Based on the hardware structure, the embodiment of the video playing method is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a video playing method according to a first embodiment of the present invention.
In a first embodiment, the video playing method includes the following steps:
step S10: when a current video is requested through a VOD technology, obtaining buffer data of the current video, and judging whether the data volume of the buffer data is less than or equal to a preset threshold value or not;
it is understood that the execution subject is a smart tv. When a user plays a video program by using the smart television, because the smart television plays the video by applying the VOD technology, when the network speed is poor, the playing is suspended to buffer the video. However, if the network environment is unstable and the network speed is extremely low, the video is finally played through the video buffering, which causes the video to be in a stuck state all the time, and the switching is quickly performed between the state of "pausing and buffering the video" and the state of "playing the buffered video", which causes the user experience of watching the video to be poor. In view of the above reasons, when the network speed is relatively low, the video to be played is recorded, and the picture of the recorded screen is played to realize the playing of the video. Since the VOD technology is an online viewing mode, the VOD technology cannot provide a local download function, and the VOD technology cannot provide a large storage space, the play of the video is finally realized by a screen recording mode, and the VOD technology can be well integrated.
In a specific implementation, for example, when the smart television plays a video of a program a through a VOD technology, if the minimum network speed for ensuring that the program a can be smoothly played is 500KB/S, and the real-time network speed when the program a is played is 400KB/S, since the real-time network speed is less than the minimum network speed, it may be determined whether the data amount of the buffer data of the program a is less than or equal to the preset threshold. If the data volume of the buffer data of the program a is 2 seconds of video and the preset threshold is 10 seconds of video, it can be determined that the program a cannot be smoothly played because the data volume of the buffer data is less than or equal to the preset threshold.
Step S20: and when the data volume of the buffer data is less than or equal to the preset threshold value, recording the screen of the current video to obtain a screen recording file, and playing the screen recording file.
It should be understood that when the a program cannot be smoothly played, the a program may be recorded, and a local video of the a program is generated through the recording, and a user may view the program by directly opening the local video. Because the VOD technology can not provide the local downloading function, the screen recording operation can be carried out on the intelligent television applying the VOD technology, the normal playing of the video can be well realized, and the situation that the video is frequently buffered and blocked is avoided.
In the embodiment, the current video is recorded when the video cannot be smoothly played, so that the video can be smoothly watched by playing the local screen recording video when the VOD technology cannot guarantee smooth playing of the video, and the technical problem that the video cannot be normally played due to poor network speed environment when the VOD technology is applied to video spot playing is solved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a video playing method according to a second embodiment of the present invention, and the video playing method according to the second embodiment of the present invention is proposed based on the first embodiment shown in fig. 2.
In the second embodiment, the step S20 specifically includes:
step S201: when the data amount of the buffer data is smaller than or equal to the preset threshold value, acquiring the frame rate of the current video;
it can be understood that, when a current video, that is, an a program, is recorded, it is considered that video information and audio information exist in the a program at the same time, and in order to prevent a situation that a video picture is not synchronized with sound when a finally obtained recording file is played, the recording file can be obtained by aligning timestamps when the recording file is generated, so that synchronization of the video picture and the sound is ensured.
In a specific implementation, when the data amount of the buffer data of the program a is 2 seconds of video, the video that is smaller than the preset threshold value, that is, 10 seconds, will first obtain the play frame rate of the program a.
Step S202: capturing the current video according to the frame rate to capture a picture frame to be displayed;
it can be understood that, when the playing frame rate of the a program is obtained, the a program is grabbed based on the playing frame rate. The frame rate is used for recording the display frame number per second, the video inherent frame rate of the program A is obtained, the program A is grabbed based on the inherent frame rate, the definition of the video data of the obtained screen recording file and the video data of the program A which is not recorded during normal playing can be guaranteed to be the same, if the program A is not grabbed according to the inherent frame rate, the screen recording file is grabbed only by adopting the frame rate smaller than the inherent frame rate, and the finally grabbed screen recording file can be played unsmoothly or with lower definition.
Step S203: saving the picture frame to be displayed and recording a time stamp of the picture frame to be displayed;
step S204: and acquiring audio data corresponding to the picture frame to be displayed based on the timestamp, combining the picture frame to be displayed and the audio data to obtain a screen recording file, and playing the screen recording file.
It should be understood that after the frame rate of the a program is obtained, the timestamp of the currently obtained frame to be displayed may be recorded, and the audio data corresponding to the frame to be displayed is obtained based on the timestamp, so as to ensure that the frame and the audio are synchronous, and a situation that the frame precedes the audio or the audio precedes the frame does not occur when the screen recording file is played.
Further, the step S202 may further include, in response to a frame rate adjustment instruction input by a user, acquiring preset frame rates that are less than or equal to the frame rate of the current video, and selecting a target frame rate from the preset frame rates according to the frame rate adjustment instruction; and capturing the current video according to the target frame rate to obtain a picture frame to be displayed.
It will be appreciated that the screen recording may be taken into account when the network speed is poor or unstable so that the user may eventually watch the program a smoothly. However, when the network speed is slow but the frame rate of the program a is too high, if the frame of the picture to be displayed is still captured according to the larger frame rate of the program a, the time for finally acquiring the complete screen recording file may be long. Therefore, in consideration of the difference of the network speed, the user can freely select the frame rate of the captured frame to determine the definition and the time consumption of the acquired screen recording file, because the larger the frame rate of the captured video is, the higher the definition of the finally acquired screen recording file is, but the network speed requirement is higher and the time consumption is longer.
In a specific implementation, when the inherent frame rate of the acquired program a is 100, a plurality of selectable frame rates from 0 to 100 may be displayed on an operation interface of the smart television for the user to select. If the user selects the target frame rate by clicking a physical key or a virtual key of the smart television or a remote controller matched with the smart television, for example, the target frame rate can be selected to be 50 from a plurality of selectable frame rates from 0 to 100, the program a can be captured according to the target frame rate 50, and compared with the capture of the program a through the inherent frame rate 100, if the network speed is kept unchanged, the screen recording file captured according to the target frame rate 50 has lower definition but shorter time consumption.
In this embodiment, the corresponding audio is determined based on the timestamp of the picture frame, so that when the screen recording file obtained by finally combining the picture frame and the audio is played, the picture and the sound are not synchronized. In addition, the definition of the screen recording file can be well ensured by capturing the picture frame based on the frame rate of the current video.
Referring to fig. 4, fig. 4 is a flowchart illustrating a video playing method according to a third embodiment of the present invention, and the video playing method according to the third embodiment of the present invention is proposed based on the second embodiment shown in fig. 3.
In a third embodiment, after the step S202, the video playing method further includes:
step S202': checking whether prompt information is displayed in the frame of the picture to be displayed;
it can be understood that, during the process of capturing and saving a frame, an invalid frame may be captured, and specifically, there may be prompt information in the captured frame, for example, there are prompt words "capturing in the middle of the frame, please wait slightly" buffering "and so on in the center of the frame, so as to represent that the frame cannot be captured normally due to a slow network or a player. However, if the screen in which the cue word exists is also recorded into the finally generated screen recording file during the screen recording process, the screen including the cue word does not exist in the video screen of the program a, and the recording of the screen recording file also affects the normal watching of the program a by the user, so the screen including the cue word can be not recorded into the screen recording file.
In a specific implementation, after a to-be-displayed picture frame of a program a is captured, whether prompt information exists in the to-be-displayed picture frame is detected, and if the prompt information does not exist, the to-be-displayed picture frame is stored.
And executing step S203 when the prompt information is not displayed in the frame of the picture to be displayed.
Further, after the step S202', the video playing method further includes:
and executing step S203' when the prompt information is displayed in the frame of the picture to be displayed.
Step S203': discarding the picture frame to be displayed, and taking the next frame of the picture frame to be displayed as the picture frame to be displayed;
it can be understood that, if it is detected that the frame to be displayed has the prompt information, the frame to be displayed is not stored, and the frame to be displayed can be discarded, so that the situation that the user normally watches the program a in the screen recording file is influenced by storing the frame to be displayed in the screen recording file is avoided. And after discarding the frame to be displayed, reading the frame of the next frame to detect the prompt information again, so as to ensure that the finally obtained screen recording file does not include the frame displaying the prompt information.
After step S203', the process returns to the step S202'.
In this embodiment, the picture frame including the prompt information is discarded, so as to ensure that the recording file that can be finally viewed by the user does not include an invalid prompt picture, so that the user can smoothly view the video content.
Referring to fig. 5, fig. 5 is a flowchart illustrating a video playing method according to a fourth embodiment of the present invention, and the video playing method according to the fourth embodiment of the present invention is proposed based on the second embodiment shown in fig. 3.
In a fourth embodiment, after the step S202, the video playing method further includes:
step S2021: taking the picture frame to be displayed as a current picture frame, and reading a next picture frame of the current picture frame based on a preset time axis;
it can be understood that, in view of repeated capturing caused by the problems of video blocking or unstable network during screen recording when capturing the picture frames, for example, when a user views a finally generated screen recording file, the user may feel that video playing is blocked or the video is paused for a short time, thereby affecting the viewing experience of the user. Therefore, when capturing the frame, the previous frame can be compared with the continuous next frame to find the repeatedly captured frame, thereby avoiding the above-mentioned problem of repeated capture.
Step S2022: comparing the current picture frame with the next picture frame;
in a specific implementation, when capturing frame frames for the program a, if two consecutive frames on the time axis are captured as a "current frame" and a "next frame", respectively, the "current frame" and the "next frame" may be compared to determine whether a repeated capture condition occurs.
Further, when the current frame is different from the next frame, step S2023 is performed.
Step S2023: taking the next picture frame as the picture frame to be displayed;
it can be understood that if the current frame is different from the next frame, it indicates that no repeated capture occurs, and the frame can be normally saved to generate a screen recording file.
After step S2023, step S203 is executed.
Further, when the current picture frame is the same as the next picture frame, step S20231 is performed.
Step S20231: discarding the next picture frame;
it should be understood that if the current frame is the same as the next frame, indicating that a video jam may occur due to a network problem, the same frame is continuously captured during screen recording, and if the same current frame and the next frame are both stored in the screen recording file, the user may also have a video jam while viewing the screen recording file. In order to avoid the video pause, the next frame may be discarded, and only the current frame is saved, and the same frame is not needed to be saved.
Step S20232: taking a next frame of the next picture frame as a new next picture frame;
after step S20232, step S2022 is performed.
In a specific implementation, in order to ensure that video blocking can be avoided in subsequent frame capture, for example, the "current frame" is frame 1, and the "next frame" is frame 2, since the two frames are the same, frame 1 can be retained and frame 2 can be discarded, and the next frame of the next frame can be read as the next frame, that is, "next frame" is frame 3, and the action of comparing frame 1, which is the current frame, and frame 3, which is the next frame, is executed again, so as to ensure that video blocking can be avoided in subsequent frame capture.
Further, the step S201 may further include: when the data volume of the buffer data is less than or equal to the preset threshold value, recording the current playing progress of the current video; and modifying the preset starting timestamp of the current video into the timestamp corresponding to the current playing progress, and acquiring the frame rate of the current video.
It is to be understood that, in order to speed up the time for the user to acquire the screen recording file, in view of the implementation scenario of the present embodiment, when the current video is requested by the VOD technology, the screen recording operation is taken due to too little buffer data to ensure that the user can watch the video smoothly, indicating that the user may have watched a part of the long video. For example, if the program a requested by the user is a video with a duration of 120 minutes, and the current playing progress of the program a is recorded to be 50 minutes, which indicates that the user has watched the video content of the first 50 minutes, considering that the network environment is poor and the user wants to watch the program faster, the video of the last 70 minutes can be directly recorded, so as to reduce the time consumed by recording the screen. Therefore, the preset starting timestamp of the program a can be modified from the 0 th minute time to the 50 th minute time, so that for the subsequent screen recording operation, the screen recording object is a video from the 50 th minute time to the 120 th minute time instead of the video from the 0 th minute time to the 120 th minute time, and the speed of acquiring the screen recording file can be increased.
In the embodiment, the current picture frame is compared with the next picture frame to avoid repeated frame numbers, so that the situation that the video is blocked can be avoided in the capturing process of the picture frames.
Furthermore, an embodiment of the present invention further provides a computer-readable storage medium, where a video playing program is stored on the computer-readable storage medium, and when executed by a processor, the video playing program implements the following operations:
when a current video is requested through a VOD technology, obtaining buffer data of the current video, and judging whether the data volume of the buffer data is less than or equal to a preset threshold value or not;
and when the data volume of the buffer data is less than or equal to the preset threshold value, recording the screen of the current video to obtain a screen recording file, and playing the screen recording file.
Further, the video playing program, when executed by the processor, further implements the following operations:

Further, the video playing program, when executed by the processor, further implements the following operations:
and when the prompt information is displayed in the picture frame to be displayed, discarding the picture frame to be displayed, taking the next frame of the picture frame to be displayed as the picture frame to be displayed, and returning to execute the step of checking whether the prompt information is displayed in the picture frame to be displayed.
Further, the video playing program, when executed by the processor, further implements the following operations:
taking the picture frame to be displayed as a current picture frame, and reading a next picture frame of the current picture frame based on a preset time axis;
comparing the current picture frame with the next picture frame;
and when the current picture frame is different from the next picture frame, taking the next picture frame as the picture frame to be displayed, storing the picture frame to be displayed, and recording the time stamp of the picture frame to be displayed.
Further, the video playing program, when executed by the processor, further implements the following operations:
discarding the next picture frame when the current picture frame is the same as the next picture frame;
and taking the next frame of the next picture frame as a new next picture frame, and returning to execute the step of comparing the current picture frame with the next picture frame.
In the embodiment, the current video is recorded when the video cannot be smoothly played, so that the video can be smoothly watched by playing the local screen recording video when the VOD technology cannot guarantee smooth playing of the video, and the technical problem that the video cannot be normally played due to poor network speed environment when the VOD technology is applied to video spot playing is solved.
