[android-developers] YUV to h263/h264 compression on android to stream video
hi,
I am trying stream video from android to network and receiving it on a
server that I had written in java.
I am capturing YUV data on onPreviewFrame method on Camera convert
with yuv in jpeg and sending it to the server where I convert this
data to image and displaying it.
Everything works fine but the problem is that there is a lot much
delay and size of images in the streaming process as I am sending the
data directly. Is there some way of encoding this YUV data to h263 or
h264 format so that I can minimize the delay and the size of images?
Also MediaRecorder have ability to record the video in the available
standard video format but it stores the video to a file on sdcard. Is
there any way of getting a stream from that video which is being
recorded so that I can stream it to the network? This will reduce my
efforts in conversion process.
here is my code for conversion.
public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
int format = parameters.getPreviewFormat();
//YUV formats require more conversion
if (format == ImageFormat.NV21 /*|| format ==
ImageFormat.YUY2 || format == ImageFormat.NV16*/)
{
int w = parameters.getPreviewSize().width;
int h = parameters.getPreviewSize().height;
// Get the YuV image
YuvImage yuv_image = new YuvImage(data, format, w, h,
null);
// Convert YuV to Jpeg
Rect rect = new Rect(0, 0, w, h);
ByteArrayOutputStream output_stream = new
ByteArrayOutputStream();
yuv_image.compressToJpeg(rect, 100, output_stream);
byte[] byt=output_stream.toByteArray();
and send these bytes to network. how to reduce the size of images in
KB and also delay?
Thanks

hi,
Please anyone tell me that when onPreviewFrame call it send first
frame of the preview to socket but when it callback it get exception
and does send any frame to socket, I want to send images from
onPreviewFrame continuously. Please tell me what's the reason, and
sorry for my English. Here is my code.
public void surfaceCreated(SurfaceHolder holder) {
// The Surface has been created, acquire the camera and tell it
where
// to draw.
//connection to server
try {
socket = new Socket(192.168.1.220, );
obj = new ObjectOutputStream(socket.getOutputStream());
} catch (UnknownHostException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
camera = Camera.open();
try {
camera.setPreviewDisplay(holder);
camera.setPreviewCallback(new PreviewCallback() {
// Called for each frame previewed
// @SuppressWarnings(null)
public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
int format = parameters.getPreviewFormat();
//YUV formats require more conversion
if (format == ImageFormat.NV21 /*|| format ==
ImageFormat.YUY2 || format == ImageFormat.NV16*/)
{
int w = parameters.getPreviewSize().width;
int h = parameters.getPreviewSize().height;
// Get the YuV image
YuvImage yuv_image = new YuvImage(data, format, w, h,
null);
// Convert YuV to Jpeg
Rect rect = new Rect(0, 0, w, h);
ByteArrayOutputStream output_stream = new
ByteArrayOutputStream();
yuv_image.compressToJpeg(rect, 100, output_stream);
byte[] byt=output_stream.toByteArray();
try
{
obj.writeObject(byt);
obj.flush();
}
catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
}
Preview.this.invalidate();
}
}
});
} catch (IOException e) {
e.printStackTrace();
}
}
Thanks and regards

//BufferedOutputStream imagebos = new
BufferedOutputStream(dos);
dos.writeInt(len);
if (len 0) {
