你好，现在被一个问题卡死了，就是在推流时设置的是横屏，但是推流过程中切换到竖屏时尺寸发生了变化，怎么能够在推流过程中去修改推流大小呢？

推流改变宽高有两种情况：

分辨率不变，仅对 surfaceTexture 中的画面进行旋转，所以旋转后会看到横屏视频转为竖屏上下有黑边，视频画面内容变小，但原始帧的分辨率没变
分辨率或者别的 meta-data 已经改变，这就得重新再次将编码器的参数再次初始化一次，拉流的解码器对整个视频的 meta-data 重新再次拉取

一般来说推流过程中是不推荐第二种强行改变视频宽高的，因为拉流那边的播放器兼容性不一，有些是不支持过程中再次解析 meta-data 的
