anyone help to interpret what is HRESULT -1072868846? I found http://msdn.microsoft.com/en-us/library/ee719669%28VS.85%29.aspx but none of the listed ones match...
the function i'm calling is
hr = m_pReader->SetCurrentMediaType(
(DWORD)MF_SOURCE_READER_FIRST_VIDEO_STREAM,
NULL, pType);
With err.exe from the Platform SDK:
# for decimal -1072868846 / hex 0xc00d5212
MF_E_TOPO_CODEC_NOT_FOUND mferror.h
# No suitable transform was found to encode or decode the
# content. %0
# 1 matches found for "-1072868846"
Converting it into hex with calculator in programmer mode and searching for the hex works well too.
