libvlc获取一帧_android - 从android vlc媒体播放器获取当前帧 - 堆栈内存溢出

我找到了一个非常简单，非常快速的解决方案。 只需使用TextureView而不是SurfaceView ，然后在使用getBitmap()函数播放时随时检索图像，如下所示。

public class MainActivity extends AppCompatActivity implements TextureView.SurfaceTextureListener,

org.videolan.libvlc.media.MediaPlayer.OnBufferingUpdateListener,

org.videolan.libvlc.media.MediaPlayer.OnCompletionListener,

org.videolan.libvlc.media.MediaPlayer.OnPreparedListener,

org.videolan.libvlc.media.MediaPlayer.OnVideoSizeChangedListener {

private AppCompatActivity me = this;

private MediaPlayer mMediaPlayer;

private TextureView mTextureViewmTextureView;

private String mUrl = "/storage/emulated/0/videos/test.mp4";

private static final String TAG = "MainActivity";

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.content_main);

mMediaPlayer = new MediaPlayer(VLCInstance.get());

mTextureViewmTextureView = (TextureView) findViewById(R.id.player);

mTextureView.setSurfaceTextureListener(this);

}

private void attachViewSurface() {

final IVLCVout vlcVout = mMediaPlayer.getVLCVout();

mMediaPlayer.setScale(0);

vlcVout.detachViews();

vlcVout.setVideoView(mTextureView);

vlcVout.setWindowSize(mTextureView.getWidth(), mTextureView.getHeight());

vlcVout.attachViews();

mTextureView.setKeepScreenOn(true);

}

private void play(String path) {

try {

Media media;

if (new File(path).exists()) {

media = new Media(VLCInstance.get(), path);

} else {

media = new Media(VLCInstance.get(), Uri.parse(path));

}

mMediaPlayer.setMedia(media);

mMediaPlayer.play();

} catch (Exception e) {

Log.e(TAG, e.getMessage());

}

}

@Override

public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {

attachViewSurface();

if (mMediaPlayer.hasMedia())

mMediaPlayer.play();

else

play(mUrl);

}

public Bitmap getImage() {

return mTextureView.getBitmap();

}

}

VLCInstance.java：

import android.content.Context;

import android.util.Log;

import org.videolan.libvlc.LibVLC;

import org.videolan.libvlc.util.VLCUtil;

public class VLCInstance {

public final static String TAG = "VLC/Util/VLCInstance";

private static LibVLC sLibVLC = null;

/** A set of utility functions for the VLC application */

public synchronized static LibVLC get() throws IllegalStateException {

if (sLibVLC == null) {

final Context context = VLCApplication.getAppContext();

if(!VLCUtil.hasCompatibleCPU(context)) {

Log.e(TAG, VLCUtil.getErrorMsg());

throw new IllegalStateException("LibVLC initialisation failed: " + VLCUtil.getErrorMsg());

}

try{

sLibVLC = new LibVLC(context);

}catch (Throwable e){

e.printStackTrace();

}

}

return sLibVLC;

}

public static synchronized void restart(Context context) throws IllegalStateException {

if (sLibVLC != null) {

sLibVLC.release();

sLibVLC = new LibVLC(context);

}

}

}
