我正在使用下面的代码在 android 设备上显示实时 RTSP 流。它工作正常，但问题是视频比现实晚了大约 2-4 秒，而 Xmeye 应用程序晚了 2 秒。我在 android studio 日志中收到 “图片为时已晚无法显示”的音调，到目前为止，所有 libvlc 配置（在代码中注释掉）都没有帮助。libvlc 版本是 2.5.4，它在我的项目中作为一个模块实现。

是否有任何配置或替代解决方案来克服这个问题？

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    Window window = getWindow();
    window.setFlags(
            WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
//        args.add("--ffmpeg-hw");
//        args.add("--avcodec-fast");
//        args.add("--avcodec-dr");
//        args.add("--avcodec-skiploopfilter=4");
//        args.add("--rtsp-frame-buffer-size=947483647");
//        args.add("--rtsp-frame-buffer-size=13107200");
//        args.add("--network-caching=2000"); // reduces the quality
//        args.add("--live-caching==2000");
//        args.add("--no-plugins-cache");// prevent from working
//        args.add("--sout-rtp-caching=1000"); // prevent from working
    mLibVLC = new LibVLC(this, args);
    mMediaPlayer = new MediaPlayer(mLibVLC);
    ...
    }
  @Override
protected void onStart() {
    super.onStart();

    final IVLCVout vlcVout = mMediaPlayer.getVLCVout();

    if (mVideoSurface != null) {
        vlcVout.setVideoView(mVideoSurface);
        if (mSubtitlesSurface != null)
            vlcVout.setSubtitlesView(mSubtitlesSurface);
    } else
        vlcVout.setVideoView(mVideoTexture);
    vlcVout.attachViews(this);
    startVideo();
}

private void startVideo() {
    setMedia();

    if (mOnLayoutChangeListener == null) {
        mOnLayoutChangeListener = new View.OnLayoutChangeListener() {
            private final Runnable mRunnable = new Runnable() {
                @Override
                public void run() {
                    updateVideoSurfaces();
                }
            };

            @Override
            public void onLayoutChange(View v, int left, int top, int right,
                                       int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
                if (left != oldLeft || top != oldTop || right != oldRight || bottom != oldBottom) {
                    mHandler.removeCallbacks(mRunnable);
                    mHandler.post(mRunnable);
                }
            }
        };
    }
    mVideoSurfaceFrame.addOnLayoutChangeListener(mOnLayoutChangeListener);
}

private void setMedia() {
    try {
        final Media media = new Media(mLibVLC, Uri.parse(getRTSPURL()));
        mMediaPlayer.setMedia(media);
        media.release();
    } catch (Exception e) {
        throw new RuntimeException("Invalid asset folder");
    }
    mMediaPlayer.play();

大部分代码来自 vlc android java-sample。参考

更新

感谢 mtz 的评论，我将 libvlc 更新为 3.0.0 并添加了这行代码。

media.addOption(":codec=mediacodec_ndk,mediacodec_jni,none");

现在，除了我反复收到以下错误外，“图片太迟无法显示”错误仅在开始时或使用 sd 质量视频时发生几次。

当蓝牙设备连接到手机时，我大多会收到此错误并且没有输出
