All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The following disclosure provides many different embodiments, or examples, for implementing different structures of the application. In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the application. Furthermore, the present application may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.
The following will describe a video playing method according to the embodiment of the present application in detail with reference to the specific embodiment, as shown in fig. 1, the specific steps are as follows:
s101, detecting a seek instruction in the process of playing a target video.
The seek instruction refers to an instruction triggered by a user by pulling a playing progress bar or other operations for selecting a playing progress (such as clicking a fast forward button for 5 seconds, clicking a fast backward button for 5 seconds, etc.) in the process of playing the target video by the terminal device.
In the embodiment of the application, the seek instruction is detected in real time in the process of playing the target video.
S102, under the condition that the seek instruction is detected, determining the current playing position corresponding to the target video, and determining the target playing position corresponding to the seek instruction.
The current playing position refers to the position of the current playing progress on the target video playing progress bar.
The target playing position refers to the position of the playing progress designated by the seek instruction issued by the user on the target video playing progress bar.
S103, determining the time interval between the current playing position and the target playing position.
In an embodiment of the present application, the specific implementation of determining the time interval between the current playing position and the target playing position may include the following steps:
step A1, determining the total playing time length corresponding to the target video and determining the total length of a playing progress bar of the target video;
a2, determining the interval length of a progress bar between the current playing position and the target playing position;
a3, calculating the ratio of the interval length to the total length;
and step A4, determining the product of the ratio and the total playing duration as the time interval between the current playing position and the target playing position.
The total playing duration refers to the total playing duration of the target video, for example, a 5-minute video, and the total playing duration is 5 minutes.
The total length of the playing progress bar refers to the length of the playing progress bar on the screen of the device. In the application, the corresponding pixels of the playing progress bar on the device screen can be determined first, and then the length of the area occupied by the pixels is calculated as the total length of the playing progress bar.
Since the ratio of the interval length of the progress bar between the current play position and the target play position to the total length of the play progress bar is equal to the ratio of the time interval between the current play position and the target play position to the total length of play, that is, interval length/total length=time interval/total length of play. Thus, the ratio of the interval length to the total length can be calculated and the product of the ratio and the total length of play can be determined as the time interval between the current play position and the target play position. Thus, the interval length of the current playing position and the target playing position in space can be converted into a time interval in time.
And S104, under the condition that the time interval is smaller than or equal to the preset duration, acquiring the image data corresponding to the target playing position from a preset cache, and playing the image data.
In the preset cache, an image frame sequence with preset duration from the current playing position is cached in advance. For example, the playing time corresponding to the current playing position is 1 minute and 30 seconds, and the preset duration is 60 seconds, and then the image frame sequence between 30 seconds and 2 minutes and 30 seconds is cached in the preset cache in advance.
In the preset buffer, image frame buffer is realized but rendering is not performed, and in the application, FBO (Framebuffer Object ) can be used to achieve the purpose. FBO allows rendering results to be stored into texture or rendering buffers without requiring them to be displayed on a screen.
The following is code that implements caching by FBO:
in the application, a timer may be set to execute a task, and the execution frequency of the task is set (for example, the execution frequency is 1 s), and a preset duration is set (for example, 60 seconds), for a picture frame buffer queue in a preset buffer, a minimum buffer unit gp is set, and according to the size of the gp, the picture frame buffer queue is grouped, and each time a buffer is newly added, or a buffer is popped up, where the gp is a minimum unit (for example, each time one image frame, two image frames, or one second image frame sequence, two second image frame sequence, etc.).
The following actions are performed every 1 second:
and correcting an image frame buffer queue in the preset buffer according to the playing time t corresponding to the current playing position. If the starting time of the last buffer unit of the current image frame buffer queue is less than t+60s, then the image frames are buffered one by one, the video gos is taken as a minimum unit, and the starting time of the last buffer unit is greater than t+60s. If the end point of the minimum buffer unit (i.e. the end time of the forefront buffer of the image frame) of the current image frame buffer queue is smaller than t-60s, the forefront part of the image buffer frame is popped up and released one by taking the video gos as a minimum unit until the end time of the forefront buffer of the image frame buffer is larger than or equal to t-60s. In this way, in the preset buffer, a sliding window picture buffer queue which can cover 60s before and after the current playing point t is maintained.
In addition, in the application, the preset time period can be determined by the following steps:
step B1, acquiring a plurality of historical seek instructions corresponding to the target video, wherein the historical seek instructions are instructions issued by a user aiming at the target video and/or the target video with the same type in a preset time period;
step B2, determining a historical target playing position indicated by each historical seek instruction and a corresponding historical current playing position when issuing the historical seek instruction;
step B3, determining a history interval duration corresponding to the history seek instruction based on the history target playing position and the history current playing position;
and B4, calculating an average value of the historical interval duration corresponding to all the historical seek instructions, and determining the average value as the preset duration.
According to the scheme, based on the historical seek instruction issued by the user, the time length (namely the historical interval time length) of hope of fast forward/fast backward when the user issues the historical seek instruction each time can be known, and the average value of the historical interval time lengths corresponding to all the historical seek instructions is determined to be the preset time length. Thus, when a new seek instruction is issued by a user, the hit rate of the image frames in the preset cache can be improved.
Based on the above, when the time interval is less than or equal to the preset duration, the image data corresponding to the target playing position can be obtained from the preset buffer memory, and the image data is rendered to realize the playing of the image data. Therefore, the time for loading and decoding the video can be saved, the time for realizing the seek function is shortened, and the problem of untimely response is solved.
In application, the rendering of image data may be achieved by:

in addition, in the application, after the buffered image data is played, the subsequent video data can be played through the following codes.

As to how to obtain the image data corresponding to the target playing position from the preset buffer, detailed explanation will be made by the following embodiments, which will not be described in detail here.
In yet another embodiment of the present application, the method may further comprise the steps of: and under the condition that the time interval is longer than the preset time length, sending a video loading request to a preset server based on the target playing position so that the corresponding video file is returned by the preset server, and analyzing the video file to obtain image data corresponding to the target playing position. Therefore, when the target playing position indicated by the seek instruction exceeds the data cached in advance in the preset cache, the corresponding image data is requested to be loaded to the preset server so as to realize the seek function.
Furthermore, in yet another embodiment of the present application, the method may further include the steps of:
step C1, determining target playing time corresponding to the target playing position;
step C2, determining a preloading time range corresponding to the target playing position based on the target playing time and the preset duration;
step C3, transmitting a pre-loading request to the preset server based on the pre-loading time range while transmitting the video loading request so as to return a corresponding pre-loading file from the preset server;
and C4, analyzing the preloaded file to obtain preloaded image data, and storing the preloaded image data into the preset cache.
The preloading time range refers to the range between the target playing time and the preset duration and between the target playing time and the preset duration.
In this embodiment, while sending a video loading request to a server, video data (i.e., a pre-loaded file) within a pre-loaded time range is pre-requested to a preset server, and pre-loaded image data obtained by analyzing the pre-loaded file is stored in a preset buffer. Thus, the preloading of partial videos before and after the target playing time is realized.
According to the scheme, the video of the front part and the rear part of the target playing time can be acquired and cached while the image data corresponding to the target playing position is acquired, so that when a user further issues a seek instruction corresponding to the video based on the target playing position, the corresponding image data can be provided in time through the preset cache, the waiting time of the user is reduced, and the user experience is improved.
In the embodiment of the application, a seek instruction is detected in the process of playing a target video, a current playing position corresponding to the target video is determined under the condition that the seek instruction is detected, a target playing position corresponding to the seek instruction is determined, then, a time interval between the current playing position and the target playing position is determined, and under the condition that the time interval is less than or equal to a preset duration, image data corresponding to the target playing position is obtained from a preset cache, and the image data is played. According to the application, the image data pre-cached in the preset cache can be utilized to respond to the seek instruction, and the corresponding image data can be played, so that the time for loading and decoding the video can be saved, the time for realizing the seek function is shortened, and the problem of untimely response is solved.
Referring to fig. 2, a flowchart of an embodiment of another video playing method according to an embodiment of the present application is provided. The flow shown in fig. 2 describes how to obtain the image data corresponding to the target playing position from the preset buffer based on the flow shown in fig. 1. As shown in fig. 2, the process may include the steps of:
s201, acquiring a pre-stored image frame sequence from the preset buffer, and determining a time stamp corresponding to each image frame in the image frame sequence.
In the embodiment of the present application, the preset buffer includes a first buffer and a second buffer, the first buffer stores a first frame sequence, the second buffer stores a second frame sequence, and the specific implementation of obtaining the pre-stored image frame sequence from the preset buffer may include:
and under the condition that the target playing position is positioned before the current playing position, acquiring the first frame sequence from the first buffer memory as the image frame sequence, and under the condition that the target playing position is positioned after the current playing position, acquiring the second frame sequence from the second buffer memory as the image frame sequence.
Here, the preset buffer is divided into two buffer spaces in advance, namely, a first buffer in which video data (i.e., a first frame sequence) of a preset duration before the current play position is buffered in advance, and a second buffer in which video data (i.e., a second frame sequence) of a preset duration after the current play position is buffered in advance. In this way, according to the position of the target playing position relative to the current playing position, half of the frame sequence (i.e. the first frame sequence or the second frame sequence) can be obtained from the preset buffer as the image frame sequence, so that the calculation amount of the subsequent target image frame determination is reduced.
The timestamp corresponding to the image frame refers to the playing time of the image frame in the normal playing process of the target video, for example, the timestamp of the image frame 1 is 6 seconds, which means that the image frame 1 is played in the 6 th second in the normal playing process of the target video.
S202, determining the current playing time corresponding to the current playing position.
S203, determining the target playing time corresponding to the target playing position based on the current playing time and the time interval.
In the embodiment of the application, when the target playing position is in front of the current playing position, the target playing time corresponding to the target playing position is obtained by subtracting the time interval from the current playing time, and when the target playing position is behind the current playing position, the target playing time corresponding to the target playing position is obtained by adding the time interval from the current playing time.
S204, determining the image frame with the corresponding timestamp consistent with the target playing time in the image frame sequence as a target image frame.
S205, determining the image data in the image frame sequence based on the target image frame, wherein the image data is a frame sequence in which the target image frame is arranged first.
S204 to S205 are collectively described below:
in the embodiment of the application, firstly, an image frame with the corresponding time stamp consistent with the target playing time in an image frame sequence is determined as a target image frame, then, the target image frame is used as the image frame arranged at the first position, a frame sequence with a preset length is obtained, and the frame sequence is determined as image data.
The preset length may be specifically set by the user according to the actual requirement, for example, when the minimum buffer unit is 5 seconds of data, the preset length may be a 5 second frame sequence.
Through the flow shown in fig. 2, the target playing time corresponding to the target playing position can be determined based on the current playing time and the time interval corresponding to the current playing position, and then, the image data is determined according to the target image frame with the corresponding time stamp equal to the target playing time in the image frame sequence. Thereby, acquisition of image data is achieved.
