Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
图1示出了根据本发明一个实施例的为视频添加弹幕的方法的流程示意图。如图1所示，该方法包括：Fig. 1 shows a schematic flowchart of a method for adding barrage to a video according to an embodiment of the present invention. As shown in Figure 1, the method includes:
步骤S110，识别指定视频的内容，获得识别结果。Step S110, identifying the content of the specified video and obtaining the identification result.
在本实施例中，为了使得添加的弹幕更加匹配该指定视频，首先需要识别指定视频的内容，如该视频的分类、场景画面变化等，以便根据识别到的内容进行弹幕文字内容的获取。In this embodiment, in order to make the added bullet chat better match the specified video, it is first necessary to identify the content of the specified video, such as the classification of the video, scene picture changes, etc., so as to obtain the text content of the bullet chat according to the identified content .
步骤S120，根据识别结果获取相应的文字信息。Step S120, acquiring corresponding text information according to the recognition result.
步骤S130，将获取的文字信息作为弹幕内容添加到指定视频的相应位置处。Step S130, adding the acquired text information as bullet chat content to the corresponding position of the designated video.
这里的相应位置可以是根据需求在本实施例中，根据指定视频的内容自动添加弹幕，不需要用户手动添加，增加视频互动性，避免影响用户观看视频的质量，增强用户的使用体验。The corresponding position here can be based on requirements. In this embodiment, the barrage is automatically added according to the content of the specified video, without the need for the user to add it manually, increasing video interactivity, avoiding affecting the quality of the video watched by the user, and enhancing the user experience.
下面对指定视频的内容的多种识别方式进行详细说明，进而为指定视频添加弹幕。The following is a detailed description of multiple identification methods for the content of the specified video, and then adding a barrage to the specified video.
在本发明的一个实施例中，步骤S110中的识别指定视频的内容，获得识别结果包括：根据预设的分类信息识别指定视频的内容所属的分类，获得指定视频的内容的分类信息。In one embodiment of the present invention, identifying the content of the specified video in step S110 and obtaining the recognition result includes: identifying the category to which the content of the specified video belongs according to preset classification information, and obtaining the classification information of the content of the specified video.
在本实施例中，对指定视频内容的分类进行识别，具体是识别指定视频的内容所属的预设的分类中的哪一种。In this embodiment, the classification of the specified video content is identified, specifically, which of the preset classifications the content of the specified video belongs to is identified.
具体地，上述的预设的分类信息包括如下中的一种或多种：喜剧类、恐怖类、悲剧类、舞蹈类、唱歌类、儿童类、战争类。Specifically, the aforementioned preset classification information includes one or more of the following: comedy, horror, tragedy, dance, singing, children, and war.
需要说明的是，上述的预设的分类信息是优选的实施例。但是预设的分类信息不应限于上述列举出来的分类。It should be noted that the above preset classification information is a preferred embodiment. However, the preset classification information should not be limited to the classifications listed above.
进一步地，步骤S120中的根据识别结果获取相应的文字信息包括：根据预设的分类信息，为各分类分别确定相匹配的文字信息，并保存；根据指定视频的内容所属的分类信息获取所保存的相匹配的文字信息。Further, obtaining the corresponding text information according to the recognition result in step S120 includes: according to the preset classification information, respectively determining matching text information for each classification and saving them; obtaining the saved text information according to the classification information to which the specified video content belongs matching text information.
也就是说，当识别到指定视频的内容所属的分类信息后，为了添加与分类信息匹配的弹幕，就要获取与该指定视频的内容所述的分类信息匹配的文字信息。在本实施例中，首先是根据预设的分类信息确定对应的文字信息，以便当识别到指定视频的内容所述的分类信息后就可以进行相应分类的文字信息的获取。例如，对恐怖类的，确定相匹配的文字信息是“好恐怖啊”；对喜剧类的，确定相匹配的文字信息是“好搞笑”等。That is to say, after identifying the category information to which the content of the specified video belongs, in order to add a barrage that matches the category information, it is necessary to obtain text information that matches the category information described in the content of the specified video. In this embodiment, first, the corresponding text information is determined according to the preset classification information, so that the corresponding classification text information can be obtained after the classification information described in the content of the specified video is recognized. For example, for the horror category, it is determined that the matching text information is "so scary"; for the comedy category, it is determined that the matching text information is "so funny".
在一个例子中，识别到指定视频的内容所述的分类信息是喜剧类，那么根据该指定视频的内容所述的分类信息获取保存的相匹配的文字信息是“好搞笑”。那么就可以将获取到的文字信息“好搞笑”作为弹幕添加到该指定视频的相应位置处。In one example, if it is identified that the classification information described in the content of the specified video is comedy, then the matching text information stored according to the classification information described in the content of the designated video is "so funny". Then, the acquired text message "so funny" can be added to the corresponding position of the specified video as a barrage.
优选地，这里对指定视频的内容的所属的分类信息的识别可以仅对指定视频的关键帧进行识别，以提高识别速度。Preferably, the identification of the classification information of the content of the specified video may only identify the key frames of the specified video, so as to improve the identification speed.
在本发明的一个实施例中，步骤S110中的识别指定视频的内容，获得识别结果包括：通过检测判断指定视频中是否存在场景变化符合预设条件的时段，是则获取预设的与场景变化对应的文字信息。In one embodiment of the present invention, identifying the content of the specified video in step S110, and obtaining the recognition result includes: determining whether there is a time period in which the scene change meets the preset condition in the specified video through detection, and if so, obtain the preset scene change corresponding text information.
在本实施例中，对指定视频内容的场景变化进行识别，以便根据场景变化添加匹配的弹幕。通常情况下，在指定视频的情节变化较大时，用户有添加弹幕的需求，所以，这里主要是为了识别指定视频中的场景变化较大的时段，以便获取对应的文字信息。In this embodiment, the scene change of the specified video content is identified, so as to add a matching barrage according to the scene change. Usually, when the plot of the specified video changes greatly, the user needs to add bullet chatting. Therefore, this is mainly to identify the period of time when the scene in the specified video changes greatly, so as to obtain the corresponding text information.
进一步地，步骤S130中的将获取的文字信息作为弹幕内容添加到指定视频的相应位置处包括：将获取的文字信息作为弹幕内容添加到指定视频中的场景变化符合预设条件的时段处。Further, in step S130, adding the acquired text information as the barrage content to the corresponding position of the specified video includes: adding the acquired text information as the barrage content to the time period when the scene change in the specified video meets the preset condition .
因为本实施例中，获取的是与场景变化对应的文字信息，所以在添加的时候需要对应到指定视频中的场景变化的时段，才能达到场景发生变化，相应的弹幕出现的效果，而非是将获取的文字信息随意添加，进一步提高用户的使用体验。Because in this embodiment, the text information corresponding to the scene change is obtained, so when adding it, it needs to correspond to the time period of the scene change in the specified video, so as to achieve the effect of the scene changing and the corresponding barrage appearing instead of It is to add the obtained text information at will to further improve the user experience.
具体地，上述的通过检测判断指定视频中是否存在场景变化符合预设条件的时段包括：通过检测指定视频画面中的指定颜色的变化速度，判断指定视频中是否存在画面变化速度符合预设条件的时段；和/或，通过检测指定视频的对应音频的节奏变化速度，判断指定视频中是否存在配乐节奏变化速度符合预设条件的时段。Specifically, the above-mentioned period of detecting whether there is a scene change meeting the preset condition in the specified video includes: by detecting the change speed of the specified color in the specified video picture, judging whether there is a time period in the specified video whose picture change speed meets the preset condition time period; and/or, by detecting the rhythm change speed of the corresponding audio of the specified video, it is judged whether there is a time period in the specified video where the rhythm change speed of the soundtrack meets the preset condition.
指定视频中场景变化可以直接体现在颜色或者对应的背景音频的节奏上，例如，恐怖类的指定视频中，当恐怖的场景出现时，往往会配有快节奏的音频或者音频的节奏从舒缓到剧烈；舞蹈类的视频中，舞台背景颜色会随着舞蹈动作的变换而变换，当舞蹈动作变化较大时，舞台的背景颜色也会相应的出现较大的变化，即指定视频中的背景颜色会发生较大的变化。所以，在本实施例中，检测指定视频中是否存在场景变化时，可以通过指定视频画面中的指定颜色或者对应音频的节奏的变化进行检测。具体地，颜色的变化和/节奏的变化是通过指定颜色变化速度和/或节奏的变化速度来体现的额，因此，检测的也是相应的颜色的变化速度和/或节奏的变化速度。通过检测指定颜色的变化速度和通过检测节奏的变化速度，两种方式可单独使用，也可以相互结合使用。The scene changes in the specified video can be directly reflected in the color or the rhythm of the corresponding background audio. For example, in the specified horror video, when the horror scene appears, it is often equipped with fast-paced audio or the rhythm of the audio changes from soothing to Vigorous; in dance videos, the background color of the stage will change with the change of dance movements. When the dance movements change greatly, the background color of the stage will also change correspondingly. Big changes will happen. Therefore, in this embodiment, when detecting whether there is a scene change in the specified video, the detection may be performed through the change of the specified color in the specified video picture or the rhythm of the corresponding audio. Specifically, the color change and/or the rhythm change are embodied by specifying the color change speed and/or the rhythm change speed, therefore, the corresponding color change speed and/or the rhythm change speed are also detected. By detecting the change speed of the specified color and by detecting the change speed of the rhythm, the two methods can be used independently or in combination with each other.
在本发明的一个实施例中，图1所示的方法进一步包括：获取用户对该指定视频的评论信息；将评论信息作为弹幕内容添加到指定视频的相应位置处。In an embodiment of the present invention, the method shown in FIG. 1 further includes: acquiring user comment information on the specified video; and adding the comment information as barrage content to the corresponding position of the specified video.
在实际应用中，用户可以通过评论的方式表达自己的想法，并非是通过弹幕的方式，因此，为了保证指定视频的更好的用户互动性，在本实施例中，当用户对指定视频进行评论时，还可以将评论信息作为弹幕添加到指定视频中。例如，用户在观看一指定视频时，在指定视频的评论区发表了评论“这个视频值得一看”，那么当该用户发表评论后，就可以将评论“该视频值得一看”作为弹幕添加到指定视频中，以便其他用户可以直接获取到该用户的想法。In practical applications, users can express their thoughts through comments, not through barrage. Therefore, in order to ensure better user interaction of the specified video, in this embodiment, when the user makes a comment on the specified video When commenting, the comment information can also be added to the specified video as a barrage. For example, when a user watches a specified video, he comments "this video is worth watching" in the comment area of the specified video, then after the user makes a comment, the comment "this video is worth watching" can be added as a barrage to a given video, so that other users can get the user's thoughts directly.
进一步地，步骤S130中的将评论信息作为弹幕内容添加到指定视频的相应位置处包括：根据指定视频播放时评论信息的生成时间点，将该评论信息作为弹幕添加到指定视频的相应的时间点处；或者，将评论信息作为弹幕内容添加到指定视频的与评论信息相匹配的内容所在的位置处。Further, in step S130, adding the comment information as a barrage content to the corresponding position of the specified video includes: adding the comment information as a barrage to the corresponding position of the specified video according to the generation time point of the comment information when the specified video is played. or, add the comment information as barrage content to the position where the content matching the comment information of the specified video is located.
用户在观看指定视频时，可能会实时对指定视频进行评论，为了作为弹幕的用户评论与指定视频的场景相对应，根据评论信息的生成时间或者内容，相对应的添加。例如，当用户观看到指定视频的第2分钟的时候，视频场景中的人物说了句名言，用户认为该名言非常经典，会在评论区发表评论信息“这句话太经典了”，那么为了使得该用户的评论信息与指定视频的场景相对应，根据该评论信息“这句话太经典了”生成的时间点是指定视频的第2分钟，那么就将该评论信息“这句话太经典了”作为弹幕添加到指定视频的第2分钟处。When a user watches a specified video, they may comment on the specified video in real time. In order to correspond to the scene of the specified video, user comments as bullet chatting are added correspondingly according to the generation time or content of the comment information. For example, when the user watches the second minute of the specified video, a character in the video scene utters a famous quote, and the user thinks the famous quote is very classic, and will post a comment message "This sentence is too classic" in the comment area, then for Make the user's comment information correspond to the scene of the specified video, and the time point generated according to the comment information "This sentence is too classic" is the second minute of the specified video, then the comment information "This sentence is too classic"了” is added as a barrage at the 2nd minute of the specified video.
或者，获取的用户评论信息可以作为弹幕的素材，当指定视频中的内容与评论信息相匹配的时候，可以将评论信息作为弹幕添加到指定视频对应的内容位置处，在这里不限于该评论信息的生成时间，只要内容相匹配就可以。例如，沿用上一个例子，用户在第2分钟发表了评论信息“这句话太经典了”，但是在对指定视频的内容进行识别时，识别到在第10分钟的内容中也出现了类似的经典名言，那么就可以将用户在第2分钟发表的评论信息“这句话太经典了”作为弹幕添加在指定视频的第10分钟处。Or, the obtained user comment information can be used as the material of the bullet chatting. When the content in the specified video matches the comment information, the comment information can be added as a bullet chatting to the content position corresponding to the specified video. It is not limited to this The generation time of comment information, as long as the content matches. For example, following the previous example, the user posted a comment message "This sentence is too classic" in the 2nd minute, but when identifying the content of the specified video, it was recognized that a similar sentence appeared in the 10th minute content Classic quotes, then the comment message "This sentence is too classic" posted by the user in the 2nd minute can be added as a barrage at the 10th minute of the specified video.
图2示出了根据本发明另一个实施例的为视频添加弹幕的方法的流程示意图。如图2所示，为视频添加弹幕的方法具体为：首先预设内容识别、场景变化以及视频分类的识别算法，对于一视频，对视频进行预设的算法识别，即内容识别、场景变化识别和视频分类，得到识别结果，获得识别结果后，一方面根据关键帧的识别结果和内容生成文字信息，如“高能预警、精彩、666”等，生成的文字信息作为弹幕，即弹幕生成，添加到指定视频中即可；另一方面，当用户进行评论后，将用户评论与视频进行匹配(这里匹配即是时间点匹配或内容匹配)，将用户评论作为弹幕(即弹幕生成)，添加到指定视频中对应的位置。Fig. 2 shows a schematic flowchart of a method for adding barrage to a video according to another embodiment of the present invention. As shown in Figure 2, the method of adding barrage to a video is as follows: first, preset content recognition, scene change and video classification recognition algorithms, and for a video, perform preset algorithm recognition on the video, that is, content recognition, scene change Recognition and video classification to obtain the recognition results. After obtaining the recognition results, on the one hand, text information is generated according to the recognition results and content of key frames, such as "high-energy warning, wonderful, 666", etc., and the generated text information is used as a barrage, that is, a barrage Generate and add to the specified video; on the other hand, after the user makes a comment, match the user comment with the video (here matching is time point matching or content matching), and use the user comment as a barrage (ie barrage Generated), added to the corresponding position in the specified video.
图3示出了根据本发明一个实施例的为视频添加弹幕的装置的结构示意图。如图3所示，该为视频添加弹幕的装置300包括：Fig. 3 shows a schematic structural diagram of an apparatus for adding barrage to a video according to an embodiment of the present invention. As shown in Figure 3, the device 300 for adding barrage to video includes:
识别单元310，适于识别指定视频的内容，获得识别结果。The recognition unit 310 is adapted to recognize the content of the specified video and obtain a recognition result.
在本实施例中，为了使得添加的弹幕更加匹配该指定视频，首先需要识别指定视频的内容，如该视频的分类、场景画面变化等，以便根据识别到的内容进行弹幕文字内容的获取。In this embodiment, in order to make the added bullet chat better match the specified video, it is first necessary to identify the content of the specified video, such as the classification of the video, scene picture changes, etc., so as to obtain the text content of the bullet chat according to the identified content .
获取单元320，适于根据识别结果获取相应的文字信息。The obtaining unit 320 is adapted to obtain corresponding text information according to the recognition result.
添加单元330，适于将获取的文字信息作为弹幕内容添加到指定视频的相应位置处。The adding unit 330 is adapted to add the acquired text information to a corresponding position of the specified video as bullet chat content.
这里的相应位置可以是根据需求在本实施例中，根据指定视频的内容自动添加弹幕，不需要用户手动添加，增加视频互动性，避免影响用户观看视频的质量，增强用户的使用体验。The corresponding position here can be based on requirements. In this embodiment, the barrage is automatically added according to the content of the specified video, without the need for the user to add it manually, increasing video interactivity, avoiding affecting the quality of the video watched by the user, and enhancing the user experience.
下面对指定视频的内容的多种识别方式进行详细说明，进而为指定视频添加弹幕。The following is a detailed description of multiple identification methods for the content of the specified video, and then adding a barrage to the specified video.
在本发明的一个实施例中，识别单元310，适于根据预设的分类信息识别指定视频的内容所属的分类，获得指定视频的内容的分类信息。In one embodiment of the present invention, the identifying unit 310 is adapted to identify the category to which the content of the specified video belongs according to preset category information, and obtain the category information of the content of the specified video.
在本实施例中，对指定视频内容的分类进行识别，具体是识别指定视频的内容所属的预设的分类中的哪一种。In this embodiment, the classification of the specified video content is identified, specifically, which of the preset classifications the content of the specified video belongs to is identified.
具体地，上述的预设的分类信息包括如下中的一种或多种：喜剧类、恐怖类、悲剧类、舞蹈类、唱歌类、儿童类、战争类。Specifically, the aforementioned preset classification information includes one or more of the following: comedy, horror, tragedy, dance, singing, children, and war.
需要说明的是，上述的预设的分类信息是优选的实施例。但是预设的分类信息不应限于上述列举出来的分类。It should be noted that the above preset classification information is a preferred embodiment. However, the preset classification information should not be limited to the classifications listed above.
进一步地，获取单元320，适于根据预设的分类信息，为各分类分别确定相匹配的文字信息，并保存；根据指定视频的内容所属的分类信息获取所保存的相匹配的文字信息。Further, the obtaining unit 320 is adapted to determine and store matching text information for each category according to preset classification information; obtain the stored matching text information according to the classification information to which the content of the specified video belongs.
也就是说，当识别到指定视频的内容所属的分类信息后，为了添加与分类信息匹配的弹幕，就要获取与该指定视频的内容所述的分类信息匹配的文字信息。在本实施例中，首先是根据预设的分类信息确定对应的文字信息，以便当识别到指定视频的内容所述的分类信息后就可以进行相应分类的文字信息的获取。例如，对恐怖类的，确定相匹配的文字信息是“好恐怖啊”；对喜剧类的，确定相匹配的文字信息是“好搞笑”等。That is to say, after identifying the category information to which the content of the specified video belongs, in order to add a barrage that matches the category information, it is necessary to obtain text information that matches the category information described in the content of the specified video. In this embodiment, first, the corresponding text information is determined according to the preset classification information, so that the corresponding classification text information can be obtained after the classification information described in the content of the specified video is recognized. For example, for the horror category, it is determined that the matching text information is "so scary"; for the comedy category, it is determined that the matching text information is "so funny".
在一个例子中，识别到指定视频的内容所述的分类信息是喜剧类，那么根据该指定视频的内容所述的分类信息获取保存的相匹配的文字信息是“好搞笑”。那么就可以将获取到的文字信息“好搞笑”作为弹幕添加到该指定视频的相应位置处。In one example, if it is identified that the classification information described in the content of the specified video is comedy, then the matching text information stored according to the classification information described in the content of the designated video is "so funny". Then, the acquired text message "so funny" can be added to the corresponding position of the specified video as a barrage.
在本发明的一个实施例中，识别单元310，适于通过检测判断指定视频中是否存在场景变化符合预设条件的时段，是则获取预设的与场景变化对应的文字信息。In one embodiment of the present invention, the identification unit 310 is adapted to judge whether there is a time period in the specified video where the scene change meets the preset condition by detecting, and if so, acquire the preset text information corresponding to the scene change.
在本实施例中，对指定视频内容的场景变化进行识别，以便根据场景变化添加匹配的弹幕。通常情况下，在指定视频的情节变化较大时，用户有添加弹幕的需求，所以，这里主要是为了识别指定视频中的场景变化较大的时段，以便获取对应的文字信息。In this embodiment, the scene change of the specified video content is identified, so as to add a matching barrage according to the scene change. Usually, when the plot of the specified video changes greatly, the user needs to add bullet chatting. Therefore, this is mainly to identify the period of time when the scene in the specified video changes greatly, so as to obtain the corresponding text information.
进一步地，添加单元330，适于将获取的文字信息作为弹幕内容添加到指定视频中的场景变化符合预设条件的时段处。Further, the adding unit 330 is adapted to add the acquired text information as barrage content to the period of time when the scene change in the specified video meets the preset condition.
因为本实施例中，获取的是与场景变化对应的文字信息，所以在添加的时候需要对应到指定视频中的场景变化的时段，才能达到场景发生变化，相应的弹幕出现的效果，而非是将获取的文字信息随意添加，进一步提高用户的使用体验。Because in this embodiment, the text information corresponding to the scene change is obtained, so when adding it, it needs to correspond to the time period of the scene change in the specified video, so as to achieve the effect of the scene changing and the corresponding barrage appearing instead of It is to add the obtained text information at will to further improve the user experience.
具体地，识别单元310，适于通过检测指定视频画面中的指定颜色的变化速度，判断指定视频中是否存在画面变化速度符合预设条件的时段；和/或，通过检测指定视频的对应音频的节奏变化速度，判断指定视频中是否存在配乐节奏变化速度符合预设条件的时段。Specifically, the recognition unit 310 is adapted to determine whether there is a time period in the specified video where the picture change speed meets the preset condition by detecting the change speed of the specified color in the specified video picture; and/or, by detecting the corresponding audio of the specified video Rhythm change speed, to determine whether there is a period in the specified video where the rhythm change speed of the soundtrack meets the preset conditions.
指定视频中场景变化可以直接体现在颜色或者对应的背景音频的节奏上，例如，恐怖类的指定视频中，当恐怖的场景出现时，往往会配有快节奏的音频或者音频的节奏从舒缓到剧烈；舞蹈类的视频中，舞台背景颜色会随着舞蹈动作的变换而变换，当舞蹈动作变化较大时，舞台的背景颜色也会相应的出现较大的变化，即指定视频中的背景颜色会发生较大的变化。所以，在本实施例中，检测指定视频中是否存在场景变化时，可以通过指定视频画面中的指定颜色或者对应音频的节奏的变化进行检测。具体地，颜色的变化和/节奏的变化是通过指定颜色变化速度和/或节奏的变化速度来体现的额，因此，检测的也是相应的颜色的变化速度和/或节奏的变化速度。通过检测指定颜色的变化速度和通过检测节奏的变化速度，两种方式可单独使用，也可以相互结合使用。The scene changes in the specified video can be directly reflected in the color or the rhythm of the corresponding background audio. For example, in the specified horror video, when the horror scene appears, it is often equipped with fast-paced audio or the rhythm of the audio changes from soothing to Vigorous; in dance videos, the background color of the stage will change with the change of dance movements. When the dance movements change greatly, the background color of the stage will also change correspondingly. Big changes will happen. Therefore, in this embodiment, when detecting whether there is a scene change in the specified video, the detection may be performed through the change of the specified color in the specified video picture or the rhythm of the corresponding audio. Specifically, the color change and/or the rhythm change are embodied by specifying the color change speed and/or the rhythm change speed, therefore, the corresponding color change speed and/or the rhythm change speed are also detected. By detecting the change speed of the specified color and by detecting the change speed of the rhythm, the two methods can be used independently or in combination with each other.
在本发明的一个实施例中，图3所示的装置进一步包括：In one embodiment of the present invention, the device shown in Figure 3 further includes:
评论信息获取单元，适于获取用户对该指定视频的评论信息。The comment information acquisition unit is adapted to acquire user comment information on the specified video.
则添加单元330，适于将评论信息作为弹幕内容添加到指定视频的相应位置处。Then the adding unit 330 is adapted to add the comment information as barrage content to the corresponding position of the specified video.
在实际应用中，用户可以通过评论的方式表达自己的想法，并非是通过弹幕的方式，因此，为了保证指定视频的更好的用户互动性，在本实施例中，当用户对指定视频进行评论时，还可以将评论信息作为弹幕添加到指定视频中。例如，用户在观看一指定视频时，在指定视频的评论区发表了评论“这个视频值得一看”，那么当该用户发表评论后，就可以将评论“该视频值得一看”作为弹幕添加到指定视频中，以便其他用户可以直接获取到该用户的想法。In practical applications, users can express their thoughts through comments, not through barrage. Therefore, in order to ensure better user interaction of the specified video, in this embodiment, when the user makes a comment on the specified video When commenting, the comment information can also be added to the specified video as a barrage. For example, when a user watches a specified video, he comments "this video is worth watching" in the comment area of the specified video, then after the user makes a comment, the comment "this video is worth watching" can be added as a barrage to a given video, so that other users can get the user's thoughts directly.
进一步地，添加单元330，适于根据指定视频播放时评论信息的生成时间点，将该评论信息作为弹幕添加到指定视频的相应的时间点处；或者，将评论信息作为弹幕内容添加到指定视频的与评论信息相匹配的内容所在的位置处。Further, the adding unit 330 is adapted to add the comment information as a bullet chat to the corresponding time point of the specified video according to the generation time point of the comment information when the specified video is played; or, add the comment information as the bullet chat content to the Specifies where the content of the video that matches the comment information is located.
用户在观看指定视频时，可能会实时对指定视频进行评论，为了作为弹幕的用户评论与指定视频的场景相对应，根据评论信息的生成时间或者内容，相对应的添加。例如，当用户观看到指定视频的第2分钟的时候，视频场景中的人物说了句名言，用户认为该名言非常经典，会在评论区发表评论信息“这句话太经典了”，那么为了使得该用户的评论信息与指定视频的场景相对应，根据该评论信息“这句话太经典了”生成的时间点是指定视频的第2分钟，那么就将该评论信息“这句话太经典了”作为弹幕添加到指定视频的第2分钟处。When a user watches a specified video, they may comment on the specified video in real time. In order to correspond to the scene of the specified video, user comments as bullet chatting are added correspondingly according to the generation time or content of the comment information. For example, when the user watches the second minute of the specified video, a character in the video scene utters a famous quote, and the user thinks the famous quote is very classic, and will post a comment message "This sentence is too classic" in the comment area, then for Make the user's comment information correspond to the scene of the specified video, and the time point generated according to the comment information "This sentence is too classic" is the second minute of the specified video, then the comment information "This sentence is too classic"了” is added as a barrage at the 2nd minute of the specified video.
或者，获取的用户评论信息可以作为弹幕的素材，当指定视频中的内容与评论信息相匹配的时候，可以将评论信息作为弹幕添加到指定视频对应的内容位置处，在这里不限于该评论信息的生成时间，只要内容相匹配就可以。例如，沿用上一个例子，用户在第2分钟发表了评论信息“这句话太经典了”，但是在对指定视频的内容进行识别时，识别到在第10分钟的内容中也出现了类似的经典名言，那么就可以将用户在第2分钟发表的评论信息“这句话太经典了”作为弹幕添加在指定视频的第10分钟处。Or, the obtained user comment information can be used as the material of the bullet chatting. When the content in the specified video matches the comment information, the comment information can be added as a bullet chatting to the content position corresponding to the specified video. It is not limited to this The generation time of comment information, as long as the content matches. For example, following the previous example, the user posted a comment message "This sentence is too classic" in the 2nd minute, but when identifying the content of the specified video, it was recognized that a similar sentence appeared in the 10th minute content Classic quotes, then the comment message "This sentence is too classic" posted by the user in the 2nd minute can be added as a barrage at the 10th minute of the specified video.
