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, intercepting rule according to the target frame and preset featured videos, essence is determined in the target video
Color frequency range, the featured videos section include the target frame, and the featured videos interception rule is corresponding with the characteristic information.
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 intercept rule：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
180s, then the corresponding featured videos interception rule of such characteristic information, which can be set, is：Determine that target frame starts to 180s backward
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
