Specific embodiment
Invention is further described in detail with following embodiment with reference to the accompanying drawing.
Embodiment 1
As shown in Figure 1, the embodiment of the present invention 1 provides a kind of control method of buffered play Streaming Media, the controlling party
Method the following steps are included:
After program operation, user, which is sent by streaming media playing terminal to the multimedia message server 1, wants viewing
Video request；
The playing request for streaming media video that S1,1 receiving stream media playback terminal of multimedia message server issue；
And streaming media playback terminal carries out identification certification, is judged according to the end message of streaming media playing terminal, if by recognizing
Card then receives request, does not receive if not passing through.
S2, the multimedia message server 1 are suitable according to play time by several video frames in the streaming media video
It is several flow media data packets that sequence, which carries out cutting post package, several are separately included in each flow media data packet according to broadcasting
Put the video frame of time sequencing sequence；Flow media data packet is equivalent to the video clip containing several video frames, data transmission
One or more packets carry out data transmission in the process.
S3, buffer pool for caching the streaming media video is established, the multimedia message server 1 is by the stream matchmaker
Volume data packet is according to play time order buffer to the buffer pool；Buffer pool can be used to store that treated buffered data,
It ensure that viewing effect of user in the case where suspension.
S4, the flow media data packet in the buffer pool is broadcast according to play time sequential delivery to the Streaming Media
Terminal is put, while saving to described and having sent pond, the transmission time of each flow media data packet is recorded in transmission process；Institute
Stating transmission time is to have sent the timing node that pond receives the flow media data packet, and each data packet has the when segmentum intercalaris of oneself
Point.
When first time data packet is transmitted, first determine whether to have sent whether pond has flow media data packet, if not having, by institute
The flow media data packet stated in buffer pool is successively transferred to streaming media playing terminal according to crawl time sequencing, caches simultaneously
To pond has been sent, flow media data packet, then be directly entered in step S5~S7 if it exists.
S5, the current network speed for determining the streaming media playing terminal have been sent in pond according to the current network speed described
The default time threshold and data packet threshold values for saving the flow media data packet, the data packet threshold values are in the time threshold
Data packet sum；Due to network speed difference, the amount that can be transmitted is also different, in order to guarantee video in the feelings of network speed shakiness
Do not occur the phenomenon that Caton under condition, data packet threshold values is set according to network speed.
The transmission time and current time of the flow media data packet saved in pond have been sent described in S6, judgement
Whether difference exceeds the time threshold, and the flow media data packet that will exceed the time threshold is deleted；It has ensured that
Sending the flow media data packet in pond is the data packet in time threshold and current time frame, as the circulation of system is transported
Row, has sent the flow media data packet in pond in real-time change.The transmission time has as sent pond receiving stream media number
According to the timing node of packet, i.e., the difference between the timing node and current time is compared with time threshold.
The size of the quantity of the flow media data packet and the data packet threshold values in pond has been sent described in S7, comparison, if
The quantity of the bit stream data packet is greater than or equal to the data packet threshold values, then stops the data transmission in step S4, conversely, if
The quantity of the flow media data packet is less than the data packet threshold values, then enters step and continue to carry out data transmission in S4.
Method provided by the invention, which passes through buffer pool and sent pond, can effectively control the output of flow media data packet, make
Data output smoothing, the case where not will cause video cardton or frame losing generation effectively provide user's video effect of viewing.
Embodiment 2
The embodiment of the present invention 2 further defines on the basis of embodiment 1, in the range of the time threshold, institute
When stating the quantity of the received flow media data packet in buffer pool less than the data packet threshold values, in step S4, described in reduction
The flow media data packet in buffer pool is to the streaming media playing terminal and the transmission rate for having sent pond.In order to prevent
There is Caton in playing process in multimedia video, it should adjust transmission rate according to the network speed moment.
As shown in Fig. 2, needing further exist for explanation, in step S5, the current network speed of the streaming media playing terminal is determined,
Specific method includes:
1., continuous several times acquisition user's history foradownloaded video when download speed, and establish network speed list and recorded；It is logical
It crosses and acquires multiple history download speed, be capable of forming network speed record storehouse, history download speed needs to record the network speed of different moments.
2., the download speed recorded in the network speed list calculated into its average value obtain history network speed；It will be same
History network speed averagely can be obtained in the multiple network speed value at moment, as current network speed.
3., using the history network speed being calculated as the current network speed of presently described streaming media playing terminal.
By the determination of current network speed, transmission rate can be effectively controlled.
As shown in Figure 3, it should be noted that in step S5, preset according to the current network speed in described sent in pond
The data packet threshold values of the flow media data packet is saved, specific method includes:
1., in described sent network speed section from low to high is preset in pond, and corresponding data from low to high are set
Packet threshold values；
2., judge network speed section belonging to the current network speed of the streaming media playing terminal, and by the network speed section
The corresponding data packet threshold values is as the data packet threshold values sent in pond.
Data packet threshold values is determined by current network speed, when network speed is lower, can turn down data packet threshold values, when network speed is higher
When, data packet threshold values can be turned up, data are slowly exported with network speed, effectively video are avoided the phenomenon that Caton occur.
