The application relates to an Internet video playing method, which is used for improving the defects of the existing fixed definition code stream, matching the best definition code stream level according to the condition of playing equipment and further improving the user experience.
Specifically, the application discloses a sharpness adjustment method, referring to fig. 1, the method may include:
step S101: and acquiring equipment parameters of the playing equipment, network speed information of a network environment where the playing equipment is located and video fluency data of the playing equipment.

A mapping table may be pre-established, where a mapping relation between device parameters, network speed information, and video smoothness data and definition levels under each definition is stored, and when the device parameters, network speed information, and video smoothness data are determined, an optimal definition level corresponding to each definition may be determined according to the mapping table. High definition-level 1, high definition-level 2, high definition-level 3; the individual sharpness levels under blue light sharpness include: the level configuration mode of blue light-level 1, blue light-level 2 and blue light-level 3 can be used for transcoding by using a more efficient compression algorithm according to an equipment user experience model under the condition that the image quality experience of playing equipment is not reduced, and provides high-quality and smooth playing video for users.
Step S103: and acquiring a video playing request uploaded by the playing equipment.
When playing video, the server side is used for completing the deployment of detail service, string taking service, media resource service, recommendation service and CDN dispatcher service and providing online service;
when a user needs to play a certain video file, the playing device is plugged with a power supply and started up, the Internet video application is started, certain video content is selected in the playing device, a video content detail page is entered, a video detail interface of detail service is requested, the detail service receives a request of the playing device, the detail service requests media resource service to acquire video details and a definition list, and the recommendation service requests to acquire definition levels recommended by a current terminal, wherein the current terminal refers to the playing device, the recommended definition levels are the optimal definition levels under the definition corresponding to the playing device, and specifically, in actual application, the recommendation service can be matched with the type, support resolution, network speed information, video fluency data and the like according to the uplink device parameters of the playing device of the terminal device, and is matched with the level corresponding to the optimal definition of the current terminal device to be recorded as the optimal definition level; the detail service assembles a complete video detail data return terminal according to the return results of the media resource service and the recommendation service; and the playing equipment receives the returned result of the detail service and displays the video details. Meanwhile, obtaining a video play string according to a certain definition and definition level request string service returned by the detail service; the string taking service receives a string taking request of the playing device, and requests the media resource service to obtain all definition code stream file lists of the current string taking video; and judging whether the classification intelligent definition is contained or not by the string taking service according to the code stream file list returned by the media resource service, namely, whether the classification intelligent definition is contained or not under each definition, and when the classification intelligent definition is contained, detecting that the uplink parameters of the playing equipment contain video playing requests, and continuously executing the step S104.
Step S104: and acquiring the definition in the video playing request.
When a video playing request uploaded by the playing equipment is obtained, extracting definition in the video playing request, wherein the definition can be standard definition, high definition and blue light definition.
Step S105: and determining a play address based on the definition and the best definition level corresponding to the definition.
In this step, referring to fig. 2, when video needs to be played based on the definition and the best definition level corresponding to the definition, the string service request recommendation service obtains the best definition level corresponding to the definition in the play request of the current terminal. Screening the playing file (code stream file) according to the definition and the best definition level; requesting the CDN dispatcher to acquire a CDN play address according to the play file; the CDN dispatcher returns the CDN playing address of the video code stream file to the string fetching service, and the string fetching service returns the CDN playing address of the video code stream file to the playing device; and after receiving the play address returned by the string taking service, the playing device starts playing the video.
After determining the definition in the video playing request, determining the corresponding optimal definition level under the video definition according to the analysis result of step 102, and when the definition and the optimal definition level are determined, determining the playing address of the video file to be played.
According to the technical scheme disclosed by the embodiment of the application, when the user equipment plays the video file, firstly, the optimal definition level under each definition is determined based on the equipment parameters, the network speed information of the network environment where the playing equipment is located and the video fluency data of the playing equipment, after the video playing request uploaded by the playing equipment is acquired, the definition in the video playing request is acquired, the playing address is determined based on the definition and the optimal definition level corresponding to the definition, the video code stream file is called based on the video playing address, and then video playing is carried out, so that the optimal video file under the current definition is provided for the playing equipment, and the situation of playing blocking of the playing equipment when playing the video is reduced.
The working condition of the playing device and the network environment where the playing device is located are not unchanged, if the playing device has multiple applications and the network speed information is reduced, the data processing speed of the playing device is too slow, or the acquisition speed of the video file is too slow, if the playing device continues to play the video file at the current best definition level, the situation that the played video file is blocked occurs is shown, for this case, in this scheme, after determining the playing address based on the definition and the best definition level corresponding to the definition, the method further includes:
step S201: controlling the playing equipment to play the video based on the playing address;
step S202: and acquiring video fluency data at the current moment.

Step S203: judging whether the optimal definition level needs to be adjusted or not based on video fluency data at the current moment;
after the video fluency data corresponding to the current moment is obtained, whether the optimal definition level needs to be adjusted or not can be judged based on a preset judgment strategy.
For example, a preset smoothness is preset, when the video smoothness data is greater than the smoothness, it indicates that the playing video is free of jamming, otherwise, it indicates that the playing video is jammed, and the best definition level needs to be reduced, and at this time, the video smoothness data of the playing device needs to be based on the device parameters of the playing device, the network speed information of the network environment where the playing device is located, and the video smoothness data of the playing device.
Step S204: when the optimal definition level needs to be adjusted, determining the optimal definition level under the current definition based on the equipment parameters, the network speed information at the current moment and the video fluency data, and marking the optimal definition level as an optimal definition correction level;
step S205: and re-determining the playing address based on the definition and the optimal definition correction level.
In the technical solution disclosed in this embodiment, when the current network speed is higher than the corresponding network speed when determining the optimal definition level, it indicates that the playing device may rapidly implement downloading of the playing video, and at this time, the definition level may be further improved on the basis of the optimal definition, and at this time, when the previous moment video fluency data is not less than the preset fluency, the method may further include: judging whether the difference between the current network speed information and the first network speed information is larger than a preset value or not; the first network speed information is network speed information corresponding to the optimal definition level, and the preset value is a value calibrated in advance and used for representing the difference value between the two network speeds. And when the difference between the current moment network speed information and the first network speed information is larger than a preset value, judging that the optimal definition level needs to be adjusted.
In this scheme, when the difference between the current time and the first network speed information is greater than a preset value, the situation may occur that the current network speed information is greater than the first network speed information, or the current network speed information is smaller than the first network speed information, when the current network speed information is greater than the first network speed information, it is indicated that a user can watch a video picture with higher quality, at this time, it is determined that the best definition level needs to be adjusted, when the current network speed information is less than the first network speed information, at this time, since the video smoothness data is not less than the preset smoothness, it is indicated that the video can be smoothly played, at this time, the played data may be the video data cached by the playing device, if the cached data is played, a clip may appear on, at this time, it may be determined that the best definition level needs to be adjusted, and of course, it may also be determined that the best definition level needs not to be adjusted, and when the video smoothness data such as the video smoothness level is less than the preset smoothness level is displayed.
After determining the optimal definition correction level, taking the optimal definition correction level as the optimal definition level, repeatedly executing the flow, and thus, realizing the self-adaptive adjustment of the definition level of the played video.
In this embodiment, after determining the play address based on the definition and the best definition modification level, the end time corresponding to the video data buffered by the play device may be taken as the start time, where the end time is the time corresponding to the last video frame corresponding to the buffered video data, and based on the video time corresponding to the frame, the video data is continuously acquired by the play address corresponding to the best definition modification level, so as to ensure continuity of playing video.
In the technical solution disclosed in this embodiment, the video playing request may include, in addition to the definition, a definition level selected by the user under the definition, and when the definition level is not empty, the playing address is determined directly based on the definition and the definition level, and at this time, the playing address does not need to be determined based on the optimal definition level, and when the definition level in the video playing request is empty, the playing address may be determined based on the definition and the optimal definition level corresponding to the definition;
in the technical solution disclosed in this embodiment, if video playing is desired based on different definition levels, before this, a code stream file corresponding to the definition level needs to be created, in this solution, a definition level service may be configured only for some specific videos, and those videos with no definition level are not distinguished, so that the services described in the foregoing embodiments of the present application cannot be enjoyed, and therefore, in the foregoing solution, after obtaining a video playing request uploaded by a playing device, before determining a playing address based on the definition and an optimal definition level corresponding to the definition, the method may further include: acquiring a code stream file list of a video to be played, and judging whether a definition level corresponding to the definition exists in the code stream file list; when the definition level corresponding to the definition does not exist, indicating that the video is not subjected to further definition level division on the basis of the definition, and determining a play address based on the definition and the optimal definition level corresponding to the definition, wherein the method comprises the following steps: and determining a play address based on the definition. That is, referring to fig. 2, the scheme can be summarized as: requesting a string service to acquire a video playing address, then acquiring a video code stream file list corresponding to the video playing address, and judging whether the string service contains classified intelligent definition according to the code stream file list returned by the media resource service, wherein the classified intelligent definition is the definition level under each definition in the application, and if the classified intelligent definition is contained: and when the play request does not carry the definition level parameter (the definition level is null), in order to be compatible with the definition level not transmitted by the old version, the string-taking service request recommending service acquires the recommended definition level (the best definition level above) corresponding to the definition of the current terminal request string. Screening the corresponding playing files according to the definition and the best definition level; if the classification intelligent definition is not contained: and screening the corresponding playing files according to the definition. And if the definition level parameter is carried in the playing request (the definition level is not null), screening the playing file directly based on the definition and the carried definition level.
