本公开提供的技术方案带来的有益效果是：
在本实施例中，当检测到用户针对初始字幕信息的编辑操作时，可以确定视频展示区域以及编辑后的字幕展示区域，如果字幕展示区域不属于视频展示区域包括的子区域，则可以基于视频展示区域和字幕展示区域的区域信息，确定针对视频展示区域的各边长的第一扩展长度和第一扩展方向，这样基于第一扩展长度和第一扩展方向在应用程序展示页面对应的区域范围内对视频展示区域进行相应的扩展后，可以使得扩展后的视频展示 区域中包括字幕展示区域，这样视频发布后就可以在字幕展示区域中向用户展示完整的字幕信息，可见，本公开通过对视频展示区域进行扩展，使得扩展后的视频展示区域包括字幕展示区域，这样就可以展示完整的字幕信息，保证了字幕展示的完整性，可适应多样化的字幕信息的展示需求，适用于更多的场景，提升了用户体验。

请参照图1，本公开的方法具体可以由客户端执行，本公开包括：
步骤S101、检测到用户针对视频信息的初始字幕信息的编辑操作时，确定应用展示页面内的视频展示区域以及编辑后的字幕展示区域；
当客户端检测到用户针对视频信息的初始字幕信息的编辑操作时，可以自动触发对视频展示区域进行扩展的功能，客户端确定应用展示页面内视频展示区域(在本实施例中视频展示区域如无特殊说明均指扩展前的视频展示区域)以及用户编辑完成后的字幕展示区域，该视频展示区域是客户端自适应应用展示页面的大小生成的。
步骤S102、如果字幕展示区域不属于视频展示区域包括的子区域，则基于视频展示区域的区域信息和字幕展示区域的区域信息，确定针对视频展示区域的各边长的第一扩展长度以及第一扩展方向；
在本实施例中字幕展示区域(在本实施例中字幕展示区域如无特殊说明均指编辑后的字幕展示区域)不属于视频展示区域包括的任一子区域的一种可能的情况是，视频展示区域与字幕展示区域部分重合，且视频展示区域和字幕展示区域都在画布的区域范围内，画布的大小一般为应用展示页面的大小；另一种可能的情况是，视频展示区域与字幕展示区域为两个相互独立的区域，且视频展示区域和字幕展示区域都在画布的区域范围内。
客户端可以基于视频展示区域的区域信息和编辑后的字幕展示区域的区域信息，确定视频展示区域的各边长的第一扩展方向和第一扩展长度，视频展示区域的边长可以是视频展示区域的高和宽，第一扩展方向可以是将高向上或向下扩展，也可以是将宽向左或向右扩展。
步骤S103、在应用展示页面对应的区域范围内、基于第一扩展长度和第一扩展方向对视频展示区域进行相应的扩展，以使得扩展后的视频展示区域中包括字幕展示区域；
步骤S104、在字幕展示区域展示编辑后的字幕信息。
客户端可以在应用展示页面对应的区域范围(即画布对应的区域范围)内，基于各边长的第一扩展长度和第一扩展方向对视频展示区域的各边长在相应的扩展方向扩展相应的长度，从而完成视频展示区域的扩展，这样可以使得扩展后的视频展示区域中包括上述编辑后的字幕展示区域，即字幕展示区域属于扩展后的视频展示区域包括的子区域，从而视频发布后客户端可以在字幕展示区域展示编辑后的字幕信息，同时该字幕信息可以完整展示。
在本实施例中，当检测到用户针对初始字幕信息的编辑操作时，可以确定视频展示区域以及编辑后的字幕展示区域，如果字幕展示区域不属于视频展示区域包括的子区域，则可以基于视频展示区域和字幕展示区域的区域信息，确定针对视频展示区域的各边长的第一扩展长度和第一扩展方向，这样基于第一扩展长度和第一扩展方向在应用程序展示页面对应的区域范围内对视频展示区域进行相应的扩展后，可以使得扩展后的视频展示区域中包括字幕展示区域，这样视频发布后就可以在字幕展示区域中向用户展示完整的字幕信息，可见，本公开通过对视频展示区域进行扩展，使得扩展后的视频展示区域包括字幕展示区域，这样就可以展示完整的字幕信息，保证了字幕展示的完整性，可适应多样化的字幕信息的展示需求，适用于更多的场景，提升了用户体验。
根据本公开的实施例，编辑操作包括以下至少一项：
调整字幕的字体颜色、调整字幕的字体大小、调整字幕的文字内容、调整字幕展示区域的位置、调整字幕展示区域的大小、调整字幕展示区域 的形状。
在本实施中，用户针对字幕信息的编辑操作可以是调整字体的颜色；也可以是调整字体的大小，一般字体变大后字幕展示区域就会相应的扩大；还可以是对字幕的文字内容进行增加、删除以及修改等任意一项或多项的操作，增加、删除或修改文字内容均可能导致字幕展示区域的大小发生变化；还可以是调整字幕展示区域的位置，例如将位于视频展示区域内的字幕展示区域拖动到视频展示区域外；还可以是调整字幕展示区域的大小，例如扩大字幕展示区域，这种情况下也可能导致字幕展示区域的部分区域超出视频展示区域的区域范围；还可以是调整字幕展示区域的形状，例如改变字幕展示区域高和宽的长度。
根据本公开的实施例，任一展示区域的区域信息包括展示区域的各端点坐标；
基于视频展示区域的区域信息和字幕展示区域的区域信息，确定针对视频展示区域的各边长的第一扩展长度以及第一扩展方向，包括：
基于视频展示区域的各端点坐标和字幕展示区域的各端点坐标，确定视频展示区域和字幕展示区域的位置关系；
基于位置关系，确定针对视频展示区域的各边长的第一扩展方向；
对于视频展示区域的各边长，基于边长的第一扩展方向，从视频展示区域的端点坐标中确定第一目标端点坐标，同时从字幕展示区域的端点坐标中确定第二目标端点坐标，基于第一目标端点坐标和第二目标端点坐标，确定边长的第一扩展长度。
在本实施例中，视频展示区域(本实施例中指的是扩展前的视频展示区域)或字幕展示区域(本实施例中指的是编辑后的字幕展示区域)的区域信息可以是该视频展示区域或字幕展示区域的各端点坐标。
在应用展示页面对应的坐标系中，可以根据视频展示区域的各端点坐标以及字幕展示区域的各端点坐标确定视频展示区域和字幕展示区域的位置关系，从而基于该位置关系，可以确定视频展示区域的各边长的第一扩展方向，例如，如图2，在纵向维度上，字幕展示区域在视频展示区域的下方，则将可以将视频展示区域的高向下扩展。
对于视频展示区域的各边长，基于该边长的第一扩展方向可以从视频展示区域的端点坐标中确定第一目标端点坐标，同时从字幕展示区域的端点坐标中确定第二目标端点坐标，基于第一目标端点坐标和第二目标端点坐标确定该边长所在维度对应的坐标扩展距离，将该坐标扩展距离转化为应用展示页面上的第一扩展长度。例如，如图2，对于将视频展示区域的高向下扩展的场景，第一目标端点的坐标即为视频展示区域的各端点坐标中y轴上的最小坐标，第二目标端点的坐标即为字幕展示区域的各端点坐标中y轴上的最小坐标，计算第一目标端点坐标与第二目标端点坐标在y轴上的差值，该差值即为高的坐标扩展距离，将该坐标扩展距离转化为高的第一扩展长度，同样的，对于图2中视频展示区域还需要向右扩展，则对于视频展示区域的宽，第一目标端点的坐标即为视频展示区域的各端点坐标中x轴上的最大坐标，第二目标端点的坐标即为字幕展示区域的各端点坐标中x轴上的最大坐标，计算第一目标端点坐标与第二目标端点坐标在x轴上的差值，即为宽的坐标扩展距离，将该坐标扩展距离转化为宽的第一扩展长度。
在本实施中，还可以对各端点坐标进行归一化处理，将各端点坐标的x值和y值限制在0至1的范围内。
在本实施例中，可以将扩展视频展示区域得到的新增区域渲染为特定的背景色，例如用黑色填充新增区域。
根据本公开的实施例，在检测到用户针对初始字幕信息的编辑操作之前，该方法还包括：
获取待处理的视频数据，并基于视频数据得到音频信息；
将音频信息发送至服务器，以便于服务器对音频信息进行文字识别得到初始字幕信息；
接收服务器返回的初始字幕信息。
在本实施例中，客户端获取待处理的视频数据，该视频数据可以是用户上传的视频数据，也可以是从服务器的视频流中获取的视频数据，客户端可以将待处理的视频数据发送给服务器，服务器中预置有训练得到的文字识别模型，文字识别模型可以对视频数据中的音频信息进行文字识别， 从而识别得到初始字幕信息，还可以是客户端提取视频数据中的音频信息，客户端将音频信息发送给服务器，同样的服务器通过文字识别模型对音频数据进行文字识别得到初始字幕信息，客户端提取得到音频信息的方式可以减小服务器的数据处理压力，加快向客户端返回初始字幕信息的速度，减小了数据处理的时延。
客户端可以对待处理的视频数据进行处理从而得到视频信息，具体的处理过程是对视频数据进行编码和渲染等，从而可以在应用展示页面上展示视频信息和初始字幕信息，视频信息可以在应用展示页面的上述扩展前的视频展示区域中预览展示，初始字幕信息可以在应用展示页面中编辑前的字幕展示区域中预览展示，相当于向用户预览展示、视频发布后视频以及字幕的展示情况，可以理解的是，提供预览展示的视频以及字幕的展示情况也可以只提供视频和字幕的展示区域的相对位置关系，即两展示区域(扩展前的视频展示区域以及编辑前的字幕展示区域)的相关位置关系不变，实际发布后的两展示区域的大小与提供预览的两展示区域的大小可以不同。
在视频发布前，用户可以基于预览展示的视频信息和初始字幕信息，对初始字幕信息进行编辑，用户编辑完成后，客户端同样预览展示视频信息以及编辑后的初始字幕信息，同样的视频信息可以在上述应用展示页面的扩展前的视频展示区域中预览展示，编辑后的初始字幕信息可以在应用展示页面中编辑后的字幕展示区域中预览展示，或两展示区域(扩展前的视频展示区域以及编辑后的字幕展示区域)的相对位置关系不变，实际发布后的两展示区域的大小与提供预览的两展示区域的大小可以不同。这时编辑后的字幕展示区域有可能不属于视频展示区域包括的子区域，为了使得视频发布后，编辑后的初始字幕信息能够完全展示，需要触发本公开实施例描述的视频展示区域扩展功能。
根据本公开的实施例，在应用展示页面对应的区域范围内、基于第一扩展长度和第一扩展方向对视频展示区域进行相应的扩展之后，该方法还包括：
检测到视频发布指令时，基于编辑操作和初始字幕信息，确定编辑后 的字幕信息；
基于视频数据和编辑后的字幕信息进行视频合成，合成得到携带有编辑后的字幕信息的视频信息。
在接收到视频发布指令时，一般情况下，为防止用户对视频信息的相关属性有所更改，客户端需要重新获取视频数据，同样的将视频数据进行编码和渲染得到视频信息，将视频信息与编辑后的初始字幕信息进行合成，合成得到携带有编辑后的初始字幕信息的视频信息，当然，如上述在编辑前已经对视频数据处理得到视频信息，也可以直接基于该视频信息和编辑后的初始字幕信息进行合成，合成得到携带有编辑后的初始字幕信息的视频信息。
根据本公开的实施例，基于视频数据和编辑后的字幕信息进行视频合成，合成得到携带有编辑后的字幕信息的视频信息之后，该方法还包括：
在扩展前的视频展示区域中展示视频信息。
如上述对初始字幕信息的编辑操作触发客户端对视频展示区域进行了扩展，在本实施中，扩展前的视频展示区域是客户端自适应应用展示页面的大小生成的，为保证用户观看视频的体验，视频展示区域扩展后，视频信息的展示区域不会发生变化，即在扩展前的视频展示区域中展示视频信息，这样字幕展示区域的变化不会影响到视频展示区域的变化，避免了视频的变形等现象，保证了视频的展示效果。
下面，结合图3，对本公开实施例的应用场景进行描述。
待处理的视频数据处理后得到视频信息和初始字幕信息，预览展示视频信息和初始字幕信息，可以在上述扩展前的视频展示区域中预览展示视频信息，在编辑前的字幕展示区域中预览展示初始字幕信息；
编辑前，如图(编辑前的)字幕展示区域在(扩展前的)视频展示区域内部，这样视频发布后，(编辑前的)字幕展示区域中的初始字幕信息可以完整展示；
用户可以编辑初始字幕信息，例如调整字幕的字体大小、调整字幕的具体文字内容、将(编辑前的)字幕展示区域倾斜等，编辑后的字幕展示区域如图所示，同样的，可以在扩展前的视频展示区域中预览展示视频信 息，在编辑后的字幕展示区域中预览展示编辑后的初始字幕信息，但是这时的(编辑后的)字幕展示区域的部分区域在(扩展前的)视频展示区域的外部，视频发布后(扩展前的)视频展示区域外部展示的字幕无法向用户呈现；
为了使得视频发布后可以展示完整字幕，本公开中用户针对字幕的编辑操作会自动触发客户端进行视频展示区域扩展功能，如图中(扩展后的)视频展示区域包括(编辑后的)字幕展示区域，可以将新增的区域用黑色填充，这样检测到用户的视频发布指令后，客户端将视频信息和编辑后的初始字幕信息合成得到携带有编辑后的初始字幕信息的视频信息，并在应用展示页面上展示携带有编辑后的初始字幕信息的视频信息，具体的视频发布后最终的展示情况是：视频展示区域不变，即视频还是在编辑前的视频展示区域中展示，避免了视频展示区域的扩展导致视频的变形等情况的发生，字幕在编辑后的字幕展示区域中完全展示。
图4为本公开实施例提供的一种展示字幕信息的装置的结构示意图，该装置包括：
第一确定模块401，用于检测到用户针对视频信息的初始字幕信息的编辑操作时，确定应用展示页面内的视频展示区域以及编辑后的字幕展示区域；
