It also presents last minute information that did not make it into the manual or on-line help. Note that this text file serves to complement your manual. The information found in this file overrides your formally documented material. Contents 1. The Matrox Encode/Decode filters for DirectShow®. 1.1 Differences between MIL 10 Update 10 and MIL 10. 1.2 What's new in MIL 10 Update 10. 1.2.1 New feature summary 2. Supported operating systems. 3. Location of examples (in the help file) ------------------------------------------------------------------------------- 1. The Matrox Encode/Decode filters for DirectShow®. 1.1 Differences between MIL 10 Update 10 and MIL 10. - New Matrox Encode Filter. - New Matrox Decode Filter. - New Intel QSV engine implementation. - Added an example named MilEncodeDecode. 1.2 What's new in MIL 10 Update 10. 1.2.1 New feature summary - Addition of Matrox Encode filter. IMilSequenceEncode is the interface class and it inherits from IBaseFilter. Its GUID is IID_IMilSequenceEncode. The filter can be allocated using its GUID: CLSID_MilSequenceEncode. These are defined in MilDSFCapture.h and MilDSFCaptureGUID.h IMilSequenceEncode methods: * Control and inquire functions are equivalent to MseqControl and MseqInquire except that you do not have to specify ContextSeqId and SequenceIndex. * STDMETHODIMP InitParam(MIL_UINT32 OutputFormat, MIL_INT64 InitFlag) Synopsis: Sets the sequence context initialization parameters and internally reallocates the context if necessary. Parameters: * MIL_UINT32 OutputFormat: Specifies the format of the output data generated by the encoding M_DEFAULT: Specifies the default output format. i.e.: For encoding it would represent H.264 * MIL_INT64 InitFlag: Specifies the underlying hardware or software used for the encoding. See the InitFlag parameter of MseqAlloc in the MIL Reference section from the MilHelp for details about supported values. * STDMETHODIMP GetInitFlag(MIL_INT64* pInitFlag) Synopsis: Retrieves the InitFlag originally set by the InitParam function. Parameters: * MIL_INT64* pInitFlag: Specifies the address in which to write InitFlag. - Addition of the Matrox Decode filter. IMilSequenceDecode is the interface class and it inherits from IBaseFilter. Its GUID is IID_IMilSequenceDecode. The filter can be allocated using its GUID: CLSID_MilSequenceDecode.

Parameters: * MIL_UINT32 OutputFormat: Specifies the format of the output data generated by the decoding M_DEFAULT: Specifies the default output format. * MIL_INT64 InitFlag: Specifies the underlying hardware or software used for the decoding. See the InitFlag parameter of MseqAlloc in the MIL Reference section from the MilHelp for details about supported values. * STDMETHODIMP GetInitFlag(MIL_INT64* pInitFlag) Synopsis: Retrieves the InitFlag originally set by the InitParam function. Parameters: * MIL_INT64* pInitFlag: Specifies the address in which to write InitFlag. - New Intel QSV engine implementation. Used latest QSV implementation to enable the hardware acceleration without having to enable a display on the Intel GPU. This feature is only available under Windows 8 with the Intel 3rd generation and higher Intel® Core™ processors. - New example for Matrox Encode/Decode filter An example of the DirectShow filter named MilEncodeDecode is present in \Users\Public\Documents\Matrox Imaging\Mil\Examples\DirectShow\MilEncodeDecode\ The example shows how to program with the Matrox Encode/Decode filter for DirectShow®. 2. Supported operating systems. This section lists all the supported operating systems. - 32-bit Windows® 7 - 64-bit Windows® 7 - 32-bit Windows® 8 - 64-bit Windows® 8 3.
