dm365 jpgenc 出错

最近再调jpgenc ,用dvsdk2的demo可以用，但是我自己往codec server加的时候出现下面问题。
我的部分代码：
   hEngine = Engine_open(envp->engineName, NULL, NULL);
    printf("codec engine is %sn", envp->engineName);
 
    if (hEngine == NULL) [
        ERR("Failed to open codec engine %sn", envp->engineName);
        cleanup(THREAD_FAILURE);
    ]
 
params.maxWidth          = envp->imageWidth;
    params.maxHeight         = envp->imageHeight;
     if (colorSpace ==  ColorSpace_YUV420PSEMI) [
        params.forceChromaFormat = XDM_YUV_420SP;
    ] else [
        params.forceChromaFormat = XDM_YUV_422ILE;
    ]
dynParams.inputChromaFormat=XDM_YUV_420SP;
    dynParams.inputWidth      = params.maxWidth;
    dynParams.inputHeight     = params.maxHeight;
hIe = Ienc1_create(hEngine, envp->videoEncoder, ¶ms, &dynParams);
调试信息如下：
Algorithm creation FAILED; make sure that 1) alg params are correct/appropriate,

急求ti的大师怎么解决？谢了。
