DM6467T Videnc1_process takes 22ms that don't allow 60fps at output ! How can i perform a better time process ?

Hi all,

I found some precision about the time Videnc1_process() :

The process takes 13ms for IntraFrame and 22ms to process Inter Frame.

Using only intra Frame makes horrible display,and adding to a queue element we can reach 60fps @ output.

gst-launch -v ticapturesrc num-buffe                                                 
rs=5000 ! 'video/x-raw-yuv,width=(int)1280,height=(int)720,framerate=(fraction)6                                                 
0/1' ! TIPrepEncBuf contiguousInputFrame=TRUE ! 'video/x-raw-yuv, width=1280, he                                                 
ight=720, format=(fourcc)NV12' ! queue ! TIVidenc1 codecName=h264enc engineName=                                                 
codecServer rateControlPreset=3 encodingPreset=2 intraFrame=1 bitRate=4000000 fr                                                 
amerate=60/1 ! dmaiperf print-arm-load=true engine-name=codecServer ! fakesink s                                                 
ilent=true

Any hints to reduce the time for inter frame encoding ?

Hello Mike,

I also have the evaluation board of the DM6467T.

I succeed to configure the FHD for 1080P30 encode, however didn't succeed to configure it to 720P60.

When taking the 720P codec, it seems that it encodes at 60fps but it reports frame rate of 25 fps.

Can you please send me the configuration of the FHD for 720P60?

Hi Mordehay,

I use the same params as the 1080p30 encode process.

i copy all the ohter params :

    IH264FHDVENC_Params   extHDParams = {
            Venc1_Params_DEFAULT,

            66,     // profileIdc;                  66=Baseline Profile
            40,     // levelIdc;                    40=Level 4.0
            0,      // EntropyCodingMode;           0=CAVLC

 };

 and dynparams :

    IH264FHDVENC_DynamicParams extHDDynParams = {
        //Venc1_DynamicParams_DEFAULT,
            {
                sizeof(IH264FHDVENC_DynamicParams),   /* size */
                1920,//144;                       /* inputHeight */

                0,                                /* captureWidth */

                0x0                               /* mbDataFlag */
            },

        0,      // ME1080iMode;                 0 = High video quality
        0,      // MVDataFlag;                  0 = MV data disabled
        1,      // Transform8x8DisableFlag      1 = 8x8 Transforms Disabled

        1000,    // maxDelay
        90,     // MaxSlicesSupported
    };

Then i set them to:

        params = (VIDENC1_Params*)&extHDParams;
        dynParams = (VIDENC1_DynamicParams*)&extHDDynParams;
        params->size = sizeof(IH264FHDVENC_Params);
        params->encodingPreset = XDM_DEFAULT;
        params->maxHeight = 1088; //videnc1->height; //1088;
        params->maxWidth = 1920; // videnc1->width; //1920;
        params->maxFrameRate = 30000;
        params->maxBitRate = 10000000;
        params->dataEndianness = XDM_LE_32;
        params->maxInterFrameInterval = 0;
        params->inputChromaFormat = XDM_YUV_420SP;
        params->inputContentType = IVIDEO_PROGRESSIVE;
        params->reconChromaFormat = XDM_CHROMA_NA;
        dynParams->size = sizeof(IH264FHDVENC_DynamicParams);
        dynParams->refFrameRate = 30000;
        dynParams->forceFrame = IVIDEO_I_FRAME;
        dynParams->refFrameRate = 30000;
        dynParams->targetFrameRate = 30000;
        dynParams->targetBitRate = 10000000;
        dynParams->generateHeader = XDM_ENCODE_AU;
        dynParams->captureWidth = 0;
        dynParams->interFrameInterval = 0;
        dynParams->mbDataFlag = 0;

I change only set :

        params->maxHeight = 720;
        params->maxWidth = 1280;

and :

    dynParams->inputWidth    = 1280;
    dynParams->inputHeight   = 720;

rateControlPreset = CBR; (don't remember the exact value)

I use Gstreamer to encode my video stream, and get the fps via dmaiperf :

gst-launch -v ticapturesrc .... ! TIPrepEncBuf ... ! queue max-size-buffer=3 ! TIVidenc1 engineName=codecServer codecName=h264fhdvenc ... ! dmaiperf print-arm-load=true ! fakesink silent=true

Hope it help you.

Mika

Thank you very much Mika, I will try it.

One more question - do you get an indication from the Codec that it works at 720P60?

What do you mean ?

In documentation i don't remember if it tells that.

But i controlled the information at output and i get 60 frames by second with a resolution of 1280 x 720. (see my pipeline in previous post).

I get the problem from another point :

H264enc takes more than 16.66666ms  (1/60) to encode a frame. (about 33ms)

h264fhdvenc takes about 13.3ms so ...

Understood, I see that you don't change the frame rate to 60000, you keep it 30000, correct?

I forwared your reply to my colleagues (Michele and Michael) who work on it, they may be in touch with you. Thanks in advance,

The framerate doesn't seem to have any issue on it. I let it at 30000 and it didn't "lower" my framerate.

No prob, you/they are welcome !

One question for you :

Are you using Gstreamer ?

Mika

No, we are not using Gstreamer. We are using Live555.
