t113多路解码占用cpu到100%

[likaienjoy]

我现在需要解码4路15帧的h264视频
AWStreamPlayer* pPlayerNew[4];
for(int i = 0; i < 4; i++)
{
pPlayerNew[i] = AWStreamPlayer::create(&decodeParam);
}
解码的时候：
while (decodePos < fileSize)
{
readTmpLen = ((fileSize - decodePos) < intputLen) ? (fileSize - decodePos) : intputLen;
fread(inputBuf, 1, readTmpLen, inFile);
nalLen = 0;
ret = find264NALFragment((char*)inputBuf, readTmpLen, &nalLen);
if (nalLen < 4) {
ALOGD("find264NALFragment fail nalLen:%d,ret:%d", nalLen, ret);
break;
}
ret = pPlayerNew[0]->decodeFrameDrectly((unsigned char *)inputBuf, nalLen);

    decodePos += nalLen;
    fseek(inFile, decodePos, SEEK_SET); //go to the real decode position.
    
     if (decodePos >= fileSize)
     {
         decodePos = 0;
         fseek(inFile, 0, SEEK_SET);
     }        
}  
for(int i = 0; i < 4; i++)
{
	AWStreamPlayer::destroy(pPlayerNew[i]);
}

发现create调用了initial函数里面的InitializeVideoDecoder会卡死cpu到100%。怎么解决？只是解码1路视频流，但是cpu会卡死
