逐帧使用原始数据字节进行播放

Question

我有一个由H264编码的字节流。现在我想使用Media Foundation播放我将帧作为原始数据而没有容器，我逐帧接收它。任何人都知道我该怎么做？

下面的代码片段演示了如何从字节缓冲区创建IMFSample对象。获得IMFSample后，可以将其输入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);
