Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which are made by a person skilled in the art based on the embodiments of the invention in light of the present disclosure, are intended to be within the scope of the invention.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise 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, the terminal devices such as smart phones and tablets can realize more and more functions, from call answering, internet surfing, photographing, video recording, video call and the like; more and more applications can use cameras or microphones on terminal devices, and users can select applications to record audio and video, photograph or communicate video 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 by calling an interface of the camera or the microphone of the terminal device. When other applications want to use the camera or microphone at the same time, only the application with the highest priority or the application that finally calls the interface of the camera or microphone can use the camera or microphone. Therefore, the existing method of using the camera or the microphone only supports one application to use the data collected by the camera or the microphone, and no scheme for simultaneously using the data collected by the camera or the microphone by two or more applications in one terminal device exists at present.
For example, fig. 1a is a schematic diagram of a camera or a microphone used by an existing application provided by the present invention, as shown in fig. 1a, when the camera or the microphone is used by an application a, an application programming interface (Application Programming Interface, abbreviated as API) of the camera or the microphone is called, if the camera or the microphone is also wanted to be used by an application B at this time, only an application with a higher priority or an application calling the API last can obtain the use permission of the camera or the microphone.
In order to solve the problems in the prior art, the inventor finds that in the process of researching a method for sharing media data by multiple applications, the data acquired by two or more applications by using cameras or microphones in one terminal device can be realized by sharing the media data among the multiple applications. Firstly, configuring a master control application and a sharing application, wherein the sharing application sends query information to the master control application, and sends a media data acquisition request to the master control application if the parameter range of media data which can be provided by the master control application and obtained through the query information meets the recording parameters of the media data required by the sharing application. After receiving the media data acquisition request, the master control application calls an interface of media equipment of the terminal equipment to record the media data, and the obtained original media data is encoded according to recording parameters in the media data acquisition request and is sent to the sharing application through a local port corresponding to a port identifier in the media data acquisition request. Based on the inventive concept, a scheme for 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, as shown in fig. 1b, where the application scenario may include: terminal device 11, master application 12, at least one sharing application (fig. 1b shows two sharing applications, sharing application 13, sharing application 14, respectively).
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 inter-application data transmission, and comprises but not limited to a smart phone, a tablet personal computer and a computer.
In the application scenario shown in fig. 1b, the terminal device 11 is an android system smart phone, and when a user wants to use a camera or a microphone while performing multiple applications, the shared application 13 is opened, and the shared application 13 sends query information to the master application 12, so that the master application 12 returns the parameter range of the media data available by the master application to the shared application 13. When the recording parameters of the media data required by the sharing application 13 are within the parameter range of the media data available to the master application, the sharing application 13 sends a media data acquisition request to the master application 12, and then the master 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.
Accordingly, after receiving the query information sent by the sharing application 13, the master control application 12 obtains the parameter range of the media data supported by the terminal device 11, and sends the parameter range of the media data available to the master control application to the sharing application 13. After receiving the media data acquisition request sent by the sharing application 13, the master control application 12 calls an interface of the media device of the terminal device 11 to record media data, acquires original media data, encodes 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 by the embodiment of the present invention, the embodiment of the present invention does not limit the actual form of the terminal device included in fig. 1b, and also does not limit the forms of the master control application and the sharing application, where the forms of the master control application and the sharing application in the smart phone or the tablet are application programs, the forms of the master control application and the sharing application in the computer are software, and in the specific application of the scheme, the master control application and the sharing application can be set according to the actual requirements.
The technical scheme of the invention is described in detail through specific embodiments. It should be noted that the following 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 invention is carried out, a master control application and a sharing application are required to be configured in the terminal equipment, the master control application is configured as an application for operating an interface of the media equipment, and the sharing application is configured as an application for carrying out media data sharing. The master 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, and the master control application acquires the media data and then sends the acquired media data to the shared application.
The media data includes audio data, video data, and audio-video data.
Fig. 2 is a flowchart of a first embodiment of a method for sharing media data by multiple applications, as shown in fig. 2, where the method for sharing media data by 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 the sharing application to realize the services of shooting video, recording audio or carrying out video call, the user clicks a button on a graphical user interface of the terminal device, and the sharing application needs to judge whether recording parameters of media data needed by the sharing application are within the parameter range of the media data available by the main control application. If the recording parameters of the needed media data are within the parameter range of the media data which can be provided by the master control application, the sharing application sends a media data acquisition request to the master control application. If the recording parameters of the needed media data are not in the parameter range of the media data which can be provided by the main control application, a prompt message is displayed on a graphical user interface of the terminal equipment, and the prompt message is used for prompting the user that the media data of the current camera or microphone do not meet the service requirement.
In this step, when the sharing application determines that the recording parameters of the required media data are within the parameter range of the media data available to the master application, the sharing application sends a media data acquisition request to the master application, where the media data acquisition request includes the port identifier and the recording parameters. The subsequent master control application can encode the original media data according to the recording parameters, and then the processed target media data is sent to the sharing application through the local port corresponding to the port identification.
The recording parameters in the media data acquisition request may be, for example, resolution, sampling rate, and values corresponding to the resolution and the sampling rate, and may also be, for example, frame rate, sampling depth, and values corresponding to the frame rate and the sampling depth. The embodiment of the invention does not specifically limit the recording parameters and the sizes of the recording parameters in the media data acquisition request, and can be selected according to actual conditions.
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, and acquires 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 media data acquisition request, and then invokes an interface of a media device of the terminal device to record the media data, so as to acquire original media data. The master control application determines whether the master control application needs to use the original media data or not, and if the master control application needs to use the original media data, the master control application copies the original media data locally.
For example, if the user wants to record the audio and video through the sharing application, the main control application may call the APIs corresponding to the camera and the microphone to acquire the media data of the audio and video.
For example, when the user uses the master control application to record audio and video and also wants to use the sharing application to perform video call, the master control application copies the original media data after obtaining the original media data, uses one master control application, processes one master control application and sends one master control application to the sharing application.
S203: the main control application sends the target media data needed by the main control application to the sharing application according to the original media data, the port identification and the recording parameter in the media data acquisition request, and the target media data is obtained by encoding the original media data.
In this step, after the master control application obtains the original media data, the media data is encoded according to the recording parameters in the media data obtaining request, so as to obtain the target media data. And then, according to the port identification in the media data acquisition request, a local port of the corresponding terminal equipment system is found, and then the target media data is sent to the sharing application through the local port.
According to the method for sharing media data by multiple applications, the media data acquisition request is sent to the master control application through the sharing application, and the master control application directly calls the interface of the media device after receiving the media data acquisition request to obtain the original media data. The master 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 sharing application through the local port, so that the data acquired by two or more applications in one terminal device by using cameras or microphones at the same time is realized.
Fig. 3 is a flow chart of a second embodiment of a method for sharing media data by multiple applications provided by the present invention, as shown in fig. 3, in this embodiment, the step S203 may be implemented by:
s301: and the main control application encodes the original media data according to the recording parameters to obtain target media data.
In this step, after the master control application obtains the original media data, the master control application encodes the original media data according to the recording parameters in the media data obtaining 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.
For example, the recording parameter is 1280ppi×720ppi, and the sampling rate is 44.1KHz, and then the master application encodes the original media data into target media data with a resolution of 1280ppi×720ppi and a sampling rate of 44KHz after obtaining the original media data.
Optionally, S302: and the main control application compresses the target media data to obtain the compressed target media data.
In this step, after the main control application obtains the target media data, the main control application may further selectively compress the target media data to obtain the compressed target media data. The compression processing of the target media data can reduce the storage space occupied by the target media data and accelerate the transmission speed.
It should be noted that, the case of selecting to compress the target media data may be: when a worker configures a main control application, a preset space threshold is set in the main control application, and after the main control application acquires target media data, if the main control application judges that the occupied storage space of the target media data exceeds the preset space threshold, the target media data is compressed. The case of selecting to compress the target media data may also be: after the target media data is obtained, the main control application directly compresses the target media data. The embodiment of the invention does not limit the condition of selecting to compress the target media data or limit the preset space threshold value, and can be selected and set according to the actual condition.
S303: the master control application sends the target media data to the sharing application through the local port corresponding to the port identification.
In this step, after the master control application obtains the target media data, the local port in the corresponding terminal device system is found through the port identifier in the media data obtaining request, and the target media data is sent to the sharing application through the local port.
Optionally, if the master control application compresses the target media data after obtaining the target media data, the target media data after the compression is sent to the sharing application through the local port.
According to the method for sharing media data by multiple applications, the primary media data is encoded by the master control application, and the target media data is obtained and then sent to the sharing application. The main control application can also select to compress the target media data, and the compressed target media data is generated to the sharing application. The method and the device realize that two or more applications in one terminal device use the data collected by the camera or the microphone at the same time, and simultaneously improve the data transmission efficiency.
Fig. 4 is a flow chart of a third embodiment of a method for sharing media data by multiple applications provided by the present invention, as shown in fig. 4, on the basis of the above embodiment, before the sharing application sends a media data acquisition request to a master 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.
Because before the sharing application sends the media data obtaining request to the master application, it needs to determine whether the recording parameters of the media data needed by the sharing application are within the parameter range of the media data available to the master application, the sharing application needs to obtain the parameter range of the media data available to the master application before sending the media data obtaining request to the master application.
In this step, the sharing application sends query information to the master application, where the query information is used to query a parameter range of media data that can be provided by the master application.
It should be noted that, the triggering event that the sharing application sends the query information to the master application may be: the user wants to use the sharing application to realize services such as shooting video, recording audio or making video call, and clicks a button on a graphical user interface of the terminal device. The trigger event that the sharing application sends the query information to the master application may also be: after the master application and the sharing application are configured, the sharing application is started for the first time. The embodiment of the invention does not limit the triggering event of sending the query information to the main control application by the sharing application, and can be selected according to actual conditions.
S402: and the main 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 sharing application sends the query information to the master control application, the master control application receives the query information, so that the parameter range of the media data supported by the terminal device can be directly obtained.
Exemplary parameter ranges of the media data supported by the terminal device include: resolution ranges from 630ppi 360ppi to 3840ppi 2160ppi, frame rate ranges from 10fps to 120fps, sampling depth ranges from 16Bit to 24Bit, and sampling rate ranges from 44.1KHz to 48KHz. The embodiment of the invention does not limit the parameters and the parameter range of the media data supported by the terminal equipment, and can be selected according to actual conditions.
S403: and the master control application acquires 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 in which the master application obtains the parameter ranges of the media data that the master application can provide may be: after the main control application obtains the parameter range of the media data supported by the terminal equipment, the number of sharing applications for sharing the media data at the moment is obtained, and the parameter range of the media data which can be provided by the main control application is determined according to the number of sharing applications. The method comprises the steps of setting a mapping relation between the number of sharing applications for sharing media data and the proportion in a master control application, finding out the corresponding proportion according to the number, and selecting the range of the proportion from the parameter ranges of the media data supported by terminal equipment as the parameter range of the media data which can be provided by the master control application. The number of sharing 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 available by the master control application; the number of sharing applications for sharing 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 available by the master control application.
The manner in which the master application obtains the parameter ranges of the media data that the master application can provide 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 sharing application according to the number of sharing applications in the terminal device. The main control application is provided with a mapping relation between the number and the proportion of the shared application, the corresponding proportion is found according to the number, and the range of the proportion is selected from the parameter ranges of the media data supported by the terminal equipment and is used as the parameter range of the media data which can be provided by the main control application. The number of the shared applications in the terminal equipment is 1, the corresponding proportion is 100%, and the parameter range of the media data supported by the terminal equipment is used as the parameter range of the media data which can be provided by the main control application; the number of 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 which can be provided by the master control application.
S404: the master application sends the parameter ranges of the media data that the master application can provide to the sharing application.
In this step, after determining the parameter range of the media data that can be provided by the master application, the master application may send the parameter range to the sharing application, so that the subsequent sharing application may determine whether to send the media data acquisition request to the master application according to the parameter range of the media data that can be provided by the master application.
