album video custom filter no sound #205

Open henryhwluk opened 7 years ago

henryhwluk commented 7 years ago

I read the album by reading the video file, after a custom filter, the video file is exported without sound, very confused, for the time being did not find an effective solution to the problem, I hope you can help or tips, the following is my relevant code :

//Render display renderView = RenderView(frame: CGRect(x: 0, y: UIScreen.Screen().height*0.08+0.5, width: UIScreen.Screen().width, height: UIScreen.Screen().width)) view.addSubview(renderView) movie = try MovieInput(url: url, playAtActualSpeed: true, loop: true) movieFilter = Normalfilter() movie --> movieFilter --> renderView movie.start()

//Sandbox directory address tmpFileURL = NSURL.fileURL(withPath: "(NSTemporaryDirectory())tmp(arc4random()).mp4") print(tmpFileURL) //Export
output = try! MovieOutput(URL: tmpFileURL, size: Size(width: Float(UIScreen.main.bounds.height), height: Float(UIScreen.main.bounds.width))) movie --> movieFilter --> output output.startRecording()

Finally, the export of the video file is no sound, is where I have a problem? @gillygize @wallerdev @mz2 @datskos @rounak @SoundandStuff

My previous commend was a misunderstanding, sorry :|

@henvyluk In MovieInput is a commend from @BradLarson: // TODO: Audio here So, I guess there is no sound setup for MovieInput component yet.

Yes, I have noticed. I also have access to relevant information, try to do this, but not yet achieved. I have seen someone to put forward the demand, it was also a Mac version (https: //github.com/BradLarson/GPUImage2/pull/140) , but the iOS version I was trying to be unsuccessful.
