I'm new to Android and socket programming. I want to create an android application that transfer video live from device camera to PC. What first i do is to get a raw video data from PreviewCallback arguments and convert it to an RTP Packet. I was just using JLibRTP to do this. Regarding to transfer the packet i think, there are some related class: RtpPkt, RtpSession, and RtpSocket.
Here is my glance code:
DatagramSocket rtpSocket = new DatagramSocket();
DatagramSocket rtcpSocket = new new DatagramSocket();
RtpSession rtpSession = new RtpSession(rtpSocket, rtcpSocket);
public void surfaceCreated(SurfaceHolder holder) {
try {
camera = Camera.open();
camera.setPreviewCallback(new PreviewCallback() {
public void onPreviewFrame(byte[] _data, Camera _camera) {
int height = 240;
try {
rtps.sendData(_data);
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(), e.toString(),
Toast.LENGTH_SHORT).show();
}
}
});
camera.setPreviewDisplay(holder);
camera.startPreview();
} catch (IOException e) {
Log.d("CAMERA", e.getMessage());
}
}
I'm still wondering where i have to put address and port information. I know the code above still need correction from you any master. Thanks for advance..
I don't know if this library includes something to stream the packets to the pc, but if not, you've a problem, because android only supports RTP streaming since version 3.1 (API level 12). if your level is lower, you have to write your own "rtp-server" which is able to stream the packets from your device to the pc.
for more information check out the sipdroid project. they have created their own "rtp-server": http://code.google.com/p/sipdroid/source/browse/trunk/src/org/sipdroid/sipua/ui/VideoCamera.java
UPDATE:
another possibility is to use the ffserver from the ffmpeg libraries, but therefore you have to compile the libraries for android. here is a small tutorial how to do this and how to work with the libraries: How to Build FFmpeg for Android
UPDATE2:
the spydroid application is a very good example to stream videos from an android device without any external libraries.
