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:
