Hi Ed,

I write a simple exampe app for testing vlc,but can only hear the sound,my code looks like this:

public class MainActivity extends ActionBarActivity implements IVideoPlayer{
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.player);
	    setVolumeControlStream(AudioManager.STREAM_MUSIC);
		v=getLibVlcInstance(ctxt);
		attachsurface();
        v.eventVideoPlayerActivityCreated(true);
	    loadMedia();
	}

	void attachsurface(){
		mSurface = (SurfaceView)findViewById(R.id.player_surface);
        mSurfaceHolder = mSurface.getHolder();
		String chroma = set().getString("chroma_format", "");
		if (LibVlcUtil.isGingerbreadOrLater() && chroma.equals("YV12")) {
			mSurfaceHolder.setFormat(ImageFormat.YV12);
		} else if (chroma.equals("RV16")) {
			mSurfaceHolder.setFormat(PixelFormat.RGB_565);
		} else {
			mSurfaceHolder.setFormat(PixelFormat.RGBX_8888);
		}
		mSurfaceHolder.addCallback(mSurfaceCallback);
	}

what's wrong with me? Thanks for your help!

You need to wait for surfaceChanged() then call libVLC.attachSurface().

I have already used surfaceChanged(),in my surfaceChanged(),I run mSurfaceHolder.addCallback(mSurfaceCallback),the callback like this:

Code: Select all


	private final Callback mSurfaceCallback = new Callback() {
		@Override
		public void surfaceChanged(SurfaceHolder holder, int format, int width,int height) {
			String chroma = set().getString("chroma_format", "");
			if (LibVlcUtil.isGingerbreadOrLater() && chroma.equals("YV12")) {
				mSurfaceHolder.setFormat(ImageFormat.YV12);
			} else if (chroma.equals("RV16")) {
				mSurfaceHolder.setFormat(PixelFormat.RGB_565);
			} else {
				mSurfaceHolder.setFormat(PixelFormat.RGBX_8888);
			}
			v.attachSurface(holder.getSurface(),MainActivity.this);
		}
		@Override
		public void surfaceCreated(SurfaceHolder holder) {
		}
		@Override
		public void surfaceDestroyed(SurfaceHolder holder) {
			v.detachSurface();
		}
	};

It seems that you are missing code or you are not presenting the whole.
