Want to pass H264 data from IMFSample to cloud

Question

Hi,

(Media Foundation Class based)

I am receiving H264/H265 stream from camera asynchronously through "OnReadSample". I would like to pass H264/H265 data to a cloud, not IMFSample type. Please suggest and show me a link to working example if possible.

Thanks
GD

I see, you can use [ConvertToContiguousBuffer][1] and IMFMediaBuffer::Lock to get the byte buffer.

IMFMediaBuffer *mediaBuffer = NULL;  
BYTE *pData = NULL;  

  
pSample->ConvertToContiguousBuffer(&mediaBuffer);  
hr = mediaBuffer->Lock(&pData, NULL, NULL);
