Enables video processing by the Source Reader.	b1ec1c0e-8042-4486-822f-eb106577c0b1	MF_SOURCE_READER_ENABLE_VIDEO_PROCESSING attribute (Mfreadwrite.h)	reference	05/31/2018

MF_SOURCE_READER_ENABLE_VIDEO_PROCESSING attribute

Enables video processing by the Source Reader.

Data type

UINT32

Value	Meaning
Nonzero	Enable video processing.
Zero	Disable video processing. (Default)

 

Get/set

To get this attribute, call IMFAttributes::GetUINT32.

To set this attribute, call IMFAttributes::SetUINT32.

Remarks

If this attribute is TRUE (nonzero), the source reader can perform the following limited video processing on uncompressed video frames:

• Conversion from YUV to RGB-32.
• Deinterlacing.

These operations are performed in software, and are not optimized for playback. This feature is intended for applications that process a small number of frames—for example, to create a video thumbnail—or applications that do not decode frames in real time. The deinterlace operation interpolates data from a single field, so it is lossy.

Avoid this setting if you are using Direct3D to display the video frames, because the GPU generally provides better video processing capabilities.

If this attribute is TRUE, the following attributes must be FALSE:

• MF_SOURCE_READER_D3D_MANAGER
• MF_READWRITE_DISABLE_CONVERTERS

Requirements

Requirement	Value
Minimum supported client	Windows 7 [desktop apps | UWP apps]
Minimum supported server	Windows Server 2008 R2 [desktop apps | UWP apps]
Header	Mfreadwrite.h
