Abstract
The invention discloses a video direct broadcast image processing method and system; the method comprises the following steps: receiving a user request and starting video direct broadcast; obtaining network state of a terminal at a preset time interval; outputting a video stream. When the network state is good, direct broadcast signal flow output is carried out, and buffer memory is stored; when the network state is bad, the buffer memory is obtained and outputted for repeat playing, and the direct broadcast signal can be switched to when the network state become good again, thus ensuring the user not to feel bored while waiting for buffer memory; in addition, the pre-stored buffer memory can be viewed so as to reduce data flow usage.
Description
Technical field
The present invention relates to image processing field, particularly relate to net cast image processing method and system.
Background technology
In prior art, when watching video live broadcast, net cast to the network bandwidth and stability requirement higher, at mobile phone video living broadcast programs, the instability of network signal is the factor had the greatest impact to direct effect.Often can cause direct picture buffering overlong time, buffering number of times is too much.Sometimes even stuckly cannot to play.This reason is that the requirement of video code flow ground bandwidth is higher, if network signal is unstable, bandwidth is in change exactly, has Time Bandwidth very low, cannot meet the transmission of large-capacity video data.Within the time of pending buffer, user is occupied with nothing.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide net cast image processing method and system, be intended to solve prior art net cast buffer time mistake, the problem of period of reservation of number waste.
Technical scheme of the present invention is as follows:
A kind of net cast image processing method, wherein, comprises step:
The request of A, reception user, opens live video;
B, obtain the network state of user terminal every Preset Time;
C, according to network state, carry out corresponding video flowing and export.
Described net cast image processing method, wherein, described steps A also comprises:
After A1, live video are opened, preserve the video flowing cushioned.
Described net cast image processing method, wherein, described step C comprises:
C1, when network state not good, then obtain the video flowing preserved in terminal, export;
C2, when network state good, then carry out live signal output.
Described net cast image processing method, wherein, described Preset Time is 5 seconds.
A kind of net cast image processing system, wherein, comprising:
Live opening module, for receiving the request of user, opens live video;
Network state acquisition module, for obtaining the network state of user terminal every Preset Time;
Video Output Modules, for according to network state, carries out corresponding video flowing and exports.
Described net cast image processing system, wherein, described live opening module comprises:
Cache module, after opening, preserves the video flowing cushioned for live video.
Described net cast image processing system, wherein, described Video Output Modules comprises:
Buffer memory output module, for when network state is not good, obtains the video flowing preserved in terminal and exports;
Live signal output module, good for working as network state, carry out live signal output.
Described net cast image processing system, wherein, described Preset Time is 5 seconds.
Beneficial effect: head of the present invention is by receiving the request of user, open net cast, the network state of terminal is obtained every Preset Time, and outputting video streams, the output of live signal stream is carried out when network state is good time, and preserve buffer memory, when network state is bad, obtain buffer memory, buffer memory is exported, and repeat playing, until when network state is good, then switch to live signal, ensure that user is when pending buffer, can not feel uninteresting, and the carrying out of buffer memory before can be watched, decrease the use of flow.

Embodiment
The invention provides, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, be the flow chart of steps of a kind of net cast image processing method of the present invention, wherein, comprise step:
The request of S1, reception user, opens live video;
S2, obtain the network state of user terminal every Preset Time;
S3, according to network state, carry out corresponding video flowing and export.
Described image processing method of the present invention, first the request of user is received, open live video, open the detection of network state when opening simultaneously, and according to network state, carry out corresponding video flowing to export, network state is good, then show that live signal can export, and network state not good time, often the time of pending buffer is for a long time, therefore take network state detection to realize different video stream export, avoiding period of reservation of number after causing user uninteresting for a long time, affecting the viewing effect of user.
Further, described net cast image processing method, wherein, described step S1 also comprises:
After S101, live video are opened, preserve the video flowing cushioned.In described method of the present invention, step S101, receives the request of user, opens live, when live, the video flowing cushioned can be preserved.So that next time continues viewing.
Further, as shown in Figure 2, be the flow chart of the step S3 of described net cast image processing method, wherein, described step S3 comprises:
S301, when network state not good, then obtain the video flowing preserved in terminal, export;
S302, when network state good, then carry out live signal output.Described method of the present invention, in step S3, Sampling network state, corresponding outputting video streams, in step S101, many videos have been cached with in historical data base, when network state is not good, historical data base can be called, everywhere buffered video, play, avoid period of reservation of number excessively of a specified duration, produce unhappy uninteresting mood, periodically check network state, when network state is recovered, continue unlatching live, row buffering of going forward side by side, ensures that user watches the fluency of video, can not be not good because of network, cause user to watch the video stand-by period excessively of a specified duration.
Further, described net cast image processing method, wherein, described Preset Time is 5 seconds.The preferred Preset Time of preferred embodiment of the present invention is 5 seconds, carries out the detection of network state every 5 seconds.
