problem to use SDK functionality

[stsybikov]

Hi,

Sorry if I created the thread in wrong forum. I don't know where address my issue to.

I have the following problem using Intel media SDK.
Several months ago I downloaded the trial version of Intel Parallel Studio to do the evaluation. I was able to encode YUV 420 video stream to h264, mpeg2 and mpeg4 video files. Also I was able to mux them as well. Several times I did extension of Studio trial version. When all periods expired I was unable to do the encoding. No target files had been created.

Finally the company bought the official version of Intel Parallel Studio XE 2011 for Windows. I took a fresh copy of Windows XP and installed Microsoft Visual Studio 2010 and Parallel Studio. Finally I was able to compile my code. When I run my part I got the same result as with expired trial version.

The problem is here:
UMC::FileWriter writer;
UMC::FileWriterParams params;
...
writer.Init(&params);

Init() call returns UMC::OK but the file physically is not created. Initially when I used trial version during this call file is created normally with 0 kb size.

Does anyone have the idea what the problem could be?

Thanks in advance

Hi Sergey,

UMCs are sample classes shipped with IPP, not Intel Media SDK.

Regarding the UMC::FileWriter object, you should associate it with a UMC::Muxer object; please post a code sample to clarify the problem.

Hi, Tamer;

You are right. This is IPP.
This is extraction from my code. I tried to do it more simple.



UMC::FileWriter Writer;
UMC::FileWriterParams WriterParams;
wcscpy_s(WriterParams.m_file_name, _T("C:\\target.mpg"));

return;

while(bRun)
{
DataVideoIn.SetBufferPointer(pVideoFrameBuffer, 3110400);
DataVideoIn.SetDataSize(pReader->m_nVideoBufferSize);

DataVideoOut.SetBufferPointer(pOutputVideoData, 100000000);

status = Mpeg2Encoder.GetFrame(&DataVideoIn, &DataVideoOut);
if (status == UMC::UMC_OK)
{
nEncodedVideoFrames++;

int nDataSize = DataVideoOut.GetDataSize();
MuxVideoData.SetBufferPointer(pOutputVideoData, nDataSize);

memcpy(MuxVideoData.GetDataPointer(), DataVideoOut.GetDataPointer(), nDataSize);

MuxVideoData.SetDataSize(nDataSize);
MuxVideoData.SetTime(nEncodedVideoFrames*((double)1.0)/24);
