智慧并不产生于学历,而是来自对于知识的终生不懈的追求。这篇文章主要讲述Android 使用PLDroidPlayer播放网络视频 依据视频角度自己主动旋转相关的知识，希望能为你提供帮助。
近期由于项目需求 。须要播放网络视频。于是乎 研究了一番 ，说说我遇到的那些坑
如今市面上有几个比較主流好用的第三方框架
- Vitamio （体积比較大，有商业化风险 github:https://github.com/yixia/VitamioBundle/）
- ijkplayer（B站下开源的框架 体积大 配置环境比較麻烦github:https://github.com/Bilibili/ijkplayer ）
- PLDroidPlayer（七牛依据ijkplayer二次开发的 定制简单 github:https://github.com/pili-engineering/PLDroidPlayer）
【Android 使用PLDroidPlayer播放网络视频 依据视频角度自己主动旋转】由于项目比較急，所以我用的比較简单的 PLDroidPlayer
首先把须要的jar包和jni文件拷到你的项目中
这个里面有非常多控件。你们能够依据自己的需求来用指定的控件。我用的是PLVideoTextureView
<
com.pili.pldroid.player.widget.PLVideoTextureView
android:id="@+id/video"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true" />
... prompt‘‘‘然后findviewbyid找到它

}这样就完毕了普通视频的播放和旋转视频播放
看似简单 事实上隐藏着大问题 。也就是我所说的大坑
如今我是这样推断角度的当视频的宽度大于高度的 我就觉得这是一个横屏的视频 ，也就是说假如这个视频是1330X720（我随便说的尺寸，仅仅为举例）如今宽度大于高度了 那么这就是一个横屏的视频，可是我仅仅要播放手机拍摄的视频就会发现视频被放大了 ，可是事实上我录制视频的时候是竖着排的 。可视播放的时候却给我横着过来了，然后我就去看这个手机拍摄视频的尺寸如今一般录制视频最低都是1280X720。恰好符合我推断的逻辑 。难道他真是横着的？然后我就用系统自带的播放器打开 ，竟然没有横过来 ，而是竖着播放的 ，可它是怎么知道这个方向呢？于是我在百度搜 。确实能够获取到本地视频的角度。可是好像低版本号好像不兼容，然后依据角度去推断 是否须要旋转。可是我这个是网络视频啊，网络视频怎么获取到视频角度啊 ？ 我第一反应是 上传视频的时候把宽高角度传到server ，然后获取的时候依据这个角度旋转 ，可是别人播放网络视频的时候也没有传角度过去啊 - -然后我就在github上面问那个作者，结果他说
“onInfo: 10001, 90”, 收到这个消息后。使用 PLVideoTextureView 的 setDisplayOrientation 旋转显示的方向。后面会补充这个回调的接口和文档。
我晕，你这不说 谁知道啊 坑死啊 --
然后我就改动了下代码
/**
* 视频的方向
*/
private int mVideoRotation;
private boolean needResume;
private PLMediaPlayer.OnInfoListener mOnInfoListener = new PLMediaPlayer.OnInfoListener() {
@Override
public boolean onInfo(PLMediaPlayer plMediaPlayer, int what, int extra) {
switch (what) {
case PLMediaPlayer.MEDIA_INFO_BUFFERING_START:
Logger.i("正在缓冲----");
//開始缓存，暂停播放
if (isPlaying()) {
//stopPlayer();
if (mVideoView != null) {
mVideoView.pause();
}
needResume = true;
}
rl_loading.setVisibility(View.VISIBLE);
break;
case PLMediaPlayer.MEDIA_INFO_BUFFERING_END:
case PLMediaPlayer.MEDIA_INFO_VIDEO_RENDERING_START:
Logger.i("缓冲完毕----");
//缓存完毕。继续播放
if (needResume)
//startPlayer();
if (mVideoView != null) {
mVideoView.start();
}
rl_loading.setVisibility(View.GONE);
break;
case PLMediaPlayer.MEDIA_INFO_BUFFERING_BYTES_UPDATE:
//显示 下载速度
Logger.e("download rate:" + extra);
//mListener.onDownloadRateChanged(arg2);
break;
case 10001:
//保存视频角度
mVideoRotation=extra;
break;
}
Logger.i("onInfo:" + what + "___" + extra);
return false;
}
};
然后在onVideoSizeChanged的回调里这样
mVideoView.setOnVideoSizeChangedListener(new PLMediaPlayer.OnVideoSizeChangedListener() {
@Override
public void onVideoSizeChanged(PLMediaPlayer plMediaPlayer, int width, int height) {
Logger.i("width:" + width + "---heightL:" + height);
if (width >
height&
&
mVideoRotation==0) {
//旋转方向
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
//假设视频角度是90度
if(mVideoRotation==90)
{
//旋转视频
mVideoView.setDisplayOrientation(270);
}}
});
这样 无论是什么视频播放最终正常了- -
