Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The video playing method provided by the present disclosure may be applied to the application environment shown in fig. 1. Wherein the terminal 110 interacts with the server 120 through the network. The terminal 110 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 120 may be implemented by an independent server or a server cluster formed by a plurality of servers.
The terminal 110 detects a playing progress of video data of a target video in a playing process of the target video, wherein the video data of the target video is downloaded video data, and when it is detected that the video data of the target video is played completely, the video data is read from an initial position of the video data of the target video and the read video data is played, so that the problem of blocking is solved, and a user can visually see a smoothly played video.
Fig. 2 is a flowchart illustrating a video playing method according to an exemplary embodiment, where as shown in fig. 2, the video playing method is applied to the terminal 110 of fig. 1, and includes the following steps:
in step S21, during the playing process of the target video, the playing progress of the video data of the target video is detected, wherein the video data of the target video is the downloaded video data.
The playing schedule may be a playing time length of the downloaded video data, a number of played data, and the like, and is not limited herein.
The video playing is to load the downloaded video data into the memory for playing, so that detecting the playing progress of the video data of the target video is equivalent to detecting the playing duration of the downloaded video data, and/or the amount of the playing data, and the like.
In step S22, when it is detected that the video data of the target video is played, the video data is read from the start position of the video data of the target video, and the read video data is played.
In the embodiment of the present disclosure, for convenience of understanding, it is assumed here that the number of downloaded video data is 2M, and the video data is re-read starting from 0 and played.
According to the video playing method, in the playing process of the target video, the playing progress of the video data of the target video is detected, wherein the video data of the target video is downloaded video data, when the video data of the target video is detected to be played completely, the playing jam problem is shown, at the moment, the video data is read from the initial position of the video data of the target video, and the read video data is played, so that the jam problem is solved, and a user can visually see the smoothly played video.
In an optional embodiment, the method further comprises:
and when the quantity of the video data of the target video exceeds a first preset threshold value, playing the target video.
In the embodiment of the present disclosure, the running of the program (i.e., playing of the video) needs to be performed in the memory, and as long as the program is running, the CPU loads the data to be processed into the memory for processing. It can write (store) or read (fetch) data from any one of the designated addresses at any time. Because of its volatile nature, it can be used to temporarily store data in the CPU. When the memory is a random access storage device, the video data can be stored in the memory from the server in two ways, the first way is to Cache the video data from the server to the memory (namely, a Cache memory), and the second way is to Cache the video data from the server to the memory (namely, a Buffer register).
In the embodiment of the present disclosure, a threshold value is preset, and the threshold value may be determined according to the amount of the entire data of the target video, for example, the threshold value is set to 10% of the amount of the entire data. The threshold value may not be determined according to the whole data quantity of the target video, but a threshold value is directly determined according to the experience of playing the video.
In the embodiment of the present disclosure, before playing the target video, it is required to detect whether the amount of video data of the target video exceeds a first preset threshold, specifically, a Buffer value or a Cache value may be detected and monitored, and when the amount of video data of the target video exceeds the first preset threshold, the target video is played. If the cached video is particularly short, for example, one frame or two frames, etc., the particularly short video data will be repeatedly played during the loop playing, and the video appears to be blocked in the appearance, so that the blocking in the video playing process is reduced by setting the judgment threshold, and the user experience is improved.
In an optional embodiment, the method further comprises: responding to a video playing request, storing the downloaded and acquired video data into a first storage device, and caching the video data into a second storage device; in step S21, detecting a playing progress of the video data of the target video includes:
the remaining amount of video data in the first storage device is detected.
The first storage device is a random access storage device, which is a bridge for communicating with the CPU, such as a server or an external storage device, and the first storage device is an internal memory for directly exchanging data with the CPU. It can be read and written at any time, and is fast, usually used as temporary data storage medium of operating system or other running program.
The second storage device is an external storage device, and refers to a storage except for the first storage device and the CPU storage, and the second storage device can still store data after being generally powered off and is used for storing programs and data which are not used temporarily. Common external storage devices include hard disks, floppy disks, optical disks, U-disks, and the like.
In the embodiment of the present disclosure, for convenience of understanding, it is illustrated herein that, for example, the number of downloads of video data of a target video (i.e., downloaded video data) is 2M, during the playing process of the target video, it may be detected that the playing progress (assuming that the playing progress is the number of data) of the target video is 1M, and then the remaining amount of the video data in the first storage device is 1M.
In an alternative embodiment, step S22 includes:
and when the video data of the target video is detected to be played completely, reading the video data from the initial position of the video data stored in the first storage equipment, and playing the read video data.
In the embodiment of the present disclosure, the first storage device stores data that can be stored in a small amount, for example, the first storage device stores data that can be stored in 2M, and if the video data of the target video (i.e., the downloaded video data) is 4M, when playing 3-4M, the video data of the target video will delete the video data of 1-2M cached by the first storage device; if the video data of the target video (i.e., the downloaded video data) is 1M or 2M, when the video data of the target video is played, the 1-2M video data stored in the first storage device may not be deleted, and the video data may be read from the start position of the video data stored in the first storage device and played.
In an alternative embodiment, step S22 includes:
when the video data of the target video is detected to be played completely, the video data stored in the second storage device is read to the first storage device, so that the player reads the video data from the starting position of the video data read from the second storage device by the first storage device and plays the read video data.
In an alternative embodiment, reading the video data stored by the second storage device to the first storage device comprises: and detecting the storage amount of the video data of the target video on the first storage device, and reading the video data stored in the second storage device to the first storage device when the storage amount is smaller than a second preset threshold value.
In the embodiment of the present disclosure, because the first storage device stores a small amount of data in a short period of time, when it is detected that the video data of the target video is completely played, it is necessary to detect the storage amount of the video data of the target video on the first storage device, and when the storage amount is smaller than the second preset threshold, it indicates that the storage amount is too small, the video data of the target video on the first storage device is not played, the video data stored in the second storage device is read to the first storage device (i.e., the data of the external storage device is loaded into the memory), and the player reads the video data from the start position of the read video data and plays the read video data.
In an optional embodiment, before detecting the playing progress of the video data of the target video in the playing process of the target video in step S21, the method further includes:
detecting whether video data of a target video is completely downloaded;
and if the video data of the target video is not completely downloaded, executing a step of detecting the playing progress of the video data of the target video in the playing process of the target video.
In the embodiment of the present disclosure, the terminal may know whether all video data of the target video has been downloaded, and then step S21 and the subsequent steps are not executed. For convenience of understanding, for example, if the entire video data of the target video is 2M and the cacheable capacity stored in the first storage device is 3M, the entire video data of the target video can be cached in the first storage device, and if the video data of the target video is completely downloaded, the video is not jammed during playing, and the step S21 and the subsequent steps are not required to be executed. If the video data of the target video is not completely cached, video blocking may occur in the playing process, and it is required to detect the playing progress of the video data of the target video in the playing process of the target video, where the video data of the target video is downloaded video data, and when it is detected that the video data of the target video is completely played, it indicates that the playing blocking occurs, and at this time, the video data is read from the initial position of the video data of the target video and the read video data is played, so that the blocking problem is solved, and a user can visually see a video which is smoothly played.
In an optional embodiment, the method further comprises: acquiring video information of a target video; step S22 includes:
when the video data of the target video is detected to be played completely and the playing progress of the video information of the target video is not matched with that of the video data of the target video, reading the video data from the initial position of the video data of the target video and playing the read video data.
Wherein the video information of the target video comprises the whole duration or the data amount of the target video. In the embodiment of the present disclosure, the video information of the target video needs to be matched with the playing progress of the video data, for example, if the entire duration of the target video is 2 minutes, and the playing progress when the video data of the target video is played is 1 minute, it is proved that the video data of the target video is not completely cached, at this time, the video data of the target video is played completely to indicate that a playing stuck problem occurs, and the video data needs to be read from the initial position of the video data of the target video and played, so that the stuck problem is solved, and a user can visually see a video that is smoothly played.
In an optional embodiment, the header file of the video data includes metadata, and the metadata may be moov, and the metadata moov may implement video playing while downloading during online playing. The header file of the video data comprises metadata moov, and the metadata moov is at the head and is loaded and read to the metadata moov firstly, so that a picture can be immediately displayed.
In the embodiment of the disclosure, when it is detected that the video data of the target video is played, the video data is read from the initial position of the video data of the target video, and the metadata moov is at the head, the metadata moov is loaded and read first, so that a picture can be displayed immediately, seamless connection of the video during the time of blocking is realized, and the problem of the existing blocking is solved.
In an optional embodiment, when the entire video data of the target video is completely played, or the user actively exits from playing the target video (for example, if the interface has a corresponding closing control, and a touch operation of the user on the closing control is monitored, the playing of the target video is exited), the scheme in the embodiment of the present disclosure is not executed any more.
It should be understood that, although the steps in the flowchart of fig. 2 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in fig. 2 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least a portion of the other steps or stages.
