Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment of the invention provides a structural schematic diagram of a system for realizing the embodiments of the invention, which comprises a terminal, wherein the terminal comprises: processor 1110 and memory 1130, wherein the terminals may be mobile terminals such as cell phones, tablet computers, notebook computers, palm top computers, personal digital assistants (PersonalDigitalAssistant, PDA), portable media players (PortableMediaPlayer, PMP), navigation devices, wearable devices, smart bracelets, pedometers, and stationary terminals such as digital TVs, desktop computers, and the like.
As shown in fig. 1, an embodiment of the present invention provides a video playing method. Referring to fig. 1, the method comprises the following steps:
s11, acquiring a first corresponding relation between a video frame and a playing time point in the video to be played under a first video playing rule.
S12, obtaining a second corresponding relation between the video frames in the video to be played and the playing time point under a second video playing rule.
In this embodiment, when playing video, each video frame in the video is displayed frame by frame, and when continuous image changes exceed more than 24 frames (frames) per second, according to the persistence of vision principle, a human eye cannot distinguish a single still picture; it appears as a smooth continuous visual effect.
In this embodiment, because the playing policies of the player cores in different browsers or player clients have differences, the video playing rules are the playing rules set by the different player cores, and for the same timestamp, the frames displayed by different browsers may be different, so that the situation that the video frames corresponding to the same time point are forward or backward one frame occurs, so that the corresponding relationship between the video frames in the video to be played and the playing time point is obtained in this step, that is, the corresponding relationship between the frame numbers of the client or the browser playing the video to be played and the playing time point is obtained.
In this embodiment, the correspondence between the video frames and the playing time points may be obtained by associating the frame numbers of the video frames with the playing time points, or may be obtained by respectively marking the corresponding playing time points on the video frames; the frame numbers of the video frames can be numbers obtained by sequencing according to the playing sequence of the video frames, or numbers configured by a user, each video frame has a corresponding playing time point, and the corresponding relation between the frame numbers of the video frames and each playing time point is obtained in the scheme and can be used for determining at which time point the video frames with each frame number are played.
Specifically, the display duration of each video frame is fixed in the video playing process, for example, 25 frames are displayed per second, each frame is the display time of 0.04 seconds, so in this scheme, the corresponding relationship between the frame number and the display time point of the video frame can be determined according to the number of the frame number and the display duration of the video frame, for example, the frame number of the video frame can be sequentially increased by 1 from 1, the display time point of the nth frame is the display time of the (n-1) x video frame, and for the frame number of the video frame which is not increased by a fixed value, the corresponding display time point needs to be determined corresponding to each frame number, and the corresponding relationship is generated and can be stored through a table, an array or a dictionary.
S13, when the starting time point of the video to be played is selected, generating a time point to be played through the starting time point according to the first corresponding relation and the second corresponding relation, and playing the video to be played at the time point to be played when the video to be played is played; the video frames of the video to be played at the time point to be played under the second video playing rule are consistent with the video frames of the video to be played at the starting time point under the first video playing rule.
In this embodiment, when the video to be played is played on different browsers or players, the same time point is selected on the progress bars of the different browsers or players, and the played video frames may appear differently due to different player cores of the browsers or players, which may cause deviation for the user, for example, for the added map advertisement on the video to be played, the situation of wearing the upper is easy to appear, for example, such a video, a teacher comes out from the third class, then goes through the corridor, and enters the second class.
There are 3 scenes in this video:
and (3) a step of: three years and one shift (assuming the corresponding time is video frame 0 to frame 50);
And II: corridor (51 st to 100 th frames);
thirdly,: three-grade class two (101 frames to 200 frames);
at this time, the video is connected to a new advertisement, we need to paste an advertisement poster on the wall of the corridor, that is, the advertisement appears from 51 st frame to 100 th frame, if the user does not want to wear the wall, two conditions must be satisfied, the 51 st frame to 100 th frame of the picture played by any browser must be the corridor, and the advertisement must appear between the 51 st frame and 100 th frame.
For the first browser or player, when selecting the corridor segment, 51-100 is marked as a corridor, i.e. the map advertisement is played at the time points corresponding to the 51 st frame and the 100 th frame, now, because the cores of the players between different browsers are inconsistent, when the first browser or player holds the mark to play, the situation that the advertisement leaks out in advance and ends in advance can occur, for example, under the condition that the playing time point corresponding to the 51 st frame is the picture of the video frame of the 50 th frame under the other browser or player, at the moment, a suspended advertisement board is visually seen in a class room of three grades, and no advertisement is seen in the 100 th frame, because the advertisement is ended when the video frame of the 99 th frame, the advertisement flash disappears, and only a white wall is left, so that the situation of wearing is caused.
The difference of the playing frame numbers is caused by different playing strategies of player kernels in different browsers or players, and for the same time stamp, the pictures displayed by different browsers or players may be different, and the situation of one frame forward or one frame backward occurs, which does not affect the experience of the user for watching the video, however, once the video needing to be subjected to the map advertisement occurs, the situation that the time points set during the playing of the map advertisement cannot be matched with each time point easily occurs.
In this embodiment, aiming at the above situation, the method is to ensure that when the map advertisement appears, the corresponding video frames are corresponding to the corresponding video frames, and the first corresponding relation and the second corresponding relation are used to generate the time point to be played based on the start time point, so that the video frames to be played at the time point to be played under the second video playing rule are consistent with the video frames to be played at the start time point under the first video playing rule, and of course, the video frames to be played at the time point to be played under the first video playing rule are consistent with the video frames to be played at the start time point under the second video playing rule.
Moreover, the video frames of the video to be played are not only deviated due to the rendering mode of the browser or the player, but also display deviation is caused by the combination of the time point selected by the user and the rendering mode, for example, the playing time point of the video frames is 0.04 second, 0.08 second and 0.12 second.
The browser or player in the above scheme is only used for illustration, and the video player and other video playing devices have their own rendering rules, so that the above problems can occur in different video playing devices, and the scheme can be applied.
In this embodiment, the video to be played is played according to the adjusted time point to be played, so that the video frames finally played by different browsers, players or video devices at the same time point to be played are all the same video frame, and the situation that the user watching experience is affected or the situation that the user watching experience is affected is avoided when the video after further processing is played.
In this embodiment, by acquiring the correspondence between the video to be played and the playing time point under different video playing rules, when the starting time point is selected for the video to be played, the time point to be played corresponding to the starting time point is determined according to the correspondence under different video playing rules, so that the video frames corresponding to the same time point when the video to be played is played under different video playing rules are consistent, and therefore, the mapping advertisement or other operations of the user on the video can be kept consistent under all video playing environments.
Specifically, taking the mapping advertisement as an example, a worker sets the mapping advertisement for the video in the background according to the corresponding relation between the frame number and the playing time point in the preset standard, for example, the mapping advertisement is set on the 51 st frame to the 99 th frame, at this time, the worker sets the mapping advertisement to play between the playing time point corresponding to the 51 st frame and the playing time point corresponding to the 99 th frame for 4.96 seconds, after the configuration is completed, in the video playing device, the playing time point of the first frame video frame is 0 seconds, which results in that the 52 th frame video frame is played for 2.04 seconds, that is, the frame number to be played selected when the mapping advertisement is played in the S12 is the 52 th frame, and the mapping advertisement is played between the 52 th frame and the 100 th frame, so at this time, the frame number to be played is adjusted according to the scheme, whether the playing time point of the mapping advertisement is 2.04 seconds to 4.96 seconds, and the video to be played is played or the 51 st frame to the 99 th frame video frame.
In this embodiment, before obtaining the correspondence between the frame number of each video frame in the video to be played and the playing time point, the playing method further includes: acquiring a video to be processed; transcoding the video definition of the video to be processed, so that the definition of the video to be processed is converted into the preset video definition, and the video to be played is obtained.
In this embodiment, the preset video definition may be the lowest definition or the video definition set by the user, and the image size of the video frame displayed by the video with lower definition is also smaller, so that the problem of too slow loading caused by too large video frame size can be effectively avoided, and the video loading efficiency is improved.
Specifically, the obtaining a first correspondence between video frames in the video to be played and the playing time point under the first video playing rule may be obtaining a correspondence between a frame number of each video frame in the video to be played and the playing time point under the first video playing rule as the first correspondence; the obtaining of the second correspondence between the video frames in the video to be played and the playing time point under the second video playing rule may be obtaining the correspondence between the frame number of each video frame in the video to be played and the playing time point under the second video playing rule as the second correspondence.
As shown in fig. 2, in this embodiment, the obtaining a first correspondence between a video frame and a playing time point in a video to be played under a first video playing rule includes the following steps:
s21, acquiring a first frame rate and a first playing duration of a video to be played under a first video playing rule.
S22, obtaining a first total frame number of the video to be played according to the first frame rate and the first playing duration.
In this embodiment, the total frame number of the video to be played is calculated according to the frame rate and the playing duration of the video to be played, and the total frame number of the video to be played can be obtained by directly multiplying the frame rate and the playing duration, or of course, the total frame number of the video to be played can be counted in a counting manner, so as to avoid the problem that errors occur in the frame number due to the fact that the video is inserted and extracted.
S23, acquiring a first start frame number of a first frame video frame of a video to be played and a first end frame number of a last frame video frame of the video to be played based on a first video playing rule.
S24, according to the first playing time length and the first total frame number, a first time interval of a playing time point of any adjacent video frame in the video to be played is obtained.
In this embodiment, not only the time interval of the playing time point of the adjacent video frame of the video frame to be played can be determined by the playing time length and the total frame number of the video to be played, but also the time interval of the adjacent video frame can be determined according to the frame rate of the video to be played.
S25, obtaining the corresponding relation between the frame number of each video frame and the playing time point based on the first video playing rule according to the first starting frame number, the first ending frame number, the first playing time length and the first time interval of the video to be played.
In this embodiment, after determining the initial frame number, the end frame number, the playing duration and the time interval, the correspondence between each frame number and the playing time point is determined. Similarly, the corresponding relationship between the frame number of each video frame in the video to be played and the playing time point under the second video playing rule can be determined in the same manner, and the scheme is not described herein again.
As shown in fig. 3, in a specific embodiment, the selecting a starting time point for the video to be played in S12 includes the following steps:
s31, receiving a first operation corresponding to a preselected time point of a video to be played.
S32, taking the video frames with the preset number, which are adjacent to the preselected time point at the playing time point, as the video frames to be selected according to the first operation, and displaying.
S33, receiving a second operation of selecting any video frame to be selected, and taking a playing time point corresponding to the video frame to be selected by the second operation under a second video playing rule as a starting time point.
In this embodiment, the first operation includes, but is not limited to, operations of sliding, clicking, and the like, and the second operation includes, but is not limited to, operations of clicking, dragging, and the like, and the first operation and the second operation may be operations of a user on the video playing device, or may be operations for pre-configuration, and an operation triggered automatically when a condition is satisfied.
In this embodiment, the operation of clicking the to-be-selected playing time point by the user is obtained, and the video frames adjacent to the to-be-selected playing time point at the playing time point are used as to-be-selected video frames, so that the user can intuitively observe each video frame and select a video frame required by the user, for example, for a screen recording user, because it is very difficult to select the video frame of the self-heart instrument by sliding the time bar, the time consumed by the user for selecting the video frame can be effectively reduced, and the user can intuitively see the video frame to be selected.
In a specific embodiment, the scheme of selecting video frames in combination with the present scheme may not only select video frames according to the above scheme, but also: and receiving the input frame number as a frame number to be played, and taking a video frame corresponding to the frame number to be played as a video frame to be selected.
As shown in fig. 4, in a specific embodiment, the selecting a starting time point for the video to be played in S12 includes the following steps:
s41, receiving a third operation corresponding to a preselected time point of the video to be played.
S42, acquiring the video frame with the shortest time interval between the playing time point and the preselected time point as the video frame to be selected.
In this embodiment, the third operation includes, but is not limited to, operations such as sliding, clicking, and the like, and may also be that the user directly inputs the time point as the time point for playing to be selected, which is not described herein again.
