Question

对于我的应用程序，我必须从一个decklink卡流式传输到Android应用程序（我必须是一个实时流，因此HLS或RTSP似乎是很好的解决方案，因为我的应用程序针对Android 3+）。我使用decklink sdk重新编译了VLC，并且我能够通过网络直播到另一台PC（但它只能在60秒内使用RTSP）。

以下是我的尝试：

HTTP Stream：

./vlc -vvv decklink:// --sout
'#transcode{vcodec=mp4v,acodec=mpga,vb=56,ab=24,channels=1}
:standard{access=http{use-key-frames},mux=ts,dst=:3001/stream.mpeg}'

它适用于Android VLC 0.0.11，但仅适用于WiFi，不适用于3G。我无法使用VideoView在我的应用程序中播放它。这是我使用的代码和相应的错误消息：

String url = "http://134.246.63.169:5554/stream.mpeg";

VideoView videoView = (VideoView) this.findViewById(R.id.videoView);
videoView.setVideoURI(Uri.parse(url));        
videoView.setMediaController(new MediaController(this));
videoView.requestFocus();  
videoView.start();

错误讯息：

RTSP：

我使用了Google在this page上推荐的编码选项，例如：

视频编解码器：h264
音频编解码器：AAC
视频比特率：56
音频比特率：24
音频频道：1

尺寸：176x144

./vlc -vvv decklink:// --sout-ffmpeg-strict=-2 --sout
'#transcode{width=176,height=144,vcodec=h264,acodec=mp4a,vb=56,ab=24,channels=1}
:rtp{dst=134.246.63.169,port-video=5554,port-audio=5556,sdp=rtsp://134.246.63.169:5554/stream.sdp}'

我可以在VLC桌面播放流，但不能在Android中播放（即使在Android VLC版本或默认的Google视频播放器中：/）。如果我没有指定多路复用器，我也可以将它播放为QuickTime（如果我指定多路复用器，无论是ts还是ps，我都没有视频。如果我尝试另一个多路复用器，VLC告诉我，我只允许使用ts或者在RTP中的ps）

如果我尝试使用Google视频播放器，我会在locat中收到这些消息：

我想问题是“状态：RTSP / 1.0 461不支持的传输”，但我看不出我能改变什么：我已经打开了我使用的端口，我确实收到了另一台计算机上的视频

在Android手机上，我可以播放一些我在网上找到的rtsp流，例如：rtsp：//184.72.239.149/vod/mp4:BigBuckBunny_115k.mov。所以它应该是可能的。

如果有人可以提供帮助......！

Answer 1

最后这是一个网络问题，我通过MacBook WiFi共享连接我的设备，似乎它阻止了RTSP流。现在我使用路由器，它在RTSP中工作（我仍然无法在Android VideoView中接收HTTP流）。尽管如此，我仍然有一个超时问题：RTSP流在60秒后停止，因为VideoView不发送保持活动消息。我会尝试自己做...

Answer 2

我用openRTSP命令测试了我的rtsp服务器。

这是UDP端口被阻止了。

如果没有-t：

访问rtsp

-> $ openRTSP <rtsp_url>

我有记录告诉我：

// omit lots of lines..
Created receiver for "video/H264" subsession (client ports 63346-63347)

Received a complete SETUP response:

因此改为TCP：

它开始成功接收数据。

现在我必须弄清楚如何在Android中自动切换到TCP。

Answer 3

请尝试VLC：

vlc some_file.mp4 -I http --sout＆＃34; #transcode {soverlay，ab = 128，samplerate = 44100，channels = 2，acodec = mp4a，vcodec = h264，width = 480，height = 270， VFILTER =＆＃34;帆布{宽度= 480，高度= 270，纵横= 16：9}＆＃34;，FPS = 25，VB = 800，VENC = X264 {水平= 12，无CABAC，次亚= 20 ，线程= 4，B-帧= 0，最小在keyint = 1，在keyint = 50}}：收集：RTP {MP4A-个大气压，SDP = RTSP：//0.0.0.0：5554 / stream.sdp}＆＃34; < / p>

和android代码：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final VideoView vidView = (VideoView)findViewById(R.id.myVideo);

        MediaController vidControl = new MediaController(this);
        vidControl.setAnchorView(vidView);
        vidView.setMediaController(vidControl);

        vidView.setVideoPath("rtsp://137.110.92.231:5554/stream.sdp");

        vidView.start();
        }

Answer 4

使用 MediaPlayer 它支持HTTP和RTSP网络协议。 http://developer.android.com/guide/topics/media/mediaplayer.html#mediaplayer http://developer.android.com/guide/appendix/media-formats.html#recommendations

VLC RTSP直播到Android
