Hi Prem,
Thanks for the reply. when I say that improper output it means it is giving
some data output after every 30 frames.
using following printf i get the output shown below.
printf("Encoded framesize %d %d %d\n", outArgs.bytesGenerated,
outArgs.encodedFrameType, outArgs.inputFrameSkip);

when i feed this 1740 bytes of data to decoder it produce a pink white
output screen & gives no error.
Below is the absolute value of parameters & these same values works properly
for H264 codec.
params.size = sizeof(VIDENC1_Params);
params.encodingPreset = XDM_DEFAULT;
params.rateControlPreset = IVIDEO_LOW_DELAY;
params.maxBitRate = 6000000;
params.dataEndianness = XDM_BYTE;
params.maxInterFrameInterval = 1;
params.inputChromaFormat = XDM_YUV_422ILE;
params.inputContentType = IVIDEO_PROGRESSIVE;
params.maxHeight = 576;
params.maxWidth = 720;
params.reconChromaFormat = XDM_CHROMA_NA;
params.maxFrameRate = 30000;
dynamicParams.size
= sizeof(VIDENC1_DynamicParams);
dynamicParams.inputHeight = 576;
dynamicParams.inputWidth = 720;
dynamicParams.targetBitRate = 1500000;
dynamicParams.intraFrameInterval = 30;
dynamicParams.generateHeader = XDM_ENCODE_AU;
dynamicParams.captureWidth = 0;
dynamicParams.forceFrame = IVIDEO_NA_FRAME;
dynamicParams.interFrameInterval = 1;
dynamicParams.mbDataFlag = 0;
dynamicParams.targetFrameRate = 25000;
dynamicParams.refFrameRate = 25000;
