First the implementation for extracting specific video clip according to user behavior will be illustrated below.
Referring to Fig. 3, which is provided by the embodiments of the present application a kind of according to user behavior extraction specific video clip method Flow chart, as shown in figure 3, this method may include:
S301: the data of the history playback progress adjustment behavior for the first video file are obtained.
It, can be by video playing client to when each user is when watching the first video file in the present embodiment The playback progress of one video file is adjusted, meanwhile, client can recorde user to the first video file playback progress The behavioral data generated when adjustment, and the behavioral data of record can be sent to server.It is literary when needing to obtain the first video When the short-sighted frequency of part, each user is obtained first, generated number when history playback progress adjusts is carried out to the first video file According to.The data can be to adjust time data when the first video file playback progress, for example, user is in the first video file The adjustment for sometime playing out progress stops the adjustment etc. of playback progress at another moment of the first video file.
It is understood that user for the first video file playback progress adjustment mode can there are many.User The adjustment of progress can be played out by triggering the corresponding fast forward button of the first video file or fast backspace key, it can also be by dragging The playing progress bar for moving first video file is adjusted.No matter which kind of user adjust playback progress in the way of, corresponding Initial time and end time are adjusted, then the adjustment initial time and end time are to be directed to broadcasting for the first video file The data of progress adjustment behavior are put, then S302 can be executed according to the initial time and end time.
Wherein, when user carries out F.F. adjustment to playback progress, the initial time of adjustment is earlier than the end time；Work as user When carrying out retreating adjustment to playback progress, the initial time of adjustment is later than the end time.For example, user watches " Ah sweet's main story " When, the F.F. since the 10th minute stopped F.F. at the 13rd minute, then the initial time adjusted is the 10th minute, at the end of Between be the 13rd minute；When user retreated since the 50th minute, in stopping in the 45th minute, then the initial time adjusted was the 50th point Clock, end time are the 45th minute.
S302: adjusting the data of behavior according to playback progress, determine in the first video file effective F.F. period and/or Effective rewind period.
In the present embodiment, when the corresponding time data of acquisition user's adjustment playback progress, the first video text can be determined Part corresponding effective F.F. period and/or effective rewind period, so as to according to effective F.F. period and/or effective rewind Period extracts specific video clip.
Wherein, effective F.F. period can be understood as having in the first video file that have carried out playback progress compared with multi-user fast Into period.Effective rewind period, which can be understood as having in the first video file, has carried out playback progress progress compared with multi-user The period of retrogressing.Effective F.F. period may be the period being not concerned in the first video file compared with multi-user, and to have The end time of effect F.F. period is that the video clip of starting point may be that most of user is interested.Effective rewind period It may be the period for watching, comparing concern in the first video file again compared with multi-user.
In practical applications, there may be maloperations when adjusting for user to playback progress, and need to guarantee to obtain Take multiple effective F.F. periods and/or effective rewind period.The history then obtained for first video file plays The specific implementation of the data of progress adjustment behavior may include: to obtain target user's going through at least twice for the first video file History playback progress adjust behavior data, and between any history playback progress adjustment behavior twice of same target user when Between interval be greater than preset time threshold, target user be any one or more users.It adjusts and goes further according to playback progress later For data, determine effective F.F. period and/or effective rewind period in the first video file.So as to avoid obtaining By the data for the history playback progress adjustment behavior that the maloperation behavior of user generates.
To allow the effective F.F. period obtained and/or effective rewind period preferably to reflect most users Behavior can determine that multiple historical users produce respectively according to user to the data of the first video file playback progress adjustment behavior The raw F.F. period and/or rewind period；Then multiplicity in the F.F. period is higher than to the time of the first preset condition Section is determined as effective F.F. period；The period that multiplicity in the rewind period is higher than the second preset condition is determined as effectively The rewind period.
In practical application, being directed to first video file, multiple historical users are obtained for first video file Playback progress be adjusted generated data, and then determine F.F. period and/or rewind time that each user generates Section.It is then possible to which number of repetition in multiple historical users corresponding F.F. period to be higher than to the period of the first preset condition As effective F.F. period, and/or, number of repetition in multiple historical users corresponding rewind period is higher than second and is preset The period of condition is as effective rewind period.
For example, being directed to film " Ah sweet's main story ", the F.F. period that user A is generated is -13 minutes the 10th minute, the 25th point Clock -31 minutes；The F.F. period that user B is generated is -13 minutes the 11st minute, -33 minutes the 26th minute；What user C was generated The F.F. period is -14 minutes the 11st minute, then repetition in -13 minutes the 11st minute in the F.F. period that three users generate Degree is 3, and -31 minutes the 26th minute multiplicities are 2, when the first preset condition is 2, then really by -13 minutes the 11st minute It is set to effective F.F. period, executes S303.
For another example the rewind period that user A is generated is-the 55 minute, -40 minutes the 44th minute the 60th minute；User B The rewind period of generation is -52 minutes the 57th minute, -38 minutes the 43rd minute；The rewind period that user C is generated is the 58th Minutes -51 minutes, -40 minutes the 43rd minute, then repetition in -55 minutes the 57th minute in the rewind period that three users generate Degree be -40 minutes the 3, the 43rd minute multiplicity be 3, when the second preset condition be 2 when, then by -55 minutes the 57th minute and It is determined as within -40 minutes within 43rd minute effective rewind period, executes S303.
