在Python的`subprocess`模块中,`capture_output`参数是一个布尔值,用于指定是否捕获已执行子进程的标准输出和标准错误流。 当`capture_output`设置为`True`时,子进程的标准输出和标准错误流将被捕获并在`CompletedProcess`对象的`stdout`和`stderr`属性中分别返回为`bytes`对象。这允许你访问子进程产生的输出和错误信...

func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) { // 处理音视频数据 } } 在这个示例中,AVCaptureVideoDataOutput作为一个输出设备被添加到AVCaptureSession中,并设置了AVCaptureVideoDataOutputSampleBufferDelegate作为委托。然后,实现了委托...
在Python中,你可以使用`subprocess.run()`函数来运行一个外部命令,并获取其输出。你需要将`capture_output`参数设置为`True`,这样函数就会捕获标准输出和标准错误。然后,你可以从返回的`subprocess.CompletedProcess`对象中获取输出。 以下是一个示例³:
output The capture output object. sampleBuffer ACMSampleBufferobject containing the video frame data and additional information about the frame, such as its format and presentation time. connection The connection from which the video was received. ...
