我想获得1920 x 1080 jpeg onPreviewFrame。
onPreviewFrame上框架的大小取决于Camera.setPictureSize / Camera.setPreviewSize（如果我错了，请更正我）
目前，当我使用默认摄像机拍摄1080p视频时，我能够获得分辨率为1920 x 1080的视频。因此，我认为我应该可以从onPreviewFrame获得1920 x 1080帧。
然而，当我要求我的相机打印所有支持的PictureSize和支持的PreviewSize时，它显示1280 x 720作为最大尺寸。
因为相机说最大尺寸为1280 x 720，所以我无法以1920 x 1080拍摄帧。
我在这里遗漏了一些阻止我获得1920 x 1080帧的东西，或者是否有任何可以让我设置的setPictureSize和PreviewSize大于SupportedPictureSize和SupportedPreviewSize
以下是nexus 4后置摄像头支持的预览和图片尺寸列表的日志。
感谢阅读，并感谢任何帮助或建议。
