In the specific implementation process, according to the needs of video type and video content, a target video can be arranged
A variety of or a kind of characteristic information, so as to the subsequent featured videos section that can extract a variety of or a kind of content.
Then, execute step S102, to the target video carry out characteristic matching, with determine in the target video with
The matched target frame of characteristic information.
In the specific implementation process, characteristic information is different, and corresponding matching process is also different:
If the characteristic information is image feature information, each frame image of characteristic information and target video is carried out
Images match, or the interval frame image of characteristic information and target video is subjected to images match, it is deposited on certain frame image when matching
In image corresponding with this feature information, it is determined that the frame is target frame.For example, it is assumed that characteristic information is blood cake pattern, then
When matching the frame comprising the blood cake pattern, then using the frame image as target frame.
If the characteristic information is voice characteristics information, the audio file of characteristic information and target video is subjected to sound
Frequency matches, when match somewhere audio and this feature information to it is corresponding when this at the corresponding frame of audio be target frame, specifically
For at this corresponding frame of audio be time stab information and the consistent frame of audio file time stab information at this.For example, it is assumed that feature is believed
Breath is that " killing success " pronounces, then when matching the audio file comprising audio, then with identical with the time stamp of the audio file
Frame is as target frame.
Certainly, the method for carrying out characteristic matching is not limited to above two, and this is not restricted, also will not enumerate.
Next, executing step S103, rule is intercepted according to the target frame and preset featured videos, in the target
Featured videos section is determined in video, the featured videos section includes the target frame, featured videos interception rule with it is described
Characteristic information is corresponding.
In the embodiment of the present application, rule is intercepted according to the preset featured videos, determines the featured videos section
The end frame of playing duration and the featured videos section of the start frame away from the target frame away from the playing duration of the target frame,
Wherein, in the target video, the play position of the start frame is located at before the target frame or is equal to the target frame,
The play position of the end frame is located at after the target frame or is equal to the target frame.
Specifically, the featured videos interception rule is corresponding with the characteristic information, refers to, different features is believed
Breath has corresponding featured videos interception rule, for example:
Assuming that this feature information is to include in the game video for kill plot, characterization game kills successful information, considers
To excellent aiming and kill probably occur killing successfully first 1 minute or so time, then such characteristic information can be set
Corresponding featured videos interception rule are as follows: determine target frame forward 60s to the video between the target frame be featured videos section.
Assuming that this feature information is in prize drawing class video, characterization starts the information announced the winners in a lottery, it is contemplated that duration of announcing the winners in a lottery is general
The corresponding featured videos interception rule of such characteristic information then can be set are as follows: determines that target frame starts to 180s backward in 180s
Between video be featured videos section.
Certainly, in addition to determined above by characteristic information type featured videos end duration and with the time location of target frame
Relationship, so that it is determined that featured videos interception rule is outer, there are also the methods that other determine featured videos interception rule.For example, may be used also
Multiple characteristic informations are arranged, using the video between certain corresponding target frame of two characteristic informations as featured videos section.Citing
For, it is assumed that prize drawing class video, it is provided with characterization and starts the characteristic information A to announce the winners in a lottery and characterize the characteristic information B for end of announcing the winners in a lottery,
It matches characteristic information A and corresponds to target frame A, characteristic information B corresponds to target frame B, then corresponding featured videos interception can be set
Rule are as follows: determine that the video between target frame A and target frame B is featured videos section.
After determining featured videos section, step S104 is executed, the featured videos section is extracted from the target video.
In the specific implementation process, the featured videos section is determined, it can determine rising for the featured videos section
Beginning time stamp and end time stamp, terminate the featured videos between time stamp to extract the starting time stamp and this from the target video
Section.
In view of the extraction of featured videos section needs to consume more calculating and process resource, the present embodiment additionally provides one
The extracting method of kind low consumption of resources, is described in detail as follows:
Referring to FIG. 2, due to target video be broadcast live or history live streaming live video, transmission of video be by
It is interspersed with transmission according to video unit and audio unit, each video unit and audio unit have its corresponding time stab information,
Therefore the present embodiment is not decoded the target video section, directly pulls live stream, Xie Liufu by step S201~S204
With rear, the immediate video of time stab information of corresponding time stab information Yu the target frame is searched in not decoded target video
Unit according to the immediate video unit determination and extracts the featured videos section, then is flowed by step S205~S206
The featured videos section that multiplexing synthesis and preservation extract.For example, as illustrated in fig. 2, it is assumed that video unit 3 and video unit 4
Time stamp and the featured videos section determined time stab information it is closest, then solve stream multiplexing and extract the video unit 3 and video
Unit 4, and after extracting time stab information audio unit corresponding with video unit 3 and video unit 4, then stream multiplexing is carried out, it closes
At video unit and audio unit, to form the complete featured videos section extracted.
Using this featured videos section extracting method, due to not needing to be decoded to entire video, can save more
Calculating and process resource improve processing speed.
Further, it is contemplated that some featured videos sections have strict requirements to the time, can also be arranged and carry out excellent view again
Before frequency extraction, the attribute information of the target video is first obtained；Whether the target video is judged according to the attribute information
It needs precisely to extract mode using time stamp；If it is required, then carrying out video decoding to the target video；And according to described excellent
Video intercepting rule, according to the time stab information of decoded target video, is extracted described excellent from decoded target video
Video-frequency band；If it is not required, then searching the time stamp of corresponding time stab information Yu the target frame in not decoded target video
The immediate video unit of information, wherein the target video includes N number of video unit, and N is the positive integer greater than 1；According to institute
It states immediate video unit determination and extracts the featured videos section.
I.e. featured videos section corresponding according to every category feature information by staff the case where, in advance in the category of target video
Property information in setting characterization whether need precisely to extract the extraction information of mode using time stamp, for example, it is desired to accurate using time stamp
