When application VOD technologies carry out video on demand, there is technical issues that network speed environment is poor and causes video can not.
Based on above-mentioned hardware configuration, the embodiment of video broadcasting method of the present invention is proposed.
With reference to Fig. 2, Fig. 2 is the flow diagram of video broadcasting method first embodiment of the present invention.
In the first embodiment, the video broadcasting method includes the following steps：
Step S10：When by VOD technology program request current videos, the buffered data of the current video is obtained, and judge
Whether the data volume of the buffered data is less than or equal to predetermined threshold value；
It is understood that executive agent is smart television.When user is when using smart television displaying video programs, by
The broadcasting of video is carried out in smart television application VOD technologies, when network speed is poor, broadcasting will be suspended to carry out the buffering of video.
But if network environment is not only unstable but also network speed is extremely low, the broadcasting of video is finally carried out by video buffer, video can be caused
Interim card state is constantly in, is soon carried out in the state of " pause video playing go forward side by side row buffering " with " play buffering video "
Switching causes the experience that user watches video poor.It, can be when network speed be poor, to video to be played in view of above-mentioned reason
Record screen is carried out, and plays the picture of record screen to realize the broadcasting of video.Because VOD technologies are the mode watched online, VOD skills
Art can not provide the function being locally-downloaded, also, VOD technologies can not also provide the memory space of larger capacity, so, pass through record
The mode of screen carrys out the final broadcasting for realizing video, can well combine into VOD technologies.
In the concrete realization, for example, when smart television is in the video that A programs are played by VOD technologies, if ensureing A sections
Mesh can be using the minimum network speed of smooth playing as 500KB/S, and when real-time network speed when playing A programs is 400KB/S, due to real-time
Network speed is less than the minimum network speed, then can judge whether the data volume of the buffered data of A programs is less than or equal to predetermined threshold value again.Its
In, if the data volume of the buffered data of A programs is the video of 2 seconds, and the video that predetermined threshold value is 10 seconds, due to buffered data
Data volume is less than or equal to predetermined threshold value, can assert that A programs can not smooth playing.
Step S20：The buffered data data volume be less than or equal to the predetermined threshold value when, to the current video into
Row record screen obtains record screen file, and the record screen file is played out.
It should be understood that when A programs can not smooth playing when, record screen can be carried out to A programs, by recording screen to generate A
The local video of program, user can watch program by directly opening the local video.Since VOD technologies can not provide local
The function of download, so, record screen operation can be carried out to the smart television for applying VOD technologies, video can be well realized
Normal play avoids video from frequently buffering and occurs with the situation of interim card.
In the present embodiment by video can not smooth playing when, record screen is carried out to current video, it is achieved thereby that in VOD
Technology can not ensure to watch video glibly by playing local record screen video during the smooth playing of video, also just overcome
When application VOD technologies carry out video on demand, there is technical issues that network speed environment is poor and causes video can not.
With reference to Fig. 3, Fig. 3 is the flow diagram of video broadcasting method second embodiment of the present invention, based on shown in above-mentioned Fig. 2
First embodiment, propose the second embodiment of video broadcasting method of the present invention.
In a second embodiment, the step S20, specifically includes：
Step S201：When the data volume of the buffered data is less than or equal to the predetermined threshold value, work as forward sight described in acquisition
The frame per second of frequency；
It is understood that when carrying out record screen to current video, that is, A programs, it is contemplated that A programs exist simultaneously video letter
Breath and audio-frequency information, also, it is different from sound to there are video pictures when playing for the record screen file finally got in order to prevent
The situation of step can obtain record screen file, so as to ensure that video is drawn when screen file is recorded in generation by the way of timestamp is directed at
Face is synchronous with sound.
In the concrete realization, when the data volume of the buffered data of A programs is the video of 2 seconds, less than predetermined threshold value i.e. 10
The video of second will first obtain the play frame rate of A programs.
Step S202：The current video is captured according to the frame per second, to grab image frame to be presented；
It is understood that in the play frame rate for getting A programs, A programs are captured based on the play frame rate.Its
In, frame per second is for recording display frame number per second, the intrinsic frame per second of the video by obtaining A programs, and based on the intrinsic frame per second come
Capture A programs, it is ensured that is got records the clear of video data when shielding file with without record screen A program normal plays
Spend it is identical, if not capturing A programs according to the intrinsic frame per second, and use frame per second more smaller than the intrinsic frame per second just capture record shield it is literary
Part, it is relatively low that the record screen file finally grabbed can play not smooth or clarity.
Step S203：The image frame to be presented is preserved, and records the timestamp of the image frame to be presented；
Step S204：Audio data corresponding with the image frame to be presented is obtained based on the timestamp, is treated described
Displaying image frame is merged with the audio data, records screen file to obtain, and the record screen file is played out.
It should be understood that after the frame per second based on A programs gets the image frame to be presented of A programs, can record current
The timestamp of image frame to be presented got, and audio number corresponding with the image frame to be presented is obtained based on the timestamp
According to ensure that image frame and audio are synchronous, it is first prior to audio or audio will not to there is picture when playing and recording screen file
In the situation of picture.
Further, the step S202, can also include:It instructs, obtains small in response to frame rate adjustment input by user
In each preset frame rate of the frame per second equal to the current video, mesh is chosen from each preset frame rate according to frame rate adjustment instruction
Mark frame per second；The current video is captured according to the target frame rate, obtains image frame to be presented.
It is understood that in view of poor or when network speed is more unstable in network speed, the mode that record is shielded can be taken to make
Program A can finally be watched glibly by obtaining user.But when network speed is excessive compared with slow but program A frame per second, if still according to program A
Larger frame per second capture image frame to be presented, the time for finally getting complete record screen file may be caused longer.So
In view of the difference of network speed, user can freely choose the frame per second of crawl image frame to determine the clarity of record screen file got
With taking, because the frame per second for capturing video is bigger, the clarity of record screen file finally got is also higher, but network speed
It is it is required that more costly and time consuming longer.
It in the concrete realization, can be in the operation interface of smart television when the intrinsic frame per second for getting program A is 100
Multiple optional frame per second of the display from 0 to 100 are for selection by the user.If user by click smart television or with smart television
The physical button of the remote controler matched or virtual key choose target frame rate, for example, multiple optional frames that can be from 0 to 100
It is 50 that target frame rate is chosen in rate, then can capture program A according to target frame rate 50, is captured and saved by intrinsic frame per second 100 than it
Mesh A is lower but time-consuming shorter according to the record screen file clarity that target frame rate 50 grabs if network speed remains unchanged.
Corresponding audio is determined in the present embodiment based on the timestamp of image frame so that final to merge image frame and audio
The record screen file got is not in picture and the nonsynchronous situation of sound when playing.In addition, by being based on current video
Frame per second capture image frame, can ensure the clarity of record screen file well.
With reference to Fig. 4, Fig. 4 is the flow diagram of video broadcasting method 3rd embodiment of the present invention, based on shown in above-mentioned Fig. 3
Second embodiment, propose the 3rd embodiment of video broadcasting method of the present invention.
In the third embodiment, after the step S202, the video broadcasting method further includes：
Step S202'：Check in the image frame to be presented whether display reminding information；
It is understood that in crawl image frame and during preserving image frame, invalid image frame may be grabbed,
Specifically, there may be prompt message in the picture grabbed, " to be captured for example, there are prompt words for the center of picture
In, just a moment,please " prompt messages such as " buffering ", with characterization because network is relatively slow or player reason and occur can not be normal
The problem of capturing image frame.But if during recording and shielding, there will be the picture of above-mentioned prompt word, also typing ultimately generates
In record screen file, because the above-mentioned picture including prompt word is not present in itself in the video pictures of program A, typing record screen file
Also it affects user and normally watches program A, so, file is shielded in the picture not typing record that this can be included to prompt word.
In the concrete realization, it after the image frame to be presented for grabbing program A, first detects the image frame to be presented and whether there is
Prompt message if there is no prompt messages, preserves the image frame to be presented.
When not showing the prompt message in the image frame to be presented, step S203 is performed.
Further, after the step S202', the video broadcasting method further includes：
When showing the prompt message in the image frame to be presented, step S203' is performed.
Step S203'：The image frame to be presented is abandoned, the next frame of the image frame to be presented is waited to open up as described in
Show image frame；
If it is understood that detect the image frame to be presented there are during prompt message, not preserving the image frame to be presented,
The image frame to be presented is can drop, avoids preserving the image frame to be presented to recording in screen file, influences user and normally watch record
Shield the program A in file.Also, after the image frame to be presented is abandoned, the image frame that next frame can be read re-starts prompting
The detection of information, to ensure not including the image frame of display reminding information in the record screen file finally obtained.
After step S203', return and perform the step S202'.
Include the image frame of prompt message by abandoning in the present embodiment, to ensure record screen file that user finally may be viewed by
In not include invalid hint image so that user can swimmingly watch video content.
With reference to Fig. 5, Fig. 5 is the flow diagram of video broadcasting method fourth embodiment of the present invention, based on shown in above-mentioned Fig. 3
Second embodiment, propose the fourth embodiment of video broadcasting method of the present invention.
In the fourth embodiment, after the step S202, the video broadcasting method further includes：
Step S2021：Using the image frame to be presented as current picture frame, and described work as, is read based on preset time axis
Next image frame of preceding image frame；
It is understood that in view of when capturing image frame, in fact it could happen that because of network when video cardton or record screen
It repeats to capture caused by the problems such as unstable, for example, a same image frame has carried out multiple crawl, when user is final in viewing
During the record screen file of generation, pause of the video playing compared with card or video there are the short time can be felt, so as to affect user's
Viewing experience.So previous can be compared with continuous latter when capturing image frame, to find to repeat crawl
Image frame, so as to avoid the problem that above-mentioned repetition captures.
Step S2022：The current picture frame is compared with next image frame；
In the concrete realization, when capturing image frame to program A, it is respectively if grabbing continuous two frame on time shaft
" current picture frame " and " next image frame ", " current picture frame " can be compared with " next image frame ", to judge whether
There is a situation where repeat to capture.
Further, when the current picture frame and next image frame differ, step S2023 is performed.
Step S2023：Using next image frame as the image frame to be presented；
It is understood that if current picture frame is differed with next image frame, show the feelings for not occurring to repeat to capture
Condition can normally preserve image frame, and screen file is recorded with generation.
After step S2023, step S203 is performed.
Further, when the current picture frame is identical with the next image frame, step S20231 is performed.
Step S20231：Abandon next image frame；
It should be understood that when if current picture frame is identical with next image frame, show that the feelings of repetition crawl have occurred
Condition, it may be possible to which video cardton caused by because of network problem continuously grabs the same image frame, if by phase when recording and shielding
Same current picture frame is saved into record screen file with next image frame, and in viewing record screen file video can also occur for user
The situation of interim card.Occur in order to avoid the situation of above-mentioned video cardton, can drop next image frame, only preserve current picture frame,
Without preserving the same image frame.
Step S20232：Using the next frame of next image frame as new next image frame；
After step S20232, step S2022 is performed.
In the concrete realization, in order to ensure the situation of video cardton can all be avoided to occur in subsequent image frame crawl, than
Such as, " current picture frame " be frame 1, " next image frame " be frame 2, since the two is identical, can retention frame 1 abandon frame 2, and read under
