转屏时能优化下吗？

iOS版本视频在横竖屏切换动画过程中会出现视频显示层直接 回到了原始状态，这种感觉太生硬了，并不是圆滑切换，这种感觉太不好了，能优化吗？还有请问钉钉群二维码过期了，是不允许进入群了吗？

No file, test, or entry point is named. Start by reproducing the iOS video-layer behavior during orientation changes and locating the orientation transition code; done means the video display transitions smoothly instead of snapping back, with the separate DingTalk group question clarified or excluded from scope.
