创建录像输出流。
通过CameraOutputCapability类中的videoProfiles,可获取当前设备支持的录像输出流。然后,定义创建录像的参数,通过createVideoOutput方法创建录像输出流。
通过CameraOutputCapability类中的videoProfiles,可获取当前设备支持的录像输出流。然后,定义创建录像的参数,通过createVideoOutput方法创建录像输出流。
**注**
:预览流与录像输出流的分辨率的宽高比要保持一致,如示例代码中宽高比为640:480 = 4:3,则需要预览流中的分辨率的宽高比也为4:3,如分辨率选择640:480,或960:720,或1440:1080,以此类推
