Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
In order to solve the problems that in the prior art, if a certain frame of image has more characters displayed and a user cannot acquire all the displayed characters during the playing of the frame of image, the playing progress needs to be adjusted manually, and the operation is complicated and time-consuming, the invention provides a playing progress adjusting method.
For convenience of description, the following description will be made of an embodiment of the method taking as an example that an execution subject of the method is a terminal device capable of executing the method. It is understood that the implementation of the method by the terminal device is only an exemplary illustration, and should not be construed as a limitation of the method.
Specifically, the method for adjusting the playing progress provided by the invention comprises the following steps: firstly, acquiring the playing duration of a target image frame including target text content in a video to be played; then, determining the complexity of the target character content based on the playing time of the target image frame and the number of characters in the target character content; and finally, adjusting the playing time of the target image frame and the playing time of the target text content based on the complexity of the target text content and a preset complexity threshold, wherein the preset complexity threshold is determined based on the text reading number of a preset number of users in a preset time period.
In the embodiment of the invention, the playing time of the target image frame including the target text content in the video to be played can be obtained, the complexity of the target text content is determined based on the playing time of the target image frame and the number of the characters in the target text content, and finally the playing time of the target image frame and the target text content is adjusted based on the complexity of the target text content and a preset complexity threshold. Therefore, when the text contents corresponding to certain image frames in the video watched by the user are excessive, the playing time of the image frames and the corresponding target text contents can be automatically adjusted according to the complexity of the text contents and the preset complexity threshold value, the user can be ensured to clearly see and acquire the text contents in the image frames, and convenient experience is provided for the user to efficiently acquire the text contents in the video.
The following describes in detail an implementation process of the method with reference to a schematic flow chart of a specific implementation of the method for adjusting a play progress shown in fig. 1, including:
it should be understood that the target text content is text content displayed in the video to be played, and includes text of subtitles, text of object introduction, and the like displayed on the image frame in the video to be played.
In the video playing process, the characters displayed in the video are only a way for assisting the user to understand the content of the video, and besides the characters displayed in the video, in the video playing process, the user can understand the content of the video through the image frames displayed in the video and the sound in the video. This makes it easier for some videos with simpler content to receive and understand what the video is intended to convey when the user watches such videos.
For some videos with complex contents, for example, videos that include descriptions of many characters in the early stage of video playing, it is difficult for users to receive all contents transmitted in the videos while watching the videos, and some characters may be missed, or the users may not pay attention to the conversation between the characters while watching the descriptions of tasks. If a user wants to acquire all characters displayed in a certain image frame in the video playing process, the user needs to manually adjust a playing progress bar of the video to find character information missed by the user.
Obviously, this will bring a very tedious user experience to the user, and in order to solve this problem, the embodiment of the present invention may determine the playing time length of the target image frame corresponding to the target text content in the video to be played, determine the playing speed of the target text content based on the playing time length, and then reduce the playing speed of the target text content and the target image frame when the playing speed of the target text content is higher, so that the user can obtain the complete target text content.
Optionally, since the playing durations corresponding to the image frames in the video are often the same, for example, one image frame often corresponds to a preset number of milliseconds, based on this, the playing duration of the target image frame corresponding to the target text content in the video to be played is determined, specifically, the number of the target image frames may be determined, and the playing duration of the target image frame is determined based on the number of the target image frames.
Optionally, when the video to be played is ready to be played after being loaded on the player, the start playing time and the end playing time of the video to be played may be obtained, and more specifically, the start playing time and the end playing time of each image frame of the video to be played may also be obtained.
102, determining the complexity of target character content based on the playing time of a target image frame and the number of characters in the target character content;
it should be understood that the target text content can be obtained by scanning each image frame of the video to be played through an artificial intelligence text recognition technology based on deep learning, and can also be obtained by combining with a subtitle file of the video to be played. After the target text content is obtained, in order to determine the text playing speed of the target text, the target text content may be subjected to word segmentation to obtain the number of texts in the target text content.
It should be understood that, when performing word segmentation on the target text content, the space and punctuation marks in the target text content may be removed in units of text characters in the target text content, and the number of text characters after the space and punctuation marks are removed is taken as the number of texts in the target text content. When the target text content contains Chinese characters, the number of the Chinese characters is taken as the number of the characters in the target text content; when the target character content contains English characters, the number of English words is taken as the number of characters in the target character content; when the target text content contains bilingual characters in chinese and english, the number of system languages (for example, the system language is chinese) of the device playing the video to be played should be the number of texts in the target text content.
Because different character quantity determining modes can be adopted based on the language types (such as Chinese characters and English characters) in the target character content, the character complexity in videos of different language types can be accurately determined, and the film watching experience of a user when watching videos of different language types is further ensured.
Optionally, since many objects appearing for the first time, such as people and animals of non-common sense, usually have text descriptions attached to the objects, such as names of people and types of animals, when the video is played, in this case, in order to accurately determine the amount of text displayed, the target text content in the embodiment of the present invention may further include text information of the object introduction in the target image frame.
Optionally, since the objects appearing for the first time in the video, such as the object introduction characters of the characters and the animals of non-common sense class, are often displayed only when the objects appear for the first time, and are often not displayed when the objects appear for the second time, in this case, in order to avoid the user forgetting the roles of the objects, the embodiment of the present invention may convert the object introduction character information into an audio file, establish a mapping relationship between the audio file and the corresponding objects in the video to be played, and play the audio file when the user clicks or presses the objects for a long time. Then, when the target text content includes at least one of subtitle text and object introduction text information, the method further includes:
identifying object introduction text information in the target text content;
identifying a target object matched with the object introduction character information from the target image frame;
converting the object introduction text information into an audio file, and establishing a first mapping relation between the audio file and the target object;
receiving a first input of a target object by a user;
in response to a first input, the audio file is played.
The first input comprises input modes such as clicking, long pressing, sliding and the like.
Optionally, after identifying the target object matching the object introduction text information from the target image frame, a mapping relationship between the object introduction text information and the target object may be established, and when the user clicks or presses the objects for a long time, the object introduction file information is displayed, and then the method further includes:
establishing a second mapping relation between the object introduction text information and the target object;
receiving a second input of the target object by the user;
in response to the second input, the object introduction text information is displayed.
The second input comprises input modes such as clicking, long pressing, sliding and the like.
And 103, adjusting the playing time of the target image frame and the playing time of the target text content based on the complexity of the target text content and a preset complexity threshold.
The preset complexity threshold is determined based on the number of the words read by a preset number of users in a preset time period.
The preset complexity threshold value can be determined based on the word reading number of the preset number of users in the preset time period, and the playing time of the target image frame and the playing time of the target word content are adjusted based on the complexity of the target word content and the preset complexity threshold value, so that the playing time of the target image frame and the playing time of the target word content are adjusted by effectively utilizing the reading capability of the users, and the adjusted playing time of the target image frame and the adjusted playing time of the target word content are more in line with the reading habit of the users.
Optionally, since the text information that the brain can receive in the preset time period is often limited, if the number of the text in the target text content included in the target image frame is too large, the user often cannot see clearly, that is, cannot acquire all the text content included in the image frame, which affects the understanding of the user on the video. Taking the target text content as an example that the target text content simultaneously includes a chinese subtitle and an english subtitle, in this case, since the capability of simultaneously reading the chinese subtitle and the english subtitle within a unit time of the user is limited, in order to ensure that the user can obtain all text information in the target text content, the preset complexity threshold in the embodiment of the present invention includes a first preset complexity threshold and a second preset complexity threshold, where the first preset complexity threshold is smaller than the second preset complexity threshold, for example, the second preset complexity threshold may be a preset multiple of the first preset complexity threshold.
Then, based on the complexity of the target text content and a preset complexity threshold, adjusting the playing time of the target image frame and the playing time of the target text content includes:
under the condition that the complexity of the target text content is greater than or equal to a first preset complexity threshold, based on the playing stopping time of the target image frame, the complexity of the target text content, the difference value between the first preset complexity threshold and a preset slow-down parameter, the playing time of the target image frame and the playing time of the target text content are prolonged;
and under the condition that the complexity playing speed of the target text content is greater than or equal to a second preset complexity threshold value, pausing playing the video to be played.
And under the condition that the complexity of the target text content is greater than or equal to a first preset complexity threshold, based on the playing stopping time of the target image frame, the complexity of the target text content, the difference value between the first preset complexity threshold and a preset slow-down parameter, the playing time length of the target image frame and the playing time length of the target text content are prolonged. On one hand, when the user watches the video, the user can be ensured to clearly see the target character content on the video picture; on the other hand, according to the complexity of the target text content, the difference value between the first preset complexity threshold value and the preset slow-down parameter, the playing time length of the target image frame and the playing time length of the target text content are prolonged, and compared with the original constant playing, the video watching experience of a user is improved.
Optionally, since the start playing time and the end playing time of the target image frame can be obtained, after the end playing time of the target image frame is reached, the next image frame of the target image frame is played, and at this time, the target text content corresponding to the target image frame also disappears in the video playing picture. That is to say, the playing time axis of the target text content can be adjusted according to the playing stop time of the target image frame, the complexity of the target text content, the difference between the first preset complexity thresholds and the preset slowing-down parameter.
Then, based on the stop playing time of the target image frame, the complexity of the target text content, the difference between the first preset complexity threshold and the preset slow-down parameter, the method for prolonging the playing time of the target image frame and the playing time of the target text content includes:
delaying the playing stopping time E ' of the target image frame and the playing stopping time E ' of the target character content according to a formula E ' = E + A multiplied by beta;
wherein, E is the moment when the target image frame stops playing, a is the difference between the complexity of the target text content and a first preset complexity threshold, and β is a preset slowing parameter.
Assuming that the number of words that the brain can read in 1 second is 10, a first preset complexity threshold can be set to 10 characters/second, a second preset complexity threshold is set to 50 characters/second, and a mitigation coefficient is set to β, where β ∈ (0, 1), assuming β = 0.1. The process of determining the complexity of the target textual content S then includes:
firstly, segmenting a target character content S;
if the characters in the target character content are Chinese, one Chinese can be used as a vocabulary; if the characters in the target character content are English, one English word can be used as a vocabulary;
then, obtaining word segmentation results of { A1, A2, A3, … …, Ax }, and counting to obtain the number of characters in the group as N;
and finally, determining the complexity L = N × α, wherein α =1/10, and if L is greater than or equal to 10 characters/second, delaying the playing stop time of the target image frame and the playing stop time of the target text content to be E' = E + A × β = E +0.1A according to a preset slow-down parameter 0.1, wherein E is the playing stop time of the target image frame and the target text content, and A is the difference between the complexity of the target text content and a first preset complexity threshold.
It should be understood that, after delaying the end playing time of the target image frame and the target text content according to the preset slow-down parameter, in order not to affect the normal playing of the image frame after the target image frame in the video to be played, the start playing time and the end playing time of each image frame after the target image frame in the video to be played should be correspondingly delayed.
In the embodiment of the invention, the playing time of the target image frame including the target text content in the video to be played can be obtained, the complexity of the target text content is determined based on the playing time of the target image frame and the number of the characters in the target text content, and finally the playing time of the target image frame and the target text content is adjusted based on the complexity of the target text content and a preset complexity threshold. Therefore, when the text contents corresponding to certain image frames in the video watched by the user are excessive, the playing time of the image frames and the corresponding target text contents can be automatically adjusted according to the complexity of the text contents and the preset complexity threshold value, the user can be ensured to clearly see and acquire the text contents in the image frames, and convenient experience is provided for the user to efficiently acquire the text contents in the video.
