And drastically increase producing efficiency.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also
To obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is a kind of method flow diagram of video and audio file synthesis of the embodiment of the present invention one.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
The embodiment of the present invention one discloses a kind of method of video and audio file synthesis, as shown in figure 1, comprising the following steps：
Step S101, raw media file is obtained from the network terminal.
Step S102, the raw media file is analyzed, wherein the raw media file includes at least two
Material.
Step S103, the material in the raw media file is merged, generate file destination.
Wherein, because the material format on the timeline all, in the absence of transcoding issues, simply again seals file
Fill, ensure that quick merging.In the case of form of the same race, the segments of timeline is within 30：
High definition H264 combined efficiencies 35: 1 (acquiescence 8Mbps),
SD H264 combined efficiencies 50: 1 (acquiescence 3.75Mbps)；
High definition Mpeg2-IBP combined efficiencies 30: 1 (acquiescence 15Mbps),
SD Mpeg2-IBP combined efficiencies 45: 1 (acquiescence 3.75Mbps).
Step S104, program file is exported after the file destination is packed.
What the technical scheme of the embodiment of the present invention was brought has the beneficial effect that：The embodiment of the present invention passes through to sequence time line
On material merge, by the out points part of all materials, lap, stunt part, subtitle parts etc. formed lattice
The unified material of formula, is exported after encapsulation, in the case where not losing program quality, ensure that the quick conjunction of media file
And drastically increase producing efficiency.
The embodiment of the present invention two discloses a kind of method of video and audio file synthesis, comprises the following steps：
Step S201, raw media file is obtained from the network terminal.
Step S202, the raw media file is analyzed, wherein the raw media file includes at least two
Material.
Wherein, the material format includes：H264, Mpeg2_ibp, DVD and VCD；
