I have not searched for other free apps that are known to easily play RTSP
streams on Android. Sorry.
With respect to my working solution recipe, I am glad to share. There are 4
parts to this.
1 - a local LAN connection between the stream server and the Android
client. I used my local WiFi.
2 - ffmpeg to transcode the content. For the content, I used a local video
file that I had captured on an Android device and copied to my server
machine.
3 - ffserver to stream the content
4 - a test Android app.
For #2, the command I used was:
ffmpeg -i test.mp4 http://10.10.10.143:8090/feed1.ffm
For #3, here is my complete ffserver configuration file.
Port 8090
BindAddress 0.0.0.0
RTSPPort 7654
RTSPBindAddress 0.0.0.0
MaxClients 4
MaxBandwidth 10000
NoDaemon
<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 20M
ACL allow 10.10.10.0 10.10.10.255
</Feed>
<Stream mystream.sdp>
Feed feed1.ffm
Format rtp
VideoCodec libx264
VideoSize 640x480
VideoQMin 1
VideoQMax 20
AVOptionVideo flags +global_header
NoAudio
</Stream>
<Stream status.html>
Format status
ACL allow 10.10.10.0 10.10.10.255
</Stream>
For #4, here is my Android test app. It consists of a layout file and a
single activity.
The layout file name is "activity_main.xml" and its contents are:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<VideoView android:id="@+id/VideoView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</RelativeLayout>
The activity file name is "MainActivity.java" and its contents are:
package com.optimaldesignco.stream;
import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.net.Uri;
import android.widget.MediaController;
import android.widget.VideoView;
public class MainActivity extends Activity
{
VideoView videoView;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
videoView = null;
setContentView(R.layout.activity_main);
videoView =(VideoView)findViewById(R.id.VideoView);
MediaController mediaController= new MediaController(this);
mediaController.setAnchorView(videoView);
// Uri uri =
Uri.parse("rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov");
Uri uri = Uri.parse("rtsp://10.10.10.143:7654/mystream.sdp");
videoView.setMediaController(mediaController);
videoView.setVideoURI(uri);
videoView.requestFocus();
videoView.start();
}
}
