Detailed Description

R5Camera / R5VideoSource class hierarchy demonstrates how Red5 Professional enables rapid streaming development.
. The baseclass handles the preparation of the hardware encoder, and the subclass provides the source images used for streaming.
Extenders of Red5VideoSource must provide YV12 image data in byte buffers. You can also override the size used in the 'open' method.


initSource(){
setFrameType(ImageFormat.YV12);
width=320;
height=240;
}



At runtime, acquire the YV12 image data, and convert it to the required MediaCodec frame type.
prepareFrame(inptYV12, output);

To send a frame, encode it.
encode(output, nanoTime, false);//if the frame size changes, reset must be true.

Constructor & Destructor Documentation

R5Camera()

com.red5pro.streaming.source.R5Camera.R5Camera ( Camera  camera, int  preferedWidth, int  preferedHeight  )

inline

Initiate a camera with a desired resolution. It will try to pick a resolution as close as it can.
It is preferable to iterate the supported preview resolutions and choose one brfore hand.

Parameters

camera
preferedWidth
preferedHeight

Member Function Documentation

onPreviewFrame()

void com.red5pro.streaming.source.R5Camera.onPreviewFrame ( byte[]  data, Camera  camera  )

setCamera()

void com.red5pro.streaming.source.R5Camera.setCamera ( Camera  camera )
