Abstract

Disclosed is a multimedia data processing method by a framework, in which the framework is capable of directly controlling data input and output of components in a state of the framework being interposed between the components and an application program, thereby reducing the time and effort involved in developing the components or the application program.

Claims

1. A method of processing multimedia data, the method comprising:

inquiring each of a plurality of software components, by a multimedia framework, about a communication mode that is supported by each of the plurality of software components, the communication mode comprising an indirect communication mode, which enables the multimedia data to be transmitted between the plurality of software components under control of the multimedia framework, and a direct communication mode, which enables the multimedia data to be transmitted directly between the plurality of software components without control of the multimedia framework;

determining, by the multimedia framework, whether an application program generates a data transmission request;

determining, by the multimedia framework, the communication mode of each of the plurality of components;

in response to the application program generating the data transmission request and a first component among the plurality of software components being in the indirect communication mode, constructing a media graph based on the indirect communication mode, transmitting the multimedia data from the first component to the multimedia framework, transmitting the multimedia data from the multimedia framework to the application program, and transmitting the multimedia data from the application program to a second component among the plurality of software components through the multimedia framework, the multimedia data being a single unit of multimedia data stream which continuously streams through the first component, the multimedia framework, and the application program; and

in response to the application program not generating the data transmission request or the first component being in the direct communication mode, constructing the media graph based on the direct communication mode and transmitting the multimedia data directly from the first component to the second component.

2. The method as claimed in claim 1, wherein the constructing the media graph comprises constructing the media graph using the indirect communication mode when the application program generates data transmission request although the first component supports the direct communication mode.

3. The method as claimed in claim 2, further comprising notifying the application program of a failure in response to a construction of the media graph using the indirect communication mode being failed, and constructing the media graph using the direct communication mode in response to the failure being notified.

4. The method as claimed in claim 1, further comprising generating a handler configured to process the multimedia data of the first component in response to the media graph being constructed by the indirect communication mode.

5. A non-transitory computer readable recording medium storing a program that is executable to perform a method of processing multimedia data comprising:

inquiring each of a plurality of software components, by a multimedia framework, about a communication mode that is supported by each of the plurality of software components, the communication mode comprising an indirect communication mode, which enables the multimedia data to be transmitted between the plurality of software components under control of the multimedia framework, and a direct communication mode, which enables the multimedia data to be transmitted directly between the plurality of software components without control of the multimedia framework;

determining, by the multimedia framework, whether an application program generates a data transmission request;

determining, by the multimedia framework, the communication mode of each of the plurality of components;

in response to the application program generating the data transmission request and a first component among the plurality of software components being in the indirect communication mode, constructing a media graph based on the indirect communication mode, transmitting the multimedia data from the first component to the multimedia framework, transmitting the multimedia data from the multimedia framework to the application program, and transmitting the multimedia data from the application program to a second component among the plurality of software components through the multimedia framework, the multimedia data being a single unit of multimedia data stream which continuously streams through the first component, the multimedia framework, and the application program; and

in response to the application program not generating the data transmission request or the first component being in the direct communication mode, constructing the media graph based on the direct communication mode and transmitting the multimedia data directly from the first component to the second component.

6. The non-transitory computer readable recording medium storing a program for executing the method as claimed in claim 5, the constructing the media graph comprises constructing the media graph using the indirect communication mode when the application program generates the data transmission request although the first component supports the direct communication mode.

7. The non-transitory computer readable recording medium storing a program for executing the method as claimed in claim 6, wherein the method further comprises notifying the application program of a failure in response to a construction of the media graph using the indirect communication mode being failed, and constructing the media graph using the direct communication mode in response to the failure being notified.

8. The non-transitory computer readable recording medium storing a program for executing the method as claimed in claim 5, wherein the method further comprises generating a handler configured to process the multimedia data of the first component in response to the media graph being constructed by the indirect communication mode.
