Description
Technical field
The invention belongs to ios platform technical field.
Background technology
Dancing is the artistic expression of most unique aesthetic feeling in aesthetic, can both be conveyed feelings, again can reach U.S., by when
Between rubbed up with space, show harmony the rhythm, be not only to have beautified the art of human action, even more surmounted body and soul
Beautiful appreciation;Dance education is to show artistic image by aesthetic way and subtle infect people, inspire people and education
People;To improve the dancing enjoing ability of people, it is necessary to carry out dancing universal education;Dancing universal education is mainly towards non-dancing
Major and amateurish dancing fan, them are cultivated dancing is aesthetic, the ability of dance training and basis performance etc.;Dance
Teaching is stepped using limbs and coordinates the artistic medias such as music, clothes, stage property, light, is influenceed by time and space, it is impossible to be big
Carry out to scale;By mobile learning, new thinking is provided for dancing universal education by way of net cast or relay.
The content of the invention
Live broadcast system service discovering flow scheme design:Live broadcast system service discovering flow includes three kinds, i.e., based on WAP modes
The service discovering flow of service discovering flow, the service discovering flow based on HTTP modes and SMS-Based mode;I0S recommends to make
With HTTP modes, i.e. client finds the address of live content and completes the process of live relevant supplementary information;HTTP side
Formula service discovering flow is made up of 7 steps, and each step is as follows:
(1) certification and login:Streaming medium content Portal is accessed by HTTP modes and completes authentication, in order to realize identity
The physics of certification and streaming medium content is unified, and authentication is completed by Portal;
(2) error message is returned:If certification it is unsuccessful or log in it is unsuccessful all will display error message and return HTTP login
Interface;
(3) terminal page is generated:Streaming media service platform Portal will be adapted to live in the terminal according to type of user terminal
Program classification table and the recommendation column generation page;
(4) receive and check the page:Streaming media service platform Portal sends the page to user terminal, and user is received after the page by clear
Device of looking at checks content;
(5) content information is positioned:User uses the functions such as content navigation, search and systematic searching, streaming media service platform
Portal is positioned to live specific stream media information;
(6) dynamic generation address:According to the content dynamic generation URL that user's operation is selected, except including Streaming Media address information
Outside, Portal will also add necessary content information and Hash encryption information;
(7) live process is started:User completes discovery procedure after receiving streaming media service platform Portal URL, touches or single
It can start download or live process after hitting URL connections.
Live broadcast system structure design:The time-base media data flow that Streaming Media is transmitted using streaming technology in a network,
Including voice data stream and video data stream, whole file need not be downloaded before broadcasting, but downloads play at any time at any time, is saved
System resource and period of reservation of number, implementation include HPPT, WAP and message etc.;HTTP Streaming transfer protocol bases
Realized in http protocol, by http protocol, Streaming Media be sent to iPhone from Web server, iPad, iPodtouch and
In the i0S equipment such as Apple TV and Apple computer equipped with USX, net cast and order program service are realized;Based on HLS's
I0S live broadcast systems are made up of streaming media service component, content distribution components and client three parts, and structure is as follows:
1. streaming media service component:Streaming media service component is responsible for the medium stream information coding of input to digitize post package into symbol
Family needs and the form of network transmission are shared, and are transmitted to content distribution components;Streaming media service component is by media encoders, stream
Dispenser and File Splitter are formed, and media encoders are typically hardware device, the main compression and processing for completing information;In order to
Realize preferable result of broadcast and versatility, it is desirable to which media encoders support that the video source such as HDMI, SDI, VCA, CVBS is defeated
Enter, support HDMI and SDI insertion audio inputs, support H.264-HP, the various modes such as BP coding and high standard definition coding, coding prolong
When be less than 200ms;Flow splitter be by audio video file be divided into " ts " be suffix small pieces segment file one by one, without
Recompiling can just play;During live, media encoders are constantly be generated data, and flow splitter is constantly divided into
Small documents one by one, the file size of segmentation are set dynamically by system, typically 10s or so;What content server component received
Input can also be the files in stream media of precoding, at this moment just need File Splitter to be divided into " ts " is the small of suffix
Clip file, which is realized, to be played;
2. content distribution components:Content distribution components can be the Web server of standard, receive client request, prepare in advance
Good media data and related resource are live for client downloads;Hold distribution of document and manage two class files, one kind is by flow splitter
Or File Splitter segmentation with " ts " be suffix small pieces segment file, it is another kind of be for " ts " files are managed and generate
Index file;" ts " files are the Document encapsulation form for following MPEC -2 standards, M PE C-2 are that MPEC is organized to set up
One of video and audio lossy compression method standard, it is referred to as " compression standard based on digital storage media moving image and voice ", is
For the compression scheme of Standard Digital Television and high definition television under various applications, have compared with MPEC-1 standards higher
Picture quality, more picture formats and transmission code rate;Index file uses m3u8 file format specifications, is mainly opened including file
Begin mark, media sequence number, the approximate time of next media file, each section " duration and URL addresses, file of ts " files
End mark etc.;When completing live, index file needs to upgrade in time;
3. client:Client is equipped with the hardware device of i0S systems, is operated according to user, using http protocol to Web service
The content distribution components of device are filed a request, and it is live to realize to download streaming media resource;Client is accessed in Web server first
M3u8 index files, parsing identification each " information such as ts " files and decruption key;Then rope is downloaded in order
In quotation part " ts " media files, each continuous " this is tardily played without pause and continuously between ts " segmental files
A little files;Client is filed a request using http protocol to Web server;In addition, client should also have processing external transactions
Function, i.e., during Dancing Teaching is live, such as occur incoming call, short message, QQ information, wechat external event, client
End will correctly be handled in time, to ensure being normally carried out for dancing live broadcast teaching.
Live broadcast system is realized:
1.HLS logic flows:By taking net cast as an example, basic process is to be separately turned on audio ＆ video coding thread, is passed through
DirectShow technologies realize audio-video collection, then call that lihx264 and lihfaac carries out video and audio is compiled respectively
Code;After two coding thread real-time coding audio, video datas, according to customized stripping strategy, some MPEC-TS lattice is stored in
In formula segmental file, after the storage of one segmental file of completion, m3u8 index files are updated;
2.HLS classes are realized:Wherein CHLSServer, carry out Socket and intercept, management gained client HLS requests;
CHLSCIient, HTTP request response is realized, according to the HLS contents of client request, gives CHLSSource processing;
CHLSSourceManager, all HLS source managers, HLS sources can be local file or carry out automatic network or set
Standby real time data source;CHLSSource, specific HLS requests are realized, include the acquisition of m3u8 file acquisitions and TS fragments.
