whi*_*rue 5 video android vlc libvlc vlc-android
经过 3 天的旅程，我终于编译了 libvlc-3.0.0-2.1.0.aar，用于将 VLC 播放器嵌入到我的 Android（电视）应用程序中。
\n\n改编LibVLC Android 示例后到我的项目中后，我终于运行了该应用程序。
\n\n问题：仅播放音频。视频永远不会出现（表面视图保持黑色）。我用不同的视频进行了测试，图像从未出现。
\n\n知道为什么视频没有播放吗？这是我尝试播放的视频示例（http://www.sample-videos.com/video/mp4/240/big_buck_bunny_240p_50mb.mp4）
\n\n我的设置：\n我已经刻录了Android 电视图像刻录到我的 RPI3 中，并且该应用程序正在其中运行。
\n\n更新：我已经尝试过 VLC 原始应用程序（来自 apk），并且发生了同样的情况。
\n\n这是我的活动的代码：

可悲的事实是libvlc 示例已经相当过时了。
正如发帖者所评论的，也许避免 VLC 是一种选择。
不管好坏，libvlc 在我的旧 Android Tab（nexus 7）上工作。
至于网上的示例，使用旧版本 NDK 编译的 libvlc 似乎包含 TEXTREL，并且 github 上的许多示例都受其影响。
我使用自编译的 libvlc-3.0.0-2.1.1.aar 并进行了以下调整。
删除的接口：
LibVLC.HardwareAccelerationError //is now gone(idk what replaces this!).
更改了实施：
IVLCVout.callback.onNewLayout
到
IVLCVout.OnNewVideoLayoutListener.onNewVideoLayout
实例化 LibVLC
mLibVLC = new LibVLC();
mLibVLC = new LibVLC(options);
到
mLibVLC = new LibVLC(getApplicationContext());
mLibVLC = new LibVLC(getApplicationContext(),options);
它应该向我们显示可以播放的视频列表，但我只能看到一个仅播放音频的按钮，因此如果您想测试 VLC 视频功能，也许您需要添加一些代码来启动 VideoActivity 并调用它。
public void startVideoIntent(String path){
Intent intent = new Intent(MainActivity.this, VideoActivity.class);
intent.putExtra(VideoActivity.LOCATION, (String) path);
mPlayingVideo = true;
startActivity(intent);
}
