H264VideoEncoder problem to process GetFrame

Hi Intel Gurus,

I have the problem with H264VideoEncoder to encoder the file with smaller resolution size rather than original frame data size.

I have YUV420 1920x1080 buffer with data and the sample of my code:

UMC::Videodata DataIn;

UMC::MediaData DataOut;

Int FrameSize;

UMC::H264EncoderParams Params;

UMC::H264ViveoEncoder H264Encoder;

Params.key_frame_control.method = 1;

// If I have define width as 1920 and height as 1080 everything works great,

// If define a different width and height H264Encoder.GetFrame(…) crashes pointing to the memory allocation.

Params.info.clip_info.height = height;

Params.info.clip_info.width = width;

Params.info.bitrate = 10000000;

Params.info.framerate = 24;

Params.numThreads = 1;

H264Encoder.Init(&Params);

FrameSize = FrameWidth*Frameheight*3/2; //1920*1080*3/2

Ipp8u* pOutputData = ippsMalloc_8u(FrameSize);

DataIn.Init(FrameWidth, Frameheight, UMC::YUV420, 8); // 1920, 1080

DataIn.SetBufferPointer(pYUVFrameBuffer, FrameSize);

DataIn.SetDataSize(FrameSize);

DataOut.SetBufferPointer(pOutputData,10000000);

H264Encoder.GetFrame(&DataIn, &DataOut); // the code crashes in this point

Any idea why H264Encoder crashes ??????????????
