系统：iOS 10.3.3

微信：WeChat 6.5.14

在小程序中播放横屏视频：

<video id="video_8048" data-id="video_8048" src="https://pcmgrminiclubvideo-1252940971.file.myqcloud.com/group/src/10199/7838435773816479296.mp4" controls bindfullscreenchange="fullScreenChange" bindended="playEndEvt" objectFit="cover">video>

var videoContext = wx.createVideoContext('video_8048'); videoContext.requestFullScreen(); videoContext.play(); fullScreenChange: function (event) {    if (!event.detail.fullScreen) { // 退出全屏        var id = event.target.id;        var videoContext = wx.createVideoContext(id);        videoContext.pause();        videoContext.exitFullScreen();    } }, playEndEvt: function (event) {    var id = event.target.id;    var videoContext = wx.createVideoContext(id);    videoContext.pause();    videoContext.exitFullScreen(); },

调用

         videoContext.pause();

         videoContext.exitFullScreen();

播放后，待播放完毕后退出全屏，偶现小程序，微信都变成横屏布局模式，如下图：
