示例1: onFrameAvailable
import android.graphics.SurfaceTexture; //導入方法依賴的package包/類
@Override
public void onFrameAvailable(SurfaceTexture surfaceTexture) {
surfaceTexture.updateTexImage();
float[] transform = new float[16]; // TODO - avoid alloc every frame
surfaceTexture.getTransformMatrix(transform);
long timestamp = mIncomingFramePts;// surfaceTexture.getTimestamp();
if (timestamp == 0) {
// Seeing this after device is toggled off/on with power button. The
// first frame back has a zero timestamp.
//
// MPEG4Writer thinks this is cause to abort() in native code, so it's very
// important that we just ignore the frame.
return;
}
handleFrameAvailable(transform, timestamp * 1000);
}
