Encode LINK InSkipFPS UserFPS

Ri-Ping YU

Expert 1460 points

Hi, TIers

I'm using DM8168 with RDK 4.0

There are 4 channels be encoded in my usecase, but the statistics information is abnormal,

one of the 4-channel : In Recv FPS = 30, In Skip FPS = 30, Out FPS = 0, there's no encoded frame output;

anothre channel : In Recv FPS = 30, UserFPS = 15, Out FPS = 15, I don't know what does this effect;

Appreciate for any reply!

The encoder frame skip is determined by

1. targetFrameRate that is part of dynamic params that application can set by invoking ENC_LINK_CMD_SET_CODEC_FPS

2. inputFrameRate that application can set by invoking ENC_LINK_CMD_SET_CODEC_INPUT_FPS

Both link commands should be invoked after creating encLink.make sure your application sets them to correct values.

I have invoked ENC_LINK_CMD_SET_CODEC_INPUT_FPS and ENC_LINK_CMD_SET_CODEC_FPS to modify input and target framerate after encLink created, as following:

////////////////////////////////////////////////////////////////////////////////////////////

    for (i = 0; i < 4; i ++)
    {
       EncLink_ChInputFpsParam inputPrm;
       inputPrm.chId = i;
       inputPrm.inputFps = 30;

       System_linkControl(esencId0, ENC_LINK_CMD_SET_CODEC_INPUT_FPS, (Void *)(&inputPrm), sizeof(EncLink_ChInputFpsParam), TRUE);

       EncLink_ChFpsParams outPrm;
       outPrm.chId = i;
       outPrm.targetFps = 30000;//30;
       if (3 == i)
           outPrm.targetBitRate   =   512000;
       else
           outPrm.targetBitRate = 1000000;//1000;

       System_linkControl(esencId0, ENC_LINK_CMD_SET_CODEC_FPS, (Void *)(&outPrm), sizeof(EncLink_ChFpsParams), TRUE);
    }

////////////////////////////////////////////////////////////////////////////////////////////

it do effect, I invoke ENC_LINK_CMD_GET_CODEC_PARAMS to get channel parameters, result is depicted in the file

parameters of each channel are correct, but skip FPS still exists.

By the way, the channel-3(with the issue) is derived from the path:swms0---->Scalar---->NSF---->IPC---->Enc...

Expect your further suggestion,Thanks a lot!

Channel 3 has Skip FPS and not User Skip FPS. This means it is dropping all frames .There was a bug in scaler link in RDK 4.0.Pls check if below patch resolves the issue
