The following embodiments will be described in detail, respectively, and it should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1b, fig. 1b is a schematic flow chart of a video playing method provided in the present application. The specific flow of the video playing method can be as follows:
101. and acquiring a target video.
For example, specifically, the target video may be obtained according to a video playing operation, where the video playing operation may be triggered by a user for the playing device, or may be triggered by the playing device itself, for example, a playing control is displayed in a display screen of the playing device, and the user may trigger the video playing operation by clicking the playing control; for another example, the playing device may trigger a video playing operation according to a preset policy, specifically, the playing device plays a certain video within a preset time period, that is, the playing device triggers the video playing operation within the preset time period.
Video (Video) generally refers to various technologies for capturing, recording, processing, storing, transmitting, and reproducing a series of still images as electrical signals. When the continuous image changes more than 24 frames (frames) of pictures per second, human eyes cannot distinguish a single static picture according to the persistence of vision principle; it appears as a smooth continuous visual effect, so that the continuous picture is called a video. In the application, a video corresponding to the video playing operation is determined as a target video.
102. And reporting the video identifier of the target video to a server, and receiving a play mode corresponding to the target video returned by the server according to the video identifier.
The video identifier is used to determine information of the video composition, and includes a name of the target video (such as a name of a tv show, a name of a movie, or a name of a variety program, etc.), a number of the target video in a server of the video client, and a serial number of the target video in a video list, etc.
For example, the video platform may add an identifier to its own video so as to determine a corresponding video according to the video identifier subsequently, and specifically, may add, in the video attribute information, product identifier information to which the video belongs, video identifier information of a specific video to which the video belongs, location information of the video in a video list to which the video belongs, and information such as video type information of the video, and the like
According to the method and the device, the video identification of the target video is reported to the server, the server can reduce local overhead according to the play mode corresponding to the target video returned by the video identification, and the server can obtain the play mode recommended by the target video through data statistical analysis, wherein the play mode can comprise image parameters, sound effect parameters, language parameters and the like of the target video during playing.
Optionally, in some embodiments, the server may determine, through data statistical analysis, that the user selects the most playback modes when viewing the target video, so as to obtain a playback mode recommended by the target video; for another example, the server may determine, through data statistical analysis, a selection number corresponding to each play mode in which the target video is viewed, then obtain, by the server, a user portrait corresponding to a user viewing the target video, and determine, based on the selection number and the user portrait, a play mode corresponding to the target video, that is, optionally, in some embodiments, the step "reporting the video identifier of the target video to the server, and receiving, by the server, the play mode corresponding to the target video returned according to the video identifier" may specifically include:
(11) determining target user account information corresponding to a target video;
(12) constructing a user portrait of the target user account information according to the historical browsing data of the target user account information;
(13) and reporting the user portrait and the video identifier of the target video to a server, and receiving video image parameters and video sound effect parameters corresponding to the target video returned by the server according to the user portrait and the video identifier.
The target user account information is user account information of a currently logged-in video application, the historical browsing data includes videos browsed by the user account in a historical time period (hereinafter referred to as historical browsing videos), the historical browsing videos include watched videos and marked videos, the watched videos are videos marked by videos watched by the user in the historical time period and marked by the user in the historical time period, and the marked videos can be videos collected by the user and the like.
Specifically, a user portrait of the target user account information may be constructed according to the watched video and the marked video of the user, where the user portrait is a tagged user model abstracted according to information such as user attributes, user preferences, living habits, and user behaviors. Colloquially, a user is labeled, and the label is a highly refined characteristic mark obtained by analyzing user information. By tagging, a user may be described with some highly generalized, easily understandable features that may make it easier for a person to understand the user and may facilitate computer processing. The user representation may include: and then reporting the user portrait and the video identifier of the target video to a server, and receiving the video image parameter and the video sound parameter corresponding to the target video returned by the server according to the user portrait and the video identifier.
Optionally, in some embodiments, historical browsing data of the target user account information may be acquired, then a historical browsing video meeting a preset condition is selected from the historical browsing data, and a user portrait of the target user account information is constructed according to the selected historical browsing video. For example, it can be set as: the videos browsed in the last 7 days can also be set as: the video carries the label of the action word eye, and the preset condition can be set according to specific conditions, which is not described herein again.
103. And performing content identification on the target video to obtain a content identification result of the target video.
In the identification process, the target video may be segmented to obtain a plurality of video segments, so as to identify the content of the target video based on the video segments. The video segment may segment the target video according to the video playing time, for example, segment the target video by the video playing time of 5s to obtain a plurality of video segments with the video playing time of 5 s. The video segment may also segment the video to be identified according to the video frame number, for example, segment the target video by 240 frames of video images to obtain a plurality of video segments including 240 frames of video images. In practical applications, the manner of video segmentation and the granularity of video segmentation (the playing duration of a video segment or the number of frames of video images included in a video segment) may be set according to practical application scenes, and are not limited herein.
The video segmentation is performed on the target video content, which is equivalent to that the target video content is finely divided, so that the content granularity of the identification basis is smaller, and a data basis is provided for the subsequent identification of the target video content based on the video segments. Next, a convolutional neural network may be used to perform content recognition on each video segment, so as to obtain a content recognition result of the target video, and then step 104 is performed.
104. And playing the target video based on the content identification result and the playing mode.
The playing mode indicates corresponding video image parameters and video sound effect parameters when the target video is played, the video image parameters may include image resolution, image size, and image color, and the image resolution refers to the number of pixels (in units of "pixel/inch" or "pixel/centimeter") included in a unit length of the image in the width and height directions. For the same image, the higher the resolution is, the more detailed the description of the image is, and the larger the required data amount is; the lower the resolution, the coarser the image, and the smaller the data volume; the image size is the total number of pixels included in the entire image and is expressed by the product of the width-direction pixels and the height-direction pixels. The size of the multimedia image material does not exceed the size of the work presentation window generally; the image color is how many colors are included in the image, and is related to the number of bits (bits) used to describe the color. The former is called color depth and the latter is called bit depth. The relationship between them is color depth-2 bit depth. The lower the bit depth of the image, the smaller the data amount, and the lower the display quality; the higher the bit depth, the larger the data amount, and the higher the display quality. Sound effects are effects produced by sound, i.e. noise or sound added to the soundtrack to enhance the realism, atmosphere or dramatic message of a scene. The sound includes musical tones and sound effects. In this application, the video audio refers to the ambient audio, and the ambient audio mainly refers to handles sound through digital audio processor, makes sound and has different spatial characteristics, for example hall, opera house, cinema, karst cave, stadium etc.. The ambient sound effect is mainly realized by processing the sound through ambient filtering, ambient displacement, ambient reflection, ambient transition and the like, so that a listener feels like being in different environments.
It can be understood that, the video image parameters and the video sound effect parameters corresponding to the target video in the play mode may be determined, and then, based on the content recognition result, the video image parameters, and the video sound effect parameters, the target video is played, that is, optionally, in some embodiments, the step "playing the target video based on the content recognition result and the play mode" may specifically include:
(21) determining video image parameters and video sound effect parameters corresponding to a target video in a play mode;
(22) and playing the target video based on the content identification result, the video image parameters and the video sound effect parameters.
After the video image parameters and the video sound effect parameters are determined, the video image parameters and the video sound effect parameters can be adjusted according to the content identification result, for example, the image color of the target video and the size of playing sound are adjusted, so that the adjusted image color and sound effect are more consistent with the target video.
However, it should be noted that, because the image colors are various, even for the same target video, the corresponding image colors are different under different policies, in order to reduce the amount of calculation, the video sound effect parameter may be adjusted based on the content recognition result, and the target video is played according to the video image parameter and the adjusted sound effect, that is, optionally, in some embodiments, the step "playing the target video based on the content recognition result, the video image parameter, and the video sound effect parameter" may specifically include:
(31) adjusting the video audio effect parameters based on the content identification result to obtain an adjusted audio effect;
(32) and playing the target video according to the video image parameters and the adjusted sound effect.
It should be further noted that, during video playing, a situation that a video is stuck during video playing due to network jitter may occur, so that the network transmission speed may be detected, and when the network transmission speed is detected to be smaller than a preset value, the video image parameter may be reduced, so as to reduce the transmission amount of data, and further solve the problem that the video is stuck during video playing due to network jitter, that is, optionally, in some embodiments, the step "playing the target video according to the video image parameter and the adjusted sound effect" may specifically include:
(41) detecting the current network transmission speed;
(42) when the network transmission speed is detected to be smaller than a preset value, reducing video image parameters;
(43) and playing the video image corresponding to the target video by reducing the parameters of the rear video image, and playing the audio corresponding to the target video by adjusting the rear sound effect.
For example, the preset value is 100kb/s, when it is detected that the network transmission speed is less than 100kb/s, the image resolution in the video image parameter is reduced to 300PPI, and finally, the video image corresponding to the target video is played by the reduced video image parameter, and the audio corresponding to the target video is played by the adjusted audio effect, wherein the preset value can be set according to the actual situation, and is not described herein again.
In addition, in the present application, there are two types of adjustment of video sound effect parameters based on the content recognition result:
1) adjusting the video sound effect of the whole target video based on the content identification result, that is, optionally, in some embodiments, the step "adjusting the video sound effect parameter based on the content identification result to obtain the adjusted sound effect" may specifically include:
(51) determining the video type of the target video according to the content identification result;
(52) and adjusting the video audio effect parameters based on the video type to obtain the adjusted sound effect.
For example, specifically, the target video is determined to be a suspicion type video based on the content recognition result, then, the video audio effect parameter may be adjusted so that the adjusted sound effect better conforms to the suspicion type target video, and finally, the target video is played according to the video image parameter and the adjusted sound effect.
2) Based on the content recognition result, the target video is segmented, and the video audio effect parameter is adjusted according to the video content of the video clip, that is, optionally, in some embodiments, the step "adjusting the video audio effect parameter based on the content recognition result to obtain the adjusted sound effect" may specifically include:
(61) segmenting the target video based on the content identification result to obtain a video segment corresponding to the target video;
(62) and detecting the video content of the video clip, and adjusting the video sound effect parameters based on the detected video content to obtain the adjusted sound effect.
For example, the target video is segmented based on the content recognition result to obtain a video clip a, a video clip B and a video clip C, wherein the content type of the video clip a and the content type of the video clip B are both of a type of puzzling, and the content type of the video clip C is of a type of thrilling, so that the video sound effect parameters of the video clip a and the video clip B can be adjusted to the video sound effect parameters corresponding to the type of puzzling, and the video sound effect parameters of the video clip C are adjusted to the video sound effect parameters corresponding to the type of thrilling.
It should be further noted that, for a target video with multiple languages, the language corresponding to the target video when the target video is played may be determined according to the user image of the user, for example, the language corresponding to the target video when the target video is played is determined to be chinese according to the user image of the user, and when the language information of the target video indicates that the language of the target video does not contain chinese, the language corresponding to the target video when the target video is played is determined to be english; for another example, when the language information of the target video indicates that the language of the target video does not contain the chinese language, prompt information is generated, and a language selection control is displayed, so that the user can select the corresponding language according to actual requirements.
In addition, when the target video is played or after the target video is played, the target video may be switched, that is, optionally, in some embodiments, after the step "playing the target video based on the content identification result and the play mode", the method may specifically include:
(71) when video switching operation triggered by a target video is detected, determining a switching video corresponding to the video switching operation;
(72) and acquiring video playing parameters corresponding to the target video, and switching and playing the target video into a switching video based on the playing parameters.
The video switching operation may be triggered by a user or by a system, for example, when the user watches a target video, the video switching operation is triggered by a remote controller or a touch display screen; or, after the target video is played, the system automatically switches to the next video, so as to trigger the video switching operation, and please refer to the foregoing embodiment for the way of switching the target video to the switched video based on the playing parameters, which is not described herein again.
After the target video is played, the playing record of the played target video can be reported to the server, so that the most image and sound effect modes selected by the movie user can be counted by using big data analysis, and the image and sound effect mode recommended by the target video can be obtained.
Therefore, after the target video is obtained, the video identifier of the target video is reported to the server, the play mode corresponding to the target video returned by the server according to the video identifier is received, then, the content of the target video is identified, the content identification result of the target video is obtained, and finally, the target video is played based on the content identification result and the play mode.
