从log来看，是本底层报了的错误。麻烦尽快修复。^-^

经过添加log发现是由于连接异常断开，导致出现崩溃。更换网络环境后，没有出现奔溃，可能是连接断开情况下，上层依然往下层push数据导致堆栈溢出。
public class EasyRTMP implements Pusher {
private boolean isRTMPConnectNormal = false; // 用于标记连接是否正常

@OverRide
public synchronized void initPush(final String url, final Context context, final InitCallback callback, int fps) {
/*

*/
Log.e(TAG, "startpush begin");
mPusherObj = init(url, RTMP_KEY, context, new OnInitPusherCallback() {
int code = Integer.MAX_VALUE;
@OverRide
public void onCallback(int code) {
if (code != this.code) {
this.code = code;
switch (code) {

break;

break;
}
Log.e("cclin", "RTMP 当前连接状态："+isRTMPConnectNormal);
if (callback != null) callback.onCallback(code);
}
}
},
fps);
Log.e(TAG, "startpush end");
}

public synchronized void push(byte[] data, int offset, int length, long timestamp, int type){
    mTotal += length;
    if (type == 1){
        mTotalFrms++;
    }
    long interval = System.currentTimeMillis() - pPreviewTS;
    if (interval >= 3000){
        long bps = mTotal * 1000 / (interval);
        long fps = mTotalFrms * 1000 / (interval);
        Log.i(TAG, String.format("bps:%d, fps:%d", fps, bps)+"  myTid = "+android.os.Process.myTid());
        pPreviewTS = System.currentTimeMillis();
        mTotal = 0;
        mTotalFrms = 0;
        if (mCameraId == Camera.CameraInfo.CAMERA_FACING_BACK)
            BUS.post(new StreamStatBack((int)fps, (int)bps));
        else
            BUS.post(new StreamStatFront((int)fps, (int)bps));
    }
    if (mPusherObj == 0 || !isRTMPConnectNormal) return;

    push(mPusherObj, data, offset, length, timestamp,type);
}

不知这样修改，是否能够优化push逻辑呢？
