我尝试使用GPUImage库录制视频。录制的剪辑以黑框结束。我知道这是由 audioEncodingTarget 引起的,这是一项非常昂贵的操作。这已经讨论了很多,但我仍然没有找到解决方案。 这是我的代码:
GPUCameraRecorder class init
videoCamera = GPUImageVideoCamera(sessionPreset: AVCaptureSessionPresetiFrame960x540, cameraPosition: .Back)
videoCamera.outputImageOrientation = .LandscapeRight;
videoCamera.horizontallyMirrorFrontFacingCamera = true
filter = GPUImageFilter()
videoCamera.addTarget(filter)
view = GPUImageView(frame: frame)
view.fillMode = kGPUImageFillModePreserveAspectRatioAndFill
movieWriter = GPUImageMovieWriter(movieURL: output, size: view.frame.size)
movieWriter?.encodingLiveVideo = true
filter?.addTarget(movieWriter!)
filter?.addTarget(view as GPUImageView)
videoCamera.audioEncodingTarget = self.movieWriter!
videoCamera.startCameraCapture()
开始录制功能
func startRecording(){
println("Start recording.")
recording = true
dispatch_async(dispatch_get_main_queue()) {
var res = self.videoCamera.addAudioInputsAndOutputs()
println(res)
self.movieWriter!.startRecording()
}
}
结束录制功能
func stopRecording(){
println("Recording end.")
dispatch_async(dispatch_get_main_queue()) {
self.filter?.removeTarget(self.movieWriter!)
self.videoCamera.audioEncodingTarget = nil
self.movieWriter!.finishRecording()
self.putTorchOff()
self.delegate?.recordingEnd()
println("completed")
}
}
有什么建议吗?有人找到了一种没有黑框的方法吗?
答案 0 :(得分:4)
你试过这个吗?
在GPUImageMovieWriter.m中 添加代码:
[DefaultEvent("Click")]
public class MyRadionButton : RadionButton {
}
