8168采集sdi，720p，视频预览正常，但是没有编码，
串口打印如下：

可以看出有数据进入编码器m3video，但m3video没数据出来，a8端的que里没任何数据，问题怎么调试?
采集link的参数配置如下：
#define SYSTEM_CAPT_VIDEO_CAPTURE_MODE_7601 EVICE_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_ACTVID_VSYNC
pCaptureInstPrm = &capturePrm.vipInst[0];
pCaptureInstPrm->vipInstId = SYSTEM_CAPTURE_INST_VIP0_PORTA;
pCaptureInstPrm->videoDecoderId = SYSTEM_DEVICE_VID_DEC_GV7601_DRV;
pCaptureInstPrm->videoCaptureMode = SYSTEM_CAPT_VIDEO_CAPTURE_MODE_7601;//gv7601 better
pCaptureInstPrm->videoIfMode = SYSTEM_CAPT_VIDEO_IF_MODE_8BIT;//SYSTEM_CAPT_VIDEO_IF_MODE_8BIT;
pCaptureInstPrm->inDataFormat = SYSTEM_DF_YUV422P;
pCaptureInstPrm->standard = VSYS_STD_720P_60;
pCaptureInstPrm->numOutput = 1;
采集模式只有EVICE_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_ACTVID_VSYNC和
DEVICE_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_HSYNC_VSYNC预览正常，但这两个都是没有编码，不知道还有那些参数没设对导致没有编码
