用嵌入式视频编写iPhone应用程序 [英] writing an iPhone application with embedded video

问题描述

我正在研究iPhone应用程序的视频流，我可能不得不在不久的将来写这篇文章。该应用程序除了流视频之外还做了很多，但视频方面是我没有经验的部分。

I am researching video streaming for an iPhone application that I may have to write in the near future. The application does a whole lot other than stream video, but video aspect is the part that I have no experience with.

任何人都知道有关编写流视频应用程序的任何好文章？

Anyone know of any good articles on writing streaming video apps?

谷歌似乎用我所寻求的所有东西淹没了我。

Google seems to inundate me with links that have everything not to do what I seek.

谢谢，

Apple提供有关媒体框架的良好文档i ntheir docs。

搜索MPMoviePlayerController。以下示例代码从URL播放影片。 （免责声明，此代码取自Apple）。

Search for MPMoviePlayerController. The following sample code plays a movie from a URL. (disclaimer, this code lifted from Apple).

-(void)playMovieAtURL:(NSURL*)theURL 

{
    MPMoviePlayerController* theMovie=[[MPMoviePlayerController alloc] initWithContentURL:theURL]; 
    theMovie.scalingMode=MPMovieScalingModeAspectFill; 
    theMovie.userCanShowTransportControls=NO;

    // Register for the playback finished notification. 

    [[NSNotificationCenter defaultCenter] addObserver:self 
                                            selector:@selector(myMovieFinishedCallback:) 
                                                name:MPMoviePlayerPlaybackDidFinishNotification 
                                              object:theMovie]; 

    // Movie playback is asynchronous, so this method returns immediately. 
    [theMovie play]; 
} 

// When the movie is done,release the controller. 
-(void)myMovieFinishedCallback:(NSNotification*)aNotification 
{
    MPMoviePlayerController* theMovie=[aNotification object]; 
    [[NSNotificationCenter defaultCenter] removeObserver:self 
                                                    name:MPMoviePlayerPlaybackDidFinishNotification 
                                                  object:theMovie]; 

    // Release the movie instance created in playMovieAtURL
    [theMovie release]; 
}
