GPUImage2录制的视频上没有图像。
这是我的例子。如果有人能帮我找到解决办法,我将不胜感激。
@IBAction func capture(_ sender: UIButton) {
if (!isRecording) {
do {
self.isRecording = true
let documentsDir = try FileManager.default.url(for:.documentDirectory, in:.userDomainMask, appropriateFor:nil, create:true)
let fileURL = URL(string:"test.mp4", relativeTo:documentsDir)!
do {
try FileManager.default.removeItem(at:fileURL)
} catch {
}
movieOutput = try MovieOutput(URL:fileURL, size:Size(width:480, height:640), liveVideo:true)
camera.audioEncodingTarget = movieOutput
movieOutput!.startRecording()
} catch {
fatalError("Couldn't initialize movie, error: \(error)")
}
} else {
movieOutput?.finishRecording{
self.isRecording = false
self.camera.audioEncodingTarget = nil
self.movieOutput = nil
}
}
}
最佳答案
您忘记将目标添加到电影输出。
camera.addTarget(电影输出!)
do {
movieOutput = try MovieOutput(URL: currentVideoUrl, size: videoSize, liveVideo: true)
camera.audioEncodingTarget = movieOutput
camera.addTarget(movieOutput!)
movieOutput!.startRecording()
} catch {
print(error.localizedDescription)
}
