问题核心 #

创建捕获会话时添加recorderSurface会触发"Unsupported set of inputs/outputs provided"错误，移除该Surface则会话可正常创建，但无法进行视频录制，此问题仅存在于Redmi Note 11 Pro 5G机型。

解决方案建议 #

1. 修复MediaRecorder资源释放时机
   当前代码中createRecordRequest内调用prepare()后立刻执行release()，会导致recorderSurface关联的MediaRecorder资源被提前释放，Surface处于无效状态。应将release()移至录制完成后的销毁逻辑中。

2. 调整Surface组合与编码格式

   • 尝试将视频编码格式从HEVC（MediaRecorder.VideoEncoder.HEVC）改为H.264（MediaRecorder.VideoEncoder.H264），部分机型对HEVC的多Surface组合支持有限。
   • 检查相机支持的Stream组合：通过CameraCharacteristics.SCALER_STREAM_CONFIGURATION_MAP获取相机允许的输入输出组合，确认同时添加两个YUV ImageReader和录制Surface是否在支持列表中。若不支持，可暂时移除captureReader验证是否能正常创建会话，再考虑后续优化。

3. 动态添加录制Surface
   不在创建CaptureSession时添加recorderSurface，而是在需要开始录制时，通过captureSession.addOutputTarget(recorderSurface)动态添加；录制结束后调用captureSession.removeOutputTarget(recorderSurface)移除，避免启动时的组合不兼容问题。
