Word comment data is updated, so as to display in real time newest comment content.
Fig. 2 shows the sides for showing text information with barrage in net cast that one specific embodiment of the present invention provides
The flow chart of method.Since traditional technology binds the image frame of word content and video, it is applicable only to
In the video files such as repeatable cartoon, the film broadcasted, it can not be applied in live video, so in the present embodiment, being
Advantage of the invention is highlighted, is illustrated for showing barrage content in live video, but those skilled in the art's energy
Enough understand, method shown in Fig. 2 also can be applied in other non-live videos.As shown in Fig. 2, this method includes such as
Lower step:
Step S210: text reviews data relevant to live video stream are obtained in real time.
In this step, text reviews data can be from website associated with live video, note or forum etc..
For example, many football fans, can be too impatient in relevant opinion before kickoff when live video is world cup ball match
The mood of oneself excitement is expressed on altar, note, and the soccer star liked of oneself is wished to win the game.Therefore, live video just
Before formula starts, by being screened to the comment data in associated website, note or forum, so that it may obtain a set of complete
Whole text reviews data are as barrage data.So-called barrage data are content shown by barrage, are wrapped in barrage data
Containing a line or multline text information being made of text reviews data.It specifically, can be according to a variety of when screening comment data
Rule is screened, for example, can be screened according to the comment time of this comment data and/or pageview, when by commenting on
Between compared with the new and/or higher comment data of pageview be determined as barrage data；Also, it can also be by preset keyword to packet
Comment data containing indecency content is filtered out.
Step S220: according to above-mentioned text reviews data and preset barrage modelling barrage video flowing.
Wherein, barrage model is used to set the display mode of barrage data.For example, can be set in barrage model following
It is one or more in content: the threshold range of the line number of text information shown by each frame of barrage video flowing, every a line
The threshold range of spacing between the threshold range of the rolling speed of text information, each row text information and text information
Font/font size/color.
According to barrage model by the barrage data creating in step S210 be several barrage video frames, these barrages regard
In frequency frame, the rest part in addition to barrage data is pellucidity, specifically when setting, the background of each frame can be respectively provided with
For colorless and transparent state.Barrage video flowing is formed when these barrage video frames continuously play.
Step S230: live video stream is played by the first play control, and barrage view is played by the second play control
Frequency flows, wherein barrage video flowing is covered on live video stream.
In this step, live video stream and barrage video flowing, also, barrage are played simultaneously by two play control
Video flowing is covered on live video stream.Since the background of each frame in barrage video flowing is colorless and transparent state,
When barrage video stream layers, which are stacked in, to be broadcasted on live video stream, it is equivalent to user's bring visual effect in viewing one
Live video stream with barrage data content, to be used under the premise of not influencing the broadcasting content of former live video stream
Family can experience entertainment and interactivity brought by barrage.
When specific implementation, the first play control and the second play control can flexibly select various Graphics Controls to realize,
For example, TextView, Button and CheckBox etc..It is highly preferred that the first play control and the second play control can pass through
SurfaceView control is realized.SurfaceView control is the control that Android system provides, in the dynamic effect ratio of processing
There is significant advantage when more video content: due to SurfaceView control possess independent drawing surface (i.e. not with its
Host window shares the same drawing surface), therefore the UI (User Interface, user interface) of SurfaceView can be with
It is drawn in an independent thread；Thus main thread resource would not be occupied, inputs not so not will lead to user
To timely responding to (on the drawing surface that the UI of itself is plotted in host window by common Android control, thus be to apply
It is drawn in the main thread of program, and main thread is other than drawing UI, it is also necessary to user's input is responded in time, therefore
The problem of be easy to causeing user's input that cannot timely respond to).It can be seen that can be by using SurfaceView control
Picture is drawn in one individual threads in addition created, and can be improved the speed of video rendering, makes the result of broadcast of video more
Add smoothness.
It can be seen that in this step, live video stream can be played by the first SurfaceView control, led to simultaneously
It crosses the 2nd SurfaceView control and plays barrage video flowing, and when carrying out the setting of figure layer relationship, by the figure of barrage video flowing
Layer is arranged on the figure layer of live video stream, and barrage video flowing is made to be covered on the surface of live video stream.
It, can also be to the play time of barrage video flowing when playing live video stream and barrage video flowing in step S230
Carry out a variety of settings.For example, barrage video flowing can broadcast simultaneously with live video stream, it may be assumed that when beginning is broadcast live, start simultaneously at
Play the barrage content pre-set；It is opened after preset time (such as ten minutes) are broadcasted in live streaming alternatively, may be set to be
Begin to play the barrage content pre-set.Moreover, in order to meet the diversified demand of user, second broadcasts during live streaming
Put control can also according to the pause play instruction received or replay instruction to barrage video flowing being played on execute
Corresponding operation.
It can be seen that the barrage video flowing in the present embodiment is independently of live video stream, it is not necessary in live video stream
Image frame is bound, and so as to update barrage data in real time, user is made to see newest comment content in time；In addition,
Since before live video starts barrage data can be obtained previously according to relevant forum or note, to produce
Whole barrage video flowing, therefore, the barrage video flowing in the present embodiment can start simultaneously at broadcast with live video stream, make user
It is seen that barrage data while watching live video.
Fig. 3 shows the process for the method that barrage is shown in net cast that another specific embodiment of the present invention provides
Figure.In this embodiment, it is still illustrated for showing barrage content in live video, but those skilled in the art's energy
Enough understand, method shown in Fig. 3 also can be applied in other non-live videos.The embodiment and reality shown in Fig. 2
The main distinction for applying example is: during playing barrage video flowing, can according to user terminal increase newly text reviews number
According to real time modifying barrage data and barrage video flowing, enable the newest user comment data of barrage video flowing real-time display.
As shown in figure 3, this method comprises the following steps:
Step S310: barrage data are determined according to the comment data that user terminal is delivered.
Similar with step S210, in this step, the comment data that user terminal is delivered can derive from and live video
Associated website, note or forum etc..For example, when live video be world cup ball match when, many football fans kickoff it
Before, the mood of oneself excitement too impatient can be all expressed on relevant forum, note, and wish the soccer star liked of oneself
It wins the game.Therefore, before live video formally starts, by the comment number in associated website, note or forum
According to being screened, so that it may obtain the barrage data of complete set.It specifically, can be according to a variety of when screening comment data
Rule is screened, for example, can be screened according to the comment time of this comment data and/or pageview, when by commenting on
Between compared with the new and/or higher comment data of pageview be determined as barrage data；Also, it can also be by preset keyword to packet
Comment data containing indecency content is filtered out.
Step S320: according to preset barrage model by barrage data creating be barrage video flowing.
According to barrage model by the barrage data creating in step S310 be several barrage video frames, these barrages regard
In frequency frame, the rest part in addition to barrage data is pellucidity, specifically when setting, the background of each frame can be respectively provided with
For colorless and transparent state.Barrage video flowing is formed when these barrage video frames continuously play.Wherein, barrage model is for setting
Determine the display mode of barrage data.For example, at least one in the following contents: barrage video flowing can be set in barrage model
Each frame shown by the threshold range of line number of text information, each row text information rolling speed threshold range,
The threshold range of spacing between each row text information and font/font size/color of text information.
For example, in this example, it is assumed that barrage data obtained in step S310 include 1000 comment datas, then exist
In step S320, the display mode of this 1000 comment datas is set according to barrage model.Assuming that being provided in barrage model
The threshold range of the line number of text information shown by each frame picture of barrage video flowing is 1 to 5, it may be assumed that each frame picture
On at least show a line text information, to ensure that user can watch barrage data at any time；And it is at most aobvious on each frame picture
Show five-element's text information, to prevent from influencing user because of the entire screen of barrage data cover normally watching live video.In barrage
The threshold range that the rolling speed of each row text information is alsied specify in model is 0-6mm/s, it may be assumed that text information rolls most
Low velocity is 0mm/s, and when rolling speed is 0mm/s, text information will stop a moment on the screen；Text information rolls most
It is at high speed 6mm/s, to ensure that human eye can pick out the particular content of text information.Therefore, it is provided according in barrage model
The threshold range of text information line number, each row text information rolling speed threshold range and each row text information
Between the threshold range of spacing etc. set the display modes of this 1000 comment datas: for commenting on the longer text of content
Comment data sets more line number for it, and is arranged slightly fast by its rolling speed；And the text shorter for comment content
Comment data sets less line number for it, and is arranged slightly slow by its rolling speed, to guarantee what the two was streaked on the screen
Time is essentially identical.
Step S330: live video stream is played by the first play control, and barrage view is played by the second play control
Frequency flows, wherein barrage video flowing is covered on live video stream.
In this step, live video stream and barrage video flowing, also, barrage are played simultaneously by two play control
Video flowing is covered on live video stream.Since the background of each frame in barrage video flowing is colorless and transparent state,
When barrage video stream layers, which are stacked in, to be broadcasted on live video stream, it is equivalent to user's bring visual effect in viewing one
Live video stream with barrage data content, to be used under the premise of not influencing the broadcasting content of former live video stream
Family can experience entertainment and interactivity brought by barrage.
When specific implementation, the first play control and the second play control can flexibly select various Graphics Controls to realize,
For example, TextView, Button and CheckBox etc..It is highly preferred that the first play control and the second play control can pass through
SurfaceView control is realized.SurfaceView control is the control that Android system provides, in the dynamic effect ratio of processing
There is significant advantage when more video content: due to SurfaceView control possess independent drawing surface (i.e. not with its
Host window shares the same drawing surface), therefore the UI (User Interface, user interface) of SurfaceView can be with
It is drawn in an independent thread；Thus main thread resource would not be occupied, inputs not so not will lead to user
To timely responding to (on the drawing surface that the UI of itself is plotted in host window by common Android control, thus be to apply
It is drawn in the main thread of program, and main thread is other than drawing UI, it is also necessary to user's input is responded in time, therefore
The problem of be easy to causeing user's input that cannot timely respond to).It can be seen that can be by using SurfaceView control
Picture is drawn in one individual threads in addition created, and can be improved the speed of video rendering, makes the result of broadcast of video more
Add smoothness.
It can be seen that in this step, live video stream can be played by the first SurfaceView control, led to simultaneously
It crosses the 2nd SurfaceView control and plays barrage video flowing, and when carrying out the setting of figure layer relationship, by the figure of barrage video flowing
Layer is arranged on the figure layer of live video stream, and barrage video flowing is made to be covered on the surface of live video stream.
It, can also be to the play time of barrage video flowing when playing live video stream and barrage video flowing in step S330
Carry out a variety of settings.For example, barrage video flowing can broadcast simultaneously with live video stream, it may be assumed that when beginning is broadcast live, start simultaneously at
Play the barrage content pre-set；It is opened after preset time (such as ten minutes) are broadcasted in live streaming alternatively, may be set to be
Begin to play the barrage content pre-set.Moreover, in order to meet the diversified demand of user, second broadcasts during live streaming
Put control can also according to the pause play instruction received or replay instruction to barrage video flowing being played on execute
Corresponding operation.In addition, both can be mutually indepedent between the operation of the first play control and the operation of the second play control, it can also
With there are fixed relationships.Operating and, there are when fixed relationship, being somebody's turn to do between the operation of the second play control when the first play control
Fixed relationship comprises at least one of the following: when the first play control temporarily plays, sending pause to the second play control and plays
It instructs so that second play control pause plays；When the first play control replays, sent to the second play control
Instruction is replayed so that second play control replays.That is, when live video stream temporarily plays, barrage
Video flowing also suspends therewith, and when live video stream continues to play, barrage video flowing also continues to play therewith.Also, second broadcasts
The implementation of control pause broadcasting is put either content being played on is made to be still in display area；It is also possible to make
The content of broadcasting disappears from display area.Specifically, when user can suspend broadcasting to the second play control according to actual needs
Implementation be configured: if user compare concern barrage data content, can set temporary for the second play control
Stopping time makes barrage content being played on be still in display area, so that user goes through；If user less pays close attention to barrage
Data content can then set the second play control to making barrage content being played on disappear from display area when pause,
That is the display area content that only shows live video stream, consequently facilitating user checks the close-up in live video stream.
Step S340: barrage data obtained in the comment data real time modifying step S310 increased newly according to user terminal,
Barrage video flowing obtained in step S320 is updated according to above-mentioned preset barrage model and modified barrage data, and is led to
It crosses the second play control and plays updated barrage video flowing.
That is, during playing barrage video flowing by the second play control, it can also be further to broadcasting
In barrage video flowing carry out real-time update.Renewal frequency can be determined flexibly according to the actual situation, for example, can be in conjunction with comment
The renewal frequency of data is set: when newly-increased comment data is more more frequent, renewal frequency can be arranged higher, with
Just newest comment content is increased in barrage in time.
Wherein, in real time modifying barrage data, newly-increased comment data can be inserted into original barrage data, or
Partial content in original barrage data can also be replaced with newly-increased comment data by person.When using first way,
After getting newly-increased comment data, just the newly-increased comment data got is inserted into generated barrage data,
When specific insertion, the middle section of barrage data can be inserted, the tail portion of barrage data also can be inserted, it can be seen that,
When using which, with the broadcast of live video, barrage content also will be more and more, more and more abundant, and which is suitable for
