通过流获取帧并在屏幕上显示 [英] Getting frames though a stream and display on screen

问题描述

我需要从服务器流式传输并在屏幕上显示流式内容...使用NSStream和NSInputStream以及NSOutputStream流式传输正常工作。如何在屏幕上显示它？

I have a requirement of streaming from server and displaying the streamed content on the screen...Streaming is working fine using NSStream, and NSInputStream and NSOutputStream.How can I display it on the screen?

使用的流看起来像@ http://191.168.143.41:1212/ ;

Stream used looks like @"http://191.168.143.41:1212/;

            if(stream == inputStream) {

            uint8_t buf[1024];
            unsigned int len = 0;

            len = [inputStream read:buf maxLength:1024];

            if(len > 0) {
                NSMutableData* datas=[[NSMutableData alloc] initWithLength:0];

                [datas appendBytes: (const void *)buf length:len];

                NSString *s = [[NSString alloc] initWithData:datas encoding:NSASCIIStringEncoding];

                [self readIn:s];
                NSLog(@"ss%@",s);
                 [self loadMovie:s]; //method for movie player 
            }

我试图将它显示在电影播放器​​中下面..

I tried to display this is in a movieplayer as below..

-(void_loadMovie:(NSString*)moviePrefix
   {
    NSString *path = [NSString stringWithFormat:@"%@.mjpg", moviePrefix];

    NSURL *url = [NSURL fileURLWithPath:path];
    if (url) {
        _moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];

       _moviePlayer.view.frame = CGRectMake(0, 70, 600, 450);
       _moviePlayer.controlStyle = MPMovieControlStyleNone;
        _moviePlayer.scalingMode = MPMovieScalingModeNone;
        [dic setObject:__moviePlayer forKey:path];
    }

}
[_moviePlayer prepareToPlay];
[self.view addSubview: _moviePlayer.view];
[self.view bringSubviewToFront:_moviePlayer.view];
[self.view addSubview: _moviePlayer.view];
[_moviePlayer play];  
}

是NSS tring * path = [NSString stringWithFormat：@％@。mjpg，moviePrefix];正确的方法??

Is NSString *path = [NSString stringWithFormat:@"%@.mjpg", moviePrefix]; correct way??

这显示黑屏。出了什么问题？
如果这种方式不正确，有没有其他方法可以显示这些帧？
任何人都可以帮我解决这个问题......

This displays a black screen.What is wrong? If this way is not correct,Is there any other way I can display those frames? Can anyone help me to solve this...
