Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
The multimedia assets may be picture, video, etc. type assets. In practical applications, for example, when a web page is accessed, a plurality of multimedia resources of the type of thumbnails, dynamic images or videos may be loaded on the web page; the multimedia resources are sequentially loaded in the loading process, for example, the multimedia resources are loaded from top to bottom according to the typesetting positions, or the multimedia resources are loaded according to a preset loading sequence. In the loading process, the network connection speed (hereinafter referred to as network speed) of the electronic device may fluctuate, thereby causing a large difference in loading time of different multimedia resources. The multimedia resource loading method provided by the embodiment of the invention is mainly described below by taking a process of loading a plurality of pictures on a webpage as an example.
As shown in fig. 1, a multimedia resource loading method provided in an embodiment of the present invention is applied to an electronic device, and includes:
step S100, acquiring a first resolution and a first loading time of a loaded first multimedia resource;
step S200, determining a second resolution of a second multimedia resource to be loaded according to the first resolution and the first loading time;
step S300, loading the second multimedia resource with the second resolution.
When a plurality of pictures exist on a webpage accessed by a user, the loading of the pictures has a sequence, when the webpage starts to load a first picture (namely a first multimedia resource), a loading request of the first picture is intercepted, the first resolution of the first picture is determined, timing is started, and when the loading of the first picture on the webpage is finished, first loading time is obtained. According to the first resolution and the first loading time of the first picture, a reasonable expectation can be made on the current network state of the electronic equipment, the second resolution of a second picture to be loaded (namely, a second multimedia resource) is determined according to the current network state of the electronic equipment, and the second picture with the second resolution is loaded when a loading request of the second picture is obtained.
For example, the pictures loaded on the web page have several resolutions, i.e. 2M, 1M, 512k, 256k and 128k, and an acceptable loading time range, e.g. 0.3s to 0.8s, is preset for each resolution. Setting the first resolution of the first picture as 512k, if the first loading time of the first picture is 0.5s, the first loading time is within the acceptable loading time range, which indicates that the current network speed is moderate, and determining the second resolution of the second picture to be loaded as 512 k; if the first loading time is 0.2s and the first loading time is lower than the minimum value of the acceptable loading time range, the current network speed is high, and in order to improve the browsing experience of a user on a webpage, the second resolution of the second picture can be determined to be 1M; if the first loading time is 1s, the first loading time is higher than the maximum value of the acceptable loading time range, which indicates that the current network speed is slow, and in order to avoid situations such as too long loading time, incomplete loading, and the like, the second resolution of the second picture may be determined to be 256 k.
The pictures may be present on the same web page or on different web pages of the same application, for example, when a user closes a web page and opens a new web page, the resolution of the first picture loaded on the new web page may be determined by the resolution and loading time of the last picture loaded on the last closed web page. It will be appreciated that for a dynamic map, the resolution may also be understood as frames per second.
In addition, the multimedia resources can be not only pictures, but also video and other resources; for the video, the resolution ratios of the same video resource in different playing time periods can be adjusted; the resolution may be adjusted for each of a plurality of video resources played in sequence. For example: for a long video, the long video can be pre-divided into a plurality of segments, the playing time of each segment is 2 minutes, and the resolution of the next segment to be loaded is determined by the resolution and the loading time of the previous segment. For another example, for a plurality of short videos with relatively similar time duration, the resolution of the next short video to be loaded may be determined according to the resolution and the loading time of the previously loaded short video.
According to the embodiment of the invention, the resolution of the next multimedia resource to be loaded is determined according to the resolution and the loading time of the loaded multimedia, so that the resolution of the multimedia resource to be loaded can be dynamically adjusted according to the network speed in the multimedia resource loading process; the defect that the loading mode of the multimedia resources in the prior art is not sensitive to the fluctuation of the network connection speed is overcome; the problem of unsmooth loading caused by loading high-resolution multimedia resources in a low network speed environment is effectively solved; and under the high network speed environment, the resolution of the loaded multimedia resources can be improved, and the browsing experience of the user is improved.
Optionally, as shown in fig. 2, the step S200 of determining a second resolution of a second multimedia resource to be loaded according to the first resolution and the first loading time includes:
step S210, determining a first window value according to the first resolution and the first loading time;
step S220, determining a second resolution of the second multimedia resource to be loaded according to the first window value.
In one possible embodiment, for any resolution, the corresponding load time versus window value formula can be expressed as:
wherein, wi(t) represents a window value when the loading time is t at the resolution of the serial number i;
a window value end point value representing a resolution with a sequence number i;
a window value starting value representing a resolution with a sequence number i;
a base load time endpoint value representing a resolution of a sequence number i;
a base load time start value representing a resolution with index i. As described above
All are preset values, and can be defined according to actual needs. The sequence number i of the resolution can be obtained by sequentially ordering and numbering the sizes of the resolutions, for example, for five resolutions of 2M, 1M, 512k, 256k and 128k, the sequence number i thereof can be sequentially defined as 1, 2, 3, 4 and 5.
Let the acceptable loading time range be 0.3 s-0.8 s for each resolution picture, i.e. for any resolution there is
Definition for a resolution of 2K it is,
i.e. according to equation (1), if the obtained w is calculatediWhen the value of (t) is in the interval [1,1.5), the second resolution is determined to be 2K. In defining the window value start point value and the window value end point value at the remaining resolutions, the following relationship may be satisfied:
to ensure the continuity of the window value, a window value w is obtained by calculationi(t) can be calculated from the window value wi(t) finding a unique corresponding resolution.
Based on the above rules, it can further be set that: if calculated according to the formula (1) to obtain wi(t) determining the second resolution to be 1K when the value is in the interval [1.5, 2.5); if calculated wi(t) when the value is in the interval [2.5,5), determining the second resolution as 512 k; if calculated wi(t) when the value is in the interval [5,13), determining the second resolution to be 256 k; if calculated wiThe (t) value is in the interval [13, M), where M is a constant greater than 13, the second resolution is determined to be 128 k.
Assuming that the first resolution of the first picture is 512k, the above formula (1) can be simplified as w3(t) 5t +1, when the first loading time is 0.5s, w is calculated3(t) 3.5, and within the interval [2.5,5), determining the second resolution to be 512 k; when the first loading time is 0.05s, w3(t) ═ 1.25, over the interval [1,1.5), the second resolution was determined to be 2M; when the first loading time is 0.2s, w3(t) ═ 2, in the interval [1.5,2.5), the second resolution is determined to be 1M; when the first loading time is 1s, w3When (t) is 6, the second resolution is determined to be 256k in the interval [5, 13).
Of course, the above description is only for one possible implementation of the present embodiment, and in practical applications,
can be adjusted according to actual needs; for any resolution, the corresponding loading time may not be a linear function (e.g., an exponential function, a quadratic function that increases or decreases within an acceptable loading time, etc.).
In this embodiment, the first window value is determined according to the first resolution and the first loading time, and then the second resolution is determined according to the first window value, so that the second resolution can be directly determined as any resolution according to the network speed, and the resolution of the second multimedia resource can be switched more flexibly.
Optionally, as shown in fig. 3, the step S220 of determining a second resolution of a second multimedia resource to be loaded according to the first window value includes:
step S221, obtaining a second window value, where the second window value is a window value used for determining a first resolution of the first multimedia resource;
step S222, obtaining a third window value according to the first window value and the second window value;
step S223, determining a second resolution of the second multimedia resource to be loaded according to the window value interval where the third window value is located and the corresponding relationship between the preset window value interval and the resolution.
Taking the example of loading multiple pictures on the web page, since the first picture may be the first picture loaded on the web page when the user accesses the web page, or may be the nth picture (N is a positive integer greater than 1) loaded. When the first picture is the first picture, the second window value can be a preset window value; when the first picture is the nth picture, the second window value may be a window value calculated based on the loading process of the N-1 st picture.
To explain the working principle of this embodiment more clearly, the following is combined with the formula (1) and
the following describes a possible implementation of this embodiment:
when a first picture is loaded on a webpage, a preset window value is obtained and set to be 2.5 (corresponding to a second window value at this time), a picture with the resolution of 512k is loaded correspondingly, and the formula (1) can be simplified to w3(t) 5t + 1. If the loading time of the first picture is 1.5s, calculating w3(t) 8.5 (corresponding to the first window value in this case). Averaging the two window values of 2.5 and 8.5 to obtain a third window value of 5.5; the third window value is used to determine the resolution of the second picture to be loaded, and since the third window value is within the interval [5,13), the resolution of the second picture to be loaded is determined to be 256 k.
When the second picture is loaded on the webpage and the third picture is to be loaded, acquiring the sub-group of the second pictureResolution (i.e., 256k) and load time (set to 0.6s), equation (1) now reduces to w4(t) 16t +0.2, and t 0.6s into the formula w4W is calculated in (t) ═ 16t +0.24(t) 9.8 (corresponding to the first window value at this time); since the resolution of the second picture is determined based on the window value of 5.5 (which corresponds to the second window value at this time), the two window values of 9.8 and 5.5 are averaged to obtain a third window value of 7.65; at this time, the third window value is used to determine the resolution of the third picture to be loaded, and since the third window value is still in the interval [5,13), the resolution of the third picture to be loaded is determined to be 256 k.
The determination of the resolution of more loaded pictures can be embodied by the following table:
| load sequence number | 0 (Preset) | 1 | 2 | 3 | 4 |
| Load time | 1.5s | 0.6s | 0.2s | 0.15s | |
| When the corresponding window value is loaded | 8.5 | 9.8 | 3.4 | 2.6 | |
| Next window value (average value) | 2.5 | 5.5 | 7.65 | 5.525 | 4.0625 |
| Next time loading resolution | 512k | 256k | 256k | 256k | 512k |
In the above table, the "current loading corresponding window value" under one loading serial number corresponds to the first window value under the loading serial number; the "next window value" under one loading sequence number corresponds to the third window value under the loading sequence number, and also corresponds to the second window value under the next loading sequence number. The "next loading resolution" at a loading sequence number corresponds to the second resolution at the loading sequence number, and also corresponds to the first resolution at the next loading sequence number.
In this embodiment, when determining the second resolution, not only the first window value calculated according to the first resolution and the first loading time of the first multimedia resource is considered, but also the window value used for determining the first resolution of the first multimedia resource is considered, that is, the resolution of the multimedia resource to be loaded is determined by using the window values of a plurality of time points, so that the resolution of the multimedia resource is prevented from being greatly fluctuated in the loading process.
Of course, in some optional embodiments, in the process of calculating the third window value according to the first window value and the second window value, the third window value may also be calculated by performing weighted average, geometric average, harmonic average, square average, and the like on the first window value and the second window value; alternatively, the third window value is calculated based on more window values.
Optionally, as shown in fig. 4, in step S222, obtaining a third window value according to the first window value and the second window value includes:
step S2221, calculating the change rate of the first window value relative to the second window value;
step S2222, determining a weight coefficient of the first window value according to the change rate;
step S2223, according to the weight coefficient, perform weighted average calculation on the first window value and the second window value to obtain the third window value.
In this embodiment, a third window value is obtained by performing weighted average calculation on the first window value and the second window value, and when the first window value becomes larger or smaller sharply than the second window value, the weight coefficient of the first window value may be decreased.
For example, the weight coefficients of the first window value and the second window value are a and b, respectively, and the variation rate r of the first window value relative to the second window value can be calculated by the following formula:
r ═ second window value/first window value
Define that when r < -0.5 or r >1, the value of a is reduced. Assuming that a-b-0.5 under the initial condition, the second window value is 3 (the resolution of the loaded picture is 512 k); when the first window value is less than 1.5, or more than 6, the value of a can be adjusted to be 0.3; setting the first window value to be 8 specifically, if a is not adjusted, calculating to obtain a third window value of 5.5, and then reducing the resolution of the picture to be loaded to 256 k; if the value of a is reduced to 0.3, the calculated third window value is 4.875, and the resolution of the picture to be loaded is still 512k at this time. Therefore, when the change of the first window value relative to the second window value is too violent, the fluctuation of the multimedia resource resolution ratio in the loading process can be effectively reduced by reducing the weight coefficient of the second window value.
Alternatively, when-0.5 ≦ r ≦ 1, the value of a may be reset back to 0.5.
Optionally, if it is required to quickly adjust the resolution of the multimedia resource to be loaded when the network speed fluctuates severely, the value of a may also be increased when r < -0.5 or r >1, for example, when the electronic device is on a subway and enters an area with a low network speed, the value of a may be increased to quickly switch to loading a picture with a low resolution, so as to complete the loading of the picture on the web page as soon as possible, and avoid the situations of blank loading and incomplete loading after the network speed is too low or no signal area.
The values of a, b, and r are set merely for convenience of explaining the operation principle of the present embodiment, and in practical applications, the values of a, b, and r may be set as needed; in addition, in some possible embodiments, the weighting coefficient b of the second window value may also be adjusted according to r, or a and b may also be adjusted at the same time.
Optionally, in step S210, determining a first window value according to the first resolution and the first loading time includes:
and determining the first window value according to the first resolution and the first loading time and a preset corresponding relation, wherein the preset corresponding relation is the corresponding relation among the resolution of the multimedia resource, the loading time and the window value.
In this embodiment, the preset corresponding relationship may be embodied by a line graph as shown in fig. 5, where the ordinate is a window value, the abscissa is a loading time, and the preset corresponding relationship is divided into a plurality of intervals by different resolutions, each interval having a corresponding loading time variation range (i.e., on the whole abscissa axis, the loading time may not be increased to the right in a single direction along the origin of coordinates).
The preset corresponding relation can be established in the following way:
1) the resolutions of the multimedia resources are sorted according to high and low levels, for example, five resolutions of 2M, 1M, 512k, 256k and 128k are sequentially sorted;
2) defining a reference loading time starting point value for any one resolution ratio
And a base loading time endpoint value
Wherein the subscript i represents the serial number of the resolution, and the serial number i can be sequentially defined as 1, 2, 3, 4 and 5 for five resolutions of 2M, 1M, 512k, 256k and 128 k; for the
Corresponding to different values of i
Can be the same or different from each other,
the same is true for the same;
3) a base load time origin value corresponding to any one of the resolutions
Base load time end value
Defining window value start points respectively
Window value end point value
Wherein the content of the first and second substances,
4) will be provided with
The resolution, the loading time and the window value of the multimedia resource are sequentially connected by a straight line, and the corresponding relationship among the resolution, the loading time and the window value of the multimedia resource is established, that is, for any resolution, the relationship between the corresponding window value and the loading time is a linear function relationship (the relationship corresponding to the resolution of 128k is not shown in fig. 5)
Value and function line).
When a first window value is determined, firstly determining a calculation interval according to a first resolution, namely determining a linear function relation between the window value and loading time, and then calculating to obtain the first window value according to the first loading time and the determined linear function relation; in a subsequent step, the second resolution is determined using the first window value, e.g. when the first window value is at
When in range, the second resolution is determined to be 512 k.
In the practical application of the method, the material is,
the two can also be connected by a curve, such as an exponential function curve, a one-way increasing quadratic function curve, and the like.
The embodiment determines the first window value through the first resolution, the first loading time and the preset corresponding relation, and has the advantages of accuracy and quickness.
Optionally, the resolution in the preset corresponding relationship is in positive correlation or negative correlation with a window value change rate, where the window value change rate is a change rate of a window value relative to a loading time in the preset corresponding relationship.
As shown in fig. 5, in one possible embodiment, the slope of the line corresponding to the resolution on the left side is smaller than the slope of the line corresponding to the resolution on the right side, that is, the resolution is inversely related to the window value change rate. The larger the resolution ratio is, the smaller the window value change rate is, and the smaller the resolution ratio is, the larger the window value change rate is, so that when a low-resolution picture is loaded, the window value can move to a high resolution ratio more easily, can be switched to the high-resolution picture more quickly, and can be kept in a high-resolution picture area more stably.
In another possible embodiment, the slope of the line corresponding to the left resolution is greater than the slope of the line corresponding to the right resolution, that is, the resolution is positively correlated to the window value change rate. When the resolution ratio is larger, the window value change rate is larger, and when the resolution ratio is smaller, the window value change rate is smaller, so that the image can be more stably kept in a low-resolution image area.
According to the multimedia resource loading method provided by the embodiment of the invention, the loading time and the resolution of the loaded multimedia resource are used as input, and the resolution of the multimedia resource to be loaded after dynamic adjustment is carried out, so that the multimedia resource can still be displayed on a webpage or application quickly under the condition that the network environment of the electronic equipment fluctuates, and a user can obtain better browsing experience.
