Example one
With reference to fig. 1, an embodiment of the present invention provides a video playing method, including:
s01 detecting that the current segment of buffer data of the video being played is completely downloaded;
specifically, downloading the buffered data of the video includes two cases: 1, after the video is triggered to be played, the video starts to download all buffer data of the video (aiming at a short video, namely a short video, an internet content transmission mode is adopted, and generally, the video transmission content with the time length within 5 minutes is adopted); 2, after the video is triggered to be played, the video starts to download the first segment of buffer data of the video, and then continues to download other segments of buffer data along with the playing process of the video (for a long video, in this embodiment, for a non-short video). In the case of the 1 st scenario, in step S01, after the terminal detects that the downloading of all the buffer data of the video being played is completed, if an instruction to play the next video is not received at this time, the terminal enters into the downloading gap time (network bandwidth idle time); wherein the current segment buffer data corresponds to the entire buffer data of the video. In case 2, in step S01, when the terminal detects that the current segment of the buffer data of the video being played has been downloaded, the downloading time point of the next segment of the buffer data is not reached, and the instruction for playing the next segment of the video is not received, entering the downloading gap time; the current segment of buffer data corresponds to the buffer data of the current playing content of the video being played, if the current segment of buffer data corresponds to the last segment of buffer data of the video being played, when the segment of buffer data is completely downloaded, if an instruction for playing the next segment of video is not received at the moment, the downloading gap time is entered.
S02 downloading the start playing segment buffer data of the video to be played in advance;
in step S01, when it is detected that the current segment of buffer data of the video being played has been completely downloaded, i.e. entering the download gap time, the terminal will switch into the pre-download of the start segment of buffer data of the video to be played. In step S02, the start segment buffer data of the pre-downloaded video to be played is buffer data enough for the start segment in the pre-downloaded video to be played. In this embodiment, the buffer data of the video to be played is pre-downloaded by using the download gap time, and only the play start segment part is pre-downloaded, so that the play start segment buffer data of the video to be played is pre-downloaded while the resources of the download gap are effectively used, thereby increasing the play start speed of the video to be played when the video to be played is switched in, that is, reducing the time required by the play start of the video to be played, and reducing the time for a user to wait for watching the video to be played. Further, in step S02, the pre-downloaded part is only for the start-up segment buffer data, which saves the flow of the pre-download by the user (the buffer data of the whole video is not pre-downloaded completely) while increasing the start-up speed, and also reduces the buffer pressure (the start-up segment buffer data only occupies a small part of the buffer data of the whole video). In step S02, a determining step is included, which determines whether the buffering data of the pre-downloaded video to be played is enough to start playing, and if so, stops the pre-download task of the video to be played, specifically, in step S02, only the buffering data of the start playing segment of the video to be played is pre-downloaded.
In this embodiment, for the 1 st case (short video) of downloading the buffer data of the video, step S01 detects that the current segment of buffer data of the video being played has been completely downloaded, and when the downloading gap is entered, the terminal will request to pre-download the start segment of buffer data of the video to be played, and store the buffer data locally.
Further, in this embodiment, for the case 2 (long video) of downloading the buffer data of the video, after the step S01 detects that the downloading of the buffer data of the current segment of the video being played is completed, the method further includes the steps of:
determining the downloading time point of the next section of buffer data of the video being played according to the downloading time length and the playing time length of the current section of buffer data;
determining that the downloading time point arrives, and stopping downloading the start-up buffer data if the start-up buffer data does not complete the pre-downloading;
and downloading the next section of buffer data.
In this case, since the buffering data of the playing video is buffered in multiple segments, the downloading time point of the next segment of buffering data of the playing video is determined according to the downloading time (related to the current network state) and the playing time of the current segment of buffering data, and the starting segment of buffering data of the video to be played is pre-downloaded by using the downloading gap between the time point when the current segment of buffering data finishes downloading and the time point when the next segment of buffering data starts downloading. The pre-downloading task of the buffer data of the play-starting segment of the video to be played is influenced possibly due to poor current network state or when the user accelerates the playing of the current segment of the video being played, the judgment needs to be carried out according to the downloading time point of the next segment of the buffer data of the video being played, when the downloading time point of the next segment of the buffer data of the video being played arrives, the pre-downloading task of the buffer data of the play-starting segment of the video to be played needs to be paused, and the downloading of the next segment of the buffer data of the video being played is started.
Furthermore, when the pre-download task is suspended for the start-play segment buffer data of the video to be played, after the next segment of buffer data is downloaded, the method further includes the following steps:
judging whether the current network state is a first network state, if not, marking the start playing segment buffer data as a stop state;
if so, detecting the downloading speed of the current network, judging that the downloading speed is greater than a preset speed value, if so, continuing to download the start playing segment buffer data, otherwise, marking the start playing segment buffer data as a stop state.
The network states comprise 2G, 3G, 4G, Wifi and the like, the first network state is a Wifi state, when the next section of buffer data of a video being played is downloaded and enters a downloading gap, the terminal judges the current network state, and when the requirement of the first network state is not met, the pause task of the buffer data of the playing starting section of the video to be played is converted into a stop task; when the requirement of the first network state is met, whether the downloading speed of the current network meets the requirement of a preset speed value is further judged, if yes, the pre-downloading task of the start playing segment buffer data of the video to be played is continuously started, and if not, the pause task of the start playing segment buffer data of the video to be played is converted into the stop task. The judgment of the downloading speed of the current network is based on that if the current network speed is too low, even if the pre-downloading task of the start playing segment buffer data of the video to be played is continued, the gap between the playing video segment and the segment buffer data downloading is difficult to complete, and the watching of the playing video is prevented from being influenced.
S03, receiving an instruction for playing the video to be played;
specifically, when receiving an instruction for playing the video to be played, which is triggered by a user, the terminal stops playing the video being played, obtains buffer data of a play start segment of the video to be played locally, and simultaneously switches to a task of playing the video to be played.
S04 plays the start playing segment buffer data.
Specifically, in step S03, after receiving the instruction to play the video to be played, the player of the terminal will go to play the start segment buffer data of the video to be played, and at the same time, will continue to download the buffer data of the rest of the video to be played from the node where the start segment buffer data is downloaded.
Further, with reference to fig. 2, steps S03 and S04, the receiving the instruction to play the video to be played, playing the start playing segment buffer data, includes the steps of:
s05, receiving an instruction for playing the video to be played before the pre-downloading of the start playing segment buffer data of the video to be played is completed;
s06, continuously downloading the start playing segment buffer data of the video to be played;
s07 plays the start-up segment buffer data when the start-up segment buffer data download is completed.
Specifically, in steps S05, S06, and S07 included in steps S03 and S04, when the instruction to play the video to be played is received, the pre-download task of the start-play segment buffer data of the video to be played is not completed, at this time, a part of the start-play segment buffer data of the video to be played may have already been downloaded, but when the instruction to play the video to be played is received, the downloaded part of the start-play segment buffer data is obtained locally, and next to the downloaded node, the buffer data of the other part of the video to be played is continuously downloaded, and when the start-play segment buffer data of the video to be played is completely downloaded, the video to be played is immediately shifted to be played, and simultaneously, the buffer data of the video to be played which has not been downloaded yet is continuously downloaded. In steps S05, S06, and S07, since the start-playing segment buffer data of a part of the video to be played is pre-downloaded, which is equivalent to reducing the time for starting downloading the buffer data of the video to be played after receiving the instruction for playing the video to be played, thereby increasing the start-playing speed of the video and reducing the time required for the user to wait after triggering the playing of the video to be played.
That is, the steps S03, S04 include two schemes, as follows:
(1) and before receiving an instruction for playing the video to be played, finishing pre-downloading the buffer data of the playing starting segment of the video to be played.
(2) When an instruction for playing the video to be played is received, the start playing segment buffer data of the video to be played is not downloaded in advance.
Further, before the step S02 pre-downloading the start segment buffer data with the played video, the method further includes the steps of:
and determining that the current network state supports the pre-download.
Specifically, the network state includes 2G, 3G, 4G, Wifi, etc., and the background will first determine whether the dynamic configuration of the current network state is suitable for supporting the pre-download before executing the pre-download task. For example, when the current state is in a Wifi connection state, since the traffic of the user is not lost, the determination is made as support; when the current network state is 2G, the downloading speed is slow, and the flow of the user is lost, so that the current network state is judged not to be supported.
Further, before the step S02 pre-downloading the start segment buffer data with the played video, the method further includes the steps of:
and taking the video adjacent to the video being played in the current playlist as the video to be played.
The method for taking the video adjacent to the video being played in the current playlist as the video to be played comprises the following steps:
judging the direction of the current playlist which is recently moved by the user;
if the video is moved upwards, taking the video below the video being played in the current play list as the video to be played;
if the video is moved downwards, taking the video above the video being played in the current playing list as the video to be played;
if the video is moved to the left, taking the video on the right side of the currently played video in the current playing list as the video to be played;
and if the video is moved to the right, taking the video on the left of the currently played video in the current playing list as the video to be played.
The video to be played is further determined based on the operation habits of the user. For example, in the recent history operation of the user, assuming that the latest 5 times of operations are taken as an example analysis, and assuming that 4 times of users move to the left, the video on the right of the currently playing video in the current playlist is taken as the video to be played. Wherein, the direction of one moving direction is more than 60% of the directions of the current playlist which is judged to be moved by the user recently, and the direction is judged to be the recent moving direction of the user.
Further, before downloading the start segment buffer data of the video to be played in step S02 in advance, the method further includes the steps of:
acquiring user playing data, and acquiring habits and interests of a user according to the playing data;
and confirming the video to be played from the current playing list according to the habit and the interest of the user.
In this step, the video to be played is determined mainly by combining the habits and interests of the user. The habits and interests of the users are determined according to the types of videos to be watched, for example, the watched historical videos comprise a TV program selection segment of the star A, a short video of the star B interacting with a pet, a short video of the star B receiving the pet and the like, the videos can be screened out, the users like to watch the star B, and the videos which are closest to the sequence of the videos being played and are related to the star B can be screened out in the current play list to serve as the videos to be played.
Further, in step S02, the number of the videos to be played is two or more; the pre-downloading of the start playing segment buffer data of the video to be played comprises the following steps:
judging whether the current network state is a first network state, if so, downloading all start playing segment buffer data of the video to be played in advance; otherwise, pre-downloading the starting playing segment buffer data of a video to be played next to the video being played in the current playing list.
Specifically, in order to more efficiently utilize resources of the download gap, the number of the videos to be played can be more than two, because the pre-downloaded buffer data only for the play start segment of the videos to be played is small in required cache space and low in flow required by downloading, a plurality of videos which are not watched by a user in the current playlist can be selected as the videos to be played, and the play start segment buffer data of the plurality of videos to be played is pre-downloaded, so that the accuracy of determining the videos to be played is improved, the preference of approaching the user is facilitated, and the user experience is improved.
The network states include 2G, 3G, 4G, Wifi, etc., and the first network state is Wifi, that is, when the number of videos to be played is more than two, it is only required that the current network state is the Wifi state to support the pre-downloading of the start-up segment buffer data of all videos to be played; otherwise, only the start segment buffer data of a video to be played next to the video being played in the current playlist is pre-downloaded.
Further, in step S02, before the pre-downloading the start segment buffer data of the video to be played, the method further includes the steps of:
acquiring user playing data, and acquiring habits and interests of a user according to the playing data;
calculating the relative value of the habit and the interest of each playing video and the user in the current playing list;
acquiring a preset number of videos to be played with the maximum correlation value;
the pre-downloading of the start playing segment buffer data of the video to be played comprises the following steps:
judging whether the current network state is a first network state, if so, downloading all start playing segment buffer data of the video to be played in advance; otherwise, judging whether the correlation value of at least one video to be played in the videos to be played is greater than the preset value, if not, pre-downloading the video to be played with the maximum correlation value in the videos to be played, otherwise, pre-downloading the video to be played with the correlation value greater than the preset value in the videos to be played.
In the above embodiment, the relative value of the habit and the interest of the user and the network state are combined, and the video to be played is further determined.

Example four (application example)
Supposing that when a user A uses a certain video player to play a video, a background monitors whether the current segment of buffer data of the video being played is downloaded completely and acquires a current play list corresponding to the video being played, and once the background detects that the current segment of buffer data of the video being played is downloaded completely, the background automatically determines the video to be played in the current play list and starts to pre-download the start-playing segment of buffer data of the video to be played. When the user A finishes watching the playing video or does not want to watch the playing video and triggers sliding to watch the next video, if the next video which is triggered to watch by the user A is matched with the video to be played, the background calls the start playing segment of the buffer data of the video to be played from the middle local to the player for playing, and meanwhile, the buffer data of other parts of the video to be played are continuously downloaded. In this way, when the next video that the user a triggers to watch matches with the video to be played, the player can directly enter the playing of the video to be played without waiting for buffering.
It should be understood that, although the steps in the flowcharts of the figures 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 may be performed in other orders unless explicitly stated herein. Moreover, at least a portion of the steps in the flow chart of the figure may include multiple sub-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 alternately or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
The foregoing is only a partial embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
