Sets pointers of surface->Info.Data to actual pixel data, providing read-write access.
In case of video memory, the surface with data in video memory becomes mapped to system memory.
An application can map a surface for read access with any value of mfxFrameSurface1::Data::Locked, but can map a surface for write access only when mfxFrameSurface1::Data::Locked equals to 0.
Note: A surface allows shared read access, but exclusive write access. Consider the following cases:
@li Map with Write or Read|Write flags. A request during active another read or write access returns MFX_ERR_LOCK_MEMORY error immediately, without waiting.
MFX_MAP_NOWAIT does not impact behavior. This type of request does not lead to any implicit synchronizations.
@li Map with Read flag. A request during active write access will wait for resource to become free,
or exits immediately with error if MFX_MAP_NOWAIT flag was set. This request may lead to the implicit synchronization (with same logic as Synchronize call)
waiting for surface to become ready to use (all dependencies should be resolved and upstream components finished writing to this surface).
It is guaranteed that read access will be acquired right after synchronization without allowing another thread to acquire this surface for writing.
If MFX_MAP_NOWAIT was set and the surface is not ready yet (for example the surface has unresolved data dependencies or active processing), the read access request exits immediately with error.

Used to control the encoder behavior during reset. By using this structure, the application
instructs the encoder to start a new coded sequence after reset or to continue encoding of the current sequence.
This structure is also used in mode 3 of the MFXVideoENCODE_Query function to check for reset outcome before actual reset. The application
should set StartNewSequence to the required behavior and call the query function. If the query fails (see status codes below), then reset is not
possible in current encoder state. If the application sets StartNewSequence to MFX_CODINGOPTION_UNKNOWN, then the query function replaces the coding option with the
actual reset type: MFX_CODINGOPTION_ON if the encoder will begin a new sequence after reset or MFX_CODINGOPTION_OFF if the encoder will continue the current sequence.
Using this structure may cause one of the following status codes from the MFXVideoENCODE_Reset and MFXVideoENCODE_Queryfunctions:
@li MFX_ERR_INVALID_VIDEO_PARAM If a reset is not possible. For example, the application sets StartNewSequence to off and requests resolution change.
@li MFX_ERR_INCOMPATIBLE_VIDEO_PARAM If the application requests change that leads to memory allocation. For example, the application sets StartNewSequence to on and
requests resolution change to greater than the initialization value.
@li MFX_ERR_NONE If reset is possible.
The following limited list of parameters can be changed without starting a new coded sequence:
@li The bitrate parameters, TargetKbps and MaxKbps, in the mfxInfoMFX structure.
@li The number of slices, NumSlice, in the mfxInfoMFX structure. Number of slices should be equal to or less than the number of slices during initialization.
@li The number of temporal layers in the mfxExtAvcTemporalLayers structure. Reset should be called immediately before encoding of frame from base layer and
number of reference frames should be large enough for the new temporal layers structure.
@li The quantization parameters, QPI, QPP and QPB, in the mfxInfoMFX structure.
The application should retrieve all cached frames before calling reset. When the Query API function
checks for reset outcome, it expects that this requirement be satisfied. If it is not true and there are some cached frames inside the
encoder, then the query result may differ from the reset result, because the encoder may insert an IDR frame to produce valid coded sequence.

/*!
Used to control composition of several input surfaces in one output. In this mode, the VPP skips
any other filters. The VPP returns an error if any mandatory filter is specified and returns the filter skipped warning if an optional filter is specified. The only
supported filters are deinterlacing and interlaced scaling. The only supported combinations of input and output color formats are:
- RGB to RGB,
- NV12 to NV12,
- RGB and NV12 to NV12, for per the pixel alpha blending use case.
The VPP returns MFX_ERR_MORE_DATA for additional input until an output is ready. When the output is ready, the VPP returns MFX_ERR_NONE.
The application must process the output frame after synchronization.
The composition process is controlled by:
- mfxFrameInfo::CropXYWH in the input surface defines the location of the picture in the input frame.
- InputStream[i].DstXYWH defines the location of the cropped input picture in the output frame.
- mfxFrameInfo::CropXYWH in the output surface defines the actual part of the output frame. All pixels in the output frame outside this region will be filled by the specified color.
If the application uses the composition process on video streams with different frame sizes, the application should provide maximum frame size in the
mfxVideoParam structure during the initialization, reset, or query operations.
If the application uses the composition process, the MFXVideoVPP_QueryIOSurf function returns the cumulative number of input surfaces, that is, the number
required to process all input video streams. The function sets the frame size in the mfxFrameAllocRequest equal to the size provided by the
application in the mfxVideoParam structure.
The composition process supports all types of surfaces.
All input surfaces should have the same type and color format, except for the per pixel alpha blending case, where it is allowable to mix NV12 and RGB
surfaces.
There are three different blending use cases:
- <b>Luma keying.</b> All input surfaces should have the NV12 color format specified during VPP initialization. Part of each surface, including the
first one, may be rendered transparent by using LumaKeyEnable, LumaKeyMin, and LumaKeyMax values.
- <b>Global alpha blending.</b> All input surfaces should have the same color format, NV12 or RGB, specified during VPP initialization. Each input surface, including the first one, can be blended with underlying surfaces by using GlobalAlphaEnable and
GlobalAlpha values.
- <b>Per-pixel alpha blending.</b> It is allowed to mix NV12 and RGB input surfaces. Each RGB input surface, including the first one,
can be blended with underlying surfaces by using PixelAlphaEnable value.
It is not allowed to mix different blending use cases in the same function call.
In the special case where the destination region of the output surface defined by output crops is fully covered with destination sub-regions of the
surfaces, the fast compositing mode can be enabled. The main use case for this mode is a video-wall scenario with a fixed destination surface
partition into sub-regions of potentially different size.
In order to trigger this mode, the application must cluster input surfaces into tiles, defining at least one tile by setting the NumTiles
field to be greater than 0, and assigning surfaces to the corresponding tiles by setting the TileId field to the value within the 0 to NumTiles range per
input surface. Tiles should also satisfy the following additional constraints:
- Each tile should not have more than 8 surfaces assigned to it.
- Tile bounding boxes, as defined by the enclosing rectangles of a union of a surfaces assigned to this tile, should not intersect.
Background color may be changed dynamically through Reset. There is no default value. YUV black is (0;128;128) or (16;128;128) depending
on the sample range. The library uses a YUV or RGB triple depending on output color format.

In the VP9 encoder it is possible to divide a frame into up to 8 segments and apply particular features (like delta for quantization index or for
loop filter level) on a per-segment basis. "Uncompressed header" of every frame indicates if segmentation is enabled for the current frame,
and (if segmentation enabled) contains full information about features applied to every segment. Every "Mode info block" of a coded
frame has segment_id in the range of 0 to 7.
To enable Segmentation, the mfxExtVP9Segmentation structure with correct settings should be passed to the encoder. It can be attached to the
mfxVideoParam structure during initialization or the MFXVideoENCODE_Reset call (static configuration). If the mfxExtVP9Segmentation buffer isn't
attached during initialization, segmentation is disabled for static configuration. If the buffer isn't attached for the Reset call, the encoder
continues to use static configuration for segmentation which was the default before this Reset call. If the mfxExtVP9Segmentation buffer with
NumSegments=0 is provided during initialization or Reset call, segmentation becomes disabled for static configuration.
The buffer can be attached to the mfxEncodeCtrl structure during runtime (dynamic configuration). Dynamic configuration is applied to the
current frame only. After encoding of the current frame, the encoder will switch to the next dynamic configuration or to static configuration if dynamic configuration
is not provided for next frame).
The SegmentIdBlockSize, NumSegmentIdAlloc, and SegmentId parameters represent a segmentation map. Here, the segmentation map is an array of segment_ids (one
byte per segment_id) for blocks of size NxN in raster scan order. The size NxN is specified by the application and is constant for the whole frame.
If mfxExtVP9Segmentation is attached during initialization and/or during runtime, all three parameters should be set to proper values that do not
conflict with each other and with NumSegments. If any of the parameters are not set or any conflict or error in these parameters is detected by the library, the segmentation
