如何使用RTMPStreamPublisher发布视频时在iPhone上存储视频？ [英] How to store video on iPhone while publishing video with RTMPStreamPublisher?

问题描述

现在我正在使用 RTMPStreamPublisher 在wowzaserver上发布视频。它正在成功上传，但有人能告诉我如何在上传到服务器时在iPhone上存储相同的视频吗？

Right now I am using RTMPStreamPublisher to publish the video at wowzaserver. It's uploading there successfully, but can anyone tell me how I can store the same video on the iPhone while uploading to the server?

我正在使用 https://github.com/slavavdovichenko/MediaLibDemos ，但没有太多文档可用。如果我可以存储发送的数据，那么我的工作就会成功。

I am using https://github.com/slavavdovichenko/MediaLibDemos, but there is not much documentation available. If I can just store the data that is sent for publication then my work will be successful.

这是他们用来上传流的方法，但我可以'找到一种方法在我的iPhone设备上存储相同的视频：

Here is the method they are using to upload the stream, but I can't find a way to store the same video on my iPhone device:

// ACTIONS

-(void)doConnect {
#if 0 // use ffmpeg rtmp 
    NSString *url = [NSString stringWithFormat:@"%@/%@", hostTextField.text, streamTextField.text];
    upstream = [[BroadcastStreamClient alloc] init:url  resolution:RESOLUTION_LOW];
    upstream.delegate = self;
    upstream.encoder = [MPMediaEncoder new];
    [upstream start];
    socket = [[RTMPClient alloc] init:host]
    btnConnect.title = @"Disconnect";     
    return;
#endif

#if 0 // use inside RTMPClient instance
    upstream = [[BroadcastStreamClient alloc] init:hostTextField.text resolution:RESOLUTION_LOW];
    //upstream = [[BroadcastStreamClient alloc] initOnlyAudio:hostTextField.text];
    //upstream = [[BroadcastStreamClient alloc] initOnlyVideo:hostTextField.text resolution:RESOLUTION_LOW];

#else // use outside RTMPClient instance

    if (!socket) {
        socket = [[RTMPClient alloc] init:hostTextField.text];
        if (!socket) {
            [self showAlert:@"Socket has not be created"];
            return;
        }
        [socket spawnSocketThread];
   }
    upstream = [[BroadcastStreamClient alloc] initWithClient:socket resolution:RESOLUTION_LOW];
#endif

    [upstream setVideoOrientation:AVCaptureVideoOrientationLandscapeRight];
    //[upstream setVideoOrientation:AVCaptureVideoOrientationLandscapeLeft];
    //[upstream setVideoBitrate:512000];
    upstream.delegate = self;
    [upstream stream:streamTextField.text publishType:PUBLISH_LIVE];
    //[upstream stream:streamTextField.text publishType:PUBLISH_RECORD];
    //[upstream stream:streamTextField.text publishType:PUBLISH_APPEND];
    btnConnect.title = @"Disconnect";     
}

我确实发现了 BroadcastStreamClient <的实例/ code>命名为upstream我可以通过以下行获得 AVCaptureSession

[upstream getCaptureSession];

如何使用此 AVCaptureSession 进行录制iPhone上的视频？

How can I use this AVCaptureSession for recording the video on the iPhone?

推荐答案

一旦你获得了 AVCaptureSession 你可以添加一个 AVCaptureMovieFileOutput 的实例，如下所示：

Once you got the AVCaptureSession you can add to it an instance of AVCaptureMovieFileOutput like this:

AVCaptureMovieFileOutput *movieFileOutput = [AVCaptureMovieFileOutput new];
if([captureSession canAddOutput:movieFileOutput]){
    [captureSession addOutput:movieFileOutput];
}

// Start recording
NSURL *outputURL = …
[movieFileOutput startRecordingToOutputFileURL:outputURL recordingDelegate:self];
