Description
Technical field
The invention belongs to communication technical field, a kind of method particularly relating to PPT file process
And device.
Background technology
Along with the fast development of mobile field technology, office software the most slowly develops into move from computer
Dynamic terminal, but the file format above computer terminal is varied, therefore partial document form
Face is incompatible on mobile terminals.Therefore prior art there is problems of, and broadcasts at mobile terminal
When putting PPT file, it is possible that following problem include animation effect do not have, word sometimes
Time has mess code appearance, photo resolution is the highest and the controllable property of PPT file is poor.
Summary of the invention
The purpose of the embodiment of the present invention is to provide the method and device of a kind of PPT file process,
With solution prior art when mobile terminal playing PPT file, it is possible that following problem
Do not have including animation effect, word sometimes have mess code occur, photo resolution the highest and
The problem of PPT file controllable property difference.
Embodiments of the invention are realized in, a kind of method of PPT file process, described
Method comprises the following steps:
When playing PPT file, intercept broadcast window picture according to default frequency, and press
According to the order intercepted to described broadcast window picture number；
The described broadcast window picture intercepted is converted into video file.
The another object of embodiments of the invention is to provide the device of a kind of PPT file process,
Described device includes:
Interception unit, for when playing PPT file, intercepts according to default frequency and plays
Window picture, and according to the order intercepted to described broadcast window picture number；
Converting unit, for being converted into video file the described broadcast window picture intercepted.
The embodiment of the present invention provides the method and device of a kind of PPT file process, by by PPT
File is converted into video file, and playing video file substitutes PPT file on mobile terminals,
Solve prior art when mobile terminal playing PPT file, it is possible that following problem
Do not have including animation effect, word sometimes have mess code occur, photo resolution the highest and
The problem of PPT file controllable property difference.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that under,
Accompanying drawing during face describes is only some embodiments of the present invention, for ordinary skill people
From the point of view of Yuan, on the premise of not paying creative work, it is also possible to obtain according to these accompanying drawings
Other accompanying drawing.
Fig. 1 is the flowchart of the method for the PPT file process that the embodiment of the present invention provides；
Fig. 2 is the function structure chart of the device of the PPT file process that the embodiment of the present invention provides.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with
Drawings and Examples, are further elaborated to the present invention.Should be appreciated that this place is retouched
The specific embodiment stated only in order to explain the present invention, is not intended to limit the present invention.

Specifically include:
S11, when playing PPT file, intercept broadcast window picture according to default frequency,
And according to the order intercepted to described broadcast window picture number.
S12, intercept described broadcast window picture be converted into video file.
In the present embodiment, generally using FFmpeg coding and decoding video storehouse, other video is compiled
Decoding storehouse can also use, but uses FFmpeg coding and decoding video storehouse effect more preferable.
Optionally, it is achieved the method for S12 particularly as follows:
Use FFmpeg coding and decoding video storehouse, the described broadcast window picture intercepted is generated
MP4 file.
Optionally, also included before described step S11:
Read the information of PPT file and generate PPT message file, described PPT message file
The record number of pages of PPT, animation sequence and key frame temporal information and key frame temporal information
Corresponding animation and the PPT page number.
Optionally, said method also includes:
Receiving the order of playing video file, key frame temporal information is carried in described order, according to
The key frame temporal information that described order is carried inquires about described key frame in PPT message file
Animation that temporal information is corresponding and the PPT page number, and animation is shown on a display screen.
In the present embodiment, when accessing video file on mobile terminals, it is sometimes necessary to directly
Access information corresponding to certain key frame time, use the described key frame temporal information can be direct
Have access to animation corresponding to key frame time, improve efficiency.
Optionally, in the information of described reading PPT file and generate PPT message file, institute
State the number of pages of PPT message file record PPT, animation sequence and key frame temporal information and
Also include before animation that key frame temporal information is corresponding and the PPT page number:
Call com component that OFFICE provided to read PPT file.
In the present embodiment, com component that OFFICE provided is being called to read PPT
Before file, it is also possible to including:
Start the service of monitoring, whether scanning monitored directory has PPT file.
There is PPT file it should be noted that once scan in monitored directory, will adjust
The com component provided with OFFICE reads PPT file.
Embodiments provide the device of PPT file process, described as shown in Figure 2, tool
Body includes:
Interception unit 21, for when playing PPT file, intercepts according to default frequency and broadcasts
Put window picture, and according to the order intercepted to described broadcast window picture number；
Converting unit 22, is converted into video file the described broadcast window picture intercepted.
