Embodiment 1

[0046] The embodiment of the present invention provides a video quality level matching method, such as figure 1 As shown, the method includes:

[0047] Step S101: Obtain the deframing capability value and download speed of the client.

[0048] For this embodiment, the deframing capability value is a parameter value that reflects the video decoding capability of the client, and the client may have different deframing capability values ​​corresponding to different video quality levels, and since the same client processes low video quality level video The video decoding capability of the video should be higher than the video decoding capability of high video quality level video, so the deframing capability value corresponding to low video quality level is not less than the high video quality level. The download speed is the speed of the client's previous video download under the current network.

[0049] Step S102: Obtain frame rates and bit rates of at least two video quality ...

Embodiment 2

[0059] Another possible implementation of the embodiment of the present invention, on the basis of the first embodiment, further includes the steps shown in the second embodiment, wherein,

[0060] The steps S103 and S104 include:

[0061] From the at least two video quality levels, sequentially acquire the frame rate and bit rate of a video quality level from high to low;

[0062] If the deframing capability value is greater than the frame rate multiplied by the multiple corresponding to the video quality level, and the download speed is greater than the code rate multiplied by the multiple corresponding to the video quality level, take the video quality level as the matching Video quality level.

[0063] For this embodiment, the comparison step in step S103 is performed for each video quality level in order of the levels from high to low. Wherein, corresponding to different video quality grades, different multiples required for comparison are preset. The condition that th...

Embodiment 3

[0065] Another possible implementation of the embodiment of the present invention, on the basis of the first embodiment, further includes the steps shown in the third embodiment, wherein,

[0066] The obtaining the matched video quality grade in the step S104 includes: obtaining a video quality grade with the highest matching grade;

[0067] After obtaining the matched video quality level, the method further includes: acquiring the video of the video quality level, and delivering the video to the client.

[0068] For this embodiment, the comparison step in step S103 is performed for each video quality level one by one in order of the levels from high to low, until the video quality level with the highest matching level is obtained, and the described video quality level is sent to the client. Video quality rating of the video. For example, if the video quality level of the first level does not match the user client through comparison, and the video quality level of the second ...

Abstract

The invention provides a video quality grade matching method which comprises the following steps: obtaining a de-framing capability value and the downloading speed of a client; obtaining frame rate and code rate of at least two video quality grades; comparing the de-framing capability value with the frame rate and the download speed with the code rate; and according to a comparison result, obtaining a matched video quality grade from the at least two video quality grades. According to the video quality grade matching method provided by the invention, a video with the most appropriate video quality grade of the client can be automatically and quickly downloaded for the user, so that the watching experience satisfaction degree of the user is remarkably improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular, the present invention relates to a video quality level matching method, a computer-readable storage medium and a terminal. Background technique [0002] With the rapid development of Internet technology, watching videos through the Internet has become one of the important ways for people to learn and entertain. In order to avoid as much as possible video freezes, unplayable and other phenomena that affect the user's viewing experience, the existing technology usually uses a self-developed audio and video coding algorithm to transcode the original video that the user wants to watch, and obtain a video with a lower bit rate. Videos with less quality loss, so that all playback requests use the video; some video sites will also measure the speed before playback (advertisement period) to remind users to manually select the video gear or automatically downgrade the video after ...
