Understand the disclosure, and can by the scope of the present disclosure it is complete convey to those skilled in the art.
As shown in figure 1, a kind of video segmentation loading method is provided in one embodiment of the present of invention, bag
Include：
Step 110, according to loading first paragraph video temporal information, and first paragraph video length, meter
Calculate loading velocity during loading first paragraph video；First paragraph video is obtained by server from cutting on pre- setting video
Arrive.The temporal information of first paragraph video can include beginning request time and the loading of loading first paragraph video
Deadline, it is possible thereby to the temporal information according to first paragraph video is calculated loading first paragraph video
Short time consumption.In the present embodiment, it can also be multiple that the quantity of first paragraph video can be one.Root
According to the technical scheme of the present embodiment, the principle for calculating video loading velocity is：When player user end to
Server sends request to obtain during video segment, and record starts request time ts1, when the segmenting video adds
A time te1 is recorded after the completion of load, the short time consumption that can obtain loading this section of video using te1-ts1 is
t1；This section of length of video is L1, then can be obtained by obtaining the L1 seconds video of length in t1 seconds,
So probably it is estimated that the video length of loading per second is L1/t1, if for example obtain 20 seconds regarded
Frequency takes 5 seconds, then can be simply considered that the network speed of user each second can obtain 4 for user
The video content of second.
Step 120, when first paragraph video to preset length is played, according to the residue length of first paragraph video
And the loading velocity of first paragraph video, calculate the length of the second segment video for treating to load to server request.
First paragraph video and second segment video are two video-frequency bands adjoined each other in pre- setting video, and the first video
Section end time with the beginning of the second video-frequency band between it is identical.In the present embodiment, in first paragraph video
In playing process, when the 50% of video playback to this section of video length (value can be adjusted), start
Next section of video of loading.Because the video that there remains 50% is not played, if the length of first paragraph video is
20 seconds, then remaining video can probably play 10 seconds；Because per second probably can acquisition 4 seconds regards
Frequently, then general user obtains 40 seconds videos of length in ensuing reproduction time.If regarded certainly
The total length of frequency is less than end position, and end position is the position of video footage.
Preset length in addition to it can be the setting ratio of each video-frequency band duration, in can also be each video-frequency band
Preseting length (such as the 10th second in the video-frequency band) or setting frame number (such as in the video-frequency band the
120 frames) etc..
Step 130, according to the length of second segment video, the request of loading second segment video is sent to server.
Step 140, the second segment video obtained from cutting on pre- setting video that load server sends for
Play.The technical scheme of the present embodiment can be performed cyclically, until whole video loading is completed.For example,
After video player obtains second segment video, the time te2 that record time started ts2 and video loading are completed,
So as to calculate loading second segment L2=32 seconds the time t2 of video, such as t2=6s, according to first paragraph video
Loading velocity and second segment video loading velocity, calculate the video that can be loaded average each second long
Degree, (L1+L2)/(t1+t2)=(20+32)/(5+6)=4.7.So when second segment video playback to this section of video
When 50%, start to load the 3rd section of video.If the total length of video is less than end position, end position is
The position of video footage.It can be seen that according to above-mentioned calculation procedure, can calculate successively next will play
Video segment length, until whole video playback complete.
As shown in Fig. 2 a kind of video segmentation loading method is provided in one embodiment of the present of invention, bag
Include：
Step 210, when any part of pre- setting video is not loaded, the pre- setting video of loading is sent to server
In default second length one section of request of video.This section of video for obtaining can be regarded as first first paragraph
Frequently.By taking html5video video players as an example, when user opens a page carries out video-see,
Html5video video players on the page first obtain the information of whole video, including video from server
Title, video footage, video size, video url (address) etc..If a video very little, than
Such as less than 1M, it is not necessary to which broadcast multiple segments voice separately is carried out to video；If video is relatively large, it is necessary to right
Video is segmented.Specifically, when first segmentation of loading is needed, one length of loading can be fixed,
Such as 20 seconds.So need to take starting position 0 and stop bits when the url of video player is set
Put 20 the two parameters.The url of such as video is www.videourl.com/12345, the acquisition of transmission
It is www.videourl.com/12345 that first url of segmentation is included in the request of videoSt=0＆et=20,
Wherein st=20 represents that starting position is 0 second, and et=20 represents that end position is 20 seconds.
Server is received comprising www.videourl.com/12345After the request of st=0＆et=20, according to
Www.videourl.com/12345 is known that the position of former video, and then server enters to the video
Row cutting one provisional video of 0~20 second of generation, and data flow is returned into player；When data flow is returned
Return after completing, delete the provisional video；Or the provisional video that will not be generated when video is cut is preserved
Onto hard disk, but it is saved directly in internal memory, directly using in internal memory during server return video flowing
Data, server clears data after the completion of returning.
Step 220, according to loading first paragraph video temporal information, and first paragraph video length, meter
Calculate loading velocity during loading first paragraph video；First paragraph video is obtained by server from cutting on pre- setting video
Arrive.
Step 230, when first paragraph video to preset length is played, according to the residue length of first paragraph video
And the loading velocity of first paragraph video, calculate the length of the second segment video for treating to load to server request.
Step 240, the length of second segment video and the product of the coefficient of default expression network condition are made
It is the length of new second segment video.Understood with reference to foregoing embodiment, if the second segment for calculating is regarded
The length of frequency is 40 seconds, now considers further that some other unstable networks factors, and one is multiplied by the length
Coefficient, such as 80%, then the time span of second segment video is 40 × 0.8=32, then second segment is regarded
The url of frequency is www.videourl.com/12345St=20＆et=52.
Identically with previous embodiment, when new video is loaded in the loading velocity according to second segment video,
When second segment video playback to this section the 50% of video, the 3rd section of video length that being calculated to load is
4.7 × 32 × 0.5 × 0.8=60, the length of such 3rd section of video is 60 seconds, and starting position is 20+32=52,
End position is 52+60=112, and the url of request is www.videourl.com/12345St=52＆et=112.
Step 250, when the length of second segment video is less than default first length, by the length of second segment video
Degree is revised as default first length.According to the technical scheme of the present embodiment, if the network speed of certain user is non-
The possible very little of the second segment video length that will be loaded that is often slow, calculating, so in order to reduce service
The pressure of device, when length is loaded less than certain value, it should take another larger fixed value.For example it is every
Secondary loading length can not be less than 10 seconds, if the loading length calculated is for 8 seconds, it is necessary to use 10
Second is loaded.
Step 260, between the end time according to first paragraph video is set at the beginning of second segment video, according to
The end time of first paragraph video sets the end time of second segment video with the length of second segment video, and
By between at the beginning of second segment video and the end time adds request to be transmitted.
Step 270, the second segment video obtained from cutting on pre- setting video that load server sends for
Play.

Seeking time and loading deadline, it is possible thereby to the temporal information according to first paragraph video is calculated loading
The short time consumption of first paragraph video.In the present embodiment, the quantity of first paragraph video can be one and also may be used
Being multiple.According to the technical scheme of the present embodiment, the principle for calculating video loading velocity is：When broadcasting
Put device user terminal and send request to obtain during video segment to server, record starts request time ts1, when
A time te1 is recorded after the completion of segmenting video loading, can obtain loading this section of video using te1-ts1
Short time consumption be t1；This section of length of video is L1, then can be obtained by obtaining L1 in t1 seconds
The video of second length, the video length for being so probably estimated that loading per second is L1/t1, if for example
The video for obtaining 20 seconds takes 5 seconds, then can be simply considered that the network speed of user each second can
Think that user obtains the video content of 4 seconds.
Video length computing module 320, when first paragraph video to preset length is played, regards according to first paragraph
Second loaded to server request is treated in the residue length of frequency and the loading velocity of first paragraph video, calculating
The length of section video.In the present embodiment, in first paragraph video display process, when video playback to should
Section video length 50% when (value can be adjusted), start load next section of video.Due to there remains
50% video is not played, if the length of first paragraph video is 20 seconds, then remaining video probably can be with
Play 10 seconds；Because the video that can probably obtain 4 seconds per second, then in ensuing reproduction time
Interior general user obtains 40 seconds videos of length.If the total length of certain video is less than end position, knot
Beam position is the position of video footage.
Request module 330, according to the length of second segment video, loading second segment video is sent to server
Request.
