vitamio简述

vitamio

一款开源的多媒体框架，全硬件加速和渲染。

新特性

1. 基于最新的ffmpeg2.0 版本
2. 支持ffmpegAV 选项，可以自定义协议头
3. 支持多种硬件平台，x86,mips eg

VideoView

ViewView继承自SurfaceView，内部有引用这mediaPlayer（Vitamio本身的）,以及播放相关的mediaController。
1. 调用简单：
//对于流媒体，可以通过uri进行播放
mVideoView.setVideoPath(path);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();

    mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mediaPlayer) {
            // optional need Vitamio 4.0
            mediaPlayer.setPlaybackSpeed(1.0f);
        }
    });

1. VideoView高内聚
   mediaPlayer对象的使用

         mMediaPlayer = new MediaPlayer(mContext, mHardwareDecoder);
         mMediaPlayer.setOnPreparedListener(mPreparedListener);
         mMediaPlayer.setOnVideoSizeChangedListener(mSizeChangedListener);
         mMediaPlayer.setOnCompletionListener(mCompletionListener);
         mMediaPlayer.setOnErrorListener(mErrorListener);
         mMediaPlayer.setOnBufferingUpdateListener(mBufferingUpdateListener);
         mMediaPlayer.setOnInfoListener(mInfoListener);
         mMediaPlayer.setOnSeekCompleteListener(mSeekCompleteListener);
         mMediaPlayer.setOnTimedTextListener(mTimedTextListener);
         mMediaPlayer.setDataSource(mContext, mUri, mHeaders);  //可以设置多种多样的数据源
         mMediaPlayer.setDisplay(mSurfaceHolder);
         mMediaPlayer.setBufferSize(mBufSize);
         mMediaPlayer.setVideoChroma(mVideoChroma == MediaPlayer.VIDEOCHROMA_RGB565 ? MediaPlayer.VIDEOCHROMA_RGB565 : MediaPlayer.VIDEOCHROMA_RGBA);
         mMediaPlayer.setScreenOnWhilePlaying(true);  //注意，此处的方法最终调用的是 hodler的方法 setKeepScreenOn(True)
         mMediaPlayer.prepareAsync();
   
         //回调接口丰富 onPrepared onError onCompelete  onBuffer onSeek onInfo onTimeText
