环境要求
Android 7.0以上Android Studio 官方开发者官网视频录制功能参考开源库PictureSelector的camerax库 //用到的Google 集成摄像头库const val camerax 1.4.2 const val appcompat 1.2.0val cameraEffectandroidx.camera:camera-effects:${Versions.camerax} //新版升级关键水印库val cameraHigh com.otaliastudios:cameraview:2.7.2val cameraCore androidx.camera:camera-core:${Versions.camerax}val camera2 androidx.camera:camera-camera2:${Versions.camerax}val cameraLife androidx.camera:camera-lifecycle:${Versions.camerax}val cameraView androidx.camera:camera-view:${Versions.camerax}val cameraTransient androidx.transition:transition:${Versions.appcompat}val cameraFutures androidx.concurrent:concurrent-futures:1.1.0代码实现 参考开源库PictureSelector的camerax库如果代码缺失某个类那么去PictureSelector库拷贝类使用即可。 最新的Camerax修改buildCase的逻辑改用Recording类VideoCapture也不支持设置帧率、比特率使用分辨率选项调整视频的清晰度和文件大小即 setQualitySelector(QualitySelector.from(Quality.LOWEST)) 核心变动 bindCameraVideoUseCases()编码参考官网OverlayEffect写法。 // CustomCameraView.kt

总结 这个录制视频水印如此简单其实是借助官方camerax库升级版的API实现的也就OverlayEffect的绘制我这是实现铺满斜着的多行文本水印。之前camerax版本val camerax “1.1.0-beta02” 就不支持要升到v1.4.2随着升级版本整个camerax用法上有比较大差别引入了新的Recording类等我是根据Android开发者官网示例修改的。
