Embodiment
First a kind of video broadcasting method embodiment of the present invention being provided describes, and the method can comprise the following steps:
Online broadcasting in target video process, judges the loading speed of video file of current broadcasting and the relation that the loading speed of this video file code stream requires;
If the loading speed of the video file of current broadcasting reaches default very first time threshold value lower than minimum loading speed requirement and the duration of this video file code stream, detect described target video and whether exist and meet the first video file that switches demand, describedly meet the first video file that switches demand and be: and code stream identical with the video file content of current broadcasting is lower than the video file of the code stream of the video file of current broadcasting;
According to testing result, switch to corresponding broadcast mode and play this target video.
Internet era, video resource is more and more, after busy work and life, watches video, has become a kind of mode of the pastime of lying fallow.In the comparatively stable fixed location of network environment, be relatively applicable to watching online video, but not necessarily always stopping at certain place, user watches video, because along with the fast development of mobile terminal, for user provides the mode of watching more easily video.When user when riding public transportation means, wait for bus or etc. people need to kill time time, while having important race, may have the demand of watching video.
User is when watching video, what more focus on is the smooth degree of video playback, so play online in target video process, if network environment changes, especially during network environment variation, be not enough to meet the desired minimum loading speed of code stream of the video file of current broadcasting, and the duration reached default threshold value, will consider to switch to the demand that corresponding broadcast mode can meet smooth playing target video.If at this net environment, also with the code stream of the video file of current broadcasting, play always, easily there is video Caton phenomenon, affect user and experience.
The technical scheme that the embodiment of the present invention provides, in online displaying video process, judges whether to switch to other broadcast modes according to current network environment, if needed, according to switchover policy, is switched to corresponding video file and plays.The smooth degree that has guaranteed largely video playback, has promoted user's experience.
In order to make those skilled in the art understand better the technical scheme in the present invention, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Shown in Fig. 1, be a kind of implementing procedure figure of video broadcasting method of the present invention, it can comprise following basic step:
S110, plays in target video process online, judges the loading speed of video file of current broadcasting and the relation that the loading speed of this video file code stream requires;
So-called video, makes a general reference the various technology that a series of static images are caught, record, process, store, transmit or reappear in signal of telecommunication mode.The development of Internet technology impels all kinds of videos be present on network and can received and play by computer or mobile terminal.
So-called code stream, refers to the data traffic that video file is used within the unit interval, also referred to as code check, is the most important part of in Video coding, image quality being controlled.Under same resolution, the code stream of video file is higher, and compression ratio is less, and image quality is just better.Visible, the video file of high code stream definition when playing is high, also high to the requirement of network environment.
Can there is the video file of a plurality of different code streams in same target video, namely, low code stream, high code stream have thinks corresponding video file, and the loading speed of different video file code stream exists a speed range.Online broadcasting in target video process, variation along with current network environment, the loading speed of the video file of current broadcasting changes thereupon, when the loading speed of the video file of current broadcasting reaches the minimum speed limit that the loading speed of this video file code stream requires, can use this code stream video file to play; In the time can not reaching the minimum speed limit that the loading speed of this video file code stream requires, if use this code stream video file to play, there will be video Caton phenomenon.
So, play online in target video process, judge that the loading speed of video file of current broadcasting and the Relationship Comparison that the loading speed of this video file code stream requires are important, can further determine whether to carry out by judged result the switching of other broadcast modes.
S120, if the loading speed of the video file of current broadcasting reaches default very first time threshold value lower than minimum loading speed requirement and the duration of this video file code stream, detect described target video and whether have the video file that meets the first switching demand;
Describedly meet the first video file that switches demand and be: and code stream identical with the video file content of current broadcasting is lower than the video file of the code stream of the video file of current broadcasting.
A kind of judged result of step S110, the loading speed that is the video file of current broadcasting requires lower than the minimum loading speed of this video file code stream and the duration reaches default very first time threshold value, according to this judged result, can further detect described target video and whether have the video file that meets the first switching demand.
If network environment changes, the loading speed of the video file of current broadcasting also can change thereupon, if the loading speed of the video file of current broadcasting is lower than the minimum loading speed requirement of this video file code stream, show that current network environment has not reached the requirement of minimum loading speed of the video file code stream of current broadcasting, duration reaches default very first time threshold value, such as default very first time threshold value is 5 seconds, will detection trigger target video whether exist and meet the first step of switching the video file of demand.
Default very first time threshold value can arrange as the case may be, and the present invention is not construed as limiting this, and those skilled in the art can, according to the common practise of this area and common technology means, set in advance very first time threshold value.If what arrange is bigger than normal, video card is longer immediately, and user experiences not good; If what arrange is less than normal, network environment may be moment variation then take a turn for the better again, can cause too early performance objective video whether to have the detecting step of the video file of satisfied the first switching demand, thereby according to testing result, may be switched to the video file of the code stream lower than the code stream of the video file of current broadcasting, can not make full use of existing real network resource.
S130, according to testing result, switches to corresponding broadcast mode and plays this target video;
According to the testing result of step S120, switch to corresponding broadcast mode and play this target video.
Switch step is carried out on backstage, if the default very first time threshold value setting in step S200 is reasonable, from the user point of view, the target video of watching is being play always.
The technical scheme that the embodiment of the present invention provides, in online displaying video process, judges whether to switch to other broadcast modes according to current network environment, if needed, is switched to corresponding video file plays according to switchover policy.The smooth degree that has guaranteed largely video playback, has promoted user's experience.
Shown in Figure 2, be the implementing procedure figure that in step S120, the first switching demand video file detects, step S130a and step S131 are respectively the two kinds of situations whether described target video exists the testing result of the video file that meets the first switching demand that detect.
In a kind of embodiment of the present invention, if for there is the video file that meets the first switching demand in the testing result of step S120, exist the identical and code stream of video file content with current broadcasting lower than the video file of the code stream of the video file of current broadcasting, can perform step S130a.
S130a, switches to the described video file that meets the first switching demand and plays;
As previously mentioned, can there is the video file of a plurality of different code streams in same target video, when network environment poor, the loading speed of the video file of current broadcasting reaches default very first time during threshold value lower than the minimum loading speed of this video file code stream and duration, target video detected and have the video file that meets the first switching demand, exist the identical and code stream of video file content with current broadcasting lower than the video file of the code stream of the video file of current broadcasting, switch to the video file that meets the first switching demand and play.
Be understandable that, the height of code stream is relative concept, if there is the video file of two code streams lower than the code stream of the video file of current broadcasting in target video, can be according to order from high to low, the video file that is switched to code stream higher in these two code streams is play, namely, in the situation that network environment allows, play as far as possible the video file of high code stream, for user brings better viewing effect.
In another kind of embodiment of the present invention, if for there is not the video file that meets the first switching demand in the testing result of step S120, do not exist the identical and code stream of video file content with current broadcasting lower than the video file of the code stream of the video file of current broadcasting, can perform step S131 and step S132.
S131, detects the local off-line files corresponding with target video that whether have;
S132, if there is corresponding off-line files, switches to offline mode, with offline mode, plays this target video file.
As previously mentioned, can there is the video file of a plurality of different code streams in same target video, online broadcasting in target video process, when network environment poor, the loading speed of the video file of current broadcasting is lower than the minimum loading speed of this video file code stream, and the duration reaches default very first time during threshold value, the video file that target video does not exist the code stream lower than the code stream of the video file of current broadcasting detected, namely the video file of not low than the code stream of the video file of current broadcasting code stream can switch, can further detect the local off-line files corresponding with target video that whether have, if there is corresponding off-line files, switch to offline mode, with offline mode, play this target video.
Shown in Figure 3, in a kind of specific embodiment of the present invention, at step S110, play online in target video process, after judging the loading speed of video file of current broadcasting and the relation of the loading speed of this video file code stream requirement, can also comprise following two steps:
S140, if the loading speed of the video file of current broadcasting requires higher than the high loading rate of this video file code stream and the duration reaches the second default time threshold, detect described target video and whether exist and meet the second video file that switches demand;
Describedly meet the second video file that switches demand and be: and code stream identical with the video file content of current broadcasting is higher than the video file of the code stream of the video file of current broadcasting.
S150, if existed, switches to the described video file that meets the second switching demand and plays.
Internet era, network quality promotes gradually, the 4G epoch arrive, under 4G network, can quick data transfering, high-quality audio plays, video file etc.When user is in mobile status, when network environment is taken a turn for the better by difference, once the loading speed of the video file of current broadcasting is higher than the high loading rate requirement of this video file code stream, and the duration reaches the second default time threshold, the second default time threshold can be 10 seconds, detect described target video and whether have the video file that meets the second switching demand, if existed, switching to the described video file that meets the second switching demand plays, namely be switched to more identical than the video file content of current broadcasting, and code stream is higher than the video file of the code stream of the video file of current broadcasting.
Be understandable that, the second default time threshold can be identical with very first time threshold value, also can be different, and the present invention is not construed as limiting this, and those skilled in the art can, according to practical application request, set in advance the second time threshold.
Meet user to the Demand Base of fluency on, definition is also important for user, when so network environment being detected and can meet the video file of high code stream more, automatically switch to high code stream video file and play, the experience that can provide more smooth, watch more clearly video for user.
Shown in Figure 4, in a kind of specific embodiment of the present invention, can also comprise the following steps:
S210, receives after video playback instruction, reads target video information;
In actual applications, for network traffics limited users, more careful for the use of network traffics, also relatively mind whether be with online mode playing video file, so before playing target video online, can first carry out this step.
User sends play instruction to interested target video, and user clicks the link of corresponding video file, receives after this instruction, first reads target video relevant information, as video name, video id etc.
S220, checks the local corresponding off-line files that whether has;
According to the target video information reading, in this locality, as computer or mobile terminal, check and whether have corresponding off-line files.
Off-line files can be that user downloads in advance and be saved in local video file in the better situation of network environment, can also be that user synchronously downloads and be saved in local video file while watching target video online.
If local, preserve the off-line files corresponding with target video, perform step S230, if there is no corresponding off-line files, perform step S240.
S230, reads the broadcast address of off-line files, with offline mode, plays this target video;
If local, preserve the off-line files corresponding with target video, can read the broadcast address of this off-line files, with offline mode, play this target video.Can save more network traffics for user like this.
S240, plays with online mode;
If local, do not have to preserve the off-line files corresponding with target video, in the situation that network environment can be used, can play this target video with online mode, and then execution step S110.
Before playing target video, first in this locality, check whether there be the off-line files corresponding with target video, if had, preferentially select off-line files to play, for user has saved data traffic.
Certainly, at off-line or play online in target video process, if receive broadcast mode switching command, according to this instruction, switch to corresponding broadcast mode and play described target video.
Common audio/video player system can provide option to play target video by which kind of broadcast mode of user's active choice for use.General option is smoothness, high definition, super clear, local.Smoothness, high definition, super sorting be the video file of the different code streams of corresponding file destination not, the local corresponding local off-line files corresponding with target video of preserving.
For better understanding, with instantiation, describe:
First example, off-line is play in target video process, user thinks that the code stream of the local off-line files of preserving is not enough to meet the demand of oneself, and the network environment in own region of living in is better, user can initiatively select the video file of code stream corresponding to high definition, according to user-selected video file, plays online;
Second example, plays in target video process online, and user thinks that the code stream of current in progress video file can not meet the demand of oneself, can initiatively select a kind of video file of high code stream, according to user-selected video file, plays.
Different user is different for the quality requirement of video playback, provides option initiatively to select for user, and then is switched to user-selected video file continuation broadcasting, more meets user's actual use habit.
