dm8168 自己创建link,实现读取host文件编码写入host文件问题

你好,

       我现在要实现的是在本地读取一帧yuv数据,通过m3video编码,再存成264文件。我的link是这样设计的,有没有问题?

       bitsout(linux)->bitsin(bios)->encode(m3)->bitsout(bios)->biosin(linux).

      SYSTEM_HOST_LINK_ID_IPC_BITS_OUT_0

      SYSTEM_VIDEO_LINK_ID_IPC_BITS_IN_0

      SYSTEM_LINK_ID_VENC_0

      SYSTEM_VIDEO_LINK_ID_IPC_BITS_OUT_0

      SYSTEM_HOST_LINK_ID_IPC_BITS_IN_0

     如果没有问题的话,现在是在mcfw/src_linux/links/ipcbitsout/ipcbitsoutlink_tsk.c

     中ipcbitsoutlink_releasebitsbuf函数中listmp_gethead在循环队列中过去帧数据返回为null是什么原因呢?求教。谢谢!
