推荐答案

我遇到了同样的问题，但最终我找到了方法.

I had the same problem but finally I found the way.

这是演练:

1- 在您的计算机 (SERVER) 上安装 VLC 并转到 Media->Streaming (Ctrl+S)

1- Install VLC on your computer (SERVER) and go to Media->Streaming (Ctrl+S)

2- 选择要流式传输的文件，或者如果要流式传输网络摄像头或...单击捕获设备"选项卡并进行配置，最后单击流式传输"按钮.

2- Select a file to stream or if you want to stream your webcam or... click on "Capture Device" tab and do the configuration and finally click on "Stream" button.

3- 在这里您应该进行流媒体服务器配置，只需转到选项"选项卡并粘贴以下命令:

3- Here you should do the streaming server configuration, just go to "Option" tab and paste the following command:

:sout=#transcode{vcodec=mp4v,vb=400,fps=10,width=176,height=144,acodec=mp4a,ab=32,channels=1,samplerate=22050}:rtp{sdp=rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/}

注意:将 YOURCOMPUTER_SERVER_IP_ADDR 替换为您的计算机 IP 地址或任何运行 VLC 的服务器...

NOTE: Replace YOURCOMPUTER_SERVER_IP_ADDR with your computer IP address or any server which is running VLC...

注意:您可以看到，视频编解码器是 android 支持的 MP4V.

NOTE: You can see, the video codec is MP4V which is supported by android.

4- 转到 eclipse 并为媒体播放创建一个新项目.创建一个 VideoView 对象并在 OnCreate() 函数中编写如下代码:

4- go to eclipse and create a new project for media playbak. create a VideoView object and in the OnCreate() function write some code like this:

mVideoView = (VideoView) findViewById(R.id.surface_view);

mVideoView.setVideoPath("rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/");
mVideoView.setMediaController(new MediaController(this));

5- 在设备上运行 apk(不是模拟器，我没有检查它)并等待播放开始.请考虑缓冲过程大约需要 10 秒...

5- run the apk on the device (not simulator, i did not check it) and wait for the playback to be started. please consider the buffering process will take about 10 seconds...

问题:有人知道如何减少缓冲时间并几乎实时播放视频吗?

Question: Anybody know how to reduce buffering time and play video almost live ?
