dm8127无法获取到编码数据

自己根据multich_encode_decode.c改了下usercase，目前是：

                                 CAMERA(VPSSM3)
                                      |
                                      |
                              FRAMES OUT(VPSSM3)          
                                      |                   
                                      |                   
                              FRAMES IN(VIDEOM3)          
                                      |                   
                                      |                   
                                 ENC(VIDEOM3)             
                                      |                   
                                      |                   
                               BITS OUT(VIDEOM3)          
                                      |                   
                                      |                   
                                  BITS IN(A8)   

但运行后App_ipcBitsRecvStreamFxn线程函数无法通过Venc_getBitstreamBuffer获取到编码数据，我怀疑bitsInNotifySem信号都没接收到，请大家帮看下是哪里出了问题。

程序执行后日志打印如下：

Chenfeng Wang：

我遇到与你同样的问题，但是我是用的是如下数据链路：                     

                         CAMERA(VPSSM3)                                      |                                      |                              IPCOUTVPSS(VPSSM3)                                                |                                                         |                                                 IPCINVIDEO(VIDEOM3)                                                |                                                         |                                                    ENC(VIDEOM3)                                                   |                                                         |                                                  BITS OUT(VIDEOM3)                                                |                                                         |                                                     BITS IN(A8)   

请问还有别人碰到类似问题吗？能否分享一下解决思路。
