Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.
It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
The term "include" and variations thereof as used herein are open-ended, i.e., "including but not limited to". The term "based on" is "based, at least in part, on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions for other terms will be given in the following description.
It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence relationship of the functions performed by the devices, modules or units.
It is noted that references to "a", "an", and "the" modifications in this disclosure are intended to be illustrative rather than limiting, and that those skilled in the art will recognize that "one or more" may be used unless the context clearly dictates otherwise.
The names of messages or information exchanged between devices in the embodiments of the present disclosure are for illustrative purposes only, and are not intended to limit the scope of the messages or information.
In the related art, the following two subtitle segmentation schemes are provided: the first scheme is as follows: the user directly and manually modifies and adds the identified subtitles, for example, the subtitle "today weather is really good and i want to go out and play" automatically identified by the video clipping tool is deleted to "today weather is really good" by the user, and then a subtitle "i want to go out and play" is manually added. Scheme II: the original caption automatically recognized by the video clipping tool is simply copied once, and then the user is required to manually delete redundant characters respectively, for example, the original caption of "today's weather is really good and I wants to go out to play" is copied once to form two identical captions of "today's weather is really good and I wants to go out to play (caption one)" and "today's weather is really good and I wants to go out to play (caption two)", then the user manually deletes the second half segment of the caption one to become "today's weather is really good (caption one)", and then manually deletes the first half segment of the caption two to become "I wants to go out to play (caption two)", thereby forming two captions. However, the first solution does not provide convenient operation and completely requires manual processing by the user, and the second solution can provide the "splitting" function and still requires the user to manually delete the redundant text. Therefore, there is a need for an improvement of the above scheme to simply and rapidly perform subtitle segmentation.
Fig. 1 is a flowchart of a subtitle segmentation method according to an embodiment of the present disclosure, where the method may be applied to a case of segmenting a recognized video subtitle, and the method may be executed by a subtitle segmentation apparatus, which may be composed of hardware and/or software and may be generally integrated in a device with a subtitle segmentation function, where the device may be an electronic device such as a server, a mobile terminal, or a server cluster. As shown in fig. 1, the method specifically includes the following steps:
Specifically, when a user wants to divide a certain subtitle, a subtitle division instruction is usually input in a user interface, and a subtitle division pointer is slid to a position region to be divided in the subtitle, wherein the user can slide the subtitle division pointer randomly among the subtitles to be divided according to the division requirement. The subtitle segmentation instruction may be a "segmentation" button clicked by a user on a user interface, or a voice segmentation instruction input by the user.
In the embodiment of the present disclosure, the target caption may be understood as a caption to be segmented by a user, where the target caption may include a plurality of characters, and each character in the target caption is stored in a corresponding view container. The view container may be understood as a container unit that can be displayed on the user interface and is used for containing characters, the number of the characters contained in the target subtitle is the same as the number of the view containers, and it may be understood that each character in the target subtitle corresponds to one fixed view container, that is, the view containers correspond to the characters contained in the target subtitle in a one-to-one manner. The size of each view container may be the same or different, and the size of each view container is not limited in the embodiments of the present disclosure. Illustratively, the target subtitle is "invisible and therefore can accept a bar", and fig. 2 is a schematic view of the target subtitle stored in the view container.
In the embodiment of the disclosure, when a subtitle segmentation instruction input by a user is received, a view container covered by a subtitle segmentation pointer corresponding to the subtitle segmentation instruction is determined from each view container, and the view container covered by the subtitle segmentation pointer is used as a target view container. For example, fig. 3 is a schematic diagram of a subtitle segmentation pointer in a view container where a target subtitle is located, and as shown in fig. 3, the subtitle segmentation pointer is overlaid on the view container where the character "still" is located, and the view container where the character "still" is located is taken as the target view container.
It should be noted that, the arrangement manner of the view containers is not limited in the embodiments of the present disclosure, where the view containers may be arranged longitudinally (for example, vertical subtitles), or arranged transversely (for example, horizontal subtitles), and of course, may be arranged at any angle to adapt to the subtitle presenting manners at different angles.
And step 130, segmenting the target subtitle according to the position relation between the subtitle segmentation pointer and the target view container.
In the embodiment of the present disclosure, the position relationship between the subtitle segmentation pointer and the target view container is determined, and the target subtitle is segmented according to the position relationship between the subtitle segmentation pointer and the target view container. It can be understood that the subtitle division pointer has a different positional relationship with the target view container, and the division manner of the target subtitle is different. For example, if the view containers are arranged horizontally, when the subtitle segmentation pointer is located at the left half of the target view container, all characters before (excluding the target character) the target character in the target view container may be segmented from the target character and all characters after the target character; when the subtitle division pointer is located on the right half of the target view container, the target character in the target view container and all characters before and after the target character (excluding the target character) can be divided.
Optionally, segmenting the target subtitle according to the position relationship between the subtitle segmentation pointer and the target view container, including: determining the segmentation position of the target subtitle according to the position relationship between the subtitle segmentation pointer and the target view container; segmenting the target subtitle based on the determined segmentation position.
According to the technical scheme of the embodiment of the disclosure, a subtitle segmentation instruction input by a user is received; determining a target view container covered by a subtitle segmentation pointer corresponding to the subtitle segmentation instruction from each view container; wherein, the view container corresponds to the characters contained in the target caption one by one; and segmenting the target subtitle according to the position relation between the subtitle segmentation pointer and the target view container. According to the subtitle segmentation method provided by the embodiment of the disclosure, as each character in the target subtitle to be segmented is placed in the corresponding view container one by one, the position relationship between the character segmentation pointer and the covered view container can be quickly determined, so that the subtitle can be simply and quickly segmented according to the position relationship, the extra manual operation of a user is effectively reduced, and the user experience is greatly improved.
In some embodiments, segmenting the target subtitle according to the position relationship between the subtitle segmentation pointer and the target view container includes: determining the segmentation position of the target subtitle according to the position relationship between the subtitle segmentation pointer and the target view container; segmenting the target subtitle based on the determined segmentation position. Because the position relationship between the subtitle segmentation pointer and the target view container is different, the determined segmentation position of the target character is different, and correspondingly, the segmentation mode of the target subtitle is different, the segmentation position of the target subtitle can be further determined according to the position relationship between the subtitle segmentation pointer and the target view container, and then the target subtitle is segmented according to the segmentation position.
Optionally, determining the segmentation position of the target subtitle according to the position relationship between the subtitle segmentation pointer and the target view container includes: respectively determining a first distance between the subtitle segmentation pointer and a first edge of the target view container and a second distance between the subtitle segmentation pointer and a second edge of the target view container; wherein the first edge is an adjacent edge of a previous view container of the target view container and the target view container, and the second edge is an adjacent edge of a subsequent view container of the target view container and the target view container; and determining the segmentation position of the target subtitle according to the size relation between the first distance and the second distance. The method has the advantages that the segmentation position of the target subtitle can be accurately and quickly determined, and the target subtitle can be accurately and quickly segmented.
For example, since the width of the target view container is fixed, the division position of the target subtitle may be further determined by calculating the distance between the subtitle division pointer and each edge of the target view container. Specifically, the adjacent edge of the previous view container of the target view container and the target view container is used as a first edge, the adjacent edge of the next view container of the target view container and the target view container is used as a second edge, the distances between the subtitle segmentation pointer and the first edge and between the subtitle segmentation pointer and the second edge are respectively calculated, the distance between the subtitle segmentation pointer and the first edge is used as a first distance, and the distance between the subtitle segmentation pointer and the second edge is used as a second distance. Then, the first distance and the second distance are compared, and the segmentation position of the target subtitle is determined according to the size relation of the first distance and the second distance.
Optionally, determining the segmentation position of the target subtitle according to the relationship between the first distance and the second distance includes: when the first distance is smaller than the second distance, determining the position between a target character in a target view container and a character before the target character as the segmentation position of the target caption; and when the first distance is greater than the second distance, determining the position between a target character in a target view container and a character next to the target character as the segmentation position of the target subtitle.
Illustratively, when the first distance is smaller than the second distance, the position between the target character and the character before the target character in the target view container is determined as the segmentation position of the target caption, and accordingly, when the target caption is segmented according to the determined segmentation position, the first caption is formed based on all characters before the target character in the target view container, and the second caption is formed based on the target character and all characters after the target character. When the first distance is larger than the second distance, determining the position between the target character in the target view container and the character next to the target character as the segmentation position of the target caption, correspondingly, when the target caption is segmented according to the determined segmentation position, forming a first caption based on the target character in the target view container and all characters in front of the target character, and forming a second caption based on all characters behind the target character.
The subtitle division manner described above will be explained by taking the horizontal arrangement of the view containers as an example. When the first distance is smaller than the second distance, the subtitle segmentation pointer is positioned at the left half side of the target view container, and the position between the target subtitle in the target view container and the subtitle adjacent to the left side of the target subtitle is determined as the segmentation position of the target subtitle; and when the first distance is smaller than the second distance, the subtitle segmentation pointer is positioned on the right half side of the target view container, and the position between the target subtitle in the target view container and the subtitle adjacent to the right of the target subtitle is determined as the segmentation position of the target subtitle. Illustratively, the subtitle segmentation pointer is positioned at the left half of the character 'can' in the target subtitle, the character 'can' is taken as the target character, the character 'can' before the target character 'can' is cut from the character 'can' before the target character 'can' and all characters behind the target character 'can' be cut from the target character 'can' to receive the bar ', namely the character' can 'in the target subtitle can' not be seen from the target character and the character 'can' be cut from the target character 'can' to form two subtitles, so as to realize the segmentation of the target subtitle. As another example, if the subtitle segmentation pointer is located on the half of the character "can" in the target subtitle, the character "can" is also used as the target character, and the target character "can" and all characters "behind the target character" can be segmented from the character "can" because the character "can" and the target character "can not see the character" so that the character "can" and all characters "behind the target character" can be segmented from each other, that is, the character "can not see the character" can "and the character" can be segmented from each other in the target subtitle, so that two subtitles are formed, and the target subtitle is segmented.
In some embodiments, the segmenting the target subtitle based on the determined segmentation position includes: determining a first subtitle and a second subtitle from the target subtitle based on the determined division position; and respectively storing all characters in the first caption and all characters in the second caption in two different array structures. The characters contained in the two subtitles divided by the user for the target subtitle are respectively stored in two different data structures (that is, all the characters in the divided first subtitle and second subtitle are respectively stored in two different array structures), so that the subtitle formed by the characters stored in each data structure can be used as a new target subtitle again, and the new target subtitle is divided continuously according to the position relation between the target view container covered by the subtitle dividing pointer corresponding to the subtitle dividing instruction input by the user and the subtitle dividing pointer. Therefore, multiple groups of characters split from the initial target caption can be respectively stored in multiple different data group structures, and small captions obtained by splitting the target caption are stored in each data group structure, so that the target caption can be split into multiple small captions.
In some embodiments, after the segmenting the target subtitle based on the determined segmentation position, the method further comprises: and increasing the distance between the first caption and the second caption obtained by segmentation. The method has the advantages that the visual effect of the user after the target subtitle is segmented can be increased, and the segmentation result is clear for the user. Illustratively, when the target subtitle "cannot see him and can also receive bar" is divided to "cannot see him and" can receive bar "based on the determined division position, the distance between the character" can "and the character" can "is increased. Optionally, increasing the distance between the first subtitle and the second subtitle obtained by the segmentation includes: and increasing the distance between the view container in which the last character in the first subtitle is positioned and the view container in which the first character in the second subtitle is positioned. For example, the margin between the view container where the character "still" is located and the view container where the character "can" is located is increased, so that it is possible to clearly know at which position the target subtitle is divided, so that the division result is clear.
Optionally, increasing the distance between the first subtitle and the second subtitle obtained by the segmentation includes: and when a view list refreshing instruction input by a user is received, increasing the distance between the first subtitle and the second subtitle obtained by segmentation. Wherein, when receiving the 'refresh' button clicked by the user, the method indicates that the view list refresh command is received, or when receiving the refresh command input by the user in the form of voice, the method indicates that the view list refresh command is received. And when a view list refreshing instruction is received, increasing the distance between the first subtitle and the second subtitle obtained by segmentation.
In some embodiments, before receiving a subtitle segmentation instruction input by a user, the method further includes: acquiring a target subtitle identified from a target video; and respectively placing each character in the target caption into a corresponding view container and displaying the characters in a user interface. The target video may include a video recorded on site, a video selected from a terminal album, or a video loaded from a network side, and it should be noted that the source of the target video is not limited in the embodiments of the present disclosure. Optionally, the target video is acquired, the voice in the target video is recognized, and the recognized voice information may be correspondingly configured in the image frame corresponding to the target video in the form of subtitles. Of course, the number of subtitles identified from the target video may include a plurality of subtitles, and one subtitle may be selected from the plurality of subtitles as the target subtitle, for example, the longest subtitle with a subtitle length greater than a preset length threshold may be used as the target subtitle, and one subtitle may be selected from the plurality of subtitles as the target subtitle according to a selection instruction of a user. It should be noted that, the embodiment of the present disclosure does not limit the manner of determining the target subtitle from the subtitles recognized in the target video. And respectively placing each character in the target caption into a corresponding view container, wherein each view container corresponds to each character in the target caption one by one.
In some embodiments, before placing each character in the target subtitle in the corresponding view container, the method further includes: storing all characters in the target caption in an array structure; placing each character in the target caption in a corresponding view container respectively, including: and reading each character in the target caption from the array structure in sequence, and respectively placing each character in the target caption in a corresponding view container.
Illustratively, after a target subtitle identified from a target video is acquired, each character in the target subtitle is stored in an array structure, when the target subtitle needs to be displayed on a user interface, each character in the target subtitle is sequentially read from the array structure and is respectively placed in a corresponding view container, wherein one character is correspondingly placed in one view container. Because each character in the target caption is stored in the same array structure in advance, the target caption can be segmented for multiple times according to the caption segmentation instructions input by a user for multiple times, and the effect of 'one caption and multiple segmentation' is achieved.
In some embodiments, before obtaining the target subtitles identified from the target video, the method further comprises: acquiring a video to be edited; determining the playing time length of the video to be clipped; when the playing duration is longer than a preset playing duration, clipping the video to be clipped to generate the target video; and the playing time length of the target video is less than or equal to the preset playing time length. Specifically, when a certain video needs to be edited, the video to be edited is acquired, for example, the video to be edited is selected from a local album, or a certain video is loaded from the network side as the video to be edited. And determining the playing time length of the video to be clipped, clipping the video to be clipped when the playing time length of the video to be clipped is greater than the preset playing time length, controlling the playing time length of the clipped video to be less than or equal to the preset playing time length, and taking the clipped video as the target video. When the video to be clipped is clipped to generate the target video, the initial playing time, the ending playing time and the playing content of the target video in the video to be clipped can be determined according to the user selection, and of course, the video to be clipped can also be automatically clipped, for example, the initial playing time of the video to be clipped is used as the initial playing time of the target video, and the video to be clipped is clipped as the target video with the playing duration being the preset playing duration. When the playing duration of the video to be clipped is less than the preset playing duration, the video to be clipped is directly used as the target video without clipping operation, and is released.
Optionally, when the playing duration is longer than a preset playing duration, clipping the video to be clipped to generate the target video, including: when the playing duration is longer than a preset playing duration, prompting a user whether to clip the video to be clipped; when a clipping instruction input by the user is received, clipping the video to be clipped according to the clipping instruction, and generating the target video. The advantage of this arrangement is that the user's real needs for the video clip can be better met. Specifically, when the playing duration of the video to be clipped is longer than the preset playing duration, the user is prompted whether to clip the video to be clipped, for example, the user is prompted whether to clip the video to be clipped in a voice mode or a text mode. When a clipping instruction input by a user is received, clipping a video to be clipped according to the clipping instruction. The clipping instruction may include a start time of clipping the video to be clipped, a playing time of the clipped video, and an end time of clipping. Then, the clipped video is taken as the target video, and of course, the target video may be distributed. Optionally, when a clipping instruction input by a user is not received within a preset time period, the video to be clipped may be directly used as the target video and issued.
