Specific implementation mode
The disclosure is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the disclosure, rather than the restriction to the disclosure.It also should be noted that in order to just
It is illustrated only in description, attached drawing and the relevant part of the disclosure rather than entire infrastructure.
It should be mentioned that some exemplary embodiments are described as before exemplary embodiment is discussed in greater detail
The processing described as flow chart or method.It is therein to be permitted although each step to be described as to the processing of sequence in flow chart
Multi-step can be implemented concurrently, concomitantly or simultaneously.In addition, the sequence of each step can be rearranged, when its operation
The processing can be terminated when completion, it is also possible to the other steps being not included in attached drawing.Processing can correspond to
In method, function, regulation, subroutine, subprogram etc..
Fig. 1 is a kind of method flow diagram of media file playing method first embodiment provided in an embodiment of the present invention.It should
Media file playing method is applied to terminal, and the terminal can be mobile terminal, computer, desktop computer, tablet computer etc.,
Or smart mobile phone, e-book, wearable device etc..The terminal can be by installing application program or built-in application
The method that the form of program realizes playback of media files in the embodiment of the present invention, the media file can come from lattice chain
The file on file or network server connected, the embodiment of the present invention are not limited thereto.The playback of media files side
Method includes the following steps S101-S105.
In step S101, play instruction is received, media file to be played is obtained according to play instruction.
Specifically, the play instruction can be by after the specific application program of installation, passing through and clicking application program
Interior corresponding object generates, and can also be to be generated by forms such as phonetic order, gesture instructions.It is obtained according to the play instruction
Corresponding media file to be played.It is understood that the media file to be played can be the file being locally stored,
It can also be the file for being stored in network side, at this time by accessing corresponding network address, read the file in network side in real time,
It realizes and is played in caching.
In step s 102, the target file type of the media file and the attribute information of mobile terminal are obtained.

The file of network side can be also packaged, the tunneling includes RTMP during streaming media using certain agreement
(Real Time Messaging Protocol, real-time messages transport protocol), RTSP (Real Time Streaming
Protocol, real time streaming transport protocol) and HTTP (HyperTextTransferProtocol, hypertext transfer protocol).When
When using different agreements, the format of stream medium data will be different.Before the decoding, first can be by media file solution agreement, this
In embodiment, since the step of solution agreement, is all made of the prior art, and to carry out related description, this field to the step of solution agreement
Technical staff it is understood that can first carry out the action of solution agreement before decoding.
The attribute information of the mobile terminal includes the type of decoding assembly and the file type of support.The attribute letter
Breath can be obtained by accessing the system information of the mobile terminal.The decoding assembly includes：Image processor (GPU), number
Word signal processing component (DSP) and field programmable gate array chip (FPGA).It is different since the type of mobile terminal is different
Mobile terminal decoding assembly it is different, corresponding function is also different.By obtaining the attribute information of mobile terminal, can understand
The specific decoding assembly information of mobile terminal, to further appreciate that the decoding assembly corresponds to the file format supported.
In step s 103, if the attribute information shows that the decoding assembly of the mobile terminal supports the file destination
Type, it is determined that carry out hard decoder.
Specifically, after obtaining attribute information, by attribute information the corresponding file format of decoding assembly and institute
It states target file type to be compared, judges whether the decoding assembly supports the target file type.If supporting, it is determined that
To carry out hard decoder.
Optionally, in other embodiments, in addition to judging whether decoding assembly supports the target file type, into one
Step also needs to consider decoding assembly when decoding the media file of the target file type, it is possible to create resource consumption,
Such as hardware utilization, power consumption etc., so as to more accurately judge whether to need to use hard decoder.
In step S104, the decoding assembly is called to carry out hard decoder processing to the media file.
Specifically, when determining using hard decoder, decoding assembly is called to carry out hard decoder processing.According to mobile terminal
Difference, the decoding assembly chosen at this time can also be different.If more powerful than the GPU of mobile terminal, then GPU may be used
Decoding；If mobile terminal uses the DSP for being exclusively used in sound quality promotion, DSP decodings may be used.It is understood that also wrapping
Some other situation is included, the embodiment of the present invention is not limited thereto.
In step S105, broadcast decoder treated file.
Specifically, after the decoding, according to decoded original video files and original audio file, when carrying out subsequent
Between the processing such as synchronize, and execute subsequent playback action.
Media file playing method in the embodiment of the present invention, by the category for obtaining file type and current mobile terminal
Property, judge corresponding coding type, so as to targetedly select corresponding coding type according to file type, improves
The specific aim of decoding process reasonably utilizes resource, enhances the stability of playing process.
