Detailed Description
The present disclosure is described in further detail below with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the disclosure and are not limiting of the disclosure. It should be further noted that, for the convenience of description, only some of the structures relevant to the present disclosure are shown in the drawings, not all of them.
Referring to fig. 1, a flowchart of a video bitrate adjustment method provided in an embodiment of the present disclosure is shown, where the method is applicable to a situation where the data size of a video is effectively reduced on the premise of ensuring the video quality, and the method may be executed by a video bitrate adjustment device, where the device may be implemented in a software and/or hardware manner, and may be configured in a terminal, such as an intelligent device with a camera device. As shown in fig. 1, the method specifically includes:
s110, acquiring data corresponding to the target video during recording, wherein the data comprises terminal data and/or user data.
At present, with the popularization of mobile terminals and the speed increase of networks, the recording of short videos is more and more favored by people, and in order to increase the interestingness of the recorded videos, a user can do various actions (such as dancing) in the video recording process to drive the terminal to perform corresponding motions or add various special effects to the shot videos. However, the motion of the terminal or the special effect added by the user increases the complexity of the recorded video, and the more violent the motion or the more complicated the added special effect is, the larger the recorded video file is, that is, the larger the code rate required for recording the video is.
Based on this, in order to ensure that the recorded video has sufficient definition, when the video starts to be recorded, the terminal device executes a video recording action in response to a user's trigger operation on a video shooting button on a current terminal interface, and records the video according to a preset code rate, where the preset code rate may be, for example, the maximum code rate supported by the terminal system, such as the preset code rate of 12 Mb/s.
Illustratively, the present embodiment records a target video at a code rate of 12Mb/s, and records terminal data and/or user data during the recording of the target video, where the terminal data may illustratively include a motion state parameter of the terminal, and the user data includes data selected by a user during processing of the video, such as special effect data added by the user, a filter added by the user, or a cover selected by the user.
The whole video recording process comprises a video shooting link and a compiling link, so that terminal data can be recorded in the video shooting link, specifically, parameters acquired by at least one sensor arranged on a terminal can be acquired, and terminal data corresponding to a target video during recording can be determined according to the parameters, illustratively, angular velocity information of the terminal acquired by a gyroscope on the terminal equipment is acquired, the motion attitude of the terminal is determined according to the angular velocity information, and the motion speed, the motion intensity and the like of the terminal equipment are determined according to data acquired by acceleration sensing; in the compiling step, user data is recorded, for example, various special effects added by a user are recorded, and detail information of each special effect is obtained correspondingly, such as the complexity of each special effect, wherein the special effects comprise 'burr', 'illusion', 'neon', and the like.
And S120, when the target video is synthesized, adjusting the integrated code rate of the target video according to the terminal data and/or the user data.
In this embodiment, transcoding the video when synthesizing the target video includes performing corresponding processing on the shot video according to the user data, and illustratively, if the user adds at least one special effect in the compiling link, the special effect is superimposed on the video shot in the video shooting link to obtain the target video. Then, the code rate of the target video after the integration is adjusted according to the terminal data and/or the user data, when the specific implementation is realized, the code rate can be adjusted according to the following steps:
and S121, determining a first code rate correction value according to the terminal data, and/or determining a second code rate correction value according to the user data.
When a video is shot, if a user drives a terminal to do various actions, determining a terminal motion type according to the obtained terminal data, and determining a corresponding first code rate correction value according to the terminal motion type. The motion intensity and the complexity corresponding to each motion type are different, so that the first code rate correction values corresponding to different motion types are different. Specifically, the first code rate correction values corresponding to different motion types may be set in advance, or may be learned according to a machine learning method, so as to obtain the optimal code rate correction values corresponding to different motion types.
In the compiling link, if the user processes the shot video, determining a second code rate correction value according to the obtained user data, and exemplarily, if the user adds a special effect to the shot video in the compiling link, determining the second code rate correction value according to the complexity level corresponding to the added special effect. Since each special effect has different complexity, different complexity levels are divided in advance based on the complexity of each special effect and stored in a data packet corresponding to the special effect, and illustratively, the special effect is divided into A, B, C levels which are reduced in sequence. And the second code rate correction values corresponding to the special effects of the same grade are the same. Of course, the optimal code rate correction values corresponding to the complexity levels of different special effects may also be determined according to a machine learning method.
And S122, determining a target code rate correction value according to the first code rate correction value and/or the second code rate correction value.
In this step, if the video is recorded, only the terminal data is obtained, and the user does not process the video, the first code rate correction value is the target code rate correction value; if the terminal does not perform any action during video recording, only the user processes the shot video in the compiling link, and the second code rate correction value determined according to the user data is the target code rate correction value; in addition, when the terminal operates during video recording and the user processes the shot video, the target bitrate correction value is preferably a result of weighted summation of the first bitrate correction value and the second bitrate correction value. Illustratively, if the motion type determined according to the terminal data is a jerk, the corresponding first code rate correction value is 2Mb/s, the special effects added by the user are "burr" and "illusion", and the corresponding second code rate correction values are 2.5Mb/s and 3.5Mb/s, respectively, then the target code rate correction value is 8 Mb/s. Further, in order to ensure the accuracy of the target code rate correction value, the weighting coefficients corresponding to the first code rate correction value and the second code rate correction value may be determined according to an empirical value or other related algorithms. For example, the first rate correction value M corresponds to the weighting factor a, and the second rate correction value N corresponds to the weighting factor b, so that the target rate correction value P is a × M + b × N.
And S123, adjusting the code rate of the synthesized target video according to the target code rate correction value. The target video is recorded at the maximum code rate allowed by the terminal system when the target video is recorded, so that the target video code rate can be adjusted only by subtracting the target code rate correction value from the maximum code rate. Illustratively, the maximum code rate is 12Mb/s, the target code rate is corrected by 8Mb/s, and the adjusted target video code rate is 4 Mb/s.
For the video with the adjusted code rate, the data volume of the video file is reduced, so that the video file can be quickly uploaded to a server, and limit compression and video distribution can be conveniently carried out on the server.
According to the method and the device, the terminal data and the user data in the video recording process are recorded, and the original code rate during video recording is adjusted according to the terminal data and the user data, so that the data volume of the recorded video file is effectively reduced under the condition that the recording definition is ensured, and the transmission of the video file is facilitated.
Referring to fig. 2, a flowchart of a video bitrate adjustment method provided in an embodiment of the present disclosure is shown, where the embodiment is further optimized based on the foregoing embodiment. As shown in fig. 2, the method includes:
s210, acquiring data corresponding to the target video during recording, wherein the data comprises terminal data and/or user data.
And S220, when the target video is synthesized, adjusting the integrated code rate of the target video according to the terminal data and/or the user data.
And S230, if the user name, the terminal model and the terminal data and/or the user data of the target video meet preset specific conditions, compensating the adjusted code rate of the target video according to a set standard corresponding to the specific conditions.
In the embodiment of the disclosure, for some people who have special requirements on the recorded video, such as a netpage or various anchor broadcasters, the people usually use a professional video shooting device when recording the video, and it is undesirable to reduce the definition of the recorded video due to the reduction of the size of the video file by modifying the code rate, so for this special situation, after the adjustment of the code rate of the target video is completed, the code rate of the adjusted target video needs to be compensated.
Illustratively, whether a user is a main broadcasting or a network red is judged according to a user name of a target video, whether a terminal is a professional video shooting device is determined according to a terminal model, and meanwhile, if the terminal data and/or the user data are judged to meet preset specific conditions, the adjusted code rate of the target video is compensated according to a set standard corresponding to the specific conditions. For example, the adjusted target video code rate is 4Mb/s, the compensation value is 3Mb/s, the code rate of the compensated target video is 7Mb/s, the requirement of the network red or the anchor on the definition of the recorded video is met, and meanwhile, the transmission speed of the target video is ensured.
The embodiment of the disclosure is directed to the situation that a video is recorded by professional equipment in a network red or a main broadcast, and if the terminal model, the terminal data and/or the user data meet preset specific conditions, the adjusted code rate of the target video is compensated according to the set standard corresponding to the specific conditions, so that the definition of the recorded video is ensured, and the data volume of the recorded video file is reduced, thereby facilitating the transmission of the video file.
