Description
Technical field
The present invention relates to Internet technical field, more particularly to a kind of method and system of video file transcoding.
Background technology
Develop the universal of internet with information technology, internet will further influence the public's life on the basis of existing
Every aspect living, internet will be in the function of more aspect carrying work, life, final promotion entire society informationization water
Flat raising and culture life is enriched.By internet and the information-based life ＆ amusement pattern innovated, such as the network media, net
Network community, online game, instant messaging, search, e-commerce etc. not only efficiently easily improve the study and work effect of people
Rate, enriches the entertainment demand of people, but also has greatly pushed the development of social economy.
Internet video business is one of the Internet, applications with fastest developing speed, has merged digital technology and traditional media industry
Business, becomes the important entertainment way of people.Internet video is the IPTV or so-called wideband videos to being propagated based on Internet technology
General designation.According to the 35th time of China Internet Network Information Center (CNNIC) publication《China Internet network state of development statistics report
It accuses》, by June, 2016, Chinese Internet video userbase increases by 10,000,000 people, network video up to 5.14 hundred million, compared with the end of last year
Frequency subscriber usage is 72.4%.Wherein, mobile video userbase is 4.4 hundred million, and 35,000,000 people are increased compared with the end of last year,
Half annual growth is 8.7%.Mobile phone network video utilization rate is 67.1%, increases by 1.7 percentage points compared to the end of the year 2015.Network
Video user overall size is still increasing, and the userbase and utilization rate of mobile video still maintain growing trend, but speedup is
Obviously slow down.
2016, significant changes had occurred in China video industry.Major video website actively with each show business cooperation, is beaten
Logical related industry chain, makes the amusement ecosystem.Internet video industry shows following spy in equipment, content, business model
Point：
1), in terms of watch equipment, multi-screen trend is apparent, and mobile phone terminal is had an effect with smart television multiple spot.On the one hand, Internet video
User constantly migrates to mobile phone terminal, and 85.7% video user is distributed in mobile phone terminal, and mobile phone end subscriber growth rate is apparently higher than
Whole, the flow of major video website mobile terminal accounts for 70% or so of whole flow, and Mobile phone screen becomes personal network's Video service
In a most important screen；On the other hand, popularizing with smart television, 21.1% Chinese netizen is surfed the Internet using TV, and is in
Ascendant trend year by year, this has opened up new space for the growth of video user.Future, VR equipment will also become video producer contention
Another hardware entrance.
2), in terms of video content, competition of major video website in copyright purchase eases up, and makes content by oneself towards fine work
Change, differentiation direction is developed.As Internet video industrial chain is ripe, major video platform all set foot in substantially upstream channel research and development with
It makes, specialized running has been obviously improved the level of self-control content.Each major video platform self-control number of programs is caught up at present
The gesture of super copyright purchase.On the one hand major video website keeps the investment to super IP, pure net variety show, on the other hand
The Contents Construction to the vertical field such as sport, finance and economics, caricature, music is increased, the content platform of differentiation is made.
3), in terms of business model, premium content pushes user charges custom further to form, and video user increment consumption is latent
Power growth space is larger.From 2015, under the drive of many factors, video website paying customer's quantity increased sharply, meeting
Accounting of member's income in integrally taking in increases.Currently, major video website mainly passes through the differentiation layout side of the popular directory
Formula attracts user charges, following excavated to the depth restriction and demand of member user based on big data, can explore more
Increment consumption pattern.In addition, the direct broadcast band of video website/live streaming product, the prosperity from channel, can all drive value-added service mould
Formula develops, and enriches video platform revenue source.
But with the fast development of network video service, to the management of Internet video, more stringent requirements are proposed, video
Content needs are converted between a variety of file formats can just meet the needs of different application environment.Video format is converted,
Since operand is big, occupancy resource is serious, scheduling and distribution to resource bring challenge.When existing video format conversion,
When there is a situation where transcoding mistake or it is interim interrupt, need from the beginning to be calculated and converted again, cause resource and time
Waste.
