Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
Determined whether in the prior art according to play position and the document misregistration difference of download location using under CDN node
It carries data and will lead to high bit-rate video play time for the difference standard that the file of the video of different code rates is not unified
Without switching CDN polishing data in time when close with download time point, to cause to play Caton, low bit-rate video is caused to play
When it is excessive use CDN, increase bandwidth cost.Therefore, in this application, by calculating download location time point and play position
The difference at time point, it is determined whether CDN node downloading data is used, various bit-rate videos are suitable for, it is bad in CDN node quality
In the case where, the mode supplementary data of sufficient time switchback CDN, and use CDN downloading data few as far as possible are reserved, is saved
Cost.
The embodiment of the present application discloses a kind of video file transfer method, under the premise of each bit-rate video smooth playing,
Reduce CDN bandwidth cost.
Referring to Fig. 1, a kind of flow chart of video file transfer method disclosed in the embodiment of the present application, as shown in Figure 1, packet
It includes:
S101: from the head file of CDN source server to download video files；
When receive video file after line playing request, the head of the video file is downloaded from CDN source server first
Portion's file.The video file can be specially MP4 video file, and MP4 video file is broadly divided into video head and video data
Two parts.Wherein, video head includes the corresponding relationship of key frame of video and document misregistration, therefore can be with using head file
Converse the corresponding video file play time of any offset of file.
S102: the video data of the video file is downloaded using the CDN source server；
In specific implementation, after obtaining head file, institute is downloaded using CDN source server according to the head file
State the video data of video file.Since the downloading of CDN source server is more stable, and rate is very fast, therefore can guarantee to play
Device starts to play the video file in time.
S103: the time difference of current download time point and current play time point is calculated according to the head file；
In real time, or every the preset time cycle time difference of download time point and play time is calculated.Herein
Download time point is current download location corresponding time point, can be obtained according to the head file of video file, when broadcasting
Between point i.e. current play position corresponding time point.
The length of the time difference that is to say that the equipment for playing video has been downloaded but the video file not played can also be broadcast
The duration put.
S104: the video file is downloaded using the CDN source server and/or CDN node according to the time difference
Video data.
In specific implementation, the mode for downloading the video file is determined according to the time difference that previous step is calculated, i.e.,
Using the downloading of CDN source server, using CDN node downloading, by CDN source server and CDN node mix in the way of download.Benefit
It is fast with CDN source server foradownloaded video data speed, it can satisfy the urgent need of video data, it can using CDN node downloading
To reduce the bandwidth occupancy of CDN.
Specifically, continuing with the CDN source server downloading when the time difference being less than or equal to the first preset value
The video data of the video file；When the time difference is greater than first preset value and is less than or equal to the second preset value
When, the video data of the video file is downloaded using the CDN source server and CDN node mixing；When the time
When difference is greater than second preset value, the video data of the video file is downloaded using the CDN node.
Cause stored memory excessive to avoid being cached more video datas as a preferred implementation manner, when having delayed
When depositing sufficient data broadcasting being provided, stop downloading, the time difference of time point and download time point to be played becomes smaller, further according to when
Between difference be downloaded using corresponding mode.Specifically, when the time difference is greater than second preset value and is less than or equal to
When third preset value, the video data of the video file is downloaded using the CDN node；It is greater than described the when the time difference
When three preset values, stop downloading.
That is, referring to fig. 2, above-mentioned S104 may include:
S104A: judging whether the time difference is greater than the first preset value, if it is, executing S104B, otherwise executes
S102；
S104B: the video data is downloaded using the CDN source server and CDN node mixing；
S104C: judging whether the time difference is greater than the second preset value, if it is, executing S104D, otherwise executes
S104B；
It is understood that do not limited specifically the first preset value and the second preset value herein, it need to only guarantee second
Preset value is greater than the first preset value.
S104D: the video data is downloaded using the CDN node.
Preferably, can also include: later referring to Fig. 3, S104D
S104E: judging whether the time difference is greater than third preset value, if it is S104F is executed, otherwise executes S104D；
S104F: stop downloading, and reenter S103；
It is understood that do not limited specifically third preset value equally herein, only it need to guarantee that third preset value is big
In the second preset value.For example, the first preset value can be, but not limited to be set as 2s, the second preset value can with but it is unlimited
In being set as 5s, third preset value can singly be not limited to be set as 60s.
Video file transfer method provided by the embodiments of the present application, when by calculating download location time point and play position
Between the difference put, it is determined whether CDN node downloading data is used, in the case where CDN node quality is bad, when reserving sufficient
Between switchback CDN mode supplementary data, it is smooth to ensure that each bit-rate video plays.And few as far as possible uses CDN downloading data,
Reduce CDN bandwidth, save the cost.
The concrete application embodiment of video file transfer method provided by the present application is described below.The present embodiment passes through calculating
The online request downloading process of one MP4 file is divided into 4 stages, such as by the time difference of download time point and play time
Shown in Fig. 4:
It is CDN PHASE when the time difference being less than or equal to 2s, only uses CDN source server downloading data in this section.By
It can only be obtained from CDN source server in the head file of MP4 file, after getting the head MP4, continue with CDN source server
Foradownloaded video data, it is ensured that the smooth not Caton of broadcasting.After player starts broadcasting, when determining downloading according to head file
Between point, enter next stage when the time difference for downloading time point and play time being greater than 2s.
Being greater than when 2s is less than or equal to 5s when the time difference is CDN Peer PHASE, in this section using CDN source server with
Peer (CDN node) mixes foradownloaded video data, not only ensure that video playing was smooth but also reduces CDN source server to a certain extent
Bandwidth pressure.
Being greater than when 5s is less than or equal to 60s when the time difference is Peer PHASE, and the demand of video data is not urgent in this section,
Peer downloading data can be used only, save CDN bandwidth.
It is Stop PHASE when the time difference being greater than 60s, this section stops data downloading, has sufficient data at this time and mentions
For playing, to avoid stored memory excessive, therefore stopping downloading, the time difference of time point and download time point to be played becomes smaller,
Restart foradownloaded video data into the corresponding stage.
