Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Video class APP generally optimizes performance when used, such as: and caching more data in advance for the current video, and simultaneously pre-downloading data for one or more videos next to the current video so as to ensure the smoothness of video playing.
But the pre-download for video is typically a fixed duration, such as: the pre-downloaded fixed time length is 5s for the current video and 10s for the next video or videos of the current video.
There is also a scheme in the related art for determining the pre-download duration for the playing time of the current video, for example: if the playing time of the current video is within 0s-5s, pre-downloading data 10s after the current playing time; if the playing time of the current video is within 5s-30s, linearly increasing the pre-downloading time of the current video; if the playing time of the current video is 30s later, pre-downloading data of 50s later than the current playing time; which is also essentially downloading video data of a fixed duration for the current playing time.
Users often stay in unstable environments such as elevators and subways, and when using video APP, the users can play video according to the pre-downloaded data with fixed duration, but if sudden network conditions occur, for example: the network signal suddenly weakens and the like, so that the smooth playing of the video cannot be ensured by the pre-downloaded data with fixed duration, the video loading condition can occur, and the user experience is poor.
Based on the above, the present disclosure provides a video preloading method, a device, an electronic device and a storage medium, which can reduce the video loading rate under the sudden network condition, so as to improve the playing fluency, thereby increasing the user experience.
A video preloading method provided by the present disclosure is first described below.
The video preloading method disclosed by the disclosure can be applied to electronic equipment. The electronic device may be a terminal device, and the terminal device may be a mobile phone, a computer, or the like, which is not limited to a specific form of the electronic device in this disclosure. In addition, the method for preloading can be applied to any scene with video preloading requirements, for example: video scenes played based on video APP, or video scenes played based on other types of APP with video playing function, such as: news APP, shopping APP, etc., to which the present disclosure is not limited.
Specifically, an execution subject of a video preloading method related to the present disclosure may be a video preloading device. The video preloading means may be, for example, functional software running on the terminal device, such as: video class APP; the video preloading device may also be a plug-in an existing client, for example: plug-ins in news class clients, shopping class clients, and the like.
The video preloading method provided by the embodiment of the disclosure may include the following steps:
detecting the motion state of a target user in the running process of a client;
responding to the detection that the motion state is a moving state, if any video data pre-downloading is carried out on the target user currently, adjusting a duration value of a pre-downloading duration utilized by the video data pre-downloading to be a first duration value, and carrying out data pre-downloading on the video by utilizing the first duration value;
the first duration value is a duration value obtained by increasing a target duration value, and the target duration value is a preset duration value based on which the client terminal performs data pre-downloading of each video.
The video preloading method is different from video data preloading with fixed duration in the related art, can detect the motion state of a target user in the running process of a client, responds to the detection that the motion state is a moving state, and adjusts the duration value of the preloading duration utilized by the data preloading of any video to a first duration value to utilize the first duration value to perform data preloading on the video if the data preloading of any video is performed on the target user currently; that is, if the target user is in a moving state during the operation of the client, and any video data is pre-downloaded to the target user, the duration value of the pre-download duration used can be adjusted to be a first duration value, that is, the target duration value of the predetermined duration value based on which the data of each video is pre-downloaded as the client is increased, so as to obtain the first duration value, and the video data is pre-downloaded by using the first duration value. Through the scheme, if the sudden network condition occurs, the data volume of the pre-downloaded data is increased due to the fact that the time length value of the pre-download time length is increased in advance, so that the video loading rate under the sudden network condition can be reduced, the playing fluency is improved, and the user experience is improved.
An exemplary description of a video preloading method provided by the present disclosure is provided below with reference to the accompanying drawings.
As shown in fig. 1, a video preloading method provided by the present disclosure may include the following steps:
s101: detecting the motion state of a target user in the running process of a client;
in the embodiment of the disclosure, the subsequent video preloading can be performed according to the motion state of the target user, and the motion state of the target user in the running process of the client can be detected first. The client may be a video client, or other clients with video playing function, such as a news client, a shopping client, a game client, etc., which is not limited in this disclosure.
Illustratively, the detecting the motion state of the target user during the running process of the client includes:
acquiring the motion frequency of the target user in a preset time period in the operation process of the client; wherein the predetermined time period is a time period determined based on a current time;
and determining the motion state of the target user in the running process of the client based on the motion frequency.
When detecting the motion state of the target user in the running process of the client, the motion frequency of the target user in a preset time period in the running process of the client can be acquired first, and the motion state of the target user in the running process of the client can be determined based on the motion frequency. Wherein the predetermined time period is a time period determined based on the current time, for example: the predetermined time period is the first 5min, 3min, 1min, etc. of the current time, for example: the current time is 1:00, the predetermined time period may be a time period of 12:55-1:00; alternatively, the predetermined time period is the first 5 minutes 1 minute from the current time interval, for example: the current time is 1:00, the predetermined period of time may be a period of time of 12:54-12:59, which is not limited by the present disclosure.
In addition, the method for obtaining the movement frequency of the target user in the preset time period in the operation process of the client may be as follows: and acquiring the movement frequency of the target user in a preset time period in the running process of the client based on a sensor in the electronic equipment to which the client belongs. The sensor in the electronic device to which the client belongs may be: the position sensor, the motion sensor and/or the acceleration sensor and the like can determine the motion frequency of the target user in a preset time period in the operation process of the client based on the data about the motion or the position acquired by the sensor, and the determination mode can be similar to that of the prior art, and is not repeated herein.
The motion state of the target user in the running process of the client can be accurately determined based on the motion frequency in a mode of the motion frequency of the target user in a preset time period in the running process of the client, so that the follow-up response to the detection that the motion state is a moving state is performed, and the data pre-downloading of the video is performed.
Wherein, based on the motion frequency, determining the motion state of the target user in the running process of the client comprises:
if the motion frequency is lower than a first threshold value, determining that the motion state of the target user in the operation process of the client is a static state;
If the motion frequency is higher than a second threshold value, determining that the motion state of the target user in the running process of the client is a moving state;
wherein the second threshold is greater than the first threshold.
In the embodiment of the disclosure, a first threshold value and a second threshold value for the motion frequency are set, the second threshold value is larger than the first threshold value, when the motion state of the target user in the running process of the client is determined based on the motion frequency, if the motion frequency is lower than the first threshold value, the motion state of the target user in the running process of the client can be determined to be a static state; if the motion frequency is higher than the second threshold value, the motion state of the target user in the running process of the client can be determined to be a moving state. Of course, the determined motion state is a motion state for a predetermined period of time, and the motion states determined for different periods of time may be the same or different. In addition, if the motion frequency is higher than the first threshold value and lower than the second threshold value, the video may be preloaded in a manner provided by the related art.
In the embodiment of the disclosure, a first threshold and a second threshold are set, when the motion state of the target user in the running process of the client is determined based on the motion frequency, the motion state of the target user in the running process of the client can be rapidly determined by comparing the motion frequency with the first threshold and the second threshold according to the size relation of the motion state and the second threshold, and then the data pre-downloading of the video can be rapidly performed in response to the fact that the motion state is detected to be the moving state.
It should be emphasized that the specific implementation of detecting a motion state of a target user during a client operation is merely an example, and any specific implementation capable of detecting a motion state of a target user during a client operation may be applied to the present disclosure. In addition, it can be understood that the motion state of the target user in the running process of the client can be detected when the client is in front-end running, namely not in background running; of course, in other implementations, when the client is in front-end operation and the video playing interface is in an open state, the motion state of the target user during the operation of the client may be detected. In addition, the motion state of the target user in the running process of the client can be periodically detected.
S102: responding to the detection that the motion state is a moving state, if any video data pre-downloading is carried out on the target user currently, adjusting a duration value of a pre-downloading duration utilized by the video data pre-downloading to be a first duration value, and carrying out data pre-downloading on the video by utilizing the first duration value;
the first duration value is a duration value obtained by increasing a target duration value, and the target duration value is a preset duration value based on which the client terminal performs data pre-downloading of each video.
When the motion state is the moving state, the video preloading method provided by the invention can respond to the detection that the motion state is the moving state, if any video data is pre-downloaded aiming at the target user at present, longer video can be pre-downloaded, the video loading rate in the burst state is reduced, the play fluency is improved, and the user experience is increased; specifically, the duration value of the pre-download duration utilized by the pre-download of the video data can be adjusted to be the first duration value, so that the pre-download of the video data is performed by using the first duration value, the pre-download duration is longer than the fixed duration at this time, that is, the first duration value is longer than the target duration value, and if the network condition occurs, the pre-download data can be utilized to perform longer-time playing, so that the video loading rate under the sudden condition is reduced, the playing smoothness is improved, and the user experience is increased. The target duration value is a shared fixed duration value of each video.
It can be understood that, before the adjustment, the duration value of the pre-download duration utilized by the data pre-download of the video may be a target duration value; in the present disclosure, a motion state of a target user in a running process of a client may be periodically detected, where the period is a predetermined period of time, and before adjustment, a duration value of a pre-download duration utilized by data pre-download of the video may also be a first duration value adjusted in a previous period, or a second subsequent duration value adjusted in a previous period.
Illustratively, the pre-downloading of data for any video includes: and the data of the video displayed in the playing interface is pre-downloaded, and/or the associated video of the video displayed in the playing interface is pre-downloaded.
For any video, the data can be pre-downloaded for the video at present, and any video can be pre-downloaded by executing the video pre-loading method provided by the disclosure.
The pre-downloading of the data of any video can be the pre-downloading of the data of the video displayed in the playing interface and/or the pre-downloading of the associated video displayed in the playing interface; the playing interface may be a playing interface of a client related to the present disclosure, and the associated video of the video displayed in the playing interface may be the next video or videos of the video displayed in the playing interface, which is not limited in this disclosure.
By pre-downloading the data of the video displayed in the playing interface and/or pre-downloading the associated video of the video displayed in the playing interface, the method can enable: if a network emergency occurs, the user may play the video displayed in the playing interface and/or play the associated video of the video displayed in the playing interface, at this time, video playing may be performed according to the pre-downloaded data, so as to reduce the video loading rate of the video displayed in the playing interface and/or play the associated video of the video displayed in the playing interface, thereby improving the smoothness of playing, further increasing the user experience and having better applicability.
It should be noted that, for any video, the video is a video displayed in the playing interface, and compared with an associated video of the video displayed in the playing interface, because the corresponding target duration value may be different, the value of the first duration value may be different. For example: for the pre-downloading of the video data displayed in the playing interface, the value of the pre-downloading time length based on the pre-downloading of the data can be 5s, namely the target time length value is 5s, and at the moment, the value of the first time length value can be 10s; for each associated video of the video displayed in the playing interface, the value of the pre-download duration is 10s, that is, the target duration value is 10s, and at this time, the first duration value may be 20s.
The above description of the target time period value and the first time period value is merely an example and should not be construed as limiting the present disclosure.

and detecting whether the current network state meets a preset weak network condition, if so, triggering the duration value of the pre-downloading duration utilized for pre-downloading the data of the video to be adjusted to a first duration value, so as to utilize the first duration value to pre-download the data of the video.
Before the time length value of the pre-downloading time length is adjusted to be the first time length value so as to pre-download the data of the video by utilizing the first time length value, whether the current network state meets the preset weak network condition can be detected, and therefore the time length value of the pre-downloading time length is comprehensively adjusted according to the motion state of the target user and the network state. Illustratively, the weak network condition may be that the network speed is lower than a predetermined speed, or that the network signal is lower than a predetermined strength, etc.; the present disclosure is not limited to the specific content of the weak network condition, and any condition content that characterizes the poor network condition may be used as the specific content of the weak network condition.
Specifically, if the current network state meets a predetermined weak network condition, that is, the current network state is poor or general, and the motion state of the target user in the running process of the client is a moving state, the duration value of the pre-download duration utilized by the pre-download of the video data can be adjusted to be a first duration value at this time, so that the pre-download of the video data is performed by using the first duration value, and if an abrupt network condition occurs, the data volume of the pre-download data is increased due to the pre-increase of the duration value of the pre-download duration, so that the video loading rate under the abrupt network condition can be reduced, the play smoothness can be improved, and the user experience is increased.
In addition, if the current network state does not meet the predetermined weak network condition, that is, the current network state is good, and the motion state of the target user in the running process of the client is a moving state, at this time, the duration value of the pre-download duration utilized by the pre-download of the video data can be adjusted to the target duration value, and of course, the duration value can be adjusted to the subsequent second duration value, which is not limited in the disclosure. At this time, if the network state of the user is good, and the data pre-downloading is performed on the video by adopting the first duration value, the pre-downloaded content may not be completely played, and because the network state is good, the real-time downloading of the video data can be performed, compared with the pre-downloading of the data of the first duration value after the fixed target duration is increased, the data of the redundant duration can be downloaded, and the waste of network resources, flow resources, bandwidth resources and the like is caused; therefore, the time length value of the pre-downloading time length utilized by pre-downloading the video data can be adjusted to be the target time length value or the second time length value, the flow utilization rate is improved, the bandwidth cost is reduced, and the network resources are saved.

Through the scheme, if the sudden network condition occurs, the data volume of the pre-downloaded data is increased due to the fact that the time length value of the pre-download time length is increased in advance, so that the video loading rate under the sudden network condition can be reduced, the playing fluency is improved, and the user experience is improved.
In another embodiment of the present disclosure, as shown in fig. 2, the steps further include:
s103: responding to the detection that the motion state is in a static state, if any video data pre-downloading is carried out on the target user currently, adjusting a duration value of a pre-downloading duration utilized by the video data pre-downloading to a second duration value, and carrying out data pre-downloading on the video by utilizing the second duration value;
the second duration value is a duration value obtained by reducing the target duration.
When the motion state is in a static state, the network condition is usually good, and then the video preloading method provided by the invention can respond to the detection that the motion state is in the static state, if any video data is pre-downloaded for a target user at present, shorter video can be pre-downloaded, and the flow utilization rate is improved, so that the bandwidth cost is reduced and the network resource is saved by avoiding the pre-downloading of excessive data; specifically, the duration value of the pre-download duration used for pre-downloading the video data can be adjusted to be a second duration value, so that the pre-download duration of the video data is performed by using the second duration value, and at the moment, the pre-download duration is smaller than the fixed duration, that is, the second duration value is smaller than the target duration value, and at the moment, real-time downloading of the video data can be performed, if the pre-download of the video data is performed according to the target duration value or the first duration value, the pre-downloaded content may not be completely played, so that the pre-download duration of the video data is not excessively long, the pre-download of the video data can be performed by using the second duration value, thereby improving the flow utilization rate, reducing the bandwidth cost and saving the network resources.
It can be understood that, before the adjustment, the duration value of the pre-download duration utilized by the data pre-download of the video may be a target duration value; in the present disclosure, the motion state of the target user in the running process of the client may be periodically detected, and before adjustment, the duration value of the pre-download duration utilized by the pre-download of the data of the video may also be the second duration value adjusted in the previous period, or the first duration value adjusted in the previous period.
Optionally, before the adjusting the duration value of the pre-download duration used for pre-downloading the data of the video to the second duration value to perform data pre-downloading on the video by using the second duration value, the method further includes:
and detecting whether the current network state meets a preset weak network condition, if not, triggering the duration value of the pre-downloading duration used for pre-downloading the data of the video, and adjusting the duration value to a second duration value so as to perform data pre-downloading on the video by using the second duration value.
Before the time length value of the pre-downloading time length is adjusted to be the second time length value, so that the video is pre-downloaded by utilizing the second time length value, whether the current network state meets the preset weak network condition can be detected, and the time length value of the pre-downloading time length is comprehensively adjusted according to the motion state of the target user and the network state. Illustratively, the weak network condition may be that the network speed is lower than a predetermined speed, or that the network signal is lower than a predetermined strength, etc.; the present disclosure is not limited to the specific content of the weak network condition, and any condition content that characterizes the poor network condition may be used as the specific content of the weak network condition.
Specifically, if the current network state does not meet the predetermined weak network condition, that is, the current network state is good, and the motion state of the target user in the running process of the client is a static state, at this time, the network state of the user is good, if the first duration value is adopted to pre-download the video, the pre-downloaded content may not be completely played, and because the network state is good, the real-time downloading of the video data can be performed, and compared with the pre-downloading of the data of the first duration value after the fixed target duration is increased, the redundant duration data can be downloaded, so that the waste of network resources, traffic resources, bandwidth resources and the like is caused; therefore, the time length value of the pre-downloading time length utilized by pre-downloading the video data can be adjusted to be the target time length value or the second time length value, the flow utilization rate is improved, the bandwidth cost is reduced, and the network resources are saved.
In addition, if the current network state meets a predetermined weak network condition, that is, the current network state is poor or general, and the motion state of the target user in the running process of the client is a static state, at this time, the duration value of the pre-download duration utilized by the pre-download of the video data can be adjusted to the target duration value, and of course, the duration value can be adjusted to the first duration value, which is not limited in the disclosure. At this time, the network state of the user is poor or in general, if the second duration value is adopted to pre-download the video, the pre-downloaded content is less, if the network emergency occurs, the pre-downloaded data cannot guarantee smooth playing of the video, and the situation of video loading can occur, so that the user experience is poor. Therefore, the duration value of the pre-download duration utilized by the pre-download of the video data can be adjusted to be the target duration value or the first duration value, so that the pre-download of the video data is performed by using the first duration value, and if the sudden network condition occurs, the data volume of the pre-download data is increased due to the pre-increase of the duration value of the pre-download duration, so that the video loading rate under the sudden network condition can be reduced, the play smoothness is improved, and the user experience is increased.
It should be noted that, for any video, the video is a video displayed in the playing interface, and compared with an associated video of the video displayed in the playing interface, because the corresponding target duration value may be different, the value of the second duration value may be different. For example: for the pre-downloading of the video data displayed in the playing interface, the value of the pre-downloading time length based on the pre-downloading of the data can be 5s, namely the target time length value is 5s, and at the moment, the value of the second time length value can be 0s; for each associated video of the video displayed in the playing interface, the value of the pre-download duration is 10s, that is, the target duration value is 10s, and at this time, the second duration value may be 5s.
The above description of the target time period value and the second time period value is merely an example, and should not be construed as limiting the present disclosure.
The video preloading method provided by the embodiment of the disclosure can also adjust the duration value of the pre-downloading duration utilized by the data pre-downloading of the video to a second duration value in response to the detection that the motion state is the static state, so as to utilize the second duration value to perform the data pre-downloading of the video; at this time, resource waste caused by that the pre-downloaded content may not be completely played can be avoided, the flow utilization rate can be improved, the bandwidth cost can be reduced, and the network resources can be saved. And whether the current network state meets the preset weak network condition can be detected, if not, the duration value of the pre-downloading duration utilized by the pre-downloading of the video data is adjusted to be a second duration value, so that the pre-downloading of the video data is performed by using the second duration value, and if the sudden network condition occurs, the data volume of the pre-downloaded data is increased due to the pre-increased duration value of the pre-downloading duration, so that the video loading rate under the sudden network condition can be reduced, the playing smoothness is improved, and the user experience is improved. It can be seen that, in the embodiment of the present disclosure, the duration value of the pre-download duration utilized by the data pre-download of the video may be comprehensively adjusted according to the static state of the user and the current network state, so as to increase, decrease or keep unchanged the duration value of the pre-download duration utilized by the data pre-download of the video.

If the user is in a mobile state, the size of the pre-downloaded data is increased (for example, the data of 3s before downloading is increased to the data of 10s before downloading from the default), and the size of the buffer level in playing is increased (for example, the data of 20s after downloading is increased to the data of 40s after downloading).
The size of the pre-downloaded data is the size of the pre-downloaded associated video of the video displayed in the playing interface, and the size of the buffer water level in playing is the size of the pre-downloaded data of the video displayed in the playing interface.
