Android录制视频报错setVideoSize called in a invalid state 1 _android

学向勤中得，萤窗万卷书。这篇文章主要讲述Android录制视频报错setVideoSize called in a invalid state 1相关的知识，希望能为你提供帮助。
录制视频时想获取手机支持的录制视频的分辨率，使用代码如下：

List< Camera.Size> videoSize = camera.getParameters().getSupportedVideoSizes(); Iterator< Camera.Size> itos = videoSize.iterator(); while (itos.hasNext()) { Camera.Size curSize = itos.next(); int curSupporSize = curSize.width * curSize.height; int fixPictrueSize = setFixPictureWidth * setFixPictureHeight; if (curSupporSize > fixPictrueSize) { setFixPictureWidth = curSize.width; setFixPictureHeight = curSize.height; } } mediaRecorder.setVideoSize(setFixPictureWidth, setFixPictureHeight);

出现了两次错误，一次是录制视频时调用camera.getParameters()时报parameters is empty，这是由于在camera.unlock()之后调用了该函数，将其在unlock之前获取就ok了。
还有一个错误就是setVideoSize called in a invalid state 1，进入setVideoSize函数中可以发现抛出异常的条件说明

/** * Sets the width and height of the video to be captured.Must be called * after setVideoSource(). Call this after setOutFormat() but before * prepare(). * * @param width the width of the video to be captured * @param height the height of the video to be captured * @throws IllegalStateException if it is called after * prepare() or before setOutputFormat() */ public native void setVideoSize(int width, int height) throws IllegalStateException;

【Android录制视频报错setVideoSize called in a invalid state 1】IllegalStateException if it is called after prepare() or before setOutputFormat()表示如果setVideoSize在prepare() 之后或者setOutputFormat()之前调用的话就会出现该异常，即是说要求setVideoSize函数在prepare()之前以及setOutputFormat()之后调用。
查了下代码，发现我调用setVideoSize竟然是在setOutputFormat()之前，改到setOutputFormat()之后就ok了。
