The code snippet below demonstrates how to create an IMFSample object from a byte buffer. Once you have an IMFSample it can be fed to the MF Enhanced Video Renderer.

MFCreateSample(&reConstructedVideoSample); 
CHECK_HR(MFCreateMemoryBuffer(srcBufLength, &reConstructedBuffer), "Failed to create memory buffer.\n"); 
CHECK_HR(reConstructedVideoSample->AddBuffer(reConstructedBuffer), "Failed to add buffer to re-constructed sample.\n"); 
CHECK_HR(reConstructedVideoSample->SetSampleTime(llVideoTimeStamp), "Error setting the re-constructed video sample time.\n"); 
CHECK_HR(reConstructedVideoSample->SetSampleDuration(llSampleDuration), "Error setting re-constructed video sample duration.\n"); 

byte *reconByteBuffer; 
DWORD reconBuffCurrLen = 0; 
DWORD reconBuffMaxLen = 0; 
CHECK_HR(reConstructedBuffer->Lock(&reconByteBuffer, &reconBuffMaxLen, &reconBuffCurrLen), "Error locking re-constructed buffer.\n"); 
memcpy(reconByteBuffer, srcByteBuffer, srcBuffCurrLen);         // srcByteBuffer is a byte * that contains the sample video data read from file.
CHECK_HR(reConstructedBuffer->Unlock(), "Error unlocking re-constructed buffer.\n"); 
reConstructedBuffer->SetCurrentLength(srcBuffCurrLen);
