How to config Param&DynamicParam for h264fhdvenc?

Shaquille Wu

I have create the codec of h264fhdvenc successfully,

but there are 2 problems about the configurations for Param&DynamicParam

1.when I call venc1_control( , GETBUFINFO, &DynamicParam, &status), it gives the result of status as following:

minNumInBufs of H264 is 2
InBufSize[0] of H264 is 2088960
InBufSize[1] of H264 is 1044480
minNumOutBufs of H264 is 1
OutBufSize[0] of H264 is 0

it is obviously that the OutBufSize[0] is wrong, it should be (2088960 + 1044480), but the return value of venc1_control is 0(success). so i am very confused.

2.when I call venc1_control( , SETPARAM, &DynamicParam, &status), it failed, and it's return value is 57344

I think the above two problem are reference to the configurations of Param&DynamicParam. Is there anyone teach me how to config these parameters?

my configurations for Param&DynamicParam as followings:

g_paraH264.videncParams.size   = sizeof(IH264FHDVENC_Params) ;
g_paraH264.videncParams.encodingPreset  = XDM_DEFAULT ;
g_paraH264.videncParams.rateControlPreset = IVIDEO_LOW_DELAY ;

g_paraH264.profileIdc    = 66 ; //BASELINE_PROFILE
g_paraH264.levelIdc    = 40;
g_paraH264.EntropyCodingMode   = 0 ; //CAVLC

g_dpH264DynParams.videncDynamicParams.inputHeight = 1920;
g_dpH264DynParams.videncDynamicParams.inputWidth = 1088;
g_dpH264DynParams.videncDynamicParams.refFrameRate =30000;
g_dpH264DynParams.videncDynamicParams.targetFrameRate = 30000 ;
g_dpH264DynParams.videncDynamicParams.targetBitRate = 10000000 ;
g_dpH264DynParams.videncDynamicParams.intraFrameInterval= 30;
g_dpH264DynParams.videncDynamicParams.generateHeader = XDM_ENCODE_AU ;
g_dpH264DynParams.videncDynamicParams.captureWidth = 0 ;

g_dpH264DynParams.videncDynamicParams.forceFrame = -1 ;
g_dpH264DynParams.videncDynamicParams.interFrameInterval= 0 ;
g_dpH264DynParams.videncDynamicParams.mbDataFlag = 0 ;

g_dpH264DynParams.QPISlice    = 28 ;
g_dpH264DynParams.QPSlice    = 28 ;
g_dpH264DynParams.RateCtrlQpMax    = 51 ;
g_dpH264DynParams.RateCtrlQpMin    = 0 ;
g_dpH264DynParams.NumRowsInSlice   = 0 ;
g_dpH264DynParams.LfDisableIdc    = 0 ;
g_dpH264DynParams.LFAlphaC0Offset   = 0 ;

g_dpH264DynParams.ChromaQPOffset   = 0 ;
g_dpH264DynParams.SecChromaQPOffset   = 0 ;

g_dpH264DynParams.OutBufSize = -1;

Hi,

Which platform is this ?

Yashwant

the platform is DM6467, call these interface through Codec_Engine in Linux, and the alg is in DSP.

Could you give me some suggestion?

Thank you very much

I have SET_PARAMETER in successfully through changing some parameters.but the "GET_BUFINFO" problem is still as past.

now, i have a further question that is about MaxSlicesSupported_IFrame&MaxSlicesSupported_PFrame, they are require configurations as followings as the UserGuide prompting :

Valid range is >0
Default Values:
90 for 30fps
263 for 25fps
306 for 24fps
948 for 15fps

but my device is just 10fps, so i want to know how to set these two parameters when my fps is 10?

Another question is that I setting intraframeinterval = 10 in the dynamicparameter, but i just get i-frame as normal after calling "process", the other frame is abnormal.

Because the other 9 frames' size(the generateBytes of outarg) are 12 or 11. so i think they are abnormal.

my basice steps as following:

dynamicparameter.intraframeinterval = 10;

dynamicparameter.forceframe= -1;

control(,SET_PARAM,)

while(1)

{

process(.....);

}

who can help me?

Is there anyone would tell me how to solve these problems?

Sorry Shaquille for delay.

I will remind Mahentesh to get back on this.

Shaquille,

Please find the following inputs on your queries,

1. With GETBUFINFO control call: Verify the content of the following parameter for OutBufSize, and also confirm once again for any error code returned by the encoder.

sStatus->videncStatus.bufInfo.minOutBufSize[0]

2. In setting params:

Make sure that the size of dynamic params class is also calculated as below,

g_dpH264DynParams.videncDynamicParams.size = sizeof(IH264FHDVENC_DynamicParams);

3. MaxSlicesSupported for I and P:

Keep the minimum default value like "948 ( for 15fps)" even though you are setting for 10 fps.

Mahantesh

Thank you very much, Mahantesh

1.about GETBUFINFO, the return value of this function is 0, but the sStatus->videncStatus.bufInfo.minOutBufSize[0] is 0, so i am very confused

2.about the size of DynamiceParam, I have checked my codes, the g_dpH264DynParams.videncDynamicParams.size is sizeof(IH264FHDVENC_DynamicParams)

3. about MaxSlicesSupported for I and P, thanks for your suggestion.

My current problem is:

1. GETBUFINFO, its state is still as past: return value is 0, but minOutBufSize[0] is 0

2.I cannot get P frame as normal, becuase just the size of I frame is normal, the size of P frame is abnormal(always 12).

Note:

my width is setting as 1920

my height is setting as 1088

Hi Shaquille,

To obtain non zero value in "minOutBufSize[0]" during the GETBUFINFO control call, the following flag should be assigned to -1, please confirm once again the same,

dynamicparams.OutBufSize = -1;

Mahantesh

Hello, Mahantesh

I have checked my codes, my dynamicparams.OutBufSize is set as -1

I am more confused now , it seems that there is not any person can help me

My fhd264enc and hdvicp are all download from TI's website, and they are all latest

0 Mahantesh S Madiwalar over 14 years ago in reply to Shaquille Wu

TI__Intellectual 1790 points

Hi Shaquille,

Fine I will analyze further on this and let you. In the mean time the hdvicp version "1.01.020" should be used for the H264 encoder library version "01.10.02.05" you are using. So please confirm this as well.

Mahantesh

Hello, Mahantesh

Thanks for your analyzing.

My version of h264fhdvenc&hdvicp is the same as you said.

Is there any possibilities that my version of dvsdk&codec engine are not suitable for h264fhdvenc&hdvicp that you mentioned ?

my dvsdk version is dvsdk_2_00_00_22

my codec engine version is codec_engine_2_23_01

0 Mahantesh S Madiwalar over 14 years ago in reply to Shaquille Wu

TI__Intellectual 1790 points

Hi,

Can any body from DVSDK team please help Shaquille's query, that the above mentioned h264fhdvenc&hdvicp releases can work using the following DVSDK and CE tool versions,

dvsdk version: dvsdk_2_00_00_22

codec engine version: codec_engine_2_23_01

I am almost despair now, you still remeber my problem, thank you very much Mahantesh!

do you think my low framerate cause this problem? my frame rate is < 10 fps

0 Mahantesh S Madiwalar over 14 years ago in reply to Shaquille Wu

TI__Intellectual 1790 points

Hi Shaquille,

Lower frame rate is not at all related to getting "OutBufSize[0] = 0", it looks some compatibility issue with the DVSDK version whatever you are using. So, do you got this h264 encoder library version "01.10.02.05" along with the DVSDK version "dvsdk_2_00_00_22" when downloaded from the web?

I will also try to verify the DVSDK version using which this H264 encoder runs and let you know about the same.

Regards,

Mahantesh

Hello, Mahantesh

Thanks for your reply.

I confirm that the h264 encoder is download from web of TI.

But my DVSDK is not from web, It is from a EVM board.

Hi Shaquille,

Even at our end, it's been confirmed that h264fhdvenc ver "01.10.02.05" has been not integrated in the DVSDK version "dvsdk_2_00_00_22", but this version of the encoder code base is integrated in the DVSDK version "dvsdk_3_10_00_19" onwards. So, please download this version of the DVSDK and try the same.

Mahantesh
