Using video compression algorithm, compressed encoding is carried out to the target video, obtains dynamic previewing video flowing, so that dynamic
The bit rate output of state preview video stream is no more than default code rate.For example, can by video compression algorithm as H.264, H.265,
VP9 algorithm compresses the image data of target video, then carries out at video re-encoding to compressed image data again
Reason turns down the code rate of output video, so that the bit rate output of image data is no more than default code rate, (such as to can be 100kbs every
Second etc.), above-mentioned dynamic previewing video is finally obtained again.In this way, dynamic previewing video can be reduced further
Data volume, so that user during checking, can save bandwidth resources, the user experience is improved.When obtaining dynamic previewing

Look at processing method further include: by described when dynamic previewing video is sent to content distribution system, so that the content distribution system
The first uniform resource locator checked for user is generated according to the winter preview video.
In this example embodiment, with continued reference to shown in Fig. 2, after obtaining above-mentioned dynamic previewing video video_2,
Dynamic previewing video video_2 is sent to CDN (Content Delivery Network, i.e. content by processing system for video 201
Dissemination system) in server 203, after CDN server 203 receives dynamic previewing video video_2, generation can be with
Corresponding first uniform resource locator of the dynamic previewing video.Wherein, user can pass through first uniform resource locator
Directly dynamic previewing video video_2 is checked.
Further, first unified resource positioning directly can be found by the way that window is broadcast live for the ease of user
Symbol, refering to what is shown in Fig. 3, the dynamic previewing processing method of the live content can also include step S310 and step S320.Its

Its corresponding live video original video stream address URL 1 is obtained further according to the unique identifier ID of each live streaming, finally by
The video distribution function that CDN server 203 provides can obtain the original video stream video_1 of live streaming from URL1.
It is corresponding to download URL1 by network, and is handled original video stream video_1 by step S20
Video flowing video_2 afterwards.Specific processing step is as follows:
A is decoded processing to each frame video of original video stream video_1, obtains the image data of each frame of video；
B samples the image data decoded in time, and carries out frame losing processing to sampled result, regardless of former
How is video frame rate, and per second saves a small amount of video image data, such as 5 frame per second after processing；
C, to sampling in frame losing treated image data space, the resolution ratio of scaled down image (avoids figure
Image distortion causes information transmitting mistake), the resolution ratio of image is such as sampled as most wide 480 pixels of highest；
D, with video compression algorithm as H.264, H.265, VP9 algorithm, the image data after resolution decreasing is regarded
Frequency re-encoding process turns down the code rate of output video, as 100kbs is per second；
E carries out silence processing to original stream audio；
F merges the video handled well and audio data, generates current video stream video_2.
Video_2 is forwarded to CDN server 203 by network by step S30, and the generation of CDN server 203 can be for visitor
The video flowing of family end viewing watches address URL 2；Then URL2 is sent to processing system for video 201 again.
The video flowing URL2 handled well is reported to database 202 by step S40, processing system for video 201, then again and often
The unique identifier ID of a live streaming is bound.
