请参考图1，其示出了根据本公开的交互方法的一个实施例的流程。该交互方法应用于终端设备。如图1所示该交互方法，包括以下步骤：
步骤101，响应于检测到预定义的尺寸变换操作，基于目标视频的当前尺寸是否是预设锚点尺寸，确定目标视频的目标变换信息。
在本实施例中，交互方法的第一执行主体(例如终端设备)可以响应于检测到预定义的尺寸变换操作，基于目标视频的当前尺寸是否是预设锚点尺寸，确定目标视频的目标变换信息。
在本实施例中，上述预定义的尺寸变换操作，可以是预先定义的操作，该预先定义的操作可以用于对图像进行尺寸变换。预定义变换操作的具体方式，可以根据实际应用场景设置，在此不 做限定。
在本实施例中，上述预定义变换操作的实施位置可以是在视频播放区域中，也可以是在视频播放区域之外的区域；还可以是通过语音控制实施的。
作为示例，上述预定义的尺寸变换操作可以包括二指操作，二指操作可以形象地理解为通过两个手指进行操作；当然，具体操作的时候，用户可以用任何部位模拟二指的效果，进行二指操作。例如，两个手指之间的距离拉大，可以作为放大操作；两个手指之间的距离减小，可以作为缩小操作。另外，两个手指之间的距离不变，两个手指一起移动，可以作为平移操作。
在一些应用场景中，一次尺寸变换操作，可以是用户从开始操作到释放操作的过程。可以理解，在一次尺寸变换操作中，可能实施一种或者多种具体的变换操作。例如，在一次尺寸变换操作中，可能包括放大操作和缩小操作。
作为示例，用户开始尺寸变换操作的过程中，可以先放大目标视频，在不释放尺寸变换操作的过程中，再缩小目标视频；这种情况下，上述尺寸变换操作可以包括放大操作类型和缩小操作类型。例如可以根据在当前视频画面上首先识别到的操作类型，以及当前画面尺寸是否是预设锚点尺寸，确定目标变换信息。比如，在一些实施例中，当前视频画面是原始视频尺寸、且在当前视频画面上识别到了放大操作，无论该操作是否已释放，都可以将当前视频画面调整为满屏尺寸。
在一些实施例中，对于尺寸变换操作的操作类型的确定，可以根据用户开始操作的操作位置与释放操作的操作位置之间的矢量确定。换句话说，开始操作到释放操作的过程中用户的操作轨迹，可以不作为确定操作类型的依据。
作为示例，用户可以对目标视频进行尺寸变换。目标视频的当前尺寸为A，用户可以先放大再缩小至B，B小于A。在用户先放大再缩小的过程中，目标视频的画面可以跟随用户的操作先放大再缩小。当用户释放这次操作的时候，可以确定此次操作的操 作类型为缩小操作。在这里，目标视频为视频播放区域中播放的视频。
在这里，上述目标视频的当前尺寸，可以是尺寸变换操作开始的时候目标视频的尺寸。
在本实施例中，尺寸变换可以包括将视频尺寸变大。
在本实施例中，尺寸变换可以包括将视频尺寸缩小。
在一些实施例中，平移可以包括将视频画面在视频播放区域进行移动。在这里，预设锚点尺寸可以是预设的常用尺寸。需要说明的，视频的尺寸可以是连续变化的，利用预设锚点尺寸这种表述，可以形象地表示在连续变化的尺寸中的一些尺寸，可以作为定点，来表示常用的视频尺寸。
在一些实施例中，预设锚点尺寸可以包括以下至少一项但不限于：原始图像尺寸、满屏图像尺寸。
在这里，上述原始图像尺寸，可以是目标视频中的视频帧显示到终端设备的原始尺寸。
在这里，上述满屏图像尺寸，可以是上述目标视频在终端设备上全屏播放状态下的尺寸。其中，全屏播放状态，也可以称为满屏播放状态，通常是指大于原始图像尺寸的、能在预设显示区域内最大化显示的状态，例如，可以是将视频画面充满视频播放区域的状态。
在这里，目标视频的目标变换信息，可以是用于对目标视频进行变换的信息。作为示例，目标变换信息可以指示变换方式，对应自由缩放模式的目标变换信息，可以理解为根据用户操作的比例变换当前视频尺寸。作为示例，目标变换信息可以包括但是不限于以下至少一项：目标变换比例、目标变换尺寸。
在这里，目标变换比例，可以指示对当前尺寸进行变换的比例，例如，变换至当前尺寸的二倍。
在这里，目标变换尺寸，可以指示期望将目标视频变换至的尺寸。
需要说明的是，本申请中的尺寸，可以是绝对尺寸，也可以 是相对尺寸。在一些应用场景中，尺寸(例如锚点尺寸、目标视频尺寸)也可能根据机型的不同而不同。作为示例，如果将原始图像的尺寸作为分子，那其它尺寸与原始图像的尺寸的比值(即相对尺寸)，也可以称为本申请中的尺寸。
步骤102，基于目标变换信息，对目标视频进行变换，以及播放变换后的目标视频。
在本实施例中，上述执行主体可以基于所述目标变换信息，对所述目标视频进行变换，以及播放变换后的目标视频。
在这里，可以在视频播放区域中，播放变换后的目标视频。
在一些应用场景中，视频播放区域的尺寸可能发生变换。例如，视频播放区域的尺寸，可以是满屏尺寸，也可以是四分之三的屏幕尺寸。换句话说，视频播放区域的尺寸，可能在至少两种尺寸之间切换。
作为示例，请参考图2，视频播放区域201为矩形，目标视频画面202也为矩形。可以理解，我们可以将图2中矩形沿着横向的边，称为矩形的长；将矩形沿着纵向的边，称为矩形的宽。目标视频画面可以理解为显示在视频播放区域中的目标视频。
需要说明的是，图2中为了方便示意，将目标视频画面202的图像设置为远小于视频播放区域201的图像。
在实际应用场景中，如果目标视频的长小于视频播放区域的长，并且目标视频的宽小于视频播放区域的宽，可以将目标视频画面的尺寸设置为目标视频的尺寸一致。
在实际应用场景中，如果目标视频的长大于视频播放区域的长，或者目标视频的宽大于视频播放区域的宽，可以将目标视频画面的尺寸设置为视频播放区域的尺寸一致。换句话说，目标视频画面是目标视频的视频帧的一部分。
需要说明的是，本实施例提供的交互方法，可以在检测到尺寸变换操作的时候，参考目标视频的当前尺寸是否是预设锚点尺寸，确定目标视频的目标变换信息。由此，可以在尺寸变换操作中，兼容用户对于预设锚点尺寸缩放需求，将目标视频快速变换 到用户常用的尺寸，减少用户操作，提高交互效率。并且，使得视频播放区域中的目标视频画面可以满足用户获取信息的需要，提高用户的信息获取效率。
在一些实施例中，上述方法可以包括：响应于检测到在视频播放区域的预定义的平移操作，以及响应于确定目标视频的当前尺寸大于视频播放区域的尺寸，在所述视频播放区域中移动目标视频。
在这里，上述预定义的平移操作可以用于对目标视频进行平移。上述预定义的平移操作的具体实施方式，可以根据实际应用场景设置，在此不做限定。
作为示例，上述预定义的平移操作可以是拖动操作，实施拖动操作时人体与屏幕的触发点的个数，可以不做限定。作为示例，上述预定义的平移操作可以是单指拖动操作，可以是双指拖动操作，还可以是三指拖动操作。在这里，上述目标视频的当前尺寸大于视频播放区域的尺寸，可以理解为至少在一个方向上，目标视频的边长大于视频播放区域的边长。请参考图2，可以是目标视频的长大于视频播放区域的长，或者，可以是目标视频的宽大于视频播放区域的宽。
需要说明的是，通过预定义的平移操作，可以实现目标视频在视频播放区域进行移动，由此，用户可以将期望观看的部分移动到便于观看的位置，提高用户的信息获取效率。
作为示例，用户在观看美妆类视频时，可能会关注博主使用的美妆产品，当视频没有给到产品特写镜头时会较难看清。通过本申请提供的尺寸变换操作和/或平移操作，可以将产品处的视频画面放大，用户还可以将产品处的视频画面移动到视频播放区域的中间位置，从而可以清楚地查看美妆产品信息。
在一些实施例中，基于目标视频的当前尺寸是否是预设锚点尺寸，确定目标视频的目标变换信息，包括：基于所述尺寸变换操作的操作类型和所述预设锚点尺寸，确定对应的目标变换信息。
在一些实施例中，所述基于所述尺寸变换操作的操作类型和所述预设锚点尺寸，确定对应的目标变换信息，包括：响应于所述操作类型和所述预设锚点尺寸满足第一预设关系，采用第一目标变换信息，其中，第一目标变换信息指示将目标视频的尺寸在不同的预设锚点尺寸之间切换；响应于所述操作类型和所述预设锚点尺寸满足第二预设关系，采用第二目标变换信息，其中，第二目标变换信息对应自由缩放模式。
在一些实施例中，所述第一预设关系指示所述操作类型、所述目标视频的当前尺寸、以及预设锚点尺寸之间，满足预设的第一对应关系、或者不满足预设的第二对应关系。
在一些实施例中，第二预设关系指示所述操作类型、所述目标视频的当前尺寸、以及预设锚点尺寸之间，不满足预设的第一对应关系、或者满足预设的第二对应关系。
在一些实施例中，所述第一预设关系包括：目标视频的当前尺寸是原始图像尺寸、且所述操作类型是放大操作，所述目标变换信息包括将所述目标视频变换到满屏图像尺寸；和/或，目标视频的当前尺寸是满屏图像尺寸、且所述操作类型是缩小操作，所述目标变换信息包括将所述目标视频变换到原始图像尺寸。
在一些实施例中，所述第二预设关系包括：目标视频的当前尺寸是原始图像尺寸、且所述操作类型是缩小操作，所述目标变换信息包括根据操作信息将所述目标视频进行自由缩放；和/或，目标视频的当前尺寸是满屏图像尺寸、且所述操作类型是放大操作，所述目标变换信息包括根据操作信息将所述目标视频进行自由缩放。
在这里，第一目标变换信息指示将目标视频的尺寸在不同的预设锚点尺寸之间切换。
在这里，第二目标变换信息对应自由缩放模式。在自由缩放模式下，可根据用户操作对目标视频的尺寸进行连续性的放大或缩小，例如，在用户操作的两个触点之间的距离越来越大时，逐渐将目标视频的尺寸放大，或者，在用户操作的两个触点之间的距离越来越小时，逐渐将目标视频的尺寸缩小。
在一些实施例中，上述步骤101，可以包括：响应于确定当前尺寸是预设锚点尺寸，以及响应于所述尺寸变换操作的操作类型与预设锚点尺寸对应，将所述预设锚点尺寸对应的预设变换信息，确定为所述目标变换信息。
在这里，尺寸变换操作的操作类型可以包括以下至少一项：缩小操作、放大操作。
在这里，每个预设锚点尺寸，均有相对应的预设变换信息，也具有相对应的操作类型。
在一些应用场景中，如果响应于确定当前尺寸是预设锚点尺寸，以及响应于所述尺寸变换操作的操作类型与预设锚点尺寸不对应，可以进入自由缩放模式。
在这里，预设变换信息可以根据实际应用场景设置，在此不做限定。预设变换信息的，可以是预设的变换比例，也可以是预设的尺寸。
需要说明的是，通过设置预设锚点尺寸与操作类型的对应关系，以及设置预设锚点尺寸与预设变换信息的对应的关系，可以在目标视频处于锚点尺寸的情况下，通过一次对应的操作，即可实现视频画面快速变换至常用的尺寸，例如其它预设锚点尺寸，避免了用户多次操作才能变换至期望的尺寸。由此，减少了用户操作，进而减少因用户操作而耗费的计算资源和显示资源。
在一些实施例中，所述尺寸变换操作包括放大操作，所述预 设锚点尺寸包括原始图像尺寸，与原始图像尺寸对应的预设变换信息指示满屏图像尺寸，与原始图像尺寸对应的操作类型为放大操作。
在这里，与原始图像尺寸对应的预设变换信息指示满屏图像尺寸，可以理解为：与原始图像尺寸对应的预设变换信息，可以指示将原始图像尺寸变换到满屏图像尺寸的变换信息。
相应的，响应于确定当前尺寸是预设锚点尺寸，以及响应于所述尺寸变换操作的操作类型与预设锚点尺寸对应，将所述预设锚点尺寸对应的预设变换信息，确定为所述目标变换信息，可以包括：响应于确定当前尺寸是所述原始图像尺寸，以及响应于检测到在视频播放区域的放大操作，将指示满屏图像尺寸的预设变换信息确定为目标变换信息。
需要说明的是，在目标视频处于原始图像尺寸的时候，实施放大操作，可以将目标视频调整到满屏图像尺寸。由此，可以减少用户操作次数，减少因用户操作而耗费的计算资源和显示资源。
在一些实施例中，所述尺寸变换操作包括缩小操作，所述预设锚点尺寸包括满屏图像尺寸，与满屏图像尺寸对应的预设变换信息指示原始图像尺寸，与满屏图像尺寸对应的操作类型为缩小类型。
在这里，与满屏图像尺寸对应的预设变换信息指示原始图像尺寸，可以理解为，与满屏图像尺寸对应的预设变换信息，可以指示将满屏图像尺寸变换到原始图像尺寸的变换信息。
相应的，响应于确定当前尺寸是预设锚点尺寸，以及响应于所述尺寸变换操作的操作类型与预设锚点尺寸对应，将所述预设锚点尺寸对应的预设变换信息，确定为所述目标变换信息，可以包括：响应于确定当前尺寸是满屏图像尺寸，以及响应于检测到在视频播放区域的缩小操作，将所述指示原始图像尺寸的预设变换信息确定为目标变换信息。
需要说明的是，在目标视频处于满屏图像尺寸的时候，实施缩小操作，可以将目标视频调整到原始图像尺寸。由此，可以减 少用户操作次数，减少因用户操作而耗费的计算资源和显示资源。
在一些实施例中，请参考图3，其示出上述步骤101的一种可选的实现方式。图3中示出的流程可以包括步骤1011和步骤1012。
步骤1011，响应于检测到在视频播放区域的尺寸变换操作，以及响应于预设的自由缩放条件满足，进入自由缩放模式。
步骤1012，响应于确定进入自由缩放模式，根据所述尺寸变换操作的变换信息和目标视频的当前尺寸，确定所述目标变换信息。
换句话说，自由缩放模式下，可以根据所述尺寸变换操作的变换信息和所述目标视频的当前尺寸，确定所述目标变换信息。
在一些应用场景中，自由缩放模式下，目标视频在放大的过程中，可能视频图像被放大后的尺寸大于屏幕尺寸，此时，屏幕中仅能显示被放大后的视频图像尺寸的一部分，可以通过拖动视频图像等操作来显示放大后的视频图像的其他部分。
在一些实施例中，上述所述自由缩放条件可以包括以下至少一项但不限于：目标视频不是预设锚点尺寸，确定所述尺寸变换操作的操作类型与所述预设锚点尺寸不对应。
作为示例，在目标视频为原始图像尺寸的基础上，缩小画面可以进行自由缩放模式，即可以自由放大或者缩小视频画面。
作为示例，在目标视频为满屏图像尺寸的基础上，放大画面可以进入自由缩放模式，可以自由放大或者缩小视频画面。
需要说明的是，通过设置上述自由缩放条件，可以贴合用户使用场景，满足用户在自由缩放和锚点尺寸变换之间的切换需求，进而可以减少用户用于尺寸变换操作的操作次数和操作时间，提高操作效率。
在一些实施例中，所述自由缩放条件包括：目标视频的当前尺寸是预设锚点尺寸，并且，尺寸变换操作释放时目标视频的实时尺寸与所述当前尺寸的比例所指示的操作类型，与预设锚点尺寸对应。
在一些应用场景中，随着尺寸变换操作的进行，执行主体可 以实时确定目标视频的实时尺寸。
在一些实施例中，在所述尺寸变换操作释放前，基于尺寸变换操作指示的变换信息，实时变换目标视频的尺寸。换句话说，随着尺寸变换操作的进行，屏幕上显示的目标视频可以跟随尺寸变换此操作的指示，进行放大或者缩小。
需要说明的是，根据用户的尺寸变换操作，实时显示尺寸变换效果，可以及时向用户展示尺寸变换的进度，便于用户根据实施缩放至的效果，继续或者终止尺寸变换操作。
在一些应用场景中，可以将实时尺寸作为判断用户操作类型的依据。
在这里，如果上述尺寸变换操作释放时目标视频的实时尺寸与所述当前尺寸的比例，大于1，可以指示放大操作类型。如果尺寸变换操作释放时目标视频的实时尺寸与所述当前尺寸的比例，小于1，可以指示缩小操作类型。
需要说明的是，将操作释放时的实时尺寸作为判断用户操作类型的依据，可以提高确定操作类型的准确性，进而提高变换的准确性。具体来说，用户在实时观看视频，并且根据实时画面确定是否释放尺寸变换操作，因此，用户释放尺寸变换操作时目标视频的实时尺寸，可以较为准确地体现用户对于尺寸变换程度的期望。
在一些实施例中，一方面，通过参考目标视频的当前尺寸是否是预设锚点尺寸，确定目标视频的目标变换信息，来兼容用户常用的变换操作，满足大部分用户的操作需求，另一方面，通过设置自由缩放模式的触发条件，在特定条件下(例如在满屏状态下接收到放大操作，或者在原始图像尺寸条件下接收到缩小操作，其中，放大操作和缩小操作可以是实时的操作结果，也可以是操作释放时的操作结果)触发自由缩放模式，能够提供更精细的缩放处理，满足部分用户的进一步需求，上述两方面的融合，可以满足海量用户的不同操作场景、最大化操作效率和体验。
在一些实施例中，上述方法还可以包括：基于对目标视频进 行的缩放方式，展示对应的提示信息，其中，所述提示信息用于提示缩放方式。
在这里，上述提示信息的展示方式和内容，可以根据实际应用场景设置，在此不做限定。
作为示例，可以利用横幅(toast)的方式，展示提示信息。
作为示例，缩放方式可以指示调整至满屏图像尺寸，对应的提示信息可以是“已切换至满屏”。
作为示例，缩放方式可以指示自由缩放模式，对应的提示信息可以是“已进入自由缩放模式”
作为示例，缩放方式可以指示调整至原始图像尺寸，对应的提示信息可以是“已恢复原始大小”。
在一些实施例中，所述基于对目标视频进行的缩放方式，展示对应的提示信息，包括：响应于将目标视频调整至满屏图像尺寸，展示第一提示信息，其中，所述第一提示信息用于指示目标视频为满屏播放状态。
在一些实施例中，所述基于对目标视频进行的缩放方式，展示对应的提示信息，包括：响应于将目标视频调整至原始图像尺寸，展示第二提示信息，其中，所述第二提示信息用于指示目标视频为原始尺寸播放状态。
在一些实施例中，所述基于对目标视频进行的缩放方式，展示对应的提示信息，包括：响应于确定进入自由缩放模式，展示第三提示信息，其中，所述第三提示信息用于指示目标视频能够基于尺寸变换操作自由缩放。
在一些实施例中，所述方法还包括：响应于确定变换后的目标视频不是原始图像尺寸，展示还原控件，其中，所述还原控件用于将目标视频变换至原始图像尺寸。
换句话说，如果视频画面是非原始比例，可以展示标示有“还原屏幕”字样的按钮，点击“还原屏幕”的按钮后，可以切回原始图像尺寸的视频画面。
需要说明的是，通过还原控件的设置，可以使得用户便捷地 切换原始图像画面，减少用户期望回到原始图像画面时的操作，即可以提高交互效率。
在一些实施例中，上述方法还可以包括：响应于尺寸变换操作和/或平移操作结束，检测目标视频是否被移出视频播放区域；响应于确定被移出，对视频播放区域中的视频画面进行校正，得到与视频播放区域尺寸匹配的目标视频画面。
在这里，是否移出视频播放区域的判断，可以根据实际应用场景，设置具体的判断条件进行判断。在一些实施例中，如果在一方向上，视频播放区域中没有画面，但是沿着该方向目标视频还具有没有显示的图像，那么这种情况可以理解为视频被移出了视频播放区域。
在这里，对视频画面进行校正，可以包括将目标视频进行平移等操作，将目标视频拉回到视频播放区域。
作为示例，如果目标视频的画面被移出视频播放区域，可以将目标视频拉回到视频播放区域。
需要说明的是，通过设置校正环节，可以减少目标视频被移出视频播放区域的情况发生，提高信息展示效率。
图4实施例的引入，可以解决进一步的技术问题，即视频尺寸变换操作可能造成视频播放画面布局混乱的问题。
需要说明的是，图4实施例提供的方法，可以应用于本申请所涉及的任何对目标视频的变换场景当中。图4实施例提供的方法，可以应用于尺寸变换场景和/或平移场景当中。应用到尺寸变换场中，可以包括应用到自由缩放场景当中，也可以应用到基于预设变换信息进行尺寸变换的场景当中。
请参考图4，其示出了根据本公开的交互方法的一个实施例的流程。在图4所示流程中，可以包括：
步骤401，将第一图层封装到第二图层。
在本实施例中，交互方法的第一执行主体(例如终端设备)可以将第一图层封装到第二图层。
在这里，所获取的目标视频所在的图层为第一图层。
通常，终端上的播放器可以从本地或者其它电子设备，获取目标视频。并且播放器解析出的目标视频绘制于图层上，此图层可以供屏幕进行显示。在一些应用场景中，播放器还可以包括播放逻辑信息，来控制视频的播放，例如控制切换视频、控制播放进度等。
在这里，可以将播放器对应的图层记为第一图层。在这里，播放器对应的图层，可以理解为播放器解析出的视频可以绘制到该图层上。
在这里，第二图层中的目标视频与第一图层中的目标视频播放进度一致。
在这里，第二图层可以理解为第一图层外封装的一个新图层。第二图层的变换不会影响播放器的播放逻辑。并且，第二图层的播放进度与第一图层的播放进度一致。换句话说，可以理解为将第一图层上的目标视频，再绘制到第二图层上。
在一些应用场景中，第一图层中图层的数量可以是一个，也可以是至少两个。如果是至少两个，可以将各个图层的显示内容都可以绘制到第二图层。
在这里，所述第二图层中的目标视频用于根据尺寸变换操作和/或平移操作进行变换。换句话说，在第一图层外封装了第二图层后，屏幕显示的图像，可以从第二图层中获取。
需要说明的是，步骤401提供的方式，可以应用于尺寸变换场景和/或平移场景当中。
在一些实施例中，上述第一执行主体可以通过以下方式，对第二图层中的目标视频进行变换：根据尺寸变换操作和/或平移操作的操作位置信息，确定变换系数，其中，所述变换系数包括以下至少一项：尺寸变换信息、平移系数；根据变换系数，对第二图层中的目标视频进行变换。
步骤402，根据尺寸变换操作和/或平移操作的操作位置信息，确定变换系数。
在这里，在这里，所述变换系数包括以下至少一项：尺寸变 换信息、平移系数。
在这里，上述预定义变换操作可以包括但是不限于以下至少一项：尺寸变换操作、平移操作。
在这里，用户可以触摸屏幕，终端将触摸信号转换为逻辑坐标点。然后终端可以计算手指滑动时坐标点距离的变化，从而计算出位移。然后根据位移，确定变换信息和/或平移系数。
步骤403，根据变换系数，对第二图层中的目标视频进行变换。
需要说明的是，图4对应的实施例提供的交互方法，可以在播放器对应的图层之外，封装新的图层；并且在新的图层上进行变换。由此，可以将视频播放与视频变换进行隔离，保证视频变换不会影响播放器对于目标视频的处理(包括播放、变换等)。从而，可以保证视频播放和视频变换同时进行，提高交互效率和信息展示效率，同时提高用户的信息获取效率。
在一些实施例中，所述方法还可以包括：从第二图层的目标视频中，获取与视频播放区域匹配的目标视频画面；在视频播放区域中，播放与视频播放区域匹配的目标视频画面。
在这里，可以将第二图层的预设区域与视频播放区域对应。该预设区域中的图像是需要显示到视频播放区域的。
作为示例，对于平移操作，可以将第二图层上的图像进行坐标的平移变换，可以理解，此时预设区域中的图像将会发生改变。
作为示例，对于尺寸变换操作，可以对第二图层上的图像进行变换，可以理解，此时预设区域中的图像将会发生改变。
在这里，第二图层中的图像无论是否改变，在视频播放区域显示的图像，均可以是从上述预设区域获取的。
在一些应用场景中，视频播放区域的尺寸可以小于目标视频的尺寸，由此视频播放区域不能显示目标视频的完整画面。这种情况下，可以将获取与视频播放区域匹配的目标视频的画面，作为目标视频画面显示在视频播放区域中。
在这里，与视频播放区域匹配的判断，可以根据实际应用场景设置匹配判断条件进行判断。
作为示例，如果目标视频的长小于视频播放区域的长，并且目标视频的宽小于视频播放区域的宽，可以将目标视频的完整画面作为与视频播放区域匹配的目标视频画面。
作为示例，如果用户在满屏基础上继续放大，则显示在屏幕上的画面，是完整视频画面的一部分。因此，需要获取与视频播放区域匹配的部分视频画面，作为目标视频画面。目标视频画面的长可以与视频播放区域的长一致，目标视频画面的宽可以与视频播放区域的宽一致。
需要说明的是，通过从第二图层中获取目标视频画面，可以在不改变播放器播放逻辑的情况下，获取与视频播放区域匹配的视频画面，对于用户来说，播放和对视频的变换可以同时进行，由此，可以提高信息展示效率，同时提高用户的信息获取效率。
请继续参考图5，其示出了根据本公开的视频变换方法的一个实施例的流程。该交互方法应用于终端设备，如图所示该视频变换方法，包括以下步骤：
步骤501，将第一图层封装到第二图层。
在本实施例中，交互方法的第二执行主体(例如第一电子设备)可以向支持无线网络的数据转发设备，发送数据转发请求。
在这里，第二图层中的目标视频与第一图层中的目标视频播放进度一致，播放器对应的图层为第一图层。
步骤502，根据预定义变换操作，对第二图层中的目标视频进行变换。
在一些实施例中，上述步骤501，可以包括：根据所述预定义变换操作的操作位置信息，确定变换系数，其中，所述变换系数包括以下至少一项：尺寸变换信息、平移系数；根据尺寸变换信息和平移系数，对第二图层中的目标视频进行变换。
在一些实施例中，上述方法还可以包括：从第二图层的目标视频中，获取与视频播放区域匹配的目标视频画面；播放与视频播放区域匹配的目标视频画面。
需要说明的是，图5对应的实施例所提供的交互方法中，各 个步骤的实现细节和技术效果，可以参考本申请中相关部分的说明，在此不再赘述。
进一步参考图6，作为对上述各图所示方法的实现，本公开提供了一种交互装置的一个实施例，该装置实施例与图1所示的方法实施例相对应，该装置具体可以应用于各种电子设备中。
