question about scalar framerate

Hi Badri,

          Thanks for you  reply. I can modify the framerate now, and I have another question to  consult.

          When the chain is runing, I want to dynamically modify the parameters.

          For example , I invoke the following API to modify the sclr Link framerate,     

         System_linkControl(sclrId, SCLR_LINK_CMD_SET_FRAME_RATE, &sclrParams, sizeof(sclrParams), TRUE);

         if I want a modified result, should I need to do the same modify to nsf Link and enc Link? or I just do this is ok.

Whenever input frame rate of encoder is modified the encoder should be reconfigured with correct inputFrameRate and targetFrameRate and bitrate else bitrate calculation will be wrong

Hi Badri,

        I set the encoder params as follows:

 for (i = 0; i < SRC_NUM_CH; i++)
 {
 encPrm.chCreateParams[i].format = IVIDEO_H264HP;
 encPrm.chCreateParams[i].profile = IH264_HIGH_PROFILE;
 encPrm.chCreateParams[i].dataLayout = IVIDEO_FIELD_SEPARATED;
 if (isProgressive)
 encPrm.chCreateParams[i].fieldMergeEncodeEnable = FALSE;
 else
 encPrm.chCreateParams[i].fieldMergeEncodeEnable = TRUE;
 encPrm.chCreateParams[i].maxBitRate = -1;
 encPrm.chCreateParams[i].encodingPreset = XDM_USER_DEFINED;
 encPrm.chCreateParams[i].rateControlPreset = 0;
 encPrm.chCreateParams[i].enableHighSpeed = 0;
 encPrm.chCreateParams[i].enableAnalyticinfo = 0;
 encPrm.chCreateParams[i].enableWaterMarking = 0;
 encPrm.chCreateParams[i].rateControlPreset = IVIDEO_STORAGE;
 
 encPrm.chCreateParams[i].defaultDynamicParams.inputFrameRate = 60;
 encPrm.chCreateParams[i].defaultDynamicParams.targetFrameRate = 60;
 encPrm.chCreateParams[i].defaultDynamicParams.intraFrameInterval = 60;
 encPrm.chCreateParams[i].defaultDynamicParams.interFrameInterval = 1;
 encPrm.chCreateParams[i].defaultDynamicParams.targetBitRate = (2 * 1000 * 1000);
 encPrm.chCreateParams[i].defaultDynamicParams.mvAccuracy = IVIDENC2_MOTIONVECTOR_QUARTERPEL;
 encPrm.chCreateParams[i].defaultDynamicParams.rcAlg = 0 ;
 encPrm.chCreateParams[i].defaultDynamicParams.qpMin = 10;
 encPrm.chCreateParams[i].defaultDynamicParams.qpMax = 40;
 encPrm.chCreateParams[i].defaultDynamicParams.qpInit = -1;
 encPrm.chCreateParams[i].defaultDynamicParams.vbrDuration = 8;
 encPrm.chCreateParams[i].defaultDynamicParams.vbrSensitivity = 0;
}

      I save the stream to a file, when I paly the file, I can find the framerate is 60.

     But when I invoke the API: 

                       System_linkControl(encId, ENC_LINK_CMD_PRINT_STATISTICS, NULL, 0, TRUE);

    It prints the statistics as follows, why the two framerate is not the same?

Scaler cannot do 2 channel 1080P60 scaling in real time so you will see reduced frame rate at encode link. Share the full logs of Vsys_printDetailedStatistics.

You have set NullSrc period as 60. So fps will be 1000/60 = 16.6 ~ 17 which is what the statistics is showing and this is expected. If you want 60 fps set the timerPeriod correctly to 16

Badri,

       Thank you very much.

       I have solved the problem.

      And when I  tried to change the framerate dynamically, I found I can not modify it.

      I invoke the Api, I can not modify the input and output framerate.       

                System_linkControl(sclrId, SCLR_LINK_CMD_SET_FRAME_RATE, &params, sizeof(params), TRUE);

     I also invoke the Api , the same does not change the framerate.

               System_linkControl(encId, ENC_LINK_CMD_SET_CODEC_INPUT_FPS, &encFps, sizeof(encFps), TRUE);
               System_linkControl(encId, ENC_LINK_CMD_SET_CODEC_FPS, &encTargetFps, sizeof(encTargetFps), TRUE);

   If I want to change the framerate dynamically, how should I do it?

The APis are correct..There is probably some issue with your application passing correct params. You can debug it by printing the performance logs and checking the encoder configuration by invoking encLink GET_DYNAMIC_PARAMS linkControl cmd.

If I just invoke  System_linkControl(encId, ENC_LINK_CMD_SET_CODEC_FPS, &encTargetFps, sizeof(encTargetFps)

I can change the targetFrameRate,
