Example 2
Referring to fig. 2, an embodiment of the present invention provides a video decoding method, where an execution subject of the present invention may be a server, and the method includes:
Step 201: and acquiring terminal information contained in each decoding mode inquiry message received in history.
each user may install a client, which may be a browser or a player, etc., on the terminal that the user uses. When a user plays a new video which is not played by using the client, the terminal reads the terminal information of the user and sends a decoding mode query message containing the terminal information to the server. The server receives and stores the decoding mode query message, then determines a decoding mode according to the terminal information and sends the decoding mode to the terminal. And the terminal determines whether to decode the new video by using a decoding chip of the terminal or a video decoding algorithm stored in the terminal according to the decoding mode.
each decoding method query message stored in the server is each decoding method query message historically received by the server, so the step may be: and acquiring each decoding mode query message stored in the server.
The terminal information of the terminal at least comprises model information and operating system version information of the terminal. The model information of the terminal may be a model of the terminal, and the operating system version information of the terminal may be a version number of an operating system currently installed in the terminal.
Step 202: and counting the number corresponding to each kind of terminal information in the acquired terminal information, selecting the terminal information with the maximum number and preset numerical values, and forming an information set.
Since the terminal sends the decoding mode query message containing the terminal information when the user plays a new video each time, the number corresponding to a certain terminal information is the number of times that the terminal corresponding to the terminal information is used by each user, and thus the terminal corresponding to each terminal information in the information set is the terminal with the maximum frequency of use by the user.
Step 203: and testing the terminal corresponding to each terminal information in the information set through a preset video set to obtain the decoding complexity corresponding to each terminal information in the information set.
The preset video set comprises a plurality of videos with different decoding complexity. And respectively purchasing a terminal corresponding to each terminal information by a technician according to each terminal information in the information set. For each purchased terminal, the terminal uses a hardware decoding mode to decode each video in the video set respectively to obtain successfully decoded videos, selects the maximum decoding complexity from the decoding complexities corresponding to the successfully decoded videos, and determines the selected decoding complexity as the decoding complexity corresponding to the terminal information of the terminal.
the terminal comprises a hardware decoding mode and a software decoding mode, wherein the hardware decoding mode refers to that the terminal decodes a video through a decoding chip which the terminal comprises; the software decoding mode means that the terminal decodes the video through a video decoding algorithm included in the terminal.
There are many decoding chips, about twenty decoding chips exist, each decoding chip supports different decoding complexity, for each terminal, when the terminal is tested through a video set, if the decoding complexity supported by the decoding chip included in the terminal is higher, the video successfully decoded by using the hardware decoding mode of the terminal is more, and if the decoding complexity supported by the decoding chip included in the terminal is lower, the video successfully decoded by using the hardware decoding mode of the terminal is less.
The video in the preset video set is acquired by the server in advance, and the acquisition process may be the following steps (1) to (4), including:
(1): and acquiring the decoding complexity of each video included by the video website, and selecting the video with the largest decoding complexity from each video included by the website.
Specifically, video parameters of each video are acquired from a video website, and the video parameters of the video may include configuration information, resolution, reference frames, length and width of video pictures, frame rate, and the like of the video; and calculating the decoding complexity of each video according to the video parameters of each video, and selecting the video with the maximum decoding complexity from each video included in the website. The video with the greatest decoding complexity may be one or more.
For the operation of acquiring the video parameters of each video from the video website, the operation may be:
And crawling a video file of each video included in the video website from the video website through a web crawler technology, and respectively extracting the video parameter of each video from the video file of each video.
(2): and intercepting a section of video with a video picture meeting the preset picture condition from the selected video.
a duration range can also be preset, and the duration of the intercepted video is located in the duration range.
The preset picture conditions may include that only two characters preferably have dialogs in the same scene, and the mouth shapes of the characters can be clearly seen, the dialogs are Chinese characters, subtitles of the dialogs are required in a film, the speaking rate is approximately the normal speaking rate, a section of the film comprises different scenes, such as indoor scenes, outdoor scenes, landscape scenes, walking scenes and the like, the picture color is rich but cannot be too beautiful, the picture cannot be a certain single color, and the color of the image area in the edge area of the scene has certain stripes.
(3): and converting the intercepted video into a plurality of videos with different decoding complexity, wherein the decoding complexity of each converted video is less than that of the intercepted video.
For example, assuming that the decoding complexity of the video with the largest decoding complexity is selected to be 9, the decoding complexity of the cut video is also 9, and the cut video is converted into a video with a decoding complexity of 8, a video of 7, a video of 6, a video of 5, a video of 4, a video of 3, a video of 2, and a video of 1, respectively.
(4): and forming a video set by the intercepted video and each video obtained by conversion.
for example, the cut video, the converted video with decoding complexity of 8, the video with decoding complexity of 7, the video with decoding complexity of 6, the video with decoding complexity of 5, the video with decoding complexity of 4, the video with decoding complexity of 3, the video with decoding complexity of 2, and the video with decoding complexity of 1 are combined into a video set.
step 204: and selecting the terminal information with the decoding complexity exceeding a preset threshold value from the information set, and forming a white list by the selected terminal information.
Each terminal information in the white list is the terminal information of the terminal capable of decoding the video by adopting a hardware decoding mode.
The decoding complexity of most videos in the video website is within a decoding complexity range, and few videos with the decoding complexity lower than the lower limit value of the decoding complexity range or videos with the decoding complexity higher than the upper limit value of the decoding complexity range. In this step, the preset threshold may be greater than or equal to the upper limit of the decoding complexity range, so that the terminal whose decoding complexity exceeds the preset threshold can successfully decode most of the videos in the video website, and thus the selected terminal information may be grouped into a white list.
For any user, the user may use the client installed on the terminal to play a new video, where the new video is a movie, a tv series, and the like that have not been played by the terminal, and it should be noted that, because the decoding complexity of each episode of the tv series is the same, when a certain episode of the tv series is played for the first time, the terminal needs to query the server for a decoding manner, and when other movies of the tv series other than the episode of the tv series are played, the terminal does not need to query the server for a decoding manner.
Before the terminal uses the client to play the new video, the terminal first obtains its own terminal information, sends a decoding mode query message containing the terminal information to the server to query the server for a decoding mode for decoding the new video, and after receiving the decoding mode query message, the server executes the following step 205.
Step 205: and when receiving a decoding mode query message sent by the terminal, acquiring the decoding mode of the terminal according to the terminal information and the white list of the terminal.
Specifically, when receiving a decoding mode query message sent by a terminal, extracting terminal information of the terminal from the decoding mode query message, and determining whether the terminal information of the terminal exists in a white list, if so, acquiring that the decoding mode of the terminal is a hardware decoding mode, and if not, acquiring that the decoding mode of the terminal is a software decoding mode.
Further, the received decoding method inquiry message is stored.

and the terminal receives the decoding mode sent by the server, if the decoding mode is a hardware decoding mode, the terminal uses a decoding chip included in the terminal to decode the video of the new video, and if the decoding mode is a software decoding mode, the terminal uses a video decoding algorithm included in the terminal to decode the video of the new video.
In the embodiment of the invention, when a decoding mode query message sent by a terminal is received, the decoding mode of the terminal is obtained according to the terminal information and the white list of the terminal, so that the terminal decodes according to the decoding mode, and the video cannot be played due to the decoding failure of the terminal can be avoided; in addition, a white list is constructed according to terminal information contained in each decoding mode inquiry message received historically, so that the constructed white list is the terminal information of the terminal with higher current user use frequency, the terminals corresponding to the terminal information in the white list use a hardware decoding mode to perform video decoding, and the decoding effect of the hardware decoding mode is superior to that of a software decoding mode, so that the current mainstream terminal can be ensured to perform video decoding by using the hardware decoding mode to obtain higher code determining effect.

Referring to fig. 3, an embodiment of the present invention provides a video decoding method, where an execution subject of the present invention may be a server, and the method includes:
step 301: and acquiring terminal information contained in each decoding mode inquiry message received in history.
Each user may install a client, which may be a browser or a player, etc., on the terminal that the user uses. When a user plays a new video which is not played by using the client, the terminal reads the terminal information of the user and sends a decoding mode query message containing the terminal information to the server. The server receives and stores the decoding mode query message, determines a decoding mode according to the terminal information and sends the decoding mode to the terminal. And the terminal determines whether to decode the new video by using a decoding chip of the terminal or a video decoding algorithm stored in the terminal according to the decoding mode.
the decoding mode query messages stored in the server are decoding mode query messages received by the server in history, so that the decoding mode query messages stored in the server can be acquired in the step.
the terminal information of the terminal at least comprises model information and operating system version information of the terminal. The model information of the terminal may be a model of the terminal, and the operating system version information of the terminal may be a version number of an operating system currently installed in the terminal.
Step 302: and counting the number corresponding to each kind of terminal information in the acquired terminal information, selecting the terminal information with the maximum number and preset numerical values, and forming an information set.
Since the terminal sends the decoding mode query message containing the terminal information when the user plays a new video each time, the number corresponding to a certain terminal information is the number of times that the terminal corresponding to the terminal information is used by each user, and thus the terminal corresponding to each terminal information in the information set is the terminal with the maximum frequency of use by the user.
Step 303: and acquiring the decoding chip model of the terminal corresponding to each terminal information in the information set.
specifically, according to model information included in each piece of terminal information in the information set, a decoding chip model of a terminal corresponding to each piece of terminal information is inquired from a preset website.
the preset website comprises information such as model information, operating system version information, decoding chip model and time-to-market information of various terminals which are currently on the market or are about to be on the market. For example, the terminal may be a mobile phone, and many websites currently appear to include model information, operating system version information, decoding chip model, time to market information, and the like of various mobile phones that are currently on the market and are about to come on the market.
Step 304: and removing the terminal information of the terminal with the decoding chip model as the preset model from the information set.
There are many decoding chips, about twenty decoding chips exist, each decoding chip supports different decoding complexity, and for each decoding chip, when decoding a video through the decoding chip, if the decoding complexity supported by the decoding chip is higher, the more the video successfully decoded by the decoding chip, and if the decoding complexity supported by the decoding chip is lower, the less the video successfully decoded by the decoding chip.
the decoding complexity supported by various decoding chips is known at present, and the preset model can be the model of the decoding chip with the decoding complexity smaller than a preset threshold.
step 305: and testing the terminal corresponding to each terminal information in the information set through a preset video set to obtain the decoding complexity corresponding to each terminal information in the information set.
The preset video set comprises a plurality of videos with different decoding complexity. And respectively purchasing a terminal corresponding to each terminal information by a technician according to each terminal information in the information set. For each purchased terminal, the terminal uses a hardware decoding mode to decode each video in the video set respectively to obtain successfully decoded videos, selects the maximum decoding complexity from the decoding complexities corresponding to the successfully decoded videos, and determines the selected decoding complexity as the decoding complexity corresponding to the terminal information of the terminal.
the terminal comprises a hardware decoding mode and a software decoding mode, wherein the hardware decoding mode refers to that the terminal decodes a video through a decoding chip which the terminal comprises; the software decoding mode means that the terminal decodes the video through a video decoding algorithm included in the terminal.
The video in the preset video set is acquired by the server in advance, and the acquisition process may be the following steps (1) to (4), including:
(1): and acquiring the decoding complexity of each video included by the video website, and selecting the video with the largest decoding complexity from each video included by the website.
Specifically, video parameters of each video are acquired from a video website, and the video parameters of the video may include configuration information, resolution, reference frames, length and width of video pictures, frame rate, and the like of the video; and calculating the decoding complexity of each video according to the video parameters of each video, and selecting the video with the maximum decoding complexity from each video included in the website. The video with the greatest decoding complexity may be one or more.
For the operation of acquiring the video parameters of each video from the video website, the operation may be:
and crawling a video file of each video included in the video website from the video website through a web crawler technology, and respectively extracting the video parameter of each video from the video file of each video.
(2): and intercepting a section of video with a video picture meeting the preset picture condition from the selected video.
a duration range can also be preset, and the duration of the intercepted video is located in the duration range.
The preset picture conditions may include that only two characters preferably have dialogs in the same scene, and the mouth shapes of the characters can be clearly seen, the dialogs are Chinese characters, subtitles of the dialogs are required in a film, the speaking rate is approximately the normal speaking rate, a section of the film comprises different scenes, such as indoor scenes, outdoor scenes, landscape scenes, walking scenes and the like, the picture color is rich but cannot be too beautiful, the picture cannot be a certain single color, and the color of the image area in the edge area of the scene has certain stripes.
(3): and converting the intercepted video into a plurality of videos with different decoding complexity, wherein the decoding complexity of each converted video is less than that of the intercepted video.
for example, assuming that the decoding complexity of the video with the largest decoding complexity is selected to be 9, the decoding complexity of the cut video is also 9, and the cut video is converted into a video with a decoding complexity of 8, a video of 7, a video of 6, a video of 5, a video of 4, a video of 3, a video of 2, and a video of 1, respectively.
(4): and forming a video set by the intercepted video and each video obtained by conversion.
For example, the cut video, the converted video with decoding complexity of 8, the video with decoding complexity of 7, the video with decoding complexity of 6, the video with decoding complexity of 5, the video with decoding complexity of 4, the video with decoding complexity of 3, the video with decoding complexity of 2, and the video with decoding complexity of 1 are combined into a video set.
step 306: and selecting the terminal information with the decoding complexity exceeding a preset threshold value from the information set, and forming a white list by the selected terminal information.
Each terminal information in the white list is the terminal information of the terminal capable of decoding the video by adopting a hardware decoding mode.
The decoding complexity of most videos in the video website is within a decoding complexity range, and few videos with the decoding complexity lower than the lower limit value of the decoding complexity range or videos with the decoding complexity higher than the upper limit value of the decoding complexity range. In this step, the preset threshold may be greater than or equal to the upper limit of the decoding complexity range, so that the terminals whose decoding complexity exceeds the preset threshold can successfully decode most of the videos in the video website, and thus the terminal information of the selected terminals may be grouped into a white list.
Since the decoding complexity supported by the decoding chip is less than the preset threshold, and the decoding complexity supported by the terminal including the decoding chip may also be less than the preset threshold, the model of the decoding chip whose decoding complexity is less than the preset threshold is determined as the preset model in step 304, and the terminal information of the terminal whose decoding chip model is the preset model is removed, so that the number of test terminals can be reduced, and the efficiency is improved.
Further, in the embodiment of the present invention, a time period closest to the current time and having a preset time length may also be obtained, the terminal information of the terminal whose time of market emergence information is in the time period and whose decoding chip model is other than the preset model is obtained from the preset website, and the obtained terminal information is added to the white list.
The preset model is a model of a decoding chip with decoding complexity smaller than a preset threshold, so that the decoding complexity supported by the decoding chip in the terminal except the preset model is greater than or equal to the preset threshold, the decoding complexity supported by the terminal except the preset model can also be greater than or equal to the preset threshold, and therefore the terminal information of the terminal except the preset model of the decoding chip can be added into a white list.
For any user, the user may use the client installed on the terminal to play a new video, where the new video is a movie, a tv series, and the like that have not been played by the terminal, and it should be noted that, because the decoding complexity of each episode of the tv series is the same, when a certain episode of the tv series is played for the first time, the terminal needs to query the server for a decoding manner, and when other movies of the tv series other than the episode of the tv series are played, the terminal does not need to query the server for a decoding manner.
Before the terminal uses the client to play the new video, the terminal first obtains its own terminal information, sends a decoding mode query message containing the terminal information to the server to query the server for a decoding mode for decoding the new video, and after receiving the decoding mode query message, the server executes the following step 307.
Step 307: and when receiving a decoding mode query message sent by the terminal, acquiring the decoding mode of the terminal according to the terminal information and the white list of the terminal.
Specifically, when receiving a decoding mode query message sent by a terminal, extracting terminal information of the terminal from the decoding mode query message, and determining whether the terminal information of the terminal exists in a white list, if so, acquiring that the decoding mode of the terminal is a hardware decoding mode, and if not, acquiring that the decoding mode of the terminal is a software decoding mode.
further, the received decoding method inquiry message is stored.
step 308: and sending the decoding mode to a terminal, so that the terminal performs video decoding according to the decoding mode.
and the terminal receives the decoding mode sent by the server, if the decoding mode is a hardware decoding mode, the terminal uses a decoding chip included in the terminal to decode the video of the new video, and if the decoding mode is a software decoding mode, the terminal uses a video decoding algorithm included in the terminal to decode the video of the new video.
