How to feed raw data from file to encode?

Hi,

How to feed data read from file to encode? The ipcFramesSendFxn function I wrote is list below, but getEmptyVideoFrames = 0. What's wrong?

static Void *Venc_ipcFramesSendFxn(Void *prm)
{
    Venc_IpcFramesCtrl *ipcFramesObj = (Venc_IpcFramesCtrl *) prm;
    Venc_IpcFramesCtrlThrObj *thrObj = &ipcFramesObj->thrObj;

    static Int printStatsInterval = 0;
    VIDFrame_BufList bufList;
    Int status;
 Int count;

 VIDEO_CHANNEL_LIST_INFO_S chInfoList;
 Int i;

    OSA_printf("CHAINS_IPCFRAMES:%s:Entered...",__func__);
    OSA_semWait(&thrObj->framesOutNotifySem,OSA_TIMEOUT_FOREVER);
    OSA_printf("@_@ CHAINS_IPCFRAMES:Received first frame notify...");

    while (FALSE == thrObj->exitFramesOutThread)
    {
        OSA_waitMsecs(VENC_IPCFRAMES_SENDFXN_PERIOD_MS);

  /* We need to initialize the frameObj only at start time and
   * not at create time. This is because the SharedRegion is
   * initialized only after Vsys_create().
   * Also the number of channels to be displayed can be queries
   * from VDIS module only after Vdis_create()
   */
  status = Venc_getChannelInfo(&chInfoList);

  OSA_assert(status == ERROR_NONE);
  Venc_ipcFramesInitFrameObj(gVenc_ctrl.ipcFrames.frameObj,
            VENC_IPCFRAMES_MAX_NUM_ALLOC_FRAMES,
            &chInfoList);

        Venc_ipcFramesFillBufInfo(&bufList,
                              ipcFramesObj->frameObj,
                              OSA_ARRAYSIZE(ipcFramesObj->frameObj));

  if (bufList.numFrames)
  {
   status = Venc_putFullVideoFrames(&bufList);
   OSA_assert(0 == status);
  }
  status =  Venc_getEmptyVideoFrames(&bufList,0);
  OSA_assert(0 == status);

        if (bufList.numFrames)
        {
            Venc_ipcFramesPrintFullFrameListInfo(&bufList,"EmptyFrameList");
            Venc_ipcFramesFreeFrameBuf(&bufList,
                                           ipcFramesObj->frameObj,
                                           OSA_ARRAYSIZE(ipcFramesObj->frameObj));
        }

        if ((printStatsInterval % VENC_IPCFRAMES_INFO_PRINT_INTERVAL) == 0)
        {
            OSA_printf("VENC_IPCFRAMES:%s:INFO: periodic print..",__func__);
        }

        printStatsInterval++;
    }
    OSA_printf("VENC_IPCFRAMES:%s:Leaving...",__func__);
    return NULL;
}
