the media data acquisition request may be a resolution, a sampling rate, and a value corresponding to the resolution and the sampling rate, and may also be a frame rate, a sampling depth, and a value corresponding to the frame rate and the sampling depth. The embodiment of the invention does not specifically limit the recording parameters and the size of the recording parameters in the media data acquisition request, and can select the recording parameters according to the actual situation.
S202: and the master control application calls an interface of the media equipment of the terminal equipment to record the media data according to the media data acquisition request so as to acquire the original media data.
In this step, after the sharing application sends a media data acquisition request to the master control application, the master control application receives the request, and then calls an interface of the media device of the terminal device to record media data, so as to acquire original media data. And the master control application determines whether the master control application needs to use the original media data, and if the master control application needs to use the original media data, the master control application copies the original media data locally.
Illustratively, if a user wants to record audio and video through the shared application, the master control application calls APIs corresponding to the camera and the microphone to obtain media data of the audio and video.
Illustratively, a user uses a master control application to record audio and video, and wants to use a shared application to perform video call, the master control application copies original media data after acquiring the original media data, uses one master control application, processes one master control application and sends the master control application to the shared application.
S203: and the master control application sends the required target media data to the shared application according to the original media data, the port identification and the recording parameter in the media data acquisition request, wherein the target media data is obtained by encoding the original media data.
In this step, after the master control application acquires the original media data, the media data is encoded according to the recording parameters in the media data acquisition request, so as to obtain the target media data. And then finding a corresponding local port of the terminal equipment system according to the port identification in the media data acquisition request, and sending the target media data to the shared application through the local port.
In the method for sharing media data by multiple applications provided by this embodiment, a media data acquisition request is sent to a master control application by a sharing application, and the master control application directly calls an interface of a media device after receiving the media data acquisition request, so as to obtain original media data. The main control application encodes the original media data according to the recording parameters in the media data acquisition request and then sends the original media data to the shared application through the local port, so that the data acquired by two or more applications in one terminal device simultaneously using a camera or a microphone is realized.
Fig. 3 is a flowchart illustrating a second embodiment of a method for sharing media data by multiple applications, as shown in fig. 3, in this embodiment, the step S203 may be implemented by the following steps:
s301: and the main control application carries out coding processing on the original media data according to the recording parameters to obtain target media data.
In this step, after the master control application acquires the original media data, the original media data is encoded according to the recording parameters in the media data acquisition request, so that the original media data meets the requirements of the recording parameters, and the encoded original media data is used as target media data.
Illustratively, the recording parameter is 1280ppi by 720ppi resolution and 44.1KHz sampling rate, and then the main control application encodes the original media data into target media data with 1280ppi by 720ppi resolution and 44KHz sampling rate.
Optionally, S302: and the master control application compresses the target media data to obtain the compressed target media data.
In this step, after the master control application obtains the target media data, it may also select to perform compression processing on the target media data, so as to obtain the compressed target media data. The target media data is compressed, so that the storage space occupied by the target media data is reduced, and the transmission speed is increased.
It should be noted that, the case of selecting to perform compression processing on the target media data may be: when the working personnel configure the master control application, the preset space threshold value is set in the master control application, and after the master control application acquires the target media data, if the storage space occupied by the target media data exceeds the preset space threshold value, the target media data is compressed. The case of selecting the compression processing on the target media data may also be: and after the main control application acquires the target media data, directly compressing the target media data. The embodiment of the invention does not limit the condition of selecting to compress the target media data, does not limit the preset space threshold, and can select and set according to the actual condition.
S303: and the master control application sends the target media data to the shared application through the local port corresponding to the port identification.
In this step, after the master control application acquires the target media data, the local port in the corresponding terminal device system is found through the port identifier in the media data acquisition request, and the target media data is sent to the shared application through the local port.
Optionally, if the master control application performs compression processing on the target media data after acquiring the target media data, the compressed target media data is sent to the shared application through the local port.
In the method for sharing media data by multiple applications provided by this embodiment, the primary media data is encoded by the master control application, and the target media data is obtained and then transmitted to the sharing application. The master control application can also select to compress the target media data, and the compressed target media data is transmitted to the sharing application. The data collected by the camera or the microphone can be used by two or more applications in one terminal device, and the data transmission efficiency is improved.
Fig. 4 is a flowchart illustrating a third embodiment of a method for sharing media data by multiple applications, as shown in fig. 4, on the basis of the foregoing embodiment, before a sharing application sends a media data acquisition request to a master control application, the method for sharing media data by multiple applications further includes the following steps:
s401: the sharing application sends query information to the master application.
Since it is necessary to determine whether the recording parameter of the media data required by the sharing application is within the parameter range of the media data that can be provided by the master control application before the sharing application sends the media data acquisition request to the master control application, the sharing application also needs to acquire the parameter range of the media data that can be provided by the master control application before sending the media data acquisition request to the master control application.
In this step, the sharing application sends query information to the master control application, where the query information is used to query a parameter range of media data that can be provided by the master control application.
It should be noted that the trigger event for the shared application to send the query information to the master application may be: the user wants to use the sharing application to realize services such as video shooting, audio recording or video call, and clicks a button on a graphical user interface of the terminal device. The trigger event for the shared application to send the query information to the master application may also be: after the master control application and the shared application are configured, the shared application is started for the first time. The embodiment of the invention does not limit the trigger event of sending the query information to the master control application by the shared application, and can select the trigger event according to the actual situation.
S402: and the master control application acquires the parameter range of the media data supported by the terminal equipment according to the query information.
In this step, after the shared application sends the query information to the master control application, the master control application receives the query information, and then the parameter range of the media data supported by the terminal device can be directly obtained.
Illustratively, the parameter ranges of the media data supported by the terminal device include: the resolution ranges from 630ppi 360ppi to 3840ppi 2160ppi, the frame rate ranges from 10fps to 120fps, the sampling depth ranges from 16Bit to 24Bit, and the sampling rate ranges from 44.1KHz to 48 KHz. The embodiment of the invention does not limit the parameters and parameter ranges of the media data supported by the terminal equipment and can select the parameters according to the actual situation.
S403: the master control application obtains the parameter range of the media data which can be provided by the master control application according to the parameter range of the media data supported by the terminal equipment.
In this step, after the master control application obtains the parameter range of the media data supported by the terminal device, or a subset of the parameter range of the media data supported by the terminal device, is determined as the parameter range of the media data that can be provided by the master control application.
For example, the manner for the master application to obtain the parameter range of the media data that can be provided by the master application may be as follows: after the master control application obtains the parameter range of the media data supported by the terminal equipment, the number of the shared applications for sharing the media data at the moment is obtained, and the parameter range of the media data provided by the master control application is determined according to the number of the shared applications. The method comprises the steps of setting a mapping relation between the number and the proportion of shared applications for sharing media data in a master control application, finding out the corresponding proportion according to the number, and selecting the range of the proportion from the parameter range of the media data supported by the terminal equipment as the parameter range of the media data provided by the master control application. Exemplarily, the number of shared applications for sharing media data is 0, the corresponding proportion is 100%, and the parameter range of the media data supported by the terminal device is used as the parameter range of the media data provided by the master control application; the number of sharing applications for sharing the media data is 3, the corresponding proportion is 50%, and the first 50% of the parameter range of the media data supported by the terminal device is used as the parameter range of the media data provided by the master control application.
For example, the manner for the master application to obtain the parameter range of the media data that can be provided by the master application may also be: the master control application provides the same parameter range of the media data which can be provided by the master control application for each shared application according to the number of the shared applications in the terminal equipment. The main control application is provided with a mapping relation between the number and the proportion of the shared applications, the corresponding proportion is found according to the number, and the range of the proportion is selected from the parameter range of the media data supported by the terminal equipment and is used as the parameter range of the media data provided by the main control application. Exemplarily, the number of shared applications in the terminal device is 1, the corresponding proportion is 100%, and the parameter range of the media data supported by the terminal device is used as the parameter range of the media data provided by the master control application; the number of the shared applications in the terminal device is 5, the corresponding proportion is 50%, and the first 50% of the parameter range of the media data supported by the terminal device is used as the parameter range of the media data provided by the master control application.
