Hi Ravi I saw the change to query for format type in 10254/2 ; however that is just a call to mDataSource->GetDataSourceFormatType which would return PVMF_FORMAT_UNKNOWN for audio/video codecs. The format is recognized in the Engine [ we know the right format in recognizecompleted(), which is still before Sink components have been initialized by playerdriver , however it is not updated back to the iDataSource ; and hence the next query to mDataSource->GetDataSourceFormatType stil returns PVMF_FORMAT_UNKNOWN. iDatasource does not have provide a way to SetDataSourceFormatType without changing some interfaces.
