这个是专门用来给android播放flv的播放器。他是基于Mediacodec的 只能解析FLV包含H264+AAC的音视频

使用方法：

    if (flv == null) {
        flv = new Flvplayer();

        flv.setCallBack(new HttpNet.CallBack() {
            @Override
            public void onError(int errorCode) {
                runUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(VideoPlayerActivity.this.getApplicationContext(), "网络信号不好或视频已经播完", Toast.LENGTH_SHORT).show();
                        VideoPlayerActivity.this.finish();
                    }
                });
            }

            @Override
            public void onStatus(int statusCode, String msg) {
                Log.e("flvflv", "msg:" + msg);
            }

            @Override
            public void onWidthHeight(int width, int height) {

            }

            @Override
            public void onFinsh() {

            }
        });
    }

    flv.connect(url, surfaceTexture);
