Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
embodiment of the method:
With reference to Fig. 1, show the flow process of video broadcasting method first embodiment of the present invention, this method for optimizing embodiment comprises the following steps:
Step S101: receiver, video playing request;
In the preferred embodiment, video playback request includes the address designation of data to be played;
Step S102: obtained and broadcast controlled condition, broadcasts controlled condition according to address designation and this of data to be played and downloads data to be played;
In the preferred embodiment, this broadcasts controlled condition for identifying data volume size and the controlled condition broadcast in process for the working the data to be played broadcast that need to download.
This is broadcast controlled condition and can preset as required, also can dynamically arrange according to network environment; Setting principle is: not only will ensure that video can rise fast and broadcast, picture can also be avoided to occur once the situation showing buffering, to ensure after normal play that buffer time is more reasonable, thus effectively can avoid the problem that causes period of reservation of number long when network condition is poor.
For improve playing efficiency, reduction user stand-by period (comprised between sowing time with playing process in stand-by period), for data downloading process, the present invention preferably adopts asynchronous downloading mode.
In the further preferred embodiment of this method embodiment, rise and broadcast controlled condition and included and broadcast time threshold; The above-mentioned address designation according to data to be played broadcasts with rising the method that controlled condition downloads described data to be played, specifically comprises: be used for the data volume of the data to be played broadcast according to playing threshold calculations between sowing time; Then, download for working the data to be played broadcast according to the data volume for working the data to be played broadcast and address designation.
Wherein, the above-mentioned data volume for working the data to be played broadcast can adopt following methods to calculate:
For working the data volume of the data to be played broadcast=rise and broadcast the code check of time threshold × video to be played.
Step S103: broadcast the described data to be played of controlled condition broadcasting according to rising; And, calculate the playing duration of described data to be played;
Step S104: judge whether the playing duration of data to be played is greater than default playing duration; If so, S105 is gone to step; Otherwise go to step S103 to continue to play data to be played;
Default playing duration in the present embodiment refer to system from broadcast the Rule of judgment that state enters normal playing status.Generally, when adopted broadcast time threshold (Prepare_Buffer_Duration) as rise broadcast controlled condition time, default playing duration can be artificial experience settings, also can be set to the difference of Prepare_Buffer_Duration and minimum reproduction time threshold value (Min-Buffer-Duration), also can directly be set to broadcast time threshold (Prepare_Buffer_Duration).
Step S105: obtain Play Control condition, according to data to be played remaining in Play Control condition downloading and playing buffering area.
In the preferred embodiment, this Play Control condition can preset as required, also can dynamically arrange according to network environment; When Play Control condition adopts the mode preset, the Play Control condition in step S105 can be broadcast controlled condition and obtains simultaneously with rising in step S102, also can rise broadcast after obtain again; When Play Control condition adopt dynamically arrange mode time, the Play Control condition in step S105 preferably rise broadcast after obtain again.
This preferred embodiment broadcasts controlled condition by arranging Play Control condition respectively and rising, can when ensure rise as early as possible broadcast, effectively avoid picture once show buffering situation occur, thus preferably resolve existing player when preset buffering area larger or network speed is slow period of reservation of number may be caused long bad experience problem.
With reference to Fig. 2, show the flow process of video broadcasting method second embodiment of the present invention, in the preferred embodiment, adopted and broadcast time threshold (Prepare_Buffer_Duration) and minimum and broadcast time threshold and broadcast controlled condition and control video as rising and work the process of broadcasting; Adopt minimum reproduction time threshold value (Min-Buffer-Duration) and the highest reproduction time threshold value (Max-Buffer-Duration) to control the video display process after broadcasting as Play Control condition, specifically comprise:
Step S201: receive and comprise the video playback request of played data address designation of needing;
In the preferred embodiment, download and playing process for ease of asynchronous process, the system (or device) performing described method is provided with upper strata player and lower floor's player, lower floor's player has two types, comprise the StagefrightPlayer of responsible live NuPlayer and responsible program request, they all adopt identical buffer technology.Upper strata player can judge its type according to the adress analysis of data to be played, for live type, NuPlayer can be selected as lower floor's player and instantiation; For program request type, then StagefrightPlayer can be selected as lower floor's player and instantiation.Other modules can not change.
Step S202: obtained and broadcast controlled condition;
In this method embodiment, to rise and broadcast time threshold (Prepare_Buffer_Duration) and minimum and broadcast time threshold (Low_WaterMark_Duration) and broadcast controlled condition as rising, rise broadcast controlled condition sphere of action only before rising and broadcasting, understand after broadcasting and carry out Play Control according to Play Control condition.
For Android system platform, upper strata player can adopt to issue orders obtained play Broadcast Control condition setting to lower floor's player:
setParameter（9500，Prepare_Buffer_Duration）；
setParameter（9501，Low_WaterMark_Duration）；
In mentioned order, 9500 and 9501 is the communication cryptology that upper strata broadcast unit and lower floor's broadcast unit are arranged.
The effect of Prepare_Buffer_Duration is that notice lower floor player needs buffering can play data how long, and the data volume that lower floor's player can go out cushion according to this Time Calculation has much.In order to image can show as early as possible and rise broadcast after can not there is buffering situation at once, need setting one can not too small can not be excessive Prepare_Buffer_Duration value; Occur buffering situation at once after too small meeting has made to broadcast, user experiences bad; Excessive, need could rise for a long time and broadcast existing picture, user's impression is also bad.
Such as, if definition Prepare_Buffer_Duration=1.5s, lower floor's player can by calculating the data of 1.5s buffering for the code check of broadcasting channel; Suppose that the code check of this channel is 1000KB, then required amount of buffered data (namely for working the data volume of the data to be played broadcast) is 1000KB * 1.5s=1500KB, is under the bandwidth of 2M/s, as long as namely 0.75s can cushion complete in theory at network speed.
Minimum the plaing a part of above-mentioned Low_WaterMark_Duration(broadcasts time threshold) be the low level threshold values that play buffering pond is set, lower than this value, player will suspend broadcasting, make upper strata player be in loading state.Working one of object arranging this value before broadcasting is guarantee that Low_WaterMark_Duration value is less than the value set by Prepare_Buffer_Duration, and be greater than reality can reproduction time (as shown in Figure 4), thus ensure that picture is firm as far as possible and there will not be once showing the situation cushioned while having made ensure sowing time to play fast.The threshold values that general Low_WaterMark_Duration is arranged is lower, may only only have hundreds of millisecond, and Prepare_Buffer_Duration value may be several seconds.Such as, if definition Low_WaterMark_Duration is 200ms, suppose that the code check of this channel is 1000KB, if so the data volume of buffering area lower than the size of (200ms/1000) * 1000KB/s=200KB, then can suspend broadcasting.
Step S203: according to the asynchronous download of the address designation of data to be played data to be played;
For Android system, upper strata player sends warning order prepareAsync (), and lower floor's player receives this order, according to the buffer condition arranged above (rise and broadcast condition), can download data to be played, and be cached in buffering area.Lower floor's player, after having cushioned data and other some data initialization work, can be in by order onPrepared () notice upper strata player the state that can play.
Step S204: whether the data volume to be played judging in buffering area has met is broadcast time threshold; If so, go to step the data to be played that S205 starts in play buffer, go to step S206 simultaneously and perform follow-up Play Control process; Otherwise, go to step the feedback result of S204 waiting step S203.
Step S205: decoding and output buffer in data to be played;
When satisfied broadcasting condition, upper strata player sends play command start (), and now lower floor's player enters broadcast state, starts to be separated sound, video data, decodes and does sound, audio video synchronization, output sound video.
In a further preferred embodiment, reaching for avoiding the data in buffering area or be less than reality can reproduction time and cause playing abnormal problem, rise after broadcasting beginning, also comprise: to judge in buffering area whether remaining data volume to be played is less than minimum and broadcast time threshold Low_WaterMark_Duration; If so, decoding, the output procedure of data to be played is then suspended.
Step S206: obtain minimum reproduction time threshold value and the highest reproduction time threshold value as Play Control condition;
Step S207: according to the data to be played in Play Control condition play buffer.
After broadcasting starts, start second time and arrange buffering area broadcasting condition, after ensureing normal play, buffer time is reasonable.Play Control condition comprises minimum reproduction time threshold value (Min-Buffer-Duration) and the highest reproduction time threshold value (Max-Buffer-Duration).
For Android system platform, upper strata player can adopt to issue orders the Play Control condition setting that obtained to lower floor's player:
setParameter（9501，Min-Buffer-Duration）；
setParameter（9502，Max-Buffer-Duration）；
In mentioned order, 9501 and 9502 is the communication cryptology that upper strata broadcast unit and lower floor's broadcast unit are arranged.
Such as, the time arranged by Prepare_Buffer_Duration is 1s, and so timer again can arrange buffer size after 1s.Minimum reproduction time threshold value Min-Buffer-Duration and the highest reproduction time threshold value Max-Buffer-Duration can be with the use of, minimum reproduction time threshold value Min-Buffer-Duration is greater than reality can reproduction time, and is less than the highest reproduction time threshold value Max-Buffer-Duration.When the time that the anticipated playback time of buffering area remaining data defines lower than Min-Buffer-Duration, suspend and play.When the time that buffering area remaining data can be play higher than Max-Buffer-Duration time, can buffering be suspended, save bandwidth for other application requests network data of equipment.
With reference to Fig. 3, show in above-mentioned second embodiment of the method and close threshold value between sowing time mutually, minimum is broadcast time threshold, minimum reproduction time threshold value, the highest reproduction time threshold value, reality can relation between the conditional parameter such as reproduction time, wherein:
The highest reproduction time threshold value > rise broadcast time threshold >=minimum reproduction time threshold value >=minimum broadcast time threshold >=reality can reproduction time.
Above-mentioned reality can reproduction time refer in theory can time of displaying video, when the data volume in buffering area only meet reality can reproduction time time, if the moment of playing can not obtain new data, playing process will force stop/pause, also may occur that other play abnormal problem;
In addition, the setting of above-mentioned conditional parameter is relevant to network environment, generally, rises and broadcasts time threshold and broadcast reproduction time threshold value slightly larger than minimum; When network speed is very fast (when web download speed is not less than video playout speed), broadcast to rise as early as possible, reduce the stand-by period of user, time threshold can be broadcast be set to rising a relatively little numerical value, generally broadcast with minimum time threshold, minimum reproduction time threshold value, reality can reproduction time value equal; When network speed is slower, in order to reduce suspending count, time threshold can be broadcast be set to rising a relatively large numerical value, and rise broadcast minimum of time threshold > minimum reproduction time threshold value > broadcast time threshold > reality can reproduction time.
It should be noted that, above-mentioned Broadcast Control conditional parameter and Play Control conditional parameter, can be provided according to various network condition and the experience of oneself by those skilled in the art, also can automatically test network environment at that time by program, the type and size of video to be played calculate the size of buffering area, thus make netcast more smooth.
With reference to Fig. 4, the sequential chart of information exchanging process between the parts included by system showing above-mentioned second embodiment of the method, is described as follows:
First, after upper strata player receives media play request, the address designation of data to be played is transmitted to lower floor's broadcast unit by communication service unit;
Secondly, upper strata player arranges a Broadcast Control conditional parameter of lower floor's player by communication service unit;
Rise and broadcast controlled condition and comprised and broadcast time threshold Prepare_Buffer_Duration; The effect of Prepare_Buffer_Duration tells that lower floor's broadcast unit needs buffering can play data how long.The sphere of action of this setting only, before rising and broadcasting, can carry out Play Control according to the buffer size of setting in addition below after broadcasting.
3rd, upper strata player sends asynchronous data download instruction by communication service unit to lower floor's player, and then, lower floor's player sends asynchronous data download request to data download unit;
4th, data download unit is to lower floor player feedback download status information, and lower floor's player judges whether can start to play according to buffer parameters, if passable, then by communication service unit to upper strata player feedback status information;
5th, upper strata player sends video playback instruction by communication service unit to lower floor's player;
6th, rise after broadcasting, upper strata player arranges the Play Control condition of lower floor's player by communication service unit.
Wherein, above-mentioned Play Control conditional parameter comprises minimum reproduction time threshold value Min-Buffer-Duration and the highest reproduction time threshold value Max-Buffer-Duration; When the video data time in buffering area is less than Min-Buffer-Duration, lower floor's player will suspend video display process, until the data that data download unit downloads in buffering area can meet broadcast request; When the video data time in buffering area is more than or equal to Max-Buffer-Duration, data download unit will suspend data downloading process, to save the network bandwidth other application requests network data for equipment.
