A question about H264 encoder on DM6437

han shuai

Hello:

I'm a newer on DSP. Recently I'm writing a program on H264 encoder,but when process() is called ,an error code outArgus.entendedError =1 is returned.I have tried my best to solve this promble ,but it is still unresolved. Please help me find the problem.Thank you!

The parameters configuration are as follows:

IVIDENC1_Params *pParams;

pParams->size      =sizeof(IVIDENC1_Params);
pParams->encodingPreset    =XDM_DEFAULT; //Default setting of encoder
pParams->rateControlPreset =IVIDEO_LOW_DELAY;//CBR rate control
pParams->maxHeight     =288;
pParams->maxWidth      =720;
pParams->maxFrameRate      =30*1000;
pParams->maxBitRate        =2000000;
pParams->dataEndianness    =XDM_BYTE;//Big endian stream
pParams->maxInterFrameInterval = 1;//no B frame
pParams->inputChromaFormat = XDM_YUV_422ILE;//YUV 4:2:2 interleaved (little endian)
pParams->inputContentType = IVIDEO_PROGRESSIVE;//Interlaced,top field.
pParams->reconChromaFormat = XDM_CHROMA_NA;

IVIDENC1_DynamicParams * pDynParam;

pDynParam->size                             = sizeof(IVIDENC1_DynamicParams);
pDynParam->inputHeight              = 288;
pDynParam->inputWidth               = 720;
pDynParam->refFrameRate        = 30*1000;
pDynParam->targetFrameRate   = 30*1000;
pDynParam-> targetBitRate         = iBitRate;
pDynParam->intraFrameInterval = 30;
pDynParam->generateHeader    = XDM_ENCODE_AU;     //Encode entire access unit, including the header
pDynParam->captureWidth        = 0;
pDynParam->forceFrame           = IVIDEO_NA_FRAME;      //No forcing of any specific frame type for the frame
pDynParam->interFrameInterval = 1;             // to use IVIDENC1_Params.maxInterFrameInterval.
pDynParam->mbDataFlag         = 0;

Hi,

Which version of DVSDK or codec s/w are you using ? Are you trying the standard test application provided with the codec package ?

regards

Yashwant

First, thanks for your reply.The version of SDK I use is 3.0,and codec_engine_2_10_02. I have download the H264 encoder demo from the TI.But after being downloaded into the board, the same problem appeared again. I have tried to solve it for a long time without any resolut, so I come here for help!

Hi Han,

Please share the version of codec used and also the error code retuned once encoder exits process call.

Thanks,

Roopesh

Hi:

First, thank you! But I did not understand you, I have showed the version of codec which is 2_10_02, and the error code returned is 1 which means that error during sequence parameter generation. Could you explain again?

Hi Han,

I was referring to version of H.264 encoder used, not the codec engine. Please refer to the release notes to get this info.

Thanks,

Roopesh

Hi:

I see. The version of the encoder is 02.02.00.

Thanks.

Hanshuai.

Hi Hanshui,

Thanks. Please set 'Encoding preset' to 'XDM_USER_DEFINED' for encoding to happen with your setings. With 'XDM_DEFAULT', encoding proceeds using default values. Also, please refer to release notes to check if right tools are used(i.e. Framework, BIOS , Code geneartion tools). Thanks,

Roopesh
