關於IOS的視頻錄製 

昨天寫了一段程式關於視頻錄製的，老是庫找不到，提示錯誤。

  首先要加的是AVFoundtion.framework.

  接著提示

 

  "_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加進去！

接下來又是

Undefined symbols for architecture armv7:

  "_CMSampleBufferGetImageBuffer", referenced from:

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

  "_CMTimeMake", referenced from:

      -[AVCallController startVideoCapture] in AVCallController.o

 

這時候把CoreMedia.FrameWork 加進去
