Parameter, it is ensured that the seriality of video playback, reduces transmission delay.Describe in detail below by specific embodiment
Should video acquisition realization method based on photographic head.
Embodiment one
The embodiment of the present invention one provides a kind of video acquisition realization method based on photographic head, and the method flow process is such as
Shown in Fig. 1, comprise the steps:
Step S101: according to the type information of each terminal unit playing Internet video, determine video acquisition
Optimum size.
Owing to Internet video is after transmission, the type of the opposite equip. receiving Internet video is the most true
Fixed, it may be possible to mobile terminal device, it is also possible to personal computer (PC), it is also possible to be panel computer
(PAD), the size that these different types of terminal units play screen is not quite similar, the chi to video playback
Very little requirement is also not quite similar, and therefore, realizes in this step according to each terminal unit playing Internet video
Type information, determines the optimum size of video acquisition, according to the type of each terminal unit playing Internet video
Information, obtains the screen size information of each terminal unit；According to getting screen size information, determine and can fit
For the video playback size of the upper broadcasting at each terminal unit, obtain the optimum size of video acquisition.
It is said that in general, optimal result is to determine that one is suitable for different types of according to each terminal unit
The optimum size play on terminal unit, carries out video acquisition according to this optimum size, such that it is able to respectively
Can well play on individual terminal unit.
Such as, the default size of camera video acquisition generally has 800*600,400*300, optimal aspect ratio
For 3:4(i.e. AspectRatio=3/4), in order to not affect other performances of browser or player, finally combine
Having closed the broadcasting dimensional requirement of different types of terminal unit, the optimum size determined (VideoSize) is
320*240, when carrying out parameter configuration, is then configured to VideoSize*Video:320*240(4/3).
Step S102: according to the network bandwidth of transmission network video, adjust the biography that Internet video is transmitted
Defeated code check.
Internet video retardance accounts for critically important factor when transmission of video is play, and keeps the network video of transmission
The broadcasting seriality of frequency is necessary, and seriality for this angle, real-time is heavier than image definition
Want.And the seriality of Internet video is affected by transmission code rate, therefore, this step realizes according to transmission
The network bandwidth of Internet video, adjusts the transmission code rate being transmitted Internet video, thus remains able to the greatest extent
The seriality of guarantee Internet video broadcasting that may be good.
Concrete, when adjusting, obtaining the network bandwidth being currently used in transmission network video, inquiry is preset
The network bandwidth and the corresponding relation of transmission code rate, obtain the transmission code rate corresponding with the network bandwidth got,
As the transmission code rate that Internet video is transmitted.
Such as, the network bandwidth preset and the corresponding relation of transmission code rate can be according to the biggest transmission of the network bandwidth
The rule that code check is the highest is preset, and during so that Netowrk tape is roomy, can improve transmission code rate, transmission
More video data, makes the result of broadcast of Internet video more, and the network bandwidth hour suitably reduces transmission
Code check, to guarantee to obtain the best video display effect in the range of bandwidth allows, and don't
Make Internet video play to occur interrupting, it is ensured that the fluency of video playback.
For example, it is possible to setting/VideoQuolity: dynamically adjust meet maximum bandwidth require/.
Step S103: according to the configuration parameter of the codec of each terminal unit, determine the volume solution of Internet video

Frequently codec, this basic-level support can preferably be compressed video, reduce bandwidth demand.Codec leads to
Certain encoding and decoding rank is often had to arrange.When Network Video Collection, it is also desirable to according to the collection being arranged above with
The parameter such as optimum size, transmission code rate, selects in the case of these parameters of guarantee meet condition as far as possible
Most suitable encoding and decoding rank.Therefore, joining of the codec according to each terminal unit is realized in this step
Put parameter, determine that the encoding and decoding of Internet video gather rank.
Concrete, according to the configuration parameter of each terminal unit codec, obtain each terminal unit codec
The encoding and decoding rank supported, selects optimum size and the encoding and decoding rank of transmission code rate supporting to be determined
Encoding and decoding as Internet video gather rank.Generally, if codec encoding and decoding rank select mistake
Low meeting causes browser or the interference of other functions of player and CPU to cross consumption, and therefore, codec is compiled and solved
The selection of code rank receives the impact of the hardware configuration of the terminal unit of user, and usual rank exists
About Level.LEVEL_3_1, is i.e. configured to/H264Level.LEVEL_3_1 during parameter configuration;/.
Step S104: according to the hardware configuration information of each terminal unit, determine the key frame of Network Video Collection
Frame frequency.
Key frame frame frequency (Frames Per Second, FPS) will affect the definition that Internet video is play,
Meanwhile, key frame frame frequency is excessive, it is also possible to cause the rising of transmission code rate, therefore, joining of key frame frame frequency
Put for ensure video playback definition be the most necessary.
The configuration of key frame frame frequency can configure according to the hardware configuration information of the terminal unit of user.
Such as, when the hardware configuration information of terminal unit includes the battery electric quantity of terminal unit, set according to each terminal
Standby hardware configuration information, determines the key frame frame frequency of Network Video Collection, specifically includes acquisition terminal unit
Battery electric quantity, the corresponding relation of battery electric quantity and key frame frame frequency that inquiry is preset, obtain and get
The key frame frame frequency that battery electric quantity is corresponding, as the key frame frame frequency of Network Video Collection.This is due to key
Frame frame frequency is the highest, the most more needs the support of more battery electric quantity, when battery electric quantity is the fewest, if transmission code
Rate configuration is too high, will directly affect laser propagation effect.
Certainly, except battery electric quantity, other hardware configuration information is likely to become and affects key frame frame frequency and join
The factor put, through practice, the best practices scope of general key frame frame frequency is 15～24.I.e. parameter configuration
Time be configured to/FPS:*FPS=20;/.
Step S105: according to the definition requirement to video playback of each terminal unit, determine Network Video Collection
Key frame mend between the quantity of key frame.
Generally after determining key frame frame frequency, between the benefit between two key frames, key frame quantity is the most,
Its definition play and seriality are the best, key frame between key frame benefit, act on non-on video optimum efficiency
Chang great.But, between the benefit of transmission, key frame is the most, and the data of required transmission are the most, therefore,
When determining key frame quantity between benefit, its quantity is excessive too small all can be had the definition of video playback and seriality
The biggest impact, too small image is at abnormal packet loss, and picture can be the fuzzyyest, and generally, optimum is 48, i.e.
/ keyFrameInterval:48/ it is configured to during parameter configuration.
Step S106: gather rank, key frame according to the optimum size determined, transmission code rate, encoding and decoding
Frame frequency and the quantity of key frame between mending, to camera collection to the relevant parameter of original video be adjusted place
