关于IOS的视频录制

  昨天写了一段程序关于视频录制的，老是库找不到，提示错误。

  首先要加的是AVFoundtion.framework.

  接着提示

  "_CVPixelBufferGetPixelFormatType", referenced from:

      -[AVCallController captureOutput:didOutputSampleBuffer:fromConnection:] in AVCallController.o

  "_CVPixelBufferUnlockBaseAddress", referenced from:

      -[AVCallController captureOutput:didOutputSampleBuffer:fromConnection:] in AVCallController.o

  "_CVPixelBufferGetHeight", referenced from:

      -[AVCallController captureOutput:didOutputSampleBuffer:fromConnection:] in AVCallController.o

  "_CVPixelBufferGetDataSize", referenced from:

      -[AVCallController captureOutput:didOutputSampleBuffer:fromConnection:] in AVCallController.o

  "_kCVPixelBufferHeightKey", referenced from:

      -[AVCallController startVideoCapture] in AVCallController.o

  "_CVPixelBufferGetBaseAddress", referenced from:

      -[AVCallController captureOutput:didOutputSampleBuffer:fromConnection:] in AVCallController.o

  "_CVPixelBufferLockBaseAddress", referenced from:

      -[AVCallController captureOutput:didOutputSampleBuffer:fromConnection:] in AVCallController.o

  "_kCVPixelBufferWidthKey", referenced from:

      -[AVCallController startVideoCapture] in AVCallController.o

  "_CVPixelBufferGetWidth", referenced from:

      -[AVCallController captureOutput:didOutputSampleBuffer:fromConnection:] in AVCallController.o

把coreVideo.FrameWork加进去！

接下来又是

Undefined symbols for architecture armv7:

  "_CMSampleBufferGetImageBuffer", referenced from:

      -[AVCallController captureOutput:didOutputSampleBuffer:fromConnection:] in AVCallController.o

  "_CMTimeMake", referenced from:

      -[AVCallController startVideoCapture] in AVCallController.o

这时候把CoreMedia.FrameWork 加进去
