Watching video is now a necessary entertainment and recreation means for people's daily life, and the transmission and playing of video requires the processes of encoding and decoding. Video decoding is the process of using a specific method to restore digitally encoded video data to the video content it represents or to convert electrical pulse signals to the video information, data, etc. it represents, and only the decoded video can be presented to the user in a player.

The soft decoding is a decoding mode of directly calling CPU resources to perform calculation decoding, and the soft decoding has the advantages that: the cost is low, and secondary investment is hardly needed; the compatibility is good, and decoding of various formats can be supported; the decoded video has good picture quality; the player does not need to be set, and the subtitle and the like are well supported; the disadvantages are that: low decoding efficiency, high power consumption and high heat power consumption.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Example 1
As shown in fig. 1, the method of this embodiment is a flowchart of the optimized video decoding and playing method described in this embodiment, and the method described in this embodiment solves the technical problem that in the prior art, a video decoding mode cannot be automatically selected according to a user's need to implement video decoding, and at the same time, user resources are not wasted. The optimized video decoding playing method in the embodiment includes the following steps:
step 101, setting in a player, and calling a hardware decoder or a software decoder to decode the video according to a decoding request of the video.
In the prior art, video data is transmitted and stored in the form of encoded compressed files, so as to reduce the pressure of the video in the transmission and storage processes. Therefore, when playing video data, the video data needs to be decoded first to render and play. In the prior art, decoding and playing of certain video data can only be performed through a preset hardware decoder or a preset software decoder, and a decoder of a proper type cannot be automatically selected for decoding and playing according to the actual situation of a user. In this embodiment, the decoding request of the video is analyzed, and a corresponding hardware decoder or software decoder is called to perform decoding playing according to the analysis result.
Step 102, a user sends a video playing request, wherein the video playing request comprises the format of the video.
103, the player receives the playing request of the video, analyzes the playing request to obtain the format of the video, and generates a decoding request of the video according to the format of the video; and acquiring the version of a hardware decoder of the equipment where the player is positioned, and comparing the format of the video with the video format supported by the version of the hardware decoder.
Based on the fixed types of the video format and the version of the hardware decoder, the corresponding relation between the version of the hardware decoder and whether each video format is supported or not is created in advance. And when the updated video format or hardware decoder version exists, updating the corresponding relation between the version of the hardware decoder and the support of each video format in time. Therefore, when a hardware decoder is used each time, whether the version of the decoder can support the decoding of the video can be detected in advance through the corresponding relation, and the problem of abnormal decoding process caused by the fact that the decoding of the video in the format is not supported is solved.
And step 104, when the version of the hardware decoder supports the decoding of the video, calling the hardware decoder to decode the video data and playing the video data by the player.
The hardware decoder has the advantages of high decoding efficiency, low power consumption, low heat power consumption and the like, so when the hardware decoder supports the format of the video to be decoded, the hardware decoder is preferentially selected to decode and play the video.
And 105, when the version of the hardware decoder does not support the video decoding of the format, calling the software decoder to decode the video data according to the decoding request of the video and playing the video data.
Although the hardware decoder has the advantages of high decoding efficiency, low power consumption and low heat power consumption, the hardware decoder has poor compatibility, large limitation and complicated arrangement, the software decoder has better compatibility and can support the video decoding of various formats, and the decoded video has better picture quality. Therefore, under the condition that hardware decoding is not supported, the problem that video decoding cannot be continued can be avoided by selecting software decoding, and the use experience of a user is improved.
Step 106, when the version of the hardware decoder supports the decoding of the video, detecting the hardware decoding occupancy rate of the hardware decoder and the software decoding occupancy rate of the software decoder;
and when the difference value between the hardware decoding occupancy rate and the software decoding occupancy rate is greater than or equal to a preset threshold value, calling the software decoder to decode the video data according to the decoding request of the video and playing the video data. Preferably, the predetermined threshold is 30% -60%.
When the video decoding supported by the hardware decoder and the software decoder is carried out, the resource occupancy rates of the hardware decoding and the software decoding are compared based on the consideration most favorable for user equipment, and when the occupancy rates of the hardware decoding and the software decoding are greatly different, the decoding mode with less occupied resources is selected for carrying out the video decoding, so that the method is favorable for saving resources, can improve the video decoding efficiency by utilizing better resources, and reduces the risk of abnormal decoding.
And step 107, acquiring a corresponding display interface from the database according to the version of the hardware decoder and the version of the software decoder, and adjusting and displaying the display interface in the display area according to the selected display interface so as to adapt to the current system and equipment model.
Step 108, setting the priority suitable for being called by a decoder in the player, wherein the first priority is the optimized video decoding mode in the invention; the second priority is a video decoding mode which independently adopts hardware decoding; the third priority is a video decoding mode which solely adopts software decoding.
The optimized video decoding playing method of the embodiment automatically identifies the characteristics of the video to be decoded, performs hardware decoding on the video which must be decoded by using hardware, and performs software decoding on the video which can be realized based on software decoding, thereby solving the problems that the video file with all formats cannot be supported by performing pure hardware decoding on the video and the setting is complicated in the prior art; and the problems of high power consumption and low decoding efficiency in the video decoding process caused by pure soft decoding are solved, so that the user resources are not wasted while the video decoding is realized, and the video decoding efficiency is improved.
Example 2
As shown in fig. 2, which is a schematic flow chart of the method for decoding and playing an optimized video according to this embodiment, this embodiment describes, based on embodiment 1, selecting specific content of a video decoder based on an actual situation of a user. The optimized video decoding playing method in the embodiment includes the following steps:
step 201, setting in a player, and calling a hardware decoder or a software decoder to decode the video according to a decoding request of the video.
Step 202, receiving a playing request of the video, analyzing the playing request to obtain a format of the video, and generating a decoding request of the video according to the format of the video; and acquiring the version of a hardware decoder of the equipment where the player is positioned, and comparing the format of the video with the video format supported by the version of the hardware decoder.
Step 203, when the version of the hardware decoder supports the video decoding of the format, detecting the hardware decoding occupancy rate of the hardware decoder.
Step 204, when the hardware decoding occupancy rate reaches or exceeds a hardware decoding occupancy rate threshold value, calling the software decoder to decode the video data according to the decoding request of the video and playing the video data; and when the hardware decoding occupancy rate is smaller than the hardware decoding occupancy rate threshold value, calling the hardware decoder to decode the video data and play the video data according to the decoding request of the video. Preferably, the hardware decoding occupancy threshold is 10% -70%.
And step 205, when the version of the hardware decoder does not support the video decoding of the format, calling the software decoder to decode the video data according to the decoding request of the video and playing the video data.
Step 206, when the version of the hardware decoder supports the decoding of the video, detecting the hardware decoding occupancy rate of the hardware decoder and the software decoding occupancy rate of the software decoder;
and when the difference value between the hardware decoding occupancy rate and the software decoding occupancy rate is greater than or equal to a preset threshold value, calling the software decoder to decode the video data according to the decoding request of the video and playing the video data.
Step 207, acquiring the version of the software decoder of the device where the player is located, and acquiring the software decoding occupancy rate corresponding to each video format under the version of the software decoder from a database; and comparing the format of the video with the software decoding occupancy rate corresponding to each video format to obtain the software decoding occupancy rate required by the video for software decoding.
Under the condition that the versions of the software decoders are stored in the database, the software decoding occupancy rate corresponding to each video format can be predicted through the software decoding occupancy rate, the software decoding occupancy rate which needs to be occupied when the video is subjected to software decoding can be predicted, the software decoding occupancy rate which is large can be converted into hardware decoding, the software decoding occupancy rate which is in the receiving range of a user can be converted into hardware decoding, and the software decoding occupancy rate can be continuously used for decoding and playing the video.
And 208, detecting the current software decoding occupancy rate of the software decoder, and calling the software decoder to decode the video data and play the video data according to the decoding request of the video when the sum of the software decoding occupancy rate and the required software decoding occupancy rate is less than or equal to the software decoding occupancy rate threshold value of the software decoding. Preferably, the software decoding occupancy threshold of the software decoding is 0-90%.
