(EN) The invention relates to a screen projection picture self-adaption method and device in network teaching, electronic equipment and a storage medium. The method comprises the steps of: detecting and comparing the size of a network teaching screen projection source video with the display size of playing equipment, and generating a first judgment result; if the first preset condition is met, detecting an actual playing area of the network teaching screen projection source video picture according to a preset detection method, and generating a second judgment result; if the second preset conditionis met; and if yes, collecting the size of the actual playing area of the network teaching screen projection source video picture, and expanding the actual playing area of the network teaching screenprojection source video picture to the display size of playing equipment in an equal proportion, so as to adaptively adjust the display size of the playing equipment for playing according to the actual playing area of the network teaching screen projection source video picture. According to the invention, self-adaptive playing equipment is realized through detection of the screen projection picture in network teaching, the problem that the display content is too small when multiple pictures are used indiscriminately is solved, and the user experience is improved.
(ZH) 本公开是关于一种网络教学中投屏画面自适应的方法、装置、电子设备以及存储介质。其中，该方法包括：检测网络教学投屏源视频尺寸，并与播放设备显示尺寸对比，生成第一判断结果；若其满足第一预设条件，则根据预设检测方法检测网络教学投屏源视频画面实际播放区域，生成第二判断结果；若其满足第二预设条件，则采集网络教学投屏源视频画面实际播放区域的尺寸，并将所述网络教学投屏源视频画面实际播放区域等比例扩展至播放设备显示尺寸，以根据所述网络教学投屏源视频画面实际播放区域自适应调整播放设备显示尺寸进行播放。本公开通过网络教学中投屏画面的检测实现自适应播放设备，解决了多重画面套用时显示内容过小的问题，提高了用户体验。
