Embodiment 2
The flow diagram of the method second embodiment of video clip is intercepted as indicated at 3 in the embodiment of the present invention.
Step 21, mobile terminal receive the interception initiation command that user submits, and mark and remember in current video broadcast interface
To intercept starting point, i.e. locus intercepting starting point, while recording the broadcasting attribute of interception starting point；
The present invention will intercept the broadcasting attribute record of starting point, heretofore described broadcasting attribute tool by writing function
Body be corresponding to the position that is indicated in original video by time point and it is currently playing in a manner of, the currently playing mode is including broadcasting
It puts, F.F., slow-motion, rewind and move back slowly.
Wherein, user submits interception order to submit interception life by " starting to intercept " pre-set button in video playing interface
It enables.Mobile terminal receives the interception order of user's triggering, marks in current video broadcast interface, and the presentation mode of the label can be with
For flashing interception symbol on corner any on currently playing interface；Or display interception symbol, and show interception time, it is similar
In the existing video capture function of mobile phone, symbol is revealed as " interception 00:00 " when citing interception starts.
And in another embodiment, of the invention can carry out video intercepting in the mode of " rewind " or " moving back slowly ",
For this video intercepting for falling back type, the equally interception symbol when starting interception is " interception 00:00 ", is cut with falling back
The time taken, the time for intercepting symbol increase accordingly.
Wherein, it should be noted that in the embodiment of the present invention, signified video content is suitable to the video flowing recorded
Answering property is more preferably.
Step 22, mobile terminal carry out corresponding play operation to video by single or multiple play operation dot commands,
Locus intercepting is covered along track is played, wherein when replacing play operation dot command, system records the broadcasting category of the point
Property；
The video playing carried out under play operation point, the time (i.e. interception time) for intercepting symbol increases therewith, just
When often playing, the time, normal recordings, such as interception started according to normal play 60s, and then symbol is revealed as " interception 01:00 "；
In quick play, the time, such as one times of broadcasting 30s of F.F., then the time increase accordingly one times, and symbol is aobvious according to times speed recording is played
It is shown as " interception 01:00 "；In slow play, the time according to times speed recording, such as one times of broadcasting 60s at a slow speed is played, then time phase
One times should be reduced, symbol is shown as " interception 00:30 "；The time of symbol is intercepted always with the real time of normal playback speed

And the setting meaning that operating point is put in this multicast is: (1) intercepting video person can intuitively carry out in broadcasting
The adjustment for intercepting efficiency can then take fast-forward mode if operator feels to intercept when leading portion and is not desired to waste time；For another example
When operator plays to some interface, think that the interface does not need to intercept, then rewind can be used or the slow mode of moving back is retreated, In
While such inverse operations, corresponding reduction occurs for the time shown in interception label, such as normal reverse plays 30s, then shows
The time shown accordingly reduces 30s；Even if going back on one's word after operator retreats continues the broadcasting that moves ahead, broadcasting, F.F. or slow can switch to
Into play mode, and intercept time for showing in label and then increase by above-mentioned rule.(2) interception video person can work as in broadcasting
Front interface moves back the reversed interception that mode carries out video using rewind or slowly, when the time shown in interception label is practical according to video
Length is shown.
According to above-mentioned rule, the randomness and flexibility of interception video are realized；Locus intercepting is covered along track is played,
When replacing play operation dot command, system records the broadcasting attribute of each play operation point.
Step 23 plays in video, and in the terminal that last play operation point plays, mobile terminal receives user and submits
Interception terminate order, be interception terminating point in currently playing Interface Mark, stop interception movement, record interception terminating point is broadcast
Attribute is put, and tentatively generates interception video clip；
Need to illustrate when, the step generate interception video clip be preliminary segment, for without reparation interception regard
Frequency segment, which, which can be, plays the lower video clip intercepted according to normal play mode, and this video clip is
It does not need to be repaired；It is also possible to include broadcasting, F.F., slow-motion, rewind or move back middle more than two play mode slowly and broadcast
The video clip of interception is put down, and this kind of video clip is then to be repaired.
After step 24, interception movement stop, locus intercepting is repaired, generates final interception video clip；
Specifically include following two contents:
1, determine that interception terminates section according to the broadcasting attribute of record, judge that interception terminates the type of gesture of section, and it is corresponding into
Row is repaired.
Wherein it is determined that interception terminate section method are as follows: by the starting point to the end of the last one play operation point of record it
Between broadcasting track be judged to intercepting termination section.
If the track that interception terminates section is single-track, determining that interception terminates section final on trajectory is video intercepting terminal, is cut
The track that plays for taking track to be covered is the video clip intercepted；If it is dual trace that interception, which terminates track corresponding to section,
(referring to that track number is 2) or multi-trace (referring to that track number is greater than 2), determining that interception terminates section final on trajectory is video intercepting terminal, will
First segment track and interception terminate section trajectory extraction in dual trace or multi-trace, and by the play position and interception of first segment track
The play position for terminating section track compares, and is judged whether there is in conjunction with interception starting point beyond in target interception video clip
Hold, if there is then cutting off, obtains the target video segment to be intercepted.Specific judgment method is as follows:
When the track of the interception termination section is single-track, comprising:
(1) play position of starting point is intercepted before the play position of interception terminating point, and interception terminates that section is last broadcasts
Operational order is put as broadcasting, F.F. or slow-motion, then interception, which terminates section, plays the video that the path that track is covered is interception
Segment.Shown in Fig. 3 first segment, the starting point A of segment is intercepted in former play time (i.e. play position) 02:00 played in video
Before the play position 08:32 of interception terminating point B, and intercepting the last play operation order of termination section a is preceding progressive die
Formula (broadcasting, F.F. or slow-motion)；So, it is the video clip intercepted that interception, which terminates section and plays the path that track is covered,.
(2) play position of starting point is intercepted after the play position of interception terminating point, and interception terminates that section is last broadcasts
It puts operational order to be rewind or move back slowly, then playing the path that track is covered is the video clip intercepted.Fig. 3 second segment institute
Show, the starting point A for intercepting segment is intercepting terminating point B's in former play time (i.e. play position) 08:00 played in video
Behind play position 02:14, and intercepting the last play operation order of termination section a is " fall back " mode" (rewind or moving back slowly)；
So, it is the video clip intercepted that interception, which terminates section and plays the path that track is covered,.
When the track that the interception terminates section is dual trace (track number is 2), comprising:
(1) play position of starting point is intercepted before the play position of interception terminating point, first segment track in dual trace
(track i.e. in dual trace under first play operation dot pattern) and interception termination section track play out position and compare, and will play
Position is greater than the video content excision that interception terminates segment endpoint play position.Shown in Fig. 4 first segment, the starting point A of segment is intercepted
Play position 02:00 interception terminating point B play position 08:32 before, interception terminate section a it is last play operation life
Enabling is " fall back " mode" (rewind or moving back slowly), then in the interception video clip tentatively generated, play position is greater than to the view of 08:32
Frequency content is deleted.
(2) when intercepting the play position of starting point after intercepting the play position of terminating point, first segment track and interception
Termination section track plays out position and compares, and the video content that play position is less than interception termination segment endpoint play position is cut
It removes.Shown in Fig. 4 second segment, play position 02:14 of the play position 08:00 in interception terminating point B of the starting point A of segment is intercepted
Behind, it is forward mode (broadcasting, F.F. or slow-motion) that interception, which terminates the last play operation order of section a, then is tentatively generating
Interception video clip on, by play position less than 02:14 video content delete.
Shown in Fig. 5, when the track of the interception termination section is multi-trace (track number is greater than 2), comprising:
(1) when the play position of interception starting point is before the play position of interception terminating point, except first segment in multi-trace
Track and the track intercepted outside termination section track are cut off, and first segment track and interception termination section track play out position and compare,
Play position is greater than the video content excision that interception terminates segment endpoint play position, wherein if first segment track and interception are eventually
Only the play position of section track has overlapping, then intercepts and terminate lap excision in section track.
Shown in Fig. 5 (first, second and third section), the play position 02:00 of the starting point A of segment is intercepted interception terminating point B's
Before play position 09:30, interception terminates the last play operation order of section a1 as forward mode (first and second section of institute in figure
Show) or " fall back " mode" (in figure shown in third section)；So, in the interception video clip tentatively generated, first segment track is removed
An and interception terminate outside section a1 reservation, other tracks a2, a3... are cut off, and by the play position of first segment track an and cut
The play position for terminating section a1 is taken to compare, the video content that will be greater than terminating point play position 09:30 is deleted；If first segment track
The play position that an and interception terminate the track section a1 has overlapping, then interception is terminated the lap in the track section a1 and cut off.
(2) play position of starting point is intercepted after the play position of interception terminating point, except first segment rail in multi-trace
Mark and the track intercepted outside termination section track are cut off, and first segment track and interception termination section track play out position and compare, by
Play position is less than the video content excision that interception terminates segment endpoint play position, wherein if first segment track and interception terminate
The play position of section track has overlapping, then intercepts and terminate lap excision in section track.
Shown in Fig. 5 (third and fourth section), play position 08:00 the broadcasting in interception terminating point B of the starting point A of segment is intercepted
Put behind the 02:14 of position, interception terminate the last play operation order of section an be forward mode (in figure shown in third section) or
Person's " fall back " mode" (in figure shown in the 4th section), then, in the interception video clip tentatively generated, except first segment track an and cut
It takes and terminates outside section a1 reservation, other tracks a2, a3... are cut off, and the play position of first segment track an and interception are terminated
Section a1 play position compare, will less than terminating point play position 02:14 video content delete, if first segment track an and cut
It takes the play position for terminating the track section a1 to have overlapping, then interception is terminated into the lap in the track section a1 and cut off.
2, it when in the video intercepting segment there are two above overlapping tracks, carries out deleting reparation.
Detect the interception video clip track tentatively generated: there are two above overlapping tracks in the video intercepting segment
When, then retain first segment overlapping tracks and final stage overlapping tracks, remaining excision；By first segment overlapping tracks and final stage
Overlapping tracks play out position and compare, and if any overlapping, then lap is cut off in final stage overlapping tracks, and retain
First segment overlapping tracks and final stage overlapping tracks incision are spliced.
As shown in fig. 6, overlapping tracks section is CD, first segment overlapping tracks c1 and final stage overlapping tracks cn reservation,
Remaining overlapping tracks c2, c3... excision, then detects whether first segment overlapping tracks c1 and final stage overlapping tracks cn has weight
