The specific embodiment of each step in embodiment illustrated in fig. 1 is described in detail below.
Firstly, in step s 110, video data stream can be sent to receiving end.
In the exemplary embodiment, receiving end may include multiple client, such as cell phone client, computer client etc.
Deng.When receiving Video service, video data stream can be sended over constantly to receiving end for receiving end, to meet receiving end pair
The demand of real-time video services.It include multiple image in video data stream, it can be by real-time collected view by network transmission
Frequency frame is sent to receiving end, and receiving end can play the frame video image after receiving.In the exemplary embodiment, it is sending
When video data, video data can be encoded, transmit occupied resource to reduce data, improve transmission rate.
Specifically, Fig. 2 shows the flow charts that video data stream is sent to receiving end.With reference to Fig. 2, this method comprises: step
Rapid S201 carries out coding to video data not sent in the video data stream and exports multiple data packets；And step
The receiving end S202, Xiang Suoshu successively sends the data packet.
In step s 201, first video data can be encoded when video data is sent to receiving end, will be adopted
The corresponding data packet of the available video frame after the coding video frames collected, so that receiving end is receiving the data
Bao Shi is decoded the data packet to obtain the frame video image.It illustratively, can be using H.264 video coding and decoding technology
Video data is encoded, multiple data packets of available video data after coding.Similarly, receiving end is receiving number
The data packet can be decoded using H.264 technology according to after packet, to obtain the video data for including in the data packet.And
And when being encoded to video data can also use other coding techniques, such as JPEG coding, H.261 coding etc..
In step S202, data packet can be successively sent to by receiving end according to the sequence that data packet generates.It is exemplary
Ground when needing to be sent to receiving end if there is video, can carry out the image data of acquisition when collecting first frame image
Coding, then export the data packet of the frame image, the data packet be then sent to receiving end, next to the second frame image into
Second data packet is sent to receiving end by row coding, successively handles each frame image during real-time video, to guarantee to connect
The video playing of receiving end is clear.
Then, in the step s 120, feedback report of the available receiving end to the video data sent.
In exemplary embodiment, after sending video data stream to receiving end, receiving end can receive the video
A part of video data sent in data flow, therefore feedback report may include reception feelings of the receiving end to video data
Condition.Specifically, may include in feedback report receiving end the received data packet of identification information and receiving end letter
Breath, such as quantity, the mark of data packet of received data packet are good etc..In addition, feedback report can also include other letters
Breath, such as receive the temporal information of data packet, the size of data packet etc., this example embodiment does not do particular determination to this.
Data can be obtained from receiving end by metadata acquisition tool, receiving end can acquire demand according to data and generate instead
Feedback report.For example, the frequency acquisition of data is arranged by agent program, the data of acquisition are generated into feedback according to frequency acquisition
Report is back to server-side, or feedback report etc. is returned when receiving request.Further, it is also possible to obtain by other means
Feedback report, such as the reception condition of video data will be collected at regular intervals by receiving end, form feedback
Report is uploaded to server-side automatically, for server-side inquiry etc..
Next, in step s 130, the transmission rate of not sent video data can be adjusted according to feedback report.
In exemplary embodiment, can analyze current network transmission state according to feedback report, if network transmission compared with
The transmission rate of video data can suitably be increased well；If network transmission badly if reduce the transmission rate of video data.Example
Such as, if analyzed according to feedback report, current transmission time delay is longer, shake is larger, transmission rate can be reduced, be made
Obtaining transmission rate being capable of adaptation network situation.In this exemplary embodiment, transmission rate can be according to receiving end to having sent
The feedback of video data, is continuously adjusted, so that the transmission rate of video data balances each other with network condition, in turn
The problem of video flower screen can be effectively improved.
Finally, in step S140, according to the transmission rate of video data adjusted by not sent video data transmitting
It send to receiving end, so that receiving end plays video.
In this exemplary embodiment, not sent video data is sent according to the transmission rate of adjustment, and in transmission
In the process, not sent video data is constantly adjusted according to the feedback of receiving end, until by owning in video data stream
Data transmission terminate.After receiving end receives video data, the packet sequence of the multiple data packets received can be adjusted
Packet serial number that is whole, generating when being sent according to video data, data packet is arranged in sequence, random ordering is avoided to cause video playing
Mistake.
Fig. 3 shows a kind of scene that the transmission rate of not sent video data is adjusted according to feedback report.With reference to Fig. 3,
This method comprises:
Step S301 calculates the receiving end for the packet loss of the video data sent according to the feedback report
Rate；And step S302, reduce the transmission speed of the not sent video data if the packet loss is more than preset threshold
Rate.
Illustratively, receiving end can be calculated for having sent the packet loss of video data according to feedback report.For example,
In one time cycle, sum of giving out a contract for a project is S, and obtaining the received data packet sum in receiving end by feedback report is R, then
Packet loss P is 1-S/R.When packet loss is calculated, by packet loss compared with preset packet loss threshold value, if packet loss is more than
Preset threshold, then packet loss can be requested to retransmit, and reduces transmission rate.If packet loss is not above preset threshold, that
Packet loss can be requested to retransmit, then detect the packet loss of next time cycle.Wherein, transmission rate can be according to packet loss
It is calculated, such as sets and wrap sending time that the data packet of a length of Len occupies as t, packet loss is calculated as P, then can be with
Sending time is adjusted to t* (1+P).The sending time for increasing data packet can reduce transmission rate, to reduce network transmission
Pressure, improve packet loss caused by receiving end video flower screen the problem of.
Fig. 4 shows another scene that the transmission rate of not sent video data is adjusted according to feedback report.With reference to figure
4, this method comprises:
Step S401 determines the propagation delay time of the video data sent according to the feedback report；And step
S402 calculates the not sent video data according to the propagation delay time if the propagation delay time is more than preset threshold
Transmission rate.
Illustratively, the propagation delay time of the data packet sent can be determined according to feedback report.Propagation delay time can lead to
The time and receiving end for crossing data packet transmission receive the time difference between the time of the data packet to indicate.When calculating transmission
It delays, can determine whether the propagation delay time is more than preset threshold.Wherein, preset threshold may be set according to actual conditions, example
Such as 0.1s, 0.2s, also, calculate each data packet send and receive between when delay to calculate and sent data
The average delay of packet, can be using average delay as the preset threshold of propagation delay time.In addition, preset threshold can also be other
Value, for example, the time delay of current data packet and the ratio of average delay etc., this example embodiment does not do particular determination to this.Such as
The time delay that fruit has currently sent data packet is more than preset threshold, then can be worked as according to the time-delay calculation for currently having sent data packet
Preceding transmission rate, so that transmission rate can be adjusted in real time according to the transmission situation of data packet.For example, it is one long to set transmission
It is t that degree, which is the time needed for the data packet of Len, and current time delay is rtt, average delay Rtt, then can will be adjusted to the time
T*rtt/Rtt, if current transmission time delay is greater than mean transit delay, the time adjusted is compared to the time before adjustment
It will increase, that is to say, that when current time delay increases, reduce the transmission rate of data packet, and then delay variation can be improved and caused
Video flower screen the problem of.
In the exemplary embodiment, after the packet loss for having sent video data is calculated according to feedback report, if should
Packet loss is more than preset threshold, can be recompiled to not sent video data.Specifically, can coding when, to
It forces to send coded frame in receiving end.The coded frame can be used for refreshing the video image of receiving end, by the reference frame sequence of receiving end
Column empty, that is, so that receiving end since the coded frame not referring again to pervious frame, by the video image of receiving end and server-side
It synchronizes, improves because the video caused by packet loss is excessive spends the problem of shielding.In addition it is also possible to by adjusting coding output
The problem of rate exports to reduce coding, and then slows down the rate of data transmission, and balance network transmission is deteriorated is reduced data and is gathered around
Plug.
When illustratively, using H.264 encoding, relative to every IDR frame, the subsequent each reference frame of the frame is required in decoding
Image could be correctly parsed with reference to the frame of the front.Therefore it can be exported when packet loss is more than preset threshold with forced coding
Every IDR frame plays video in order to empty the reference frame sequence of receiving end since the every IDR frame.
Thus, it can also be including step S501 to step according to the transmission rate that feedback report adjusts not sent video data
S504, as shown in Figure 5.Wherein:
Step S501 determines the propagation delay time of the video data sent according to the feedback report；Step S502,
Determine the reading rate for calculating video data stream when the propagation delay time is more than preset threshold according to the propagation delay time；Step
S503 reads the not sent video data in the video data stream according to the reading rate of the video data；Step S504,
Coding output data packet is carried out to the video data read.
With reference to Fig. 5, after the propagation delay time that the video data sent is determined according to feedback report, if the propagation delay time is super
Preset threshold is crossed, then the reading rate of video data stream can be calculated according to the propagation delay time.For example, the biography of current data packet
Defeated time delay is L, and preset threshold 1, the reading rate of video data stream is V, then when L is greater than 1, video data adjusted
The reading rate of stream can be V/L.Then, video is read according to the reading rate when encoding to not sent video data
Data flow can reduce the output speed of data packet to carry out coding output data packet to the video data read, adaptation
Network condition.That is, network transmission shake is larger when propagation delay time is larger, video data stream can be read at this time
Rate reduces, to reduce encoding rate, reduces coding output, improves Huaping phenomenon caused by changing because of network.
In optional embodiment, receiving end can be sent for video data based on User Datagram Protocol.In addition, can also
To utilize other transport protocol transmitting video datas, such as Transmission Control Protocol etc..
