Moving scene information etc., wherein moving scene information can be the generation of the scenes such as scene information, explosion when human or animal runs
The scene information of acute variation；The preset requirement can be face facial image information, for example, each ts of server analysis points
Piece is to belong to any in characteristic information, and is classified to each ts；When preset requirement is people's face facial image information,
Those ts fragments that can embody face facial image information are ranked up by server according to chronological order, are regenerated
Video frequency abstract, while the identification information of each ts of composition video frequency abstract is recorded, when the file name that identification information is ts fragment
When, identification information is, for example, 10.ts, 60.ts, 140.ts, 343.ts ...；Then, by video frequency abstract and video content
M3u8 file is integrated, and when terminal plays video, directly can obtain video content, therefore video frequency abstract according to index file
Video content do not need extra storage.
Here, the video frequency abstract refers to the interested video clip of user according to feature information extraction, the step
101 can also be realized using conventional video abstraction generating method in the art, therefore be repeated no more.
Step 102, server record for generate each ts fragment in the video frequency abstract identification information and
Sequentially；
Here, the identification information of the ts fragment can be the title (filename), the serial number of ts fragment, number of ts fragment
Etc. information.
Here, the sequence can refer to the sequence using temporal information as representative, for example, a total of the 100 of one section of video
A ts fragment, it is 001 to 100 that this 100 fragments, which are in chronological sequence sequentially numbered,；Wherein, the number of ts fragment be 003,
008 and 058 composition video frequency abstract, then the sequence of the ts fragment in video frequency abstract described here refers to 003,008 and 058.
Step 103, the server obtains the address URL of each ts fragment in the video frequency abstract；
Here, the address URL of each ts fragment refers to that original video divides the address URL of rear ts fragment.
Step 104, the server generates the level-one m3u8 file of the video frequency abstract；
Step 105, the server is according to the address URL of each ts fragment in the video frequency abstract, the mark of ts fragment
Know information and sequence, generates second level m3u8 file corresponding with the level-one m3u8 file.
In general, video is stored in the form of ts fragment, under normal circumstances, the duration of ts fragment is provided according to HLS protocol
It can be 10 seconds, m3u8 file is at least used to describe the address URL of ts fragment, wherein level-one m3u8 file relates generally to two
Parameter, wherein first parameter is code rate, second parameter is URL address information corresponding with each code rate parameter；Second level
M3u8 file is related to a parameter i.e. URL address parameter；
Terminal first obtains index file, then obtains ts fragment.Specifically, terminal first obtains level-one m3u8 file, according to certainly
Body bandwidth situation selects a kind of suitable code stream to play out, i.e., the identification information of level-one m3u8 file is sent service by terminal
Corresponding second level m3u8 file will be sent to terminal, such terminal according to the identification information of level-one m3u8 file by device, server
Ts fragment can be downloaded according to the address URL in second level m3u8 file, and is carried out according to the sequencing in second level m3u8 file
It plays.
Here is the level-one m3u8 file and second level m3u8 file example of video content:
Level-one m3u8 file: example index.m3u8
BANDWIDTH=1280000bps, URL11/low.m3u8；
BANDWIDTH=2560000bps, URL12/mid.m3u8；
BANDWIDTH=7680000bps, URL13/hi.m3u8；
By taking second level m3u8 file mid.m3u8 as an example, the content in mid.m3u8 is as follows:
URL12/01.ts；
URL12/02.ts；
URL12/03.ts；
URL12/04.ts；
URL12/05.ts；
URL12/06.ts；
……；
In above-mentioned example, the unit of bandwidth (BANDWIDTH) is bit/second (bps, bits per second), wherein URL
URL11, URL12 and URL13 in address can indicate the same address URL, can also indicate the different address URL, URL
" low.m3u8 ", " mid.m3u8 ", " hi.m3u8 " in location respectively indicate filename.
A kind of video frequency abstract processing method based on HLS protocol is proposed in the present embodiment, server first draws video main body
It is divided into video data ts fragment, analyzes the characteristic information of each ts fragment, the ts of preset requirement is met according to the characteristic information
Fragment generates video frequency abstract；Then, the identification information and sequence for generating each ts fragment in the video frequency abstract are recorded；
The address URL of each ts fragment in the video frequency abstract is obtained again；Then the level-one m3u8 file of the video frequency abstract is generated,
Finally according to the address URL of each ts fragment in the video frequency abstract, the identification information and sequence of ts fragment, generate with it is described
The corresponding second level m3u8 file of level-one m3u8 file；In this way, first playing wonderful when terminal plays internet television video
Video frequency abstract after video frequency abstract finishes, then plays in entire video to user with the general preview of the video content
Hold, to improve the experience that user watches internet television.
Two kinds of methods for realizing the level-one m3u8 file for generating the video frequency abstract, both methods is provided below
In do not need independently of video main body carry out individually storage video frequency abstract, wherein
First method are as follows:
In the embodiment of the present invention, the server generates the level-one m3u8 file of the video frequency abstract, comprising:
The server obtains the level-one m3u8 file of video main body, as the video frequency abstract with different code rates
Level-one m3u8 file；
Accordingly, the server is according to the address URL of each ts fragment in the video frequency abstract, the mark of ts fragment
Information and sequence generate second level m3u8 file corresponding with the level-one m3u8 file, comprising:
The server is by the address URL of each ts fragment in the video frequency abstract, the identification information of ts fragment and suitable
The front of second level m3u8 file corresponding with the level-one m3u8 file of the video main body is written, so that terminal is being requested in sequence
Video frequency abstract is first got when video main body.
Second method are as follows:
The server generates the level-one m3u8 file of the video frequency abstract, comprising:
The server generates the level-one m3u8 file of the video frequency abstract according to the code rate information of video main body.
In first method and level-one m3u8 file about video frequency abstract is not independently generated, but directlys adopt video master
The level-one m3u8 file of body, i.e., write direct the ts burst information of video frequency abstract in the m3u8 file of video content, wherein regarding
The level-one m3u8 file of frequency content is constant, before video content in the ts burst information write-in second level m3u8 file of video frequency abstract
Face.Here, ts burst information mainly includes the address URL of each fragment, identification information such as title of ts fragment etc..Here is
The level-one m3u8 file of video frequency abstract and the example of second level m3u8 file in a kind of method；
The level-one m3u8 file of video frequency abstract, i.e. the level-one m3u8 file of video main body, example index.m3u8:
BANDWIDTH=1280000bps, URL11/low.m3u8；
BANDWIDTH=2560000bps, URL12/mid.m3u8；
BANDWIDTH=7680000bps, URL13/hi.m3u8；
By taking second level m3u8 file mid.m3u8 as an example, the content in mid.m3u8 is as follows:
URL12/10.ts；
URL12/60.ts；
URL12/140.ts；
URL12/343.ts；
* * * or more is video frequency abstract, is video main body * * * * below
URL/01.ts；
URL/02.ts；
URL/03.ts；
……
In above-mentioned example, the unit of bandwidth (BANDWIDTH) is bps, wherein URL11, URL12 in the address URL and
URL13 can indicate the same address URL, can also indicate the different address URL, " low.m3u8 " in the address URL,
" mid.m3u8 ", " hi.m3u8 " state filename respectively.
In first method, since the ts burst information of video frequency abstract to be previously written to the second level m3u8 file of video main body
In, so, for the second level m3u8 file of each middle code rate, server will record the real initial position of video main body, as above
The address first four URL of the example stated, second level m3u8 file is all the ts fragment address of video frequency abstract, from the 5th address URL
Start the ts fragment address for being only video main body.The real initial position for why recording video main body, this is because sometimes
User may be not intended to play video frequency abstract, at this moment just need to directly acquire video body matter, since server is recorded
The real initial position of video main body, such user can skip video frequency abstract, directly start to watch video main body.If clothes
Business device does not record the real initial position of video main body, it would be possible that cause user that can not choose whether to play video frequency abstract, this
Sample one, for user when program request plays video, first to play abstract could play video main body, alternatively, user can only be by dragging
It is dynamic just to stop playing abstract；After abstract finishes, video content is played automatically.The real starting of video main body is not recorded
This method and user interaction flow of position are few, but realize relatively easy.
In second method, the ts burst information of video frequency abstract is generated into level-one m3u8 file and second level m3u8 file, depending on
The level-one m3u8 file of frequency abstract and the level-one m3u8 file of video content are independent.Here is to be plucked in second method according to video
The ts burst information wanted generates the example of level-one m3u8 file and second level m3u8 file；
The level-one m3u8 file of video frequency abstract, example index_ad.m3u8:
BANDWIDTH=1280000bps, URL21/low_ad.m3u8；
BANDWIDTH=2560000bps, URL22/mid_ad.m3u8；
BANDWIDTH=7680000bps, URL23/hi_ad.m3u8；
By taking the second level m3u8 file mid_ad.m3u8 of video frequency abstract as an example, the content in mid.m3u8 is as follows:
URL22/10.ts；
URL22/60.ts；
URL22/140.ts；
URL22/343.ts；
Here is the level-one m3u8 file of video main body in second method, example index.m3u8:
BANDWIDTH=1280000bps, URL11/low.m3u8；
BANDWIDTH=2560000bps, URL12/mid.m3u8；
BANDWIDTH=7680000bps, URL13/hi.m3u8；
By taking the second level m3u8 file mid.m3u8 of video main body as an example, the file in second level m3u8 file mid.m3u8 is such as
Under:
URL12/01.ts
URL12/02.ts
URL12/03.ts
URL12/04.ts；
URL12/05.ts；
URL12/06.ts；
……；
In second method, although video frequency abstract and video content share ts burst information, the fragment of the two indexes text
Part (level-one m3u8 file and second level m3u8 file) is completely independent.Therefore, in the second approach, server needs to record video
The storage address of the level-one m3u8 file of the level-one m3u8 file and video main body of abstract；In video request-program process, by user
It chooses whether to play video frequency abstract, when being, then after video frequency abstract broadcasting, can directly play video main body, it can be again by user
It chooses whether to play video content, it is seen then that second method is preferable in terms of user-interaction experience.
